INTAKE SYSTEM GENERAL


  1. OUTLINE


    1. A throttle body equipped with a rotary solenoid type throttle control motor is used.

    2. Swirl control valves are provided in the intake manifold.

    3. An air-cooled intercooler is used.

    4. A variable nozzle vane type turbocharger is used.

  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. Intake Manifold


        • The shape of the intake manifold has been changed to ensure a high swirl ratio and improve the EGR gas distribution efficiency.

        • As with the previous model, it is equipped with swirl control valves, and uses isometrical ports with surge tanks to generate an appropriate swirl for each cylinder.

        • By increasing the distance to the surge tanks, the mixing distance for the intake air and the EGR gas has been optimized and the EGR gas can be evenly distributed to each cylinder.

      2. Turbocharger


        • A compact, lightweight turbocharger is used to increase the output power and improve the emission reduction efficiency.

        • With the use of a new turbocharger with a small turbine capacity, the structure of the area around the variable nozzle vane unit has been changed.

        • As with the previous model, turbocharger control performed by the engine ECU, and a DC motor and nozzle vane position sensor are provided to ensure high responsiveness and realize feedback control.

      3. Air Intake Pipe


        • The air intake pipes have been partially changed.
