Automotive Fuel System Parts

Automobile fuel supply system is 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 system has 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 Parts Work?

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 System Parts?

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.
