Abstract
A single-cylinder, dual head internal combustion engine wherein in a single, mechanically unconstrained piston moves reciprocally within the cylinder between the two heads. Magnets or nonmagnetized ferromagnetic structures in the piston interact with magnets in a sleeve riding on the outside surface of the cylinder to cause synchronous movement of the sleeve. A yoke coupled to the sleeve may be coupled to a conventional crankshaft to convert the reciprocal movement of the sleeve into rotary motion. Multiple single-cylinder, dual head units may be ganged to form multi-cylinder engine configurations. In one embodiment, the magnets in the sleeve are electromagnets whereby de-energizing the electromagnets decouples the sleeve from the piston, thereby eliminating the need for a mechanical clutch in a power train driven by the engine.
