考虑摩擦时Diesel循环功率效率特性新析

摘要

The Diesel engine cycles are investigated by finite time thermodynamics in this paper. The new relations between power and compression ratio, between efficiency and compression ratio are derived，by which the new relation curve is obtained. Finally, these relations are plotted and discussed. Comparing the results with the related results in published literature, some useful conclusions are drawn.%对有摩擦时Diesel循环进行了有限时间热力学分析.导出功率和压缩比、效率和压缩比的新关系式，进而得到功率效率关系，并进行了计算和讨论，给出一些有益的结论.
