ABSTRACT:
A by-pass control system for an internal combustion engine provided with a mechanical supercharger arranged in an intake pipe of the engine. The supercharger is connected to a crankshaft by means of a clutch operated in accordance with the engine load as well as the engine speed. A by-pass is arranged so as to by-pass the supercharger, on which by-pass a by-pass control valve is arranged. The by-pass control valve is operated in accordance with the engine speed, so that it is opened during an engine low load and high speed condition. The supercharger is located downstream of the throttle valve, while the by-pass is, on its downstream end, connected to the intake pipe downstream of the throttle valve and upstream of the supercharger.
