Energy transformation method and its system for piston reciprocating cycle

摘要

An energy transformation method and a system for carrying out this method which are capable of improving the energy transformation efficiency upon transforming the thermal energy to kinetic rotating energy, and improving the thermal efficiency, while at the same time reducing environmental pollution by purifying the exhaust gas and/or enhancing unit power, whatever the number of cycles or the type of ignition. The present energy transformation method and the system for carrying out this method can change the non-constant volume combustion of the prior art, which is caused by the rapid increase in the combustion chamber volume due to the downward movement of the piston immediately after the piston passes through TDC, to a substantially constant volume combustion which is attained by isolating substantially the combustion chamber through TDC, whereby the combustion pressure can keep on increasing until the completion of such substantially constant volume combustion. As a result, maximum combustion pressure occurs when the piston passes through TDC.
