Abstract
An internal combustion engine is coupled to a supercharger operable to supply varying amounts of air to the engine responsive to the load on the engine. The supercharger has a pair of screw rotors driven by the engine to move air to the engine and a control apparatus for varying the mass and pressure of air supplied to the engine.
