Injector 0445120217 Nozzle

Injector 0445120217 Fuel injector nozzleDLLA146P1339 is the most critical and complex part in common rail system, and it is also the most difficult part in design and process. By controlling the opening and closing of the solenoid valve, the ECU injects the fuel in the high-pressure fuel rail into the combustion chamber with the best fuel injection timing, fuel injection quantity and fuel injection rate.

 

In order to achieve an effective of DLLA146P1339 injector’s fuel injection starting point and precise fuel injection quantity, common rail system uses a special fuel injector nozzle with hydraulic servo system and electronic control element (solenoid valve).

 

The fuel injector nozzle DLLA146P1339 is composed of an orifice nozzle which similar to traditional fuel injector, a hydraulic servo system (control piston, control metering hole, etc.), a solenoid valve, etc.

 

 

The Function of Fuel Injector Nozzle DLLA146P1339 Of Injector 0445120217

 

  1. Increase oil pressure (constant pressure): Increase injection pressure to 10 ~ 20 MPa.
  2. Adjust fuel injection time (timing): Controls starting and stopping fuel injectionat specified time.
  3. Adjust the fuel injection quantity (quantitative): According to the working conditions of diesel engine, change the fuel injection quantity to adjust the speed and power of diesel engine.
