An EGR control system for a diesel engine, comprises an EGR passageway connecting an intake passageway and an exhaust passageway to recirculate engine exhaust gas back to the engine, an EGR control valve operatively disposed in the EGR passageway to control the flow of the recirculated exhaust gas passing through the EGR passageway, a detecting device for detecting at least one of engine speed, engine load and engine coolant temperature to produce at least a signal dependent thereon, and a control device for controlling the operation of the EGR control valve in response to the signal from the detecting device, thereby controlling the amount of the recirculated exhaust gas in accordance with engine operating conditions. |
