D6D D4D Fuel Injector Cover Normally Closed Valve

D6D D4D fuel injector cover fuel injector is a normally closed valve

product description

1. When the electromagnetic coil is energized, suction 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 needle and the nozzle hole at the head of the needle valve, forming a mist, which is conducive to full combustion.
2. The fuel injector itself is a normally closed valve. The normally closed valve means that the valve is always closed when no control signal is input; while the normally open valve means that when there is no control signal input, the valve is always open. The valve needle moves up and down to control the opening and closing of the valve.
3. When the ECU issues a fuel injection command, its voltage signal will cause the current to flow through the coil in the fuel injector to generate a magnetic field to suck up the valve needle and open the valve so that the fuel can be ejected from the fuel injection hole.
