Automotive Fuel System Parts
Automobile fuel supply systemis classified according to fuel supply mode: carburetor engine, EFI engine and in cylinder direct injection engine, supply to the cylinders, and make it ignite, burn and expand to do work near the end of compression. Finally, the fuel supply system should also discharge the combustion product exhaust gas into the air. Each part must work flawlessly to achieve expected vehicle performance and reliability.
Car fuel supply systemhas been widely used in automobiles because of its simple structure, convenient use and low cost. However, the main disadvantage of carburetor engine is that the inflation and mixture distribution are not ideal. It has a certain adverse impact on the improvement of engine power, economy and emission. Therefore, modern cars are basically not used. At present, the mainstream is EFI engine and in cylinder direct injection engine.
EFI engine uses electronic control device to control the fuel supply process of the engine. According to the number of injectors, EFI engine can be divided into multi-point injection and single point injection. At present, multi-point injection is mostly used. The main principle of multipoint EFI is that the injection process of gasoline fuel is in the intake manifold. If the injector is installed on the intake pipe of each cylinder, gasoline can be injected into multiple cylinders, which forms multipoint injection. The cost of gasoline injection is not only lower, but also less carbon deposition.
How Does The Automotive Fuel System PartsWork?
The fuel pump sucks the fuel out of the fuel tank, filters out the impurities through the fuel filters and enters the low-pressure fuel chamber of the fuel injection pump. After increasing the fuel pressure, fuel will be transmitted to the fuel injector through the high-pressure fuel pipe. When the fuel pressure reaches a certain value, the fuel injector sprays the fuel into the combustion chamber in the form of mist to form mixed gas and burn. After working, the waste gas will be discharged into the atmosphere through the exhaust device.
The task of fuel supply system is to prepare a certain amount and concentration of combustible mixture according to the requirements of various working conditions of the fuel engine, supply it to the cylinder, and make it ignite, burn and expand to do work near the end of compression. Finally, the supply system should also discharge the combustion product - exhaust gas into the atmosphere.
How To Wire Automobile Fuel SystemParts?
Components of automotive fuel supply system consist of fuel tank, fuel pipe, fuel pump, fuel filter, air filter, fuel pressure regulator, fuel injector, intake manifold, exhaust manifold, etc.
The task of the fuel supply system of fuel engine is to pump the fuel out of the fuel tank through the fuel pump, via fuel filter which filters the impurities and water in the fuel, then enters the fabricated fuel rail. The engine ECU sends fuel injection signals to the fuel injection nozzle according to the output signals of various sensors of the engine, ejects the fuel from the fuel injectors at a certain pressure, mixes it with the clean air obtained through the air filter in the intake manifold in a certain proportion according to the requirements of various working conditions of the engine, finally enters the cylinder, compresses, works and exhausts in the cylinder, to generate engine power.
