FUEL SYSTEM GENERAL


  1. OUTLINE


    1. A common-rail system is used in the fuel injection system.

    2. An HP3 type supply pump, which is compact and lightweight, is used.

    3. An injector compensation value and a QR code are printed on the injector to realize high-precision control.

    4. On models for Singapore, a fuel filter warning switch, which turns ON/OFF when the internal vacuum of the fuel filter increases, is provided in the fuel filter.

    5. A fuel cooler is used in the fuel return path.

  2. MAJOR DIFFERENCE


    1. The major differences between the 1KD-FTV engine mounted in the previous Dyna 100/150 and the 1KD-FTV in the new Dyna 100/150 European models are as follows.


      1. Injector


        • New high-response injectors that are able to withstand high pressure are used. A common-rail and a supply pump with the same specifications as in the previous model are also used.

        • As with the previous model, the injectors are individually controlled using the QR (Quick Response) code, making them suited to high-accuracy fuel injection control.

      2. Fuel Cooler


        • The water-cooled type fuel cooler that was attached to the cylinder block has been abolished. Accordingly, the leakage pipe has been partially changed. The air-cooled type fuel cooler is still used.
