Abstract
An internal combustion engine and method is disclosed wherein separate compression and power cylinders are used and a regenerator or pair of regenerators is mounted between them to provide heat for hot-air ignition. The single regenerator embodiment operates as a two-stroke cycle engine and the embodiment with an alternating pair of regenerators operates as a four-stroke cycle engine. The engine varies the amount of air entering the power cylinder to control the engine output during naturally aspirated operation using valve timing and/or volume control of dead space and can optionally include supercharging to control the engine at higher output levels.
