Abstract
An improved accessory drive which employs the crankshaft and camshaft of an internal combustion engine to operate, at different times, the accessory drive system for the engine; the camshaft rotating at exactly 50% of the speed of the crankshaft. A clutching system disconnects the crankshaft from the accessory drive system at a predetermined speed of rotation to allow the slower camshaft to assume activation of the accessory drive system.
