Exhaust gas recirculation system for an internal combustion engine
An exhaust gas recirculation system for an internal combustion engine is disclosed that has an exhaust gas recirculation control valve of the diaphragm type which controls the opening of an exhaust gas recirculation passage and is actuated by intake vacuum of the engine modified by a vacuum control valve which in turn is actuated by the pressure of exhaust gases in the exhaust gas recirculation passage controlled by the exhaust gas recirculation control valve, the system further including a relief valve which opens a diaphragm chamber of the exhaust gas recirculation control valve to the atmosphere when the engine is decelerated so that the exhaust gas recirculation control valve immediately closes the exhaust gas recirculation passage when the engine is decelerated.
