A multi-cylinder Stirling engine comprises a stationary casing, working fluid, at least one heat source, a first heat exchanger for carrying the working fluid and for transferring heat from the heat source to the working fluid thereby raising the working fluid's temperature, and an output shaft rotatably supported by the stationary casing, which provides reaction surface members in at least one chamber where the working fluid is allowed to expand as the reaction members are allowed to move with respect to the casing. A bi-directional flow regenerator with two chambers, a second heat exchanger for further lowering the temperature of the working fluid to a predetermined temperature, and a compression device for returning the relatively cool and therefore dense working fluid back into the first heat exchanger at a lower expense of work are provided. The casing output shaft with reaction members, expansion chamber and compression device have a rotary engine configuration. This engine configuration operably providing eight power strokes per revolution, thereby greatly increasing the power output of the engine over conventional Stirling engines.
