Abstract
An internal combustion engine with a turbocharger includes a catalyst, downstream of a turbine, in an exhaust passage. The internal combustion engine includes a waste gate, and a waste gate valve. The internal combustion engine further includes a flow-adjusting member or a flow-adjusting mechanism. The flow-adjusting member disperses a flow of exhaust gas from the waste gate when the opening degree of the waste gate valve is small and concentrates the flow when the opening degree of the waste gate valve is large. The flow-adjusting mechanism switches between a dispersed state in which the flow is dispersed and a concentrate state in which the flow is concentrated.
