INTAKE SYSTEM DETAILS


  1. CONSTRUCTION


    1. Throttle Body


      1. A linkless-type throttle body, in which the throttle position sensor and the throttle control motor are integrated, is used. It achieves excellent throttle control.

      2. A DC motor with excellent response and minimal power consumption is used for the throttle control motor. The ECM performs the duty cycle control of the direction and the amperage of the current that flows to the throttle control motor in order to regulate the opening angle of the throttle valve.

    2. Intake Manifold


      1. The intake manifold has been made of plastic to reduce the weight and the amount of heat transferred from the cylinder head. As a result, it has become possible to reduce the intake air temperature and improve the intake volumetric efficiency.

      2. This intake manifold consists of three parts, which are integrated through vibration welding.

        Tech Tips

        Vibration welding: vibration welding is a type of friction welding. In this process, one part of the work to be welded remains stationary while vibration and pressure are applied to the other part, thus causing the joining surfaces to melt and become welded. This method creates a joint that is stronger than other joining methods, such as those using adhesives.
