The traditional theoretical thermal efficiency [ηth] of any energy power cycle has not been appropriate. And then, three new ideas have been adopted; (1) the basic available energy quantity, (2) not heat supplied but total energy supplied and (3) the energy flow including energy for compression work in a whole engine. The new energy conversion theory is termed “the improved energy conversion theory” and the new theoretical energy conversion efficiency is termed “the cycle lowest state base [A-base] energy (conversion) efficiency [ηENd]”. And, the provisional-net energy conversion efficiency [ηPNd] has been obtained from it and it has shown the theoretical prediction of the engine performance.
