Custom Fuel Injector

The working principle of the fuel injector is that when the electromagnetic coil is energized, a suction force is generated, and the needle valve is attracted and lifted, opening the spray holes. The fuel is ejected at high speed through the annular gap between the tip of the needle valve and the spray hole, forming a mist.
