As a result, it became clear that the theoretical thermal efficiency of the constant-volume cycle was higher than the constant-pressure cycle, when the compression ratio was lower and the air-fuel ratio was richer.It was suggested that the new heat engine which could be operated in high-speed having the theoretical thermal efficiency was equal to the conventional diesel engine.}, pages = {31--34}, title = {同一圧縮比の定容/定圧サイクルの理論熱効率に関する考察}, volume = {4}, year = {2010}, yomi = {イトウ, ヒロカズ and ヤマダ, ヒロカズ and ホンモウ, ユキオ} }
