1. Improve oil pressure (constant pressure) : increase the injection pressure to 10Mpa ~ 20Mpa.

2. Control injection time (timing) : injection and stop injection at the prescribed time.

3. Control fuel injection (quantitative) : according to the working condition of the diesel engine, change the amount of fuel injection to adjust the speed and power of the diesel engine.

The injector receives the fuel injection pulse signal sent by the ECU and accurately controls the fuel injection amount. The fuel injector is a kind of precision device with very high machining accuracy,
which requires its large dynamic flow range, strong anti-blocking and anti-pollution ability and good atomization performance.
