給機付エンジンの排気ガス還流装置。 A recirculation passage for recirculating part of the exhaust gas is provided between the exhaust passage and the intake passage of the engine, and an on-off valve means having a diaphragm is interposed in the recirculation passage, and the diaphragm on both sides of the on-off valve means is interposed. In a supercharged engine in which a recirculation passage is controlled to open and close depending on the pressure state introduced into each chamber, both chambers of the on-off valve means respond to the engine load in the non-exhaust gas recirculation region. An exhaust gas recirculation system for a supercharged engine, characterized in that the exhaust gas recirculation device for a supercharged engine is provided with a switching valve means for controlling the pressure inlet from the intake passage to be the same and closing the recirculation passage.
