Abstract
A supercharger control system for an internal combustion engine wherein a control valve is advantageously placed in the inlet bypass of the supercharger. The control valve is activated and controlled by a combination of the throttle position and the pressure differential within the intake manifold. A linkage including a lost-motion mechanism connects the control valve to the engine throttle valve for limiting the closing of the control valve for supercharging to corresponding open positions of the throttle valve. A pressure differential device urges the control valve toward a closed position for supercharging upon the occurrence of a lower pressure at a venturi portion of the air intake than at a portion upstream thereof at the supercharger outlet.
