发明名称 Device for preventing an exhaust gas recirculation valve from sticking after switching off an internal combustion engine
摘要 The invention relates to an exhaust gas recirculation device for an internal combustion engine, especially for a motor vehicle, comprising an exhaust gas recirculation line for recirculating exhaust gas, the line branching off from the exhaust line and running into an unburned gas line. The exhaust gas recirculation line includes a valve having a closing element which can be displaced between a closing position and an opening position by means of an actuator. One aim of the invention is to especially reliably prevent the closing element of the valve from sticking to the valve seat after the operation of the internal combustion engine. To this end, the closing element of the valve is placed in an idle position by means of the actuator, when the internal combustion engine is not in operation.
