Abstract

PURPOSE:To obtain smooth travelling in usual driving and excellent accelerationability in acceleration compatibly by using a mechanical supercharger in a broad speed range at the time of acceleration in a substance driving an exhaust turbosupercharger in a high speed range and a mechanical supercharger in a low speed range respectively. CONSTITUTION:The blower 16s of an exhaust turbosupercharger 16 is provided to supercharge suction gas to the common suction gas passage 12 in the course lower than an airflow meter 15 in the given high speed range. And the blower 16s is driven by the rotation of a turbine 16t caused by exhaust gas. And a Roots-type mechanical supercharger 22 for supercharging exhaust gas in the given low speed range is provided in the course of the common suction gas passage 12 lower than the blower 16s and driven by the pulley 26 provided to a crank shaft 25. In this case, when an engine is detected to be in the given acceleration state in a control circuit 43 in which the output of various sensors detecting engine revolution, throttle opening and so on is input, the speed range in which the mechanical supercharger is used is expanded to increase supercharging pressure.
