給機付き内燃機関における排気ガス還流装置。In an internal combustion engine with a supercharger, the exhaust gas recirculation passage that connects the intake system and the exhaust system is divided by a diaphragm.
A recirculation control valve having two diaphragm chambers is provided, and one diaphragm chamber of the recirculation control valve controls the intake negative pressure at the throttle valve in the intake system, and when the intake negative pressure increases toward the vacuum side, the recirculation is controlled. In an exhaust gas recirculation device in which a valve portion of the valve is related to open an exhaust gas recirculation passage and introduces pressure on the upstream side of the throttle valve in the intake system into the other diaphragm chamber, the recirculation control valve includes a When the opening area of the exhaust gas recirculation passage becomes larger than a predetermined value due to the rise of the valve part, the exhaust gas recirculates.Exhaust gas in an internal combustion engine with a supercharger, characterized in that a sub-valve part is provided to reversely close two passages. Reflux device.
