Emission Control System
The engine emission control system consists of the:
^ EGR valve (EGR valve)
^ differential pressure feedback EGR
^ EGR vacuum regulator solenoid
^ EGR tube
The engine emissions control system:
^ cycles crankcase gases back through the engine intake system.
^ regulates ventilating air and blow-by fuel vapors.
^ reintroduces exhaust gases into the combustion cycle.
^ assists in the reduction of nitrogen oxides.
