摘要： A supercharger includes a turbine housing (15) and a pipe. An exhaust-gas inlet portion (17) of the turbine housing (15) is connected to an exhaust system member, and includes a scroll port (27) and a bypass port (28). The pipe is configured to cover an inner peripheral surface of the exhaust-gas inlet portion (17) in a state where at least part of the pipe is distanced from the inner peripheral surface, and includes an inserted portion which is positioned in the exhaust-gas inlet portion (17) of the turbine housing (15). An inner passage of the pipe is branched into a first branch passage (34) connected to the scroll port (27) and a second branch passage (35) connected to the bypass port (35). At least part of a pipe wall of the pipe is a part of the second branch passage (35), and is distanced from the inner peripheral surface of the exhaust-gas inlet portion (17).

摘要： The minimum value for the degree of opening of a wastegate valve (24), wherein the flow volume of exhaust air flowing via a wastegate port (22) when the degree of opening of the wastegate valve (24) is changed toward the open side stops increasing, is defined as a first prescribed degree of opening. An electronic control device (50) controls the degree of opening of the wastegate valve (24) on the basis of the engine operating state, and when the vehicle is running steadily at a high speed, that is, when the degree of opening of the wastegate valve (24) which has been set on the basis of the engine operating state is equal to or greater than the first prescribed degree of opening, the degree of opening of the wastegate valve (24) is varied between values equal to or greater than the first prescribed degree of opening.
