Produced by BMW, E36 are well-known parts used in car manufacturing. These parts have distinct features that make them most admired and enable modern high tech cars to perform better.

Many of the E36 parts are easily available in the market as well as one can buy them fro Internet. Following are the specifications of E36 parts:

Types of E36 Parts:

1. Wheels: Available in 18, 17, 19, and 20 inches, these tires are strong and have longer life. Moreover, they come in different colors such as silver, chrome and black. These wheels are easily adjusted in your vehicle. Considering newly emerging technologies and industrial ethics, production of these wheels is undertaken with utmost care and concentration.

2. Headlights: Made of supreme elements, headlights are other essential module of E36 parts. With exceptional form, these headlights give splendid look to your car. Made from plastic, the headlines do not consist of projector lens. Normal headlight installation will certainly not go with your E36.

3. Body Kits: In order to improve the velocity of cars, E36 has introduced these body kits. By installing these kits, you can easily control the speed of your vehicle. These kits are been made available at your nearby shops or you can also order them online.

4. Air Intake: This air intake consists of inbuilt air box. Power producing is one of the distinct and new features of these air intakes, which enables your E36 to have more cold air. Other then this, it enables your car engine to intake fresh air into its induction system.

5. Exhaust System: After going through several tests, this exhaust system is allowed on roads to make pleasant sound and good airflow. Due to quality factor, these exhaust systems are quite costly. E36 exhaust systems enhance engine quality and exhaust flow of the car.

6. Fuel Injectors: Fuel is the most significant element of your car, because the life of the car depends upon the quality of fuel. E36 fuel injectors are equipped with needle shaped valve that expel fuel under appropriate pressures. Thus, E36 Parts car gets clean fuel.

Diesel Fuel Injectors

Among engines, one major difference between Diesel and Gas is the injection process. Injectors are of two types; one is the Carburetor and the other is Port Injector. Carburetor is a system where the air and fuel are mixed together in an internal combustion engine. Whereas Port Injectors are external (meaning outside the cylinder) and injects fuel prior to intake stroke.

This process is called the Fuel optimization. A diesel engine system looks at optimizing fuel and air before they are injected into their respective chambers.

The basic design mechanism of diesel fuel system has the fuel supply line, an intake valve, an exhaust valve and the fuel injection apparatus. There are also there cylinders attached to its supply line. Fuel passes through a filter and then goes through these lines to the injector device attached with the cylinder. Finally, when the fuel reaches the injector, it is highly pressurized. Diesel fuel is sprayed into the chamber by the diesel injectors. The intake valves suck air into the cylinder and exhale value removes the emissions.

Diesel engines use the direct injectors (directly into the cylinder). Diesel fuel injectors are the most complicated ones and are found in various places in an engine. They are designed to be able to withstand the pressure undergone within and be able to deliver fuel efficiently.

One main drawback of these diesel fuel injectors is when compression of fuel and air limits the compression ration of the engine. That is when the compression is too high, the fuel and air mixtures ignites and causes Knocking. Knocking can damage the engine easily due to excessive heat. Loud noise is also one of the draw backs there direct diesel fuel injectors make.

There is always a solution to every problem; some diesel engines contain these components called Glow Plug. These glow plugs see to that the compression is not too high and prevents fuel from being ignited. Glow plugs are used in smaller engines. Larger engines use ECM, which have the ability to sense the air temperature and sprays the fuel when the engine gets too cold. This facilitates the engine to start without trouble during cold climates.

Over the years, these diesel injectors have become extremely sophisticated. These injectors have become computer regulated. Everything has become completely programmed. The injection timing and fuel amount are all electronically controlled.

In a normally operating engine, intake and exhaust valves are opened by a cam and closed by_____?

a. Rocker arms or cam follower
b.valve spring
c.Lifters(tappets)
d.Valve guide and/or pushrod

The higher position on the lube of the cam, in relation to the rest of the cam, moves the lifter up which causes the push rod to go up. The push rod pushes up on the rocker arm, which has a folcrum point, which causes the other end of the rocker arm to push down on the valve. The valve is held shut with a spring. When the rocker pushes on the valve, it overcomes the spring pressure and opens the valve. When the cam rotates, and the top of the lobe is no longer under the lifter, the spring pressure overcomes the pushrod and lifter, and thus shuts the valve.

CNG Process for Full-Size Vans Nears Completion
DETROIT, July 13 -- General Motors has finalized the production process for its Compressed Natural Gas (CNG) powered Chevrolet Express and GMC Savana full-size vans, allowing the company to deliver fleet customers complete vehicles with a fully integrated and dedicated CNG fuel system starting this fall.
