The components of the injector are the injector nozzle and the injector body. Their mounting position and angle on the cylinder head depend on the design of the combustion chamber.
The injector is a precision device with very high machining accuracy, which requires a wide dynamic flow range, strong anti-clogging and anti-pollution ability as well as good atomization performance. The injector receives the injection pulse signal from the ECU and precisely controls the fuel injection quantity.
The main role of the injector has:
1、Improve oil pressure: increase the injection pressure to 10MPa to 20MPa;
2, control the injection time: according to the specified time to spray and stop spraying;
3, control the amount of injection: according to the working conditions of the diesel engine, change the amount of injection to regulate the speed and power of the diesel engine.
