SFI SYSTEM


  1. FUNCTION


    1. The electronic SCV system mainly consists of swirl control valves, an SCV position sensor, an SCV actuator, and an ECM.

    2. The electronic SCV system closes one of the 2 independent intake ports for each cylinder according to the engine conditions. Closing the port optimally controls the airflow in the combustion chamber and enhances the charging and combustion efficiency for low fuel consumption. The SCV system is located in the intake manifold.
