弁を有する排気ガス再循環装置。 In an exhaust gas recirculation device for an internal combustion engine having an exhaust gas take-off port for exhaust gas recirculation in each of two exhaust passages, from each of the exhaust gas take-off ports provided in each of the two exhaust passages. The exhaust gas recirculation passage is provided in the middle of an exhaust gas recirculation passage that leads exhaust gas to the intake passage, and the exhaust gas from each of the exhaust gas extraction ports is arranged so that the flow rate of exhaust gas flowing from each of the exhaust gas extraction ports to the intake passage is equal to each other. An exhaust gas recirculation device comprising a balance valve that throttles and controls a flow rate of exhaust gas from the exhaust gas extraction port in response to a pressure difference between the exhaust gases.
