Injector ECU received the injection pulse signal sent to precisely control the amount of fuel injection.
Injector is a precision machining device is very high precision, requiring a large dynamic flow range, anti-clogging and anti-pollution ability and good atomization performance.
Electronic fuel injector is the common rail system, the most critical and most complex components, but also the design, the most difficult part of the process. ECU by controlling the solenoid valve on and off, the fuel in the high-pressure rail with the best injection timing, fuel injection and injection rate into the combustion chamber. In order to achieve an effective injection start point and accurate fuel injection, the common rail system uses a dedicated injector with hydraulic servo system and electronic control unit (solenoid valve).
Injector from the traditional injector with a hole nozzle, hydraulic servo system (control piston, control hole, etc.), solenoid valve and other components.
