My company's main products are the plunger, injector, fuel pump, fuel injection nozzle, plunger below small make up for everybody introduction of fuel injection process:

A, the injector is equivalent to the solenoid valve.

B, energized when the electromagnetic coil of electromagnetic force, the armature and valve suction, injector opening, gasoline spray hole is sprayed into the inlet pipe

C, power the electromagnetic force disappears, the armature and valve under the action of the reset spring spray hole is closed, the injector to stop the fuel injection.

D, the injector is energized, cut off by the electronic control unit to control electric pulse.

E, fuel injection quantity by electric pulse width is determined. The pulse width = = fuel injection duration

F, general needle lift is about 0.1mm, and the injection duration in the range 2~l0ms
