内燃机有限时间内不可逆循环热力学分析

本文讨论了内燃机循环在逐步考虑各种主要不可逆因素后所构成的一系列新的热力学模型下有限时间热力学分析，重点寻找出在规定的模型下其循环最大输出功率与对应的热效率之间的关系，给出了有限时间热力学意义下内燃机循环新的性能界限，它们对实际内燃机性能的评估及改进有一定的指导意义。

Finite Time Thermodynamic Analysis of Internal Combustion Engine Irreversible Cycle

In this paper, a series of thermodynamic modes which based on considering several principal irreversible factors are established, and then finite time thermodynamic problem of internal combustion engine cycle is studied. The relation between optimal thermal efficiency and maximum power output are presented emphatically, and some new finite time thermodynamic bounds of performance for internal combustion engine are induced from it. The formulae derived in this paper provide a useful guide to the achievable performance for internal combustion engine.
