ABSTRACT:
An internal combustion engine provided with a mechanically operated supercharger in kinematic connection with a crankshaft the engine. The engine is provided with a system for controlling the effect of supercharging, such as a by-pass control valve. A timer is provided for detecting a predetermined short period after the engine is switched to an acceleration condition from the preceding deceleration condition with a fuel-cut, or after a moderate acceleration has begun. The system for controlling the effect of the supercharging is so controlled that the effect of supercharging is weakened during that period.
