СИСТЕМА СНИЖЕНИЯ ТОКСИЧНОСТИ ОТРАБОТАВШИХ ГАЗОВ


  1. CONSTRUCTION


    1. A bypass with an EGR cooler bypass switching valve is added to the EGR cooler.

    2. If EGR gas is cooled down in the EGR cooler with light engine load, compression air temperature decreases. To prevent this, the EGR gas passage is switched by the EGR cooler bypass switching valve.
