Title: HEAT ENGINE
Abstract:
A heat engine comprising compressor and expander displacement elements (210, 211) reciprocating in respective compression and expansion chambers (111, 111', 102, 102' ) and arranged in a linear, free-piston configuration, a combustor (116) separate from the compression and expansion chambers (111, 111', 102, 102' ), and a linear energy conversion device (212, 213) providing conversion of solid, liquid, or gaseous fuel into hydraulic, electric, or pneumatic energy by means of subjecting a working fluid to a thermodynamic cycle with substantially constant pressure combustion. The inlet and outlet valves of the compression chamber (102, 102' ) and the rate of fuel injection to the combustor (116) are actively controlled by an electronic controller to avoid engine damage, and to maintain thermodynamic efficiency over a wide range of loads.
