Finite-time thermodynamic performance of a Dual cycle

Finite-time thermodynamic analysis of an air-standard internal-combustion D ual 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 limit of the cycle with heat transfer considerati ons are also found. Detailed numerical examples are given. The results obta ined herein provide a guidance to the performance evaluation and improvemen t for practical internal combustion engines. Copyright (C) 1999 John Wiley & Sons, Ltd.
