How the fuel pump works:

1. The working principle of the electric fuel pump is the same as that of the electric water pump. The motor drives the corresponding fuel pump device to continuously deliver fuel to the fuel system;

2. You must know that the fuel system must maintain a certain pressure. Only in this way can the fuel sprayed by the injector be better atomized and easier to burn;

3. The structure of the electric fuel pump is composed of three parts: the pump body, the permanent magnet and the shell. When the permanent magnet motor is energized, it drives the pump body to rotate, and the fuel is sucked from the oil inlet, flows through the inside of the electric fuel pump, and then is pressed out from the oil outlet to supply fuel to the fuel system;

4. The fuel flows through the inside of the electric fuel pump and cools the armature of the permanent magnet motor, also known as the wet fuel pump.
