ТОПЛИВНАЯ СИСТЕМА ДЕТАЛЬНОЕ ОПИСАНИЕ


  1. SYSTEM CONTROL


    1. Diesel EFI System


      1. In this system, the ECM sends signals to the injection pump in order to control the injection timing, injection volume and idling speed.

  2. CONSTRUCTION


    1. Injection Pump Assembly


      1. A VE distribution type electronically controlled injection pump is used.

      2. A spill control valve, timing control valve, fuel temperature sensor, engine speed sensor, and injection pump correction unit is used on the injection pump.

    2. Fuel Filter Assembly


      1. The fuel filter assembly consists of a separate filter element and a filter housing.

      2. A paper filter element that offers high filtering efficiency and captures the minutest particles is used.

      3. A fuel filter warning switch is provided in the fuel filter assembly.

  3. OPERATION


    1. Fuel Filter Assembly


      1. When the water in the sedimenter section reaches a certain amount, the fuel sedimenter level warning switch comes on, the warning light in the combination meter assembly illuminates, and the multi buzzer sounds.

      2. A fuel filter warning switch, which turns on or off when the internal vacuum of the filter increases, is provided in the fuel filter. This switch, which turns off when the internal vacuum of the fuel filter increases to a predetermined level, is connected by wire to the meter ECU.

      3. When the meter ECU detects that the internal vacuum of the fuel filter has increased (by way of the fuel filter warning switch off signal), it determines that the fuel filter has become clogged. Then, it illuminates the fuel system warning light on the combination meter assembly to urge the driver to replace the fuel filter.
