Exhaust Gas Recirculation (EGR) System
EXHAUST GAS RECIRCULATION (EGR) SYSTEMThe EGR system routes exhaust gases back through the engine to reduce emissions. When the exhaust gases exit the exhaust manifolds they enter the intake manifold through the EGR valve by either first passing through the EGR cooler or bypassing the EGR cooler depending on the position of the EGR cooler bypass valve.
