Abstract
A mechanical supercharger is operatively connected to the engine output shaft when the engine speed is not lower than a predetermined engine speed and disconnected from the engine output shaft when the engine speed is lower than the predetermined engine speed. The engine load is detected and the predetermined engine speed is set lower as the engine load becomes lighter.
