置。 A surge tank is formed by an intake outlet communicating with an intake passage provided independently in each cylinder from upstream to downstream of the intake inlet, one end of which is connected to the surge tank, and the other end of which is an exhaust port. In an exhaust gas recirculation system for a multi-cylinder engine, which is equipped with an exhaust gas recirculation passage that opens into the system and recirculates part of the exhaust gas to the intake system, the opening of the exhaust gas recirculation passage in the surge tank is located upstream of the flow of intake air. A plurality of holes are sequentially formed from the opening toward the downstream side of the surge tank, and the amount of exhaust gas recirculated from the opening located on the upstream side of the surge tank is larger than the amount of exhaust gas recirculated from the opening located on the downstream side of the surge tank. Exhaust gas recirculation device for multi-cylinder engines featuring:
