ABSTRACT:
An exhaust gas recirculation (EGR) system for a diesel engine comprising an EGR control valve for regulating the flow of exhaust gases to be recirculated from an engine exhaust system back to an engine air intake system. When the exhaust gas recirculation is to be interrupted, the EGR control valve is closed a predetermined time after the opening of a throttle valve used in the air intake system for regulating the flow of air towards the engine. For this purpose, delay valves are utilized in association with the throttle valve and the EGR control valve.
