Heat transfer effects of the net work output and efficiency characteristics for an air- standard Otto cycle

摘要

Finite-time thermodynamic analysis of an air-standard Otto cycle is performed in this paper. The relation between net work output and efficiency of the cycle is derived. The maximum net work Output and the corresponding efficiency bound of the cycle with heat transfer considerations are also Found. Detailed numerical examples are given. the result obtained herein provide a guide to the per- Formance evaluation and improvement for practical Otto engines.
