諸機関のエネルギ変換効率の改善について : 名称および理論エネルギ変換効率について

Instead of the traditional thermal efficiency for engines, the better name should be adopted. And, the new improved energy conversion theory for engines is adopted instead of the traditional energy conversion theory of thermodynamics. The following three ideas are applied in the improved theory : (a) Energy (quantity) of each change should be calculated on the cycle-lowest base (atmospheric condition) in place of the absolute zero base; (b) The energy required for compression work in a cycle can not be ignored; and (c) The phenomena taking place in the combustion chamber are only one part in the engine, and the brake (net) performance should be obtained by considering the entire engine. As a result, the provisional-net energy conversion efficiency in the entire engine in place of the traditional theoretical thermal efficiency in the combustion chamber is obtained by the improved theory. And, the efficiency has related closely to the brake thermal efficiency, and more, the theoretical forecast of engines development has been improved
