Used Heavy Truck Parts Network 

To make a truck engine run, it would primarily need a good fuel system with, of course, an appropriate fuel to match with the engine need. The main function of the fuel system is to store and supply fuel to the cylinder chamber where it mixes with air, gets vaporized, and ultimately burns to produce energy to power the engine. The fuel, which is either a diesel or a gasoline, is stored in a truck's fuel tank where it is drawn by a fuel pump from the fuel tank through the fuel lines where it is delivered through a fuel filter to a carburetor or a fuel injector. Then it is delivered to the cylinder chamber for burning of energy or combustion. These days, most cars are already using fuel injectors rather than mechanical pumps using a carburetor.

The Difference Between Carburetors and Fuel Injectors

Although carburetors are still being used in some countries, they are gradually being pulled out from the market in order to meet the international emissions directives and to improve performance. The basic difference between carburetors and fuel injectors is that fuel injectors acts as a fuel atomizer and atomizes the fuel by forcibly pumping it through a small nozzle under high pressure, while a carburetor relies on low pressure produced through the intake of air rushing through it to add the fuel to the airstream. Since the use of carburetors is being discouraged, alternatives to mechanical pumps using carburetor include common rail diesel systems and electronic unit direct injection systems. With the use of an advanced and up-to-date fuel injector, your truck engine is guaranteed to have a finer control of injection volumes and higher pressure compared to mechanical systems.

The Basic Function of a Fuel Injector

The fuel injector is basically a nozzle and a valve. It doesn't have a hand in terms of drawing out fuel because the power to inject the fuel comes from a pump or a pressure container farther back in the fuel supply. The main purpose of a fuel injector is to accurately inject fuel to the cylinder chamber and to accurately meter and atomize fuel. A fuel injector, which is an electro-mechanical valve, reacts in split seconds to open and close and it gives electronic control unit maximum control over fuel flow to the engine.

Maintenance and Repairs

Just like any other engine system part, a fuel injector needs replacement when it is affected by the following circumstance:

• Corrosion due to moisture in the fuel
• Contamination of the fuel system
• Contamination by particles as little as 10microns

By replacing your fuel injector, you would restore its original spray pattern, improve the mixture formation of fuel resulting to enhanced total engine performance, and reduce rough running due to non-uniform spray dynamics. To ensure that you would be getting the best quality of fuel injector, purchase your supplies from trusted manufacturing companies and have the part replaced by an automotive expert for best results.
