A compact supercharged internal combustion engine, wherein the supercharger is mounted above the twin overhead cam cylinder head of the engine but is readily detachable from it. The drive for the pumping elements of the supercharger including counter rotating shafts to which balance masses are added so as to assist in engine balancing. In addition to supplying compressed air to the combustion chambers of the engine for combustion, the supercharger also supplies air to an air injection system that cooperates with the exhaust system for reducing the emissions of undesirable pollutants to the atmosphere.
