CONSTRUCTION
A water-cooled type No. 1 EGR cooler is used between the exhaust manifold and electric EGR control valve assembly. In the water-cooled type No. 1 EGR cooler, engine coolant flows through eight-layered gas passage to cool down the EGR gas.
The No. 2 EGR valve assembly is used. The EGR gas passage is switched in 2 stages by the No. 2 EGR valve assembly to optimize the temperature of the EGR gas.
