The injector is actually a simple solenoid valve. When the solenoid coil is electrified, it generates suction, the needle valve is sucked up, the nozzle is opened, and the fuel is ejected at high speed through the annular gap between the needle and the nozzle at the head of the needle valve, forming a fog, which is beneficial to full combustion.

Control of fuel injection quantity: In the same type of electric injection vehicle, the pressure of gasoline pump is constant, regardless of the throttle opening, as long as the fuel pressure regulator is adjusted, the pressure of the injector is always constant. The injector is used strictly with the fuel pump and the fuel pressure regulator. Only the designed pressure can the injector achieve the best atomization effect, and the pressure is lower than the designed pressure. The oil ejected by pressure is not columnar and not suitable for mixing with air; the oil ejected by excessive pressure is conical and not easy to mix, and the fuel ejected by too much force directly sprays onto the wall of the pipe, directly affecting the mixing ratio parameters.
