A model of endoreversible Otto cycle is established in this paper. And we make optimization for the model,and arrive at the maximun power output and the efficiency at maximun power output. It is based on the endoreversible Otto cycle that frictionally irreversible Otto cycle is proposed. Under the condition of Q1/CuTH ( 1- e- 1t1 )≤1, we acquire optimal performance of the frictionally irreversible Otto cycle. In the end ,we further discuss what we have gained.

The performance of an air-standard Otto cycle with heat transfer loss and variable specific heats of working fluid is analyzed by using finite-time thermodynamics. The relations between the power output and the compression ratio, between the thermal efficiency and the compression ratio, and the optimal relation between work output and the efficiency of the cycle are derived by detailed numerical examples. Moreover, the effects of heat transfer loss and variable specific heats of working fluid on the cycle performance are analyzed. The results show that the effects of heat transfer loss and variable specific heats of working fluid on the cycle performance are obvious, and they should be considered in practice cycle analysis. The results obtained in this paper may provide guidance for the design of practice internal combustion engines.
