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.
