Abstract
An exhaust system includes an electronic control unit that is configured to control a turbo bypass valve to be in a fully closed state and control an opening degree of a wastegate valve to a first predetermined opening degree during execution of fuel cut control, and maintain the turbo bypass valve in the fully closed state and control an opening degree of the wastegate valve to a second predetermined opening degree when a boost request is not made for the internal combustion engine at the end of the fuel cut control. An area of inflow of bypass gas on an upstream side end surface of the three-way catalyst when the opening degree of the wastegate valve is controlled to the first predetermined opening degree is in a different position from when the opening degree of the wastegate valve is controlled to the second predetermined opening degree.
