EGR Valve: Description and Operation
EXHAUST GAS RECIRCULATION VALVE The
Exhaust Gas Recirculation (EGR) Valve is situated between the Exhaust Manifold and Collector. After the
Engine Control Module (ECM) opens the EGR solenoid valve, the
EGR valve is able to receive throttle port pressure on diaphragm. Part of the exhaust gas is then recirculated into the collector chamber.
