ABSTRACT:
A steam enhanced dual piston cycle engine utilizes a unique dual piston apparatus that includes: a first cylinder housing a first piston therein, wherein the first piston performs only intake and compression strokes; a second cylinder housing an inner power piston that forms an inner internal chamber of the second cylinder, and either a ring-shaped outer power piston surrounding the inner power piston, wherein the outer power piston forms an outer internal chamber of the second cylinder and is configured to convert engine heat into additional work, and/or an outer boiler which is configured to produce steam to be converted into additional work.
