摘　　要：本文根据热平衡实验结果及有关过程参数对一定压加热循环内燃机热力过程进行了火用分析。从分析结果可以看出 :两种平衡分析所得出的总装置效率基本相同 ,但各种损失对装置效率的影响程度却有着很大的不同。火用平衡分析结果可以更具体的指出造成内燃机中可用能损失的原因及其影响程度并指明改进方向。本文的火用平衡分析结果表明 :减少排气冷却散热损失。In this paper,the exergy analysis of a constant pressure heating internal combustion engine is carried out on the basis of results of the heat balance test The results show that the values of efficiency of engine derived from heat balance and exergy balance analysis are approximately same but the degree to which every loss affects the efficiency of engine is apparently different Exergy balance analysis can more definitely point out the reasons causing available energy loss and the degrees to which they affect the efficiency of the engine The results of the exergy analysis in this paper show that decreasing the loss of the exhaust gas and cooling system and improving the combustion process are the main methods to increase the efficiency of internal combustion engine
