摘要： 为了进一步提高发动机热效率，需要对发动机动力循环中的能量利用做出分析，可用能分析可以从“质”的方面对发动机工作过程中的能量利用做出评价。该文利用发动机工作过程有限时间热力学模型，对发动机工作过程中的可用能损失进行了全面的分析，所得结论与发动机实际工作过程基本一致。

Abstract:

To further improve thermal efficiency of internal combustion engine, analysis of energy utilization in engine dynamical cycles is needed. Analysis of available energy can estimate the energy utilization in dynamical cycles of engine in terms of quality. Based on a model of finite time thermodynamics in the engine operation, loss of the available energy is analyzed. The results obtained are in good agreement with that in the actual engine operation.
