    Abstract: The disclosure describes a drive system including an engine with a rotor which has oscillatory motion. The engine may be of either an internal or external combustion type. The drive system further includes a conversion device coupled to the engine rotor and adapted to convert the oscillatory motion of the engine rotor to unidirectional energy. The power output of the system may be controlled by controlling the speed and length of stroke of the engine.
