EMISSION CONTROL SYSTEM(w/ Canister Pump Module)


  1. FUNCTION OF MAIN COMPONENTS

    Component Function
    Vacuum Sensor Assembly Detects the pressure in the intake manifold and sends signals to the ECM.
    EGR Valve Assembly Opens and closes based on signals from the ECM and controls the flow rate of the exhaust gas in the EGR bypass.
    EGR Cooler Assembly The EGR cooler assembly cools the exhaust gas to improve EGR efficiency.
    Hybrid Vehicle Control ECU Sends signals such as the accelerator pedal position sensor signal to the ECM.
    ECM Based on the signals received from the sensors, the ECM determines the EGR volume in accordance with the engine operating conditions.

  2. SYSTEM CONTROL


    1. For the EGR system, a regulated amount of inert gas is allowed to flow into the intake passage, reducing the peak temperature in the engine combustion chamber.

    2. By sensing the engine driving conditions and actual amount of the EGR valve opening, the ECM operates the EGR valve and throttle control motor, to regulate the amount of the exhaust gas that is recirculated.
