Abstract
A supercharger control system for an internal combustion engine equipped with a supercharger to be driven by output torque of the engine and including an electrically operated clutch for transmitting the output torque of the engine to the supercharger upon engagement thereof and for disconnecting the supercharger from the engine upon deenergization thereof. The control system comprises a bypass air duct bypassing the supercharger to provide a bypass air flow routed into the intake manifold of the engine, an electrically operated valve disposed within the bypass air duct to be open during deactivated condition of the supercharger and to be closed in response to activation of the supercharger, and an electric control device for engaging the clutch and closing the valve when high engine output torque is demanded and for disengaging the clutch and opening the valve when low engine output torque is demanded.
