Abstract
In an exhaust system for an internal combustion engine which is constructed such that when a degree of opening of a waste gate valve is equal to or larger than a predetermined degree of opening, the bypass exhaust gas flows so as to direct to a predetermined portion on the upstream side end face of the exhaust gas purification catalyst, and that the exhaust gas sensor is arranged in a specific passage, which is an exhaust passage between a turbine and the exhaust gas purification catalyst, the exhaust gas sensor is arranged to be away, a first distance or more in a direction orthogonal to an axial direction of the exhaust gas purification catalyst, from a region (scattering region B) in which the predetermined portion is virtually extended to a side of the specific passage along the axial direction of the exhaust gas purification catalyst.
