Compound engine

Compound Engine Development and the novel method of cylinder filling, piston stop study, dual heat path, piston cooling, combustion chamber pressure development in the constant volume phase, stress containment in the non moving piston, emissions with the direct injection installation. This development’s intention is to answer the question of alternate method of production of mechanical power from the expanding medium. The field of interest is dominated exclusively by the conventional Four Stroke, conventional Two Stroke and to smaller degree the Wankel engine with the first two existing in both low compression and Diesel configuration engine and Wankel as low compression only. Those engines are present throughout the broad range of commercial applications since the since the turn of the 20 th century. The Compound Engine Development and Compound Engine patents address the means and methods of exchange of spent or burned gasses for the fresh charge of air or fuel–air mixture in the two stroke configuration using the circular cross section pistons like the conventional Four and Two Stroke engines mentioned above and the practical method of stopping the piston mid cycle that will create a constant volume combustion chamber for the duration of the combustion process.
