FUEL SYSTEM COMPONENTS AND FUNCTIONS

Fuel system - welcome to our topic today is the fuel system. In this discussion, we discuss the introduction of the fuel system, the basic components of the fuel system, the fuel pump, the fuel line, the fuel filter, the carburetor fuel injector. the introduction of the fuel system all in turn the engine requires three things. to run air-fuel in the spark fuel system is very important and store and deliver the gasoline or diesel fuel your engine needs to run it, think of it as your vascular system with heart fuel pump fuel lines blood vessels in the kidneys filtering failure in the wrong This one component fuel system has the same devastating effect as on your body. the basic components of the fuel tank the fuel system is basically a storage tank for fuel. when you fill up at the gas station the gas travels down the feeding tube into the tank in tank there is a sending unit that tells the gas gauge how much gas is in the tank in recent years the fuel tank got a little more complicated that way.

Now it often houses the fuel pump and has more emission controls to prevent steam from leaking into the fuel pump. the air in newer cars the fuel pump is usually installed in the fuel tank, older cars have the fuel pump attached to the engine or on the frame rail between the tank and the engine if the pump is in the tank on the frame rail then it is electric and is run by the car battery You. a fuel pump fitted to the engine uses engine motion to pump fuel-driven most often by the camshaft but sometimes the crankshaft fuel line.

There are three types of diesel fuel lines including the heavy duty high-pressure line found between the injection pump and the injector medium scale line. for light or moderate fuel pressures found between the fuel tank and injection pump and remote light channels where there is little or no net fuel filter pressure the fuel is essential for engine life and performance the fuel injectors and carburetors have small openings that clog easily so fuel filtering is a must. filters can be before or after the fuel pump sometimes both are most often made of paper elements but can be stainless steel or synthetic materials and are designed for single use in most cases.

Some performance fuel filters will have a washable net that eliminates the need for replacement fuel injectors for most domestic cars after 1986 and earlier foreign cars came from the factory injected fuel instead of carburetors to mix fuel and air. the computer controls when the fuel injector opens to let fuel into the engine this has resulted in lower emissions and better fuel economy the fuel injector is basically a small electric valve that opens and closes with an electric signal

In the picture, you can see the injector towards the outside of the intake by injecting a little.If it is not near the cylinder head, the fuel remains atomized in small particles so that it will burn better when ignited by a spark plug carburetor, the carburetor picks up fuel and mixes it with air without intervention computers while simple operation tends to require frequent tuning and rebuilding this is why newer cars have ditched carburetors for your fuel injection.
