Abstract:
A combustion engine includes a combustion chamber without pistons, wherein combusted and expanded air exiting the combustion chamber flows into a first displacement pump, such as a gear pump or radial vane pump. The displacement pump dnves the load, and, in addition, another smaller second displacement pump, which pressurizes fresh air and introduces same, via a feedback loop, into the combustion chamber. Gas or other burnable fuels are introduced in the combustion chamber, so that continuous fuel burning will occur, after being ignited. The ratio of bigger to the larger pump to the smaller pump is influenced by the percentage of expansion of the air in the combustion chamber. Additional embodiments could include spπng loaded adjustable baffles within the chamber, meandenng walls and protrusions in the feedback loop, and heating the air prior to entry into the feedback loop.

Abstract:
A method of performing work and an apparatus for performing the method utilizing the following thermodynamic cycle. Ambient air is isothermally compressed to a predetermined degree (A-B) and then heat is added to the air at constant pressure (B-C). This is followed by isentropic compression (C-D) which in turn is followed by heat addition at constant volume (D-E). Thereafter follows isentropic expansion (E-F-H-G) then finally heat recovery (G-A). The recovered heat (G-A) is preferably utilized for the initial heat addition (B-C).
