EGR Valve: Description and Operation
EGR Valve:
The Exhaust Gas Recirculation (EGR) valve increases or decreases the flow of
exhaust gas recirculation. As vacuum applied to the
EGR valve diaphragm overcomes the spring force, the valve begins to OPEN. As vacuum weakens, the spring force closes the valve.
