The role of the fuel injector


The role of the fuel injector is:  

1.  Increase oil pressure (constant pressure) : increase the injection pressure to 10MPa ~ 20MPa.  

2.  Control injection time (timing) : according to the specified time injection and stop injection.  

3.  Control the amount of 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 injection pulse signal from the ECU to accurately control the amount of fuel injection.  Fuel injector is a kind of precision device with very high machining accuracy, which requires large dynamic flow range, strong anti-blocking and anti-pollution ability and good atomization performance.
