Automatic Transmissions:
Many car owners love their Automatic Transmissions for comfort and ease. Put it in Drive, the Torque Converter does all the work and you Go. New technologies in Automatic Transmissions are now allowing six-speed automatic transmissions. You will find these six-speed automatic transmissions in mainstream cars like the Mazda6 and Ford Five Hundred. The MINI Cooper S, made by BMW, is thinking of going with the six-speed automatic transmission in its car. Seven-speed automatics are also showing up in high end luxury cars.
CVT Transmissions:
These are also automatic transmissions, yet perform slightly differently. You still put it in Drive and go. In these transmission, I have heard you do not feel the shift like normal automatic trannys, and that they cannot transfer as much horsepower to the ground, without some type of failures. The Nissan Murano and MINI Cooper have this option, and we will see how widespread this goes.
Manual Transmissions:
The Manual Transmission is the choice of gearheads who love their cars. They live and breathe having cars with this transmission, giving them complete control of the car at all times, and how it transmits the power. These transmissions have not changed much. You still have the clutch, brake and gas combo to make it move and stop. They do in many cars now have six-speed manual transmissions, and this is not an uncommon thing. Whereas you had 4-speed manual trannys long before. Want control? You want a manual transmission.
Auto-Shifting Manual Transmissions:
BMW and Audi are the leaders in this front. BMW has its SMG (Sequential Manual Gearbox) and Audi has the DSG (Direct Shift Gearbox). I have driven neither, so I don’t have first hand experience with how they relate in control to a Manual Transmission. However, they do use a Clutch Pressure Plate like a manual transmission that is automatically shifted. The good news about that? Automatic transmissions loose roughly on average 20% of its power as it hits the wheels. With this transmission, you dont loose that power, because you do not have a torque converter, but you have an actual clutch. This is great news for people who like the option of automatic for traffic, but want the power to shift whenever they want to without loss of power. Look for more of these trannys soon, as even Volkswagen Golf’s are said to have them as an option.

The transmission is one of the most important components of your car mechanics. Without the transmission you couldn’t move faster than 20 miles per hour, bringing us back to cart and horse days. The transmission regulates the tire speed with the engine speed and sends power from the Engine System to the wheels.
You may think the engine is the most complicated component in car mechanics but actually it is the transmission, making it important to understand what the transmission does and how it does what it does. This article will cover the aforementioned topics and also covers signs of trouble with transmissions and when to get the transmission repair.
The transmission does a lot more than transfer power. It is the component at the back of the engine that connects the engine to the wheels. Its job is to keep the engine speed at a certain number of RPM (Revolutions Per Minute) because the engine works best when running at speeds that are not too fast and not too slow.
When your car is moving slowly the engine is moving much faster than the wheels. But at faster speeds the engine does not have to work as hard relative to the wheel speed. It is the transmission that makes this possible. There are a number of other gear gear positions in a typical transmission. These include “reverse,” which sends the wheels turning backwards, “neutral,” which disengages the engine from the car’s wheels, and “park” which locks the wheels so the vehicle will not move.
There are many different components to the transmission. Planetary gear sets, hydraulic system, clutches and bands, seals and gaskets, and a Torque Converter are all components put together to deliver power to your car. Planetary gear sets adjust for different speeds and reverse. The hydraulic system sends oil to the gear system through the clutches and bands. Seals and gaskets are there to keep oil where it’s supposed to be, covering the planetary gear sets, so everything runs smoothly. The torque converter is a Clutch Disc mechanism, allowing the gears to change without stopping.
There are many ways to tell if your transmission is working smoothly or giving you trouble. For example, failure to shift, or delays in shifting are a strong indication that your gear sets or torque converter is having problems.
Listen closely for odd noises. Thumping, grinding, banging, whining noises and lag in shifting can be a sign of problems. If the engine speeds up when you press the gas, but the car doesn’t speed up accordingly, that tells you that your transmission isn’t functioning right. Check your fluids. Red, pink or brown fluid under the car or having to continually fill the transmission with fluid are signs that you need to bring your transmission into the shop.
Preventative maintenance means thinking ahead and checking your car against all these problems, before they start. Change the transmission fluid every 25,000 miles, as a rule of thumb. This is done by taking your car or truck to a professional, because removing the transmission fluid pan is complicated and messy. Also it is best to let your mechanic take the pan out because they can check the fluid for metal shavings and other indications of problems.
So keep your transmission up to date by regular visits to your mechanic and watch (and listen) for signs that it is starting to have problems. If you follow these two guidelines, you shouldn’t have extreme problems with your transmission.
Knowing how your transmission works can help when you are talking to your mechanic about the maintenance of your vehicle. If you ask him or her what’s going on with your engine they will be glad to help you. Understanding a bit about your transmission will help you watch for problems and have them looked after before they develop into larger issues.

Have you ever noticed when you move your car that you see stains? They may be either in your driveway or garage. Do you think, is it my car or something else? Should I have it looked at? Well if this is something you notice everyday, it’s time to figure out just what those spots are.
There are few different ways to determine what it may be leaking from your car, first finding out what it can be can lead to a decision if it’s time to take your car in for a check-up. Here are some common fluid leaks:
- If you find a yellow, greenish blue or orange, it is most like antifreeze. This could be leaking from a cracked hose or a small hole in the radiator, and possibly the Water Pump seal. This must be taken to a mechanic to be repaired to prevent your car from overheating.
- You may see dark brown or even black stains, well this can be from a leaky oil valve gasket, a head gasket or the Oil Pan itself, another thing that you should take in to be inspected.
- If you see a red, oily, slippery spot on the ground there are a few possibilities for this, all of which should be checked by a mechanic. It could mean transmission, power or brake fluid.
- If you happen to see that it is a clear water stain, this could be that your radiator has overflowed or it can simply be from the air conditioning unit emitting moisture from the humidity.
It is very important to determine the source of a leak from your car. Some leaks may be minor and not require immediate attention. However, some can cause great concern. You wouldn’t want to be driving along to find you can not use your brakes. Or in the middle of the summer and your car overheats because you lost all the antifreeze.
Every time you go to the gas station, it would be a good idea to take a look at your fluid levels. Low oil pressure or severely black oil, can blow your engine, causing thousands of dollars in repairs. If you are extremely low on power steering fluid, you may find yourself not being able to handle your car properly. Transmission fluid is something else that can cause serious issues and damage your transmission system, leaving you with costly repairs or a whole new transmission.
So the next time you see those spots or stains on the ground, get your car inspected right away to avoid possible danger to yourself or others, and also to avoid costly repairs.
My passion is to help others through their journey in life. To help those who find it difficult to follow the right path, and to teach my children to offer their hands in life. I have a great passion in giving and finding peace and hope in all types of relationships.

This is a short list of things to look for when you buy a classic car, if you do these things it will make you a lot happier with the purchase of your classic car.
1.Locate the right car for you “The Most Important Step”, this car need to excite you, it should make you feel like a diamond ring feels to a woman, you should be all giddy, just like a little school girl on her first date.
2.Make sure that you inspect the car, for rust, collision damage, leaks, make sure it doesn’t over heat wile running, look under the carpet and floor mats for rust, be sure all the gauges are working correctly, look for electrical problems, like flickering lights, or lights that don’t come on, check the blinkers, check the tail lights and brake lights, fire the engine and listen for knocks, clicks, pings and the like, these are all signs that you may have a lot of work to.
3.The test drive, look for: excessive play in the steering, engine running rough or misfiring, brakes that don’t stop the car like they should, whining from the rear end or transmission, if it has a standard transmission be fore warned if it pops out of gear, this means that synchros are going bad, and listen for a grinding sound when you press the clutch as this indicates a bad pilot bearing, and if the car has a hard time moving when you let off the clutch this indicates that the pressure plate and disk are bad. If it has and automatic transmission, look for the trans to slip, or not go in to gear like it should, pull the dipstick and look and the transmission fluid to see if it’s dark or burned, ask the owner of the car to jack up the front of it so you can move the wheels to check for bad tie rods, this is done by grabbing the wheels one at a time and wiggling the, with your hands positioned and 9 O’clock and 3′Oclock and moving the wheels back and forth.
4.Engine: pull the dipstick out of the engine and look at the oil to see if it’s black and sludgy or smells burned, and if it has a with honey looking appearance to it, this indicates a cracked head or a bad head gasket that leaks water in to the Oil Pan, look at the rocker covers to see if they leak excessive oil, also with the engine running listen for a grinding sound from the Water Pump or alternator, this indicates that these item are going bad.
5.Also I forgot to mention, while your inspecting the body of the car, be sure to look at the rocker panels for rust holes and bad body work, also look at the quarter panels for rust holes, and bad body work, and don’t forget to look at the engine compartment for rust and bad wiring.
These are all reasons for you to get a better deal on the car you choose to buy, use these factors to barter with the owner of the car, point them out and use them to your advantage.
I’ve been in the automotive business for about 20 or 25 years, I have worked in all facets of the industry, from parts to restoration, all different makes and models, I just want to keep people interested in the old cars because it’s where my heart is.

Air is very important for every natural living creature and is also very useful even for artificial and manmade moving systems. In general, air is very important to everything whether artificial or natural and that’s why you will find it very important for your Mercedes Benz especially for the engine. The system that ensures good Air Intake for Mercedes is very important as it provides sufficient oxygen to the engine for clean up and fluent oil combustion hence high speed and good performance from your Benz. If you are to install your Mercedes Benz with an air Intake system you should put into mind that you need high performance and good mileage so you should choose one that gives you the desired results.
If you ever experienced a vehicle with a noisy engine the problem is usually the air intake system. You should install your Mercedes with an air intact system that provides sufficient air to cool your car engine as well as allow efficient combustion of fuel in the engine. A cold air intake system is such a device. They come in different shapes and sizes and are therefore advantageous than other performance increasing modifications for they are easy to install and bring out the desired results. These systems of air intake for Mercedes work on the standard principle of density and mass.
Because of the high density, cool air is heavier than hot air hence replaces hot air in the engine’s cylinder therefore increasing the amount of air for fuel combustion while at the same time cools the engine. Increased amount of oxygen leads to increase in combustion hence high power output from the engine and you will find yourself flying in a matter of seconds. This is actually the performance you need and with a well selected and rightly installed system for air intake for Mercedes, you will be actually at the top of the par.
You should also ensure that the system for air intake for Mercedes has been installed at the right place to avoid hydro lock especially when you are driving in muddy terrains. Hydro lock minimizes air flow into the engine of your Benz resulting to low combustion hence poor performance. The system should therefore be installed above the hood of the engine to prevent water from reaching into the system which ensures uninterrupted flow of sufficient air for combustion. So, upgrade your Mercedes today by getting the original quality air intake!

While most people fit a cold Air Intake for the sole purpose of gaining power and making their vehicle go faster, there is renewed interest in the use of the cold air Intake by those people who wish to save fuel due to the prices they are expected to pay these days.
The cold air intake increases the performance of the engine by lowering the temperature of the air going into the engine.
By increasing the power by maximizing the efficiency of the engine the vehicle is able to do the same job that is asked of it with less effort.
By reducing the effort to travel the same piece of road there is less fuel burnt and that is where you get your fuel saving.
For most people, fitting a cold air intake will make them tend to drive faster because they will feel the extra power that the engine will be developing.
They will be able to accelerate faster and travel at higher speeds.
That is not the goal of this exercise. The car should still be driven smoothly and at the same speeds that it was before the fitting of the cold air intake to realize the fuel savings.
It only takes a small increase in efficiency for a reasonable saving of fuel and as the cost of fitting a cold air intake is minimal it is a good way to save fuel and also have the additional power when required.
Fitting a cold air intake is a job that any home mechanic can perform with the simple instructions that comes with the products.
You can save gas and drastically reduce your running expenses.

The Cylinder Head is the most important part in an engine where substantial time and effort is spent by a professional tuner. There is more power to be gained in correctly porting the head than in any other modification that it can be done to an engine.
Cylinder head porting is the process of grinding material from the ports and chamber of the cylinder head to increase the airflow and thus improve performance of an engine.
The flow efficiency of the head will determine the horsepower potential that an engine can achieve and by correctly porting the cylinder head, higher level of efficiency is achieved and the engine will extract more power.
The cylinder head consists of three important areas which are the Intake section, the combustion chamber section and the exhaust section. It is very important that all three sections are modified to work in conjunction with one another as power will suffer and engine efficiency will decrease considerably. I cannot stress this enough as every day I come across ruined heads after being ported badly and my point is that it is useless to have a huge high flowing polished inlet port and the combustion chamber is all shrouded and will not burn it efficiently or the exhaust port does not flow enough air or has a bad shape or the inlet/exhaust flow ratio is out as the engine will not produce more power or even worse decrease its power after being ported.
Another important topic is engine characteristics. Cylinder head porting needs to be accustomed to the usage that the engine will operate at. A head modified for drag racing operating between 7,000 and 10,000rpm will be useless to a rally engine needing more midrange torque and operating between 3500 and 7500rpm.
When a new client comes to our workshop for a porting job we ask several questions so that we can tailor the porting appropriately the type of driving the engine will operate in.
If the engine is going to be built in house then we know most of the answers but if a client come with just the cylinder head than we need to make sure to have all the required information so the cylinder head porting will be done accordingly.
Just to give you some idea these are some of the questions that we ask:
a) Is the engine for street use, off-road/rally, circle track or drag racing?
b) Is the engine normally aspirated, turbocharged, supercharged, NOS, or a combination?
c) Engine size, Bore, stroke, Connecting Rod length?
d) What type of fuel is going to be used? Pump fuel, racing leaded fuel, alcohol?
e) Is the engine carbureted or electronically fuel injected?
f) Will the car have a full Exhaust System or open headers?
g) Is the camshaft still stock, and if not we need full specification.
h) What is the weight of the car and type of transmission and gearing is used? Manual, auto, sequential?
i) ….etc

In my experience, most consumers could save themselves costly repairs to their motor vehicles by recognising the common signs of Cylinder Head damage. A cylinder head can blow up from something as simple as the car overheating on a hot day. Another common cause for damage to a cylinder head is to let the motor run dry without water on a long drive.
The signs that something is wrong with your cylinder head can be white smoke coming out of the Exhaust Pipe. Maybe the motor won’t start as easily if the cylinder head is damaged. Have you ever heard a car misfire when it is started. This is another sign of cylinder head damage. When you check the water levels in the radiator look to see if there are frothy white bubbles. Please don’t do this when the motor is hot as the water will be boiling and can seriously burn you. The cylinder head can cause the radiator to crack.
What can you do about it. Well, the sooner you get it seen to by an automotive specialist, the better it is for the vehicle motor and also your hip pocket. the damaged cylinder head can cause other damage to the motor if it is left untreated which will result in a bigger bill and longer time off the road.
When you need your car everyday, imagine not having it for a week?
An automotive specialist can easily diagnose the damage and complete the repairs
Love your car? Look after the cylinder head and motor in it.

Owning a car involves more than just making sure the Fuel Tank is full, that there is windshield wiper fluid in the car and that the tire pressure is not below the stated number in the owner’s manual. Everyone that owns a car should know how to change a tire, change the Oil Filter and should know how to jump start the battery in their car in case the car stalls while on the road. Jump starting a car is not as easy as it sounds and there are a handful of steps that need to be followed for the jump start to be completed successfully and safely.
The first step in jump starting a car is to park the jumper car in close proximity to the stalled vehicle. Usually most jumper cars are placed only five feet or so from the stalled car with their fronts facing each other. Just make sure that the two cars do not touch in any way. Make sure you use clean jumper cables and never let them dangle into the Basic Engine Components where they can get caught on belts or the fan. Once the jumper cables have been readied for the project, make sure the ignition is off in both cars and set the Hand Brake of each car. Make sure either car is in neutral or park. Turn off all lights and radios but put the hazards on if you are on the side of a road.
Now you can begin the jumping process. Place one of the positive jumper cables onto the positive terminal of the battery of the stalled vehicle. Then connect the other positive end of the cable to the positive end of the battery terminal in the jumper car. Now attach the negative end of the cable to the negative end of the battery terminal on the jumper car. Attach the other negative end of the cable to an unpainted metal surface on the engine of the stalled car. By doing this, the vehicle is now further grounded.
Before performing the jump start, make one final check to make sure that the jumper cables are securely attached to the vehicle and are not near any moving parts on the engine. Now you can start the jumper car and let it idle for a handful of minutes. Once the idling has been done for around five minutes you can now start the stalled car. Once the stalled vehicle is started, make sure that both vehicles stay on and have them idle for another five minutes or so. If the stalled vehicle won’t start, do not keep trying. This will lead to damage of the starter on the stalled vehicle.
Once you are able to start the stalled car you can disconnect the starter cables. Take them off in the reverse order of how you put them on. Also, do not let them touch each other or anything under the hood. To be sure that the stalled vehicle will not stall again, take it to an auto body shop for a complete battery charge and quick once over.

Windshield wipers are used in almost all kinds of vehicles in the modern world. The olden days of the world have seen the use of Wiper Linkage only in cars and other four wheeler heavy duty vehicles, whereas the present days are seeing the use of the same for even motorcycles. Such an important part used in the vehicles of the present day world needs to be of very high quality and should be able to withstand even the most rough and rainy weather conditions. The brand name, ‘Valeo’ is known to almost all the people living in this world, the Valeo produced by the company is even more popular than the name of the company. While the quality of the material used in the making of the Valeo is of very high standards, the method of fixing the angles of the blades is found to be the best in the modern times.
Since the product is of very high international standards, the name earned by the Valeo wiper blades can be deemed to be right in all aspects. The main feature that should be noted in the usage of Valeo wipers is their perfectly design structure. The blades are useful in making the cleaning of the windshields more effective and faster. The availability of the wiper blades can be assured always, as the company believes that they are the chief producers of the Wiper Blade.
They are operated by different methods which suit the vehicles they serve. The small motor wiper blades are used in vehicles that operate between short distances only. The powering systems for the Valeo wipers will be heavy duty motors of tremendous torque and power, in vehicles that go for longer distance. Interstate and connecting transport vehicles will be using wipers powered by both manual and automatic movements, so as to facilitate the wiping of rain drops in automatic mode and for general cleaning of haze and mist in the manual mode.

There is something referred to as “sludge” that can become a part of motor oil and can clog and fill up an Oil Filter to the point where oil will no longer flow out. This greasy and cake-like form that the engine oil takes on will continue to become even dirtier without proper filtrations. When this occurs, the oil viscosity increases and overtime, the engines’ speed will reduce. Other areas that sludge can pose problems include accumulating at the bottom of the oil tank where oil won’t come out of the drainage hole during an oil change and causing the oil pressure to drop. If you waited too long to change your oil and feel that you may have caused damage to some areas of your vehicle, take it into a reputable car shop for an inspection. An experience technician will inspect your vehicle and provide you with options to help get your vehicle to proper condition.
There are additional reasons to get your oil changed periodically to keep your vehicle running smoothly. Oil manufactures add what’s known as carbon polymer to motor oil in order to increase its viscosity at high temperatures and also to decrease the viscosity during low temperatures. When in use, the polymer degrades and loses the ability to adjust the engine temperatures’ viscosity which can eventually lead to Engine System wear. Also, when a vehicle does not get regular oil changes, the level of the oil in the vehicle may drop to a dangerously low level without you even knowing it. When this happens, some vehicle owners have reported that their oil cooler burns at an extremely fast pace or they experienced an oil leak. This can cause some vehicles to burn half a quart for every thousand miles it travels.
An oil change involves draining old engine oil, replacing it with new oil and replacing the engine oil filter. The following is an outline of how essential it is to have periodical oil changes for your vehicle to ensure the proper performance of the engine.
I. Keeps the engine running smoothly and clean
• Debris and microscopic wear particles can come off of several internal engine parts and find its way to the vehicles oil. When you receive an oil change, these particles are eliminated providing the engine with needed lubrication.
II. Longer Life of Engine
• Regular oil changes results in a longer lasting vehicle engine by preventing friction and wear on the engine
III. Lowers the Vehicle Emissions
• When your old, dirty oil is replaced with clean and fresh motor oil, the oil can better absorb engine by product emissions and harmful engine particles.
IV. Provides Better Gas Mileage
• Infuses the engine with quality clean engine oil that results in less friction and better lubrication. The engine runs smother and easier and provides you with more gas mileage
V. Improved Engine Performance
• When your vehicle has clean engine oil, the internal parts run smoother and easier and provide the engine with maximum mechanical output.
For proper car functioning, take your vehicle in for regular scheduled maintenance service such as getting a periodical oil change. This ensures the safety of your vehicle and allows your vehicle to run easier and smoother. With the service of a reputable car care center, you can keep your vehicle running for properly for many years.

Car maintenance has always been one of the commonplace topics for car owners. When it comes to how to do a full range of car maintenance and what can be true car maintenance, many of these owners will be puzzled, in the following are some useful tips to get rid of the dilemma.
1. Conventional oil replacement
The lubricating oil will be oxidized, aging in the use process, therefore it needs to be replaced timely or it will be mixed with sludge, coke, water, acids, PTFE rod and other products of incomplete combustion, which may significantly lower the oil anti-wear performance on the engine. Most of the cars for oil mileage is between 5000 to 10000 kilometers.
2. Replacement of the three filters
The purpose to replace the filter is to expel various impurities in the oil, prevent the engine from wear and tear, if not replacing for a long time, there will be partial block in the filter which may cause pollutants flowing directly into the engine and increase engine wear. It is also necessary to replace the Fuel Filter and Air Filter regularly. The general replacement standard is every 20000 km/on every two times replacing the filter when changing oil; every 10000 km/on every two times replace the filter when changing oil.
3. Addition
The best way to avoid dry friction effectively and protect car engine is to add anti-wear agent or wear-resisting agent when replacing the oil and filter. The anti-wear agent is made by the most slippery material that people has known at present, the Ptfe film,or we called teflon film. It can produce an ultrathin anti-wear oil film on the inner metal side of the engine, which can fill up the tiny sunken hole produced by engine wear and tear, thus the friction resistance can be reduced and save 55 to 12% of the fuel, and repair worn surface, extend engine life 2 to 3 times, lower noise, improve emissions.
4. Cooling System
Cooling system failure is the leading killer of the engine failure, accounting for 60%. Using tap water as cooling medium, the billed water may produce scale and gathered in the radiator, which may influence the normal heat dissipation. In cold season, once the temperature dropped to below 0℃, the water will freeze and expand, even crack the water tank and the cooling system pipe. While, the no water cooling liquid has overcome all the shortcomings of the media with water or water.
5. Deep maintenance
The most important thing of car maintenance is the cleaning and maintenance of all the engine circulation system. Such as the cleaning and maintenance of engine Fuel System can effectively decompose the engine coke and improve the working efficiency. The cleaning and maintenance of engine Lubrication System can fully enhance the service life of the engine power. And the cleaning and maintenance of the engine cooling system can increase engine power, reduce oil consumption and extend engine life.

Air bags are designed to keep people safe when an accident occurs. While they started out as an optional addition available only in select vehicles, air bags are now a standard safety feature in cars sold throughout America. Typically there is an Air Bag for both the driver and the passenger, and some models have begun to include side bags as well. While these safety mechanisms can help to cushion the impact of a collision, they can also cause serious injury if they are defective or malfunction. Causes of Air Bag Injuries Unfortunately sometimes the mechanism designed to save your life can end up doing more harm than good. A defective air bag can be a danger if left unaddressed and may result in serious injuries. Some of the common defects that may cause harm to a driver or passenger include: Bag deploying with too much force
Defective sensor mechanism that fails to trigger the bag’s deployment in a collision
Bag fails to fully inflate and does not cushion the crash victim properly
Bag deploys spontaneously when there is no collision, causing injury and possibly an accident Any of these defects can cause serious harm to a driver or passenger in a vehicle. While automobile manufacturers will often report a recall for a defective product, it may take many months or even years for the manufacturer to learn of the scope of the defect and inform its customers. In that long time period, many people may be at risk of being hurt by a defective air bag. Seeking Compensation When an air bag does not perform as it is expected to, it may not keep an occupant safe as advertised and may even end up causing more harm. If you have been hurt because of a defective bag beside Door Panel, you may have grounds to pursue a personal injury lawsuit. Vehicle manufacturers have a responsibility to produce reliable and safe products, and when they fail to do so, they may be held accountable for injuries and damages that result. A personal injury lawyer can help you determine if your vehicle manufacturer is responsible for your failed air bag and will work to gather all available evidence for your case. Car accident injuries can be physically, emotionally, and financially costly, but you do not have to face the burden alone. You may be entitled to compensation from the liable manufacturer and may receive payment for your medical bills, lost wages from time off of work by Idle Motor, recovery costs, and pain and suffering.

When your car, truck, SUV or van is involved in an accident, the Air Bag sensors are the first components to detect the crash. In earlier vehicles, these sensors were basic switches that responded to changes in velocity as the vehicle slowed down during the crash. Once two sensors “closed” to confirm that a crash was taking place, electrical current was allowed to flow to the air bag of Exterior Trimming Accessories. In newer vehicles, electronic sensors measure the deceleration (negative acceleration) of the vehicle, process it mathematically through a computer algorithm, and then compare the measured values to the values stored inside it from crash testing. If the measured values indicate the crash is more severe than the stored crash tests, the control module would allow electrical current to flow to the air bag modules. Once the electrical current is flowing to the air bag modules, it heats up a “squib” within the inflater that has a small filament inside a container of chemically explosive or flammable material. Once the filament gets hot enough, the chemicals begin to burn. This burning sets off a larger reaction of a chemical called sodium azide within the inflater, which rapidly produces nitrogen gas, along with numerous byproducts. In some vehicles, the sodium azide inflater was replaced with an inflater using pressurized gas, usually a combination of helium and argon. With either type of inflater, the gas from the inflater then fills the fabric air bag that was folded over the inflater. As the gas fills the air bag, it increases in size, eventually breaking out from behind its plastic cover, and inflating to its maximum size. Driver air bags are generally shaped like a round pancake just larger than the diameter of the Steering Wheel, and are normally about 12 to 20 inches thick when filled. Passenger air bags are generally about 2 to 3 feet wide, and fill the space between the passenger and the dash or windshield. Thus, passenger air bags are usually 2 to 4 times larger than driver air bags, and require a more forceful inflater to fill that larger size in the same amount of time. For frontal air bags, the process of sensing the crash and inflating the air bags is usually over in less than one-tenth of a second. As the forces of the crash propel the consumer forward into the air bag, it begins to absorb the energy by compressing and letting some of the gas out through the fabric or specially-designed vent holes. This explains why many consumers who have been involved in an accident during which air bags have deployed remember the distinct chemical odor of the inflation gas and recall seeing smoke in the car. For side air bags and rollover air bags, the process is similar. A sensor in the side structure of the car, or sometimes inside the front door, detects the rapid deceleration from the side or the vehicle beginning to rotate upwards during a rollover crash. Electrical current is then sent to the side air bags or to the rollover air bags (depending on the type of crash), which causes those air bags to deploy. Although the chemicals and gases may be different than for front air bags, the inflation process is very similar. When a side air bag deploys, it breaks out either from the side of the seat nearest the door, or from behind a plastic trim panel on the side of the car. They are much flatter than the frontal air bags and sometimes smaller (some older side air bags protected only the person’s chest, while others protected both the chest and head). Canopy or rollover air bags deploy from overhead and are also fairly flat, but extend along the side of the vehicle to protect the head and chest and reduce the risk of the consumer being ejected through an open or shattered window. What I have described here is the general function of a typical air bag system. The air bag system is fairly complex. Therefore, a failure or defect in any one of the components can cause the entire system to malfunction. In some cases, air bags have deployed in very minor crashes (or even when there is no crash), which can lead to devastating results. In other cases, due to improper design and testing, air bags have failed to deploy in head-on frontal collisions. Some of these airbag non deployments have occurred even when the closing speed has been over 60 miles per hour.

Back in the 1970′s when the EPA decided it really had to do something about pollution from cars, it’s less than brilliant conclusion was reached. Let’s burn the unburned gasoline AFTER it comes out of the engine and Water Pump! Am I the only one who thinks this is a complete joke? If its “unburned” gasoline then wouldn’t it make more sense to burn it INSIDE the engine? The Vast majority of the pollution comes from “unburned” gasoline, so let’s burn it after it comes out of the engine to reduce the pollution. Wouldn’t it make more sense to burn it Inside the cylinder where it would give you better gas mileage? Of course it would, unless there’s some kind of unwritten mandate Car Mp4 to NOT improve gas mileage. Back in 1979 or 1980, the Moodymobile made national news by driving up to Washington, DC with the number 84 mpg painted across the side of the car. What Moody did was put a small diesel engine into a Capri, then turbo charged it. Typically he was getting 79 – 84 mpg. But when the EPA got done detuning it so that it met emission standards, it was down to only 27 mpg. What? If anyone can explain that to me, please do. Here we have a vehicle getting 84 mpg out of 1 gallon of diesel and Head Rest which somehow causes MORE pollution than the same vehicle only getting 27 mpg! Something’s rotten in Denmark folks! Can the physics of a hydrocarbon chain (diesel fuel) possibly yield MORE NOx, CO, and CO2 when its propelling a vehicle 3 TIMES further? I don’t think so. The Moody patent for the turbo charging a diesel did get bought and applied, you now see them in Mercedes, the TDI Golf from VW, and numerous cars all over Europe. Here’s my main concern: what if some little guy figured out a way to double the mileage in Big Rig 18 Wheelers, are we so heavily regulated now that it would be killed due to a lack of funds to get it past the EPA?

Copper is one of the most used metals since the days of yore. And the reason for this is its malleability and ductility. Moreover, it is a good conductor of both heat and Engine System, and is also resistant to corrosion. Its positive response to electricity makes it an ideal choice for use as raw material in electronics and related devices. Among the various electrical appliances where this metal is used are in copper wire, electromagnets, busbars, electrical relays, cable harness and switches. Nowadays, even in integrated circuits and printed circuit boards aluminum is being increasingly replaced by copper. And this is due to the superior electrical conductivity of this metal over aluminum. Again its superior heat conductivity makes it ideal for use in computer heat sinks manufacture. Recently, it is used in vacuum tubes, cathode ray tubes, and the magnetrons in microwave ovens. Wiring Harness too comes in different varieties as per the requirements of different industries like industrial variety, electrical & electro-mechanical wire harness, multi-conductor harness cable, security wire harness, medical equipment harness assemblies, passive component-to-wire harnesses, board assemblies, control, panel wiring assemblies and many more. Nowadays, you can also get custom specific cable harnesses like power supply cord that are designed for only your specific requirements. Almost all these make use of copper as raw materials. Also there are copper cable harnesses that are used in automotive industry like those used for buses, trucks, and other four wheelers. Elevators also use harnesses for lifts in multistoried building as per the specifications of the elevator manufacturers. Then there are also special harnesses that are used in home appliances like refrigerators, televisions extension cord, and many more. However, before ordering any wiring harness that uses copper, always make sure that they are highly durable and comply with prescribed standards and norms of industry, for quality performance. Copper is probably the only metal that is so versatile and used in such diverse applications like biomedical auto equipment, aquaculture applications and also architecture and industry.

Nowadays, cars are no longer considered as luxury, but rather necessity. The world today is fast moving and every day, we cover large distances for our work and other needs. Basically, the major source of transportation is our cars, such that we really need to properly maintain our cars. Vehicles have hundreds of components that are subject to wear and tear. Moreover, various weather conditions also have a huge impact on these components. Often times, vehicles are even exposed to extreme weather conditions such as heat and snow. Unfortunately, these extreme weather conditions can cause a lot of damage to car parts and may even cause these parts to break down. However, with proper care and maintenance, this can be avoided and the life of cars can be extended. More than anything else, it is really very important to regularly maintain your cars. Many people may not know this, but keeping regular care of your car increases your gas mileage. Consequently, this would translate into savings. With today’s difficult times, every penny saved is already worth a lot. A car that is poorly maintained will definitely not run as well as one that is regularly maintained. Moreover, proper maintenance also assures safety. If the various components of the car are regularly checked, you are assured that these will function properly. It should be noted that safety on the road should be the utmost concern of any driver. Thus, with a properly maintained car, you are not only saving your own life, but others as well. Luckily, you don’t really have to worry about caring for your car parts at all. There are a number of shops that does the work for you. In fact, you will be amazed at how good the Car Care Products in these shops are. Some of these amazing car care products include rubber care, wheel cleaning, glass spray, wax, and interior care products to name a few. You will be truly awed as to how these products take care of your cars and make them glitter and shine like you’ve never seen before. However, it is not enough to be awed by the promises of car care products that are just printed on their labels. You need to make sure that these products live up to their promise. As such, you should be careful in choosing car care products most especially that there are a lot of products in the market that are not really of good quality. To ensure that you choose the best quality, it is advisable to consult car specialists. Moreover, you should choose products that are credible and tested already. Some of the most credible products are those that are German engineered. In addition, it is helpful to buy from established suppliers, more preferably for European auto Brake Pad. Although choosing high quality car care products might be a little more costly, the small difference in the price cannot really suffice to the significant difference in the results. Thus, if you want only the best for your car, you should choose best value high quality Pipe Tube.

When it comes to choosing the right Exhaust System for your vehicle, the task can be an overwhelming process with a ton of variables. There are so many questions that need to be answered that are enough to make your head spin. Most of us are not automotive experts. We hear a vehicle pull up next to us or have a buddy who owns a restored muscle car that sounds awesome but have no idea what causes the car to sound so good. Well, the answer is simple. The proper way to make any vehicle sound deep and aggressive is to add an after market performance exhaust system into the mix. Now that you know how to make your vehicle sound cool, where do you go from there? There are literally dozens of manufacturers out there that will tell you that their line of exhaust products is exactly what you need to solve your problems and satisfy your need to achieve that deep resonating thunder coming from under your car. Hands down, Magnaflow exhaust systems are an industry standard that will help you achieve everything you want. Magnaflow has a solid reputation in the industry for having unbelievable quality and long lasting products that have a great limited lifetime warranty attached. For the money, which is about average priced, you simply cannot do better than Magnaflow exhaust systems. Or can you? In recent light of the success of Magnaflow exhaust systems, a fantastic line of performance exhaust Brake Caliper have come into the game with guns blazing and with the pedal to the metal. From the makers of Cherry Bomb mufflers and Arvin Meritor/Arvin Supreme exhaust products, comes a performance line of superior exhaust systems and mufflers that will do everything Magnaflow systems can do and do them just a bit better. This product line is known as Volt performance auto parts. Let me explain. Magnaflow’s main selling points in the market are the fact that all of their products feature stainless steel finish and a straight through design, perfect for achieving great sounding results without all of the metallic sounding fluff that a lot of the other imitators out there produce. Magnaflow exhaust systems feature 409 stainless steel, which is an inferior grade of stainless steel that is far surpassed by 304 stainless steel. Guess what? Volt performance exhaust systems are all made using 304 stainless steel! Yes kids, this grade of stainless will last much longer and will not rust out nearly as fast over time. Magnaflow also features a straight through muffler design which limits the amount of pressure in the muffler chamber causing a solid deep sound. Volt performance Car Care Products also feature a straight through design achieving the same effect that Magnaflow does. The best part though is that Volt performance systems, even with their more impressive 304 stainless and quality warranty, are actually about 30% cheaper in price. That’s right folks. You can get a better product for less money. How can this fact be possible? When you purchase a Magnaflow exhaust system, you are also purchasing a brand name. It costs a lot of money to maintain a brand name, so Magnaflow charges more for their products to cover these costs. Maremont, the manufacturer behind the Volt line of performance exhaust products does not concern themselves with being the biggest dog on the block. What they do care about is delivering a quality product to those people who do not have a ton of extra cash on hand but still want to have an awesome sounding vehicle. So, for your money, Volt is definitely the way to go. You can find the full line of Volt performance auto products at OverstockExhaust.com [http://www.OverstockExhaust.com]. There you can find pictures, vehicle applications, prices, free shipping and fast delivery time frames. I have used OverstockExhaust.com in the past and I continue to use them for all of my own projects and soon you will find out what most of the world already knows. Volt performance auto products are definitely the best way to go when you want to buy a great system like a Magnaflow exhaust system.

Plastic components are being used more and more in industry nowadays because of the ease of manufacturing these parts as well as the low cost of producing them. While most of the engineered plastic components can be used as produced and provide the necessary functions, there are several instances where one needs to increase the life of these plastic components by increasing the surface wear resistance. This is because plastics and polymers are inherently less wear resistant than corresponding metallic components, this in site of significant advances in plastic materials technology. In this article, we will describe one method of increasing the wear resistance of plastic component surfaces and that is by using thermal spray coatings. Thermal spray coatings allow for the deposition of various Car Body parts, ceramics and cermets on to various surfaces to modify their surface characteristics. Generally in the deposition of thermal spray coatings on to substrates, the temperature of the substrate being coated does not reach very high temperatures, even though high temperatures are used to energize the coating particles that reach the plastic state and bond to the underlying substrate and thus form the coating. Thermal spray coatings can thus be used to coat a very high wear resistant material such as tungsten carbide on to the surface of a plastic component and thus derive the benefits of a highly wear resistant surface imparted to the plastic component. The recommended process of Drivetrain spray coatings to improve the wear characteristics of a plastic component would follow the simple steps of cleaning the component to rid of all contaminants. Engine System is recommended if it can be performed without causing distortion. If grit blasting is unacceptable, then a high quality bond coat of nickel aluminum such as Metco 450NS or nickel chrome aluminum such as Metco 443NS is recommended. A twin arc wire process using a bond wire such as Tafa 75B is also acceptable. Follow the bond coat with a top coat of tungsten- carbide-cobalt that can be applied using the plasma spray coating process and you are done with the surface improvement process. Ensure that you utilize the services of a well reputed thermal spray coatings house that has a good grip on parameters and processing and you will be amazed at the tremendous improvement in life enhancement of your engineered plastic components.

The load that a transformer carries without heat damage can be increased by using an adequate Cooling System. This is due to the fact that a transformer’s loading capacity is partly decided by its ability to dissipate heat. If the winding hot spot temperature reaches critical levels, the excess heat can cause
the transformer to fail prematurely by accelerating the aging process of the transformer’s insulation. A cooling system increases the load capacity of a transformer by improving its ability to dissipate the heat generated by electric current. In other words, good cooling systems allow a transformer to carry more of a load than it otherwise could without reaching critical hot spot temperatures. One of the more common types of transformer cooling equipment is auxiliary fans. These can be used to keep the radiator tubes cool, thereby increasing the transformer’s ratings. Fans should not be used constantly, but rather only when temperatures are such that extra cooling is needed. Automatic controls can be set up so that fans are turned on when the transformer’s oil or winding temperature grows too high. Maintenance of Cooling Systems * Dry-Type Transformers:For dry-type transformers, the area in which the transformer is to be installed should have proper ventilation. This ventilation should be checked prior to installation to make sure it is adequate. Additionally, the transformer’s radiator vents should be kept clear of obstructions
that could impede heat dissipation. * Forced Air: If the transformer’s temperature is being kept at acceptable levels by forced air from a fan, the fan’s motors should be checked periodically to make sure they are properly lubricated and operate well. The thermostat that ensures the motors are activated within the preset temperature ranges should be tested as well. * Water cooled systems: Systems that are cooled by water should be tested periodically to make sure they operate properly and do not leak. Leaks can be checked by raising the pressure within the cooling system, which can be done in various ways. If the cooling coils can be removed from the transformer, internal pressure can be applied by adding water. Otherwise, pressure checks can also be made using air or coolant oil, if the coils need to be checked within the transformer itself. If the cooling coils are taken out of the transformer, the water cooling system as a whole can be tested. Here, the coils are filled up with water until the pressure reaches 80 to 100 psi, and left under that pressure for at least an hour. Any drop in pressure could be a sign of a leak. The other equipment linked to a water-cooled system can be tested at the same time, such as the alarm system, Water Pump and pressure gauges. Also, the water source should be tested to make sure it has sufficient flow and pressure. *Liquid coolants: When oil coolants are prepared they are dehydrated, and processed to be free of acids, alkalis, and sulfur. They should also have a low viscosity if they are to circulate easily. If a transformer is cooled by oil, the dielectric strength of the oil should always be tested before the
transformer is put into service. Types of Cooling Systems For oil immersed transformers, the options for cooling systems are as follows: * Oil Immersed Natural Cooled (ONAN): Here, both the core and the windings are kept immersed in oil. The transformer is cooled by the natural circulation of this oil. Additional cooling can be provided by radiators, which increase the surface area over which a large transformer can dissipate heat. Types of Cooling Systems * Oil Immersed Natural Cooled
* Oil Immersed Air Blast
* Oil Immersed Water Cooled
* Forced Oil Air Blast Cooled
* Forced Oil Natural Air Cooled
* Forced Oil Water Cooled
* Forced Directed Oil and Forced Air Cooling * Oil Immersed Air Blast (ONAF): In this case air is circulated and the transformer cooled with the help of fans. Fans allow one to have a smaller transformer for a given rating, since not as much surface area is needed for heat dissipation. This in turn can cut costs. * Oil Immersed Water Cooled (ONWN): Here the transformer is cooled by an internal coil through which water flows. This method is feasible so long as there is a readily available source of a substantial amount of water, which is not always the case. This kind of cooling has become less common in recent years, abandoned in favor of Forced Oil Water Cooled (OFWF). * Forced Oil Air Blast Cooled (OFAF): In this case, cooling is accomplished in two ways. Oil circulation is facilitated by a pump, and fans are added to the radiators to provide blasts of air. * Forced Oil Natural Air Cooled (OFAN): For this type of cooling, a pump is included within the oil circuit to aid in oil circulation. *Forced Oil Water Cooled (OFWF): Here, a pump within the oil circuit forces the oil to circulate out through a separate heat exchanger in which water flows. The most dependable type of cooling system for a transformer is the oil-immersed naturally cooled (ONAN), which also produces the least noise. A forced-air cooled transformer (OFAF) is more efficient, but it is also noisier and less reliable on account of the possibility of fan malfunction. The method of forced Brake Disc has been used for many years now to increase the loading capacities of transformers. A transformer’s thermal performance can be directly improved by the implementation of cooling systems. Consequently, it makes sense to avoid excess heating and accelerated aging within a transformer by using the appropriate cooling system.
