Yes, the fuel injection process of EFI diesel vehicle and EFI gasoline vehicle is similar. One of the important bases of fuel injection is the crankshaft position sensor, which provides an important parameter, namely the crankshaft timing signal. When fuel is injected into the cylinder, it is mainly influenced by the crankshaft position sensor.

Fuel nozzle: The fuel nozzle is a normally closed valve. When the electromagnetic coil is energized, the suction force is generated, the needle valve is sucked up, the nozzle hole is opened, and the fuel is ejected at a high speed through the annular gap between the shaft pin at the head of the needle valve and the nozzle hole, forming a mist, which is beneficial to full combustion. The valve needle moves up and down to control the opening and closing of the valve. When the ECU sends the fuel injection instruction, its voltage signal will make the current flow through the coil in the fuel injector, generate a magnetic field to attract the valve needle and open the valve, so that the fuel can be ejected from the fuel injection hole. The biggest advantage of jet fuel supply is that the control of fuel supply is very accurate, so that the engine can have the correct air-fuel ratio in any state, which not only keeps the engine running smoothly, but also conforms to the norms of environmental protection laws and regulations.
