Abstract

See full text

In an exhaust gas purification apparatus for an internal combustion engine which is provided with a supercharger, an exhaust gas purification catalyst, a bypass passage, a wastegate valve, and a flow regulating member for changing a direction of flow of exhaust gas, the exhaust gas purification catalyst and the flow regulating member are arranged in such a manner that when warming up the exhaust gas purification catalyst, bypass exhaust gas goes toward an upstream side end face of the exhaust gas purification catalyst, whereas when the internal combustion engine is operated in a predetermined high load region, the bypass exhaust gas goes toward the flow regulating member. The flow regulating member includes a guide portion that guides the exhaust gas thus impinged in a circumferential direction of an exhaust pipe, and the guide portion is formed with a plurality of through holes.
