Provisional-net energy-conversion efficiencies of Otto cycle: comparison of theoretical and provisional-net energy-conversion efficiency of each 4 kinds

摘要

In the Otto cycle, the difference is made to be the provisional-net work from serving the compression work in next cycle from theoretical work. As an energy-conversion efficiency [EC Effi.] from it, the provisional-net [P-Net] EC Effi. isobtained. That is to say, 4 kinds of P-Net EC Effi. are obtained from 4 kinds of theoretical EC Effi. They are "the absolute zero (0)-base P-Net thermal Effi. (η{sub}(thae))", "the cycle lowest state (A)-base P-Net thermal Effi. (η{sub}(thbe))", "theabsolute zero (0)-base P-Net energy Effi. (η{sub}(ENce))" and "the cycle lowest state (A)-base P-Net energy Effi. (η{sub}(ENde))". As a result, it is shown that the provisional-net efficiency clarifies more EC Effi. from the theoretical to the net.
