Claims

[Scope of utility model registration request]

An exhaust turbo supercharger driven by exhaust gas is provided in the intake system, and a spiral inlet passage for the exhaust gas to the exhaust turbine in the exhaust turbo supercharger is configured into a plurality of inlet passages. In an internal combustion engine in which at least one inlet passage is provided with a control valve that opens and closes the one inlet passage, the control valve is controlled at a rotational speed using two parameters: the rotational speed of the internal combustion engine and the load on the internal combustion engine. 1. An internal combustion engine with an exhaust turbo supercharger, characterized in that the engine is equipped with a control means configured to perform a closing operation when the rotation speed is below a certain set value and the load is below a certain set load.
