ス還流装置。In a spark-ignition internal combustion engine that uses alcohol as fuel, a recirculation passage that connects an intake passage and an exhaust passage and returns part of the exhaust gas to the intake passage; A diaphragm device having a diaphragm operatively connected to the valve body and a negative pressure chamber partitioned by the diaphragm, which connects the negative pressure chamber to a downstream side of the intake passage from the throttle valve. The valve body is characterized by comprising a negative pressure passage that communicates with the valve body, and a spring that biases the valve body in the opening direction, and the valve body is configured to close according to the magnitude of the negative pressure generated in the negative pressure chamber. Exhaust gas recirculation device.
