装置。A negative pressure responsive exhaust recirculation control valve is installed in the exhaust recirculation passage from the exhaust passage to the intake passage of an internal combustion engine equipped with an exhaust turbo supercharger. A negative pressure control valve is interposed between the exhaust gas recirculation control valve and the negative pressure source, and an orifice is interposed between the exhaust gas recirculation control valve and the negative pressure source when the rotational speed of the exhaust turbo supercharger or the exhaust pressure of the engine exceeds a predetermined value. An exhaust gas recirculation control device for an internal combustion engine with a supercharger, characterized in that a means is provided.
