СИСТЕМА СНИЖЕНИЯ ТОКСИЧНОСТИ ОТРАБОТАВШИХ ГАЗОВ


  1. FUNCTION


    1. This system is designed to help reduce and control NOx formation due to a peak temperature reduction in the engine combustion chamber, which is accomplished by the introduction of amounts of inert gas into the intake manifold.

    2. By sensing the engine driving conditions and actual EGR valve opening amount, the ECM electrically operates the EGR valve assembly. As a result, the amount of recirculating exhaust gas is regulated.

    3. The ECM switches the bypass passage of the EGR cooler assembly via the EGR bypass valve switching valve in order to optimize the temperature of the EGR gas and clean exhaustgases.
