Abstract
A heat engine comprising compressor and expander displacement elements () reciprocating in respective compression and expansion chambers () and arranged in a linear, free piston configuration, a combustor () separate from the compression and expansion chambers (), and a linear energy conversion device () 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 () and the rate of fuel injection to the combustor () are actively controlled by an electronic controller to avoid engine damage, and to maintain thermodynamic efficiency over a wide range of loads.
