Audi q7 diesel water hose principle

The principle of Audi q7 diesel water hose is to deliver fuel inside the engine through the fuel pump doing work. And the oil water pipe is a branch that belongs inside the fuel system. The fuel system consists of gasoline tank, fuel pump, fuel sensor, gasoline hose and so on.

The function of the fuel system is to supply a certain amount of clean, well atomized gasoline to the engine according to the needs of the engine's operating conditions in order to mix with a certain amount of air to form a combustible mixture.

One, the amount of sensor

Vehicles of all kinds of fuel tank level detection, the use of ferrite magnets generated by the magnetic field to control the reed switch contacts on and off the principle of the level of the measured changes in the liquid level is converted into an electrical signal output and the secondary instrumentation is connected to detect the level of the height of the liquid.

Second, the role of the gasoline pipe gasoline

Fuel Filter The gasoline filter cartridge is mostly used filter paper, but also the use of nylon cloth, polymer materials gasoline filter main function is to filter out impurities in gasoline. If the gasoline filter is too dirty or clogged.

Three, fuel pressure regulator

Fuel pressure regulator valve function to ensure that the fuel pressure in the automobile fuel line work properly. Pressure regulator inside a diaphragm, play a role in controlling the pressure valve to open and close the role of the oil pressure is lower than a certain value, the pressure valve is closed, pressurized by the oil pump to increase the pressure in the oil circuit, when increased to more than the prescribed pressure, the diaphragm opens, the overpressure of the fuel through the return pipeline flow back to the tank, to play the role of pressure reduction.

Four, fuel rail (also known as fuel distributor)

Fuel distributor (Fabricated Fuel Rail), also known as the fuel rail or fuel rail, it is an electronically controlled fuel injection system in the air/fuel subsystem is an integral part of the air/fuel sub-system, it is a mechanical device, installed in the intake manifold is located in the injector, its main function is to ensure that the provision of sufficient Fuel flow and evenly distributed to the injectors of each cylinder, while realizing the installation and connection of each injector.
