ТОПЛИВНАЯ СИСТЕМА


  1. CONSTRUCTION


    1. Each injector assembly consists of a nozzle needle, a control plate and a solenoid valve.

    2. An injector compensation value and a Quick Response (QR) code containing encoded characteristics of the injector are printed on each injector.

    3. The injector compensation value and QR code contain various pieces of information regarding the injector, such as model code and injection volume correction.

  2. OPERATION


    1. When electrical current is applied to the solenoid coil, it pulls the solenoid valve up.

    2. The out-orifice of the control chamber opens, allowing the fuel to flow out.

    3. The fuel pressure in the control chamber drops.

    4. Simultaneously, nozzle needle lifts and fuel is injected.

    5. As the control valve closes, the pressure of the control camber and intermediate chamber are equalized.

    6. The control plate is pushed down by in-orifice pressure, allowing fuel to flow to the control chamber.

    7. As control chamber pressure increases, the nozzle needle closes with the force of the spring and fuel injection is stopped.

    8. When the control chamber and in-orifice pressure equalize, the control plate rises due to the force of the spring.
