本文论述了燃速预测的重要性,分析了发动机中实际燃速与预测燃速的差异,分别评述了SPP程序对燃速的处理方法、标准发动机预测燃速的要求、测试精度对燃速相关性的影响以及用燃烧理论模型进行燃速相关的问题.介绍了端面燃烧药的锥化现象和内孔燃烧药柱的驼峰效应.最后对开展燃速预测的研究工作提出了建议.
This paper discusses the importance of fuel burn prediction, analyzes the difference between the actual burning rate and the predicted burning rate in the engine, reviews the processing method of the burning rate by the SPP program, the predicted burning rate of the standard engine, the correlation between the testing accuracy and the burning rate The influence of the combustion theory model and the burning rate, the tapering phenomenon of the end combustion agents and the hump effect of the inner combustion particles are introduced.Finally, some suggestions are put forward for the research on the combustion rate prediction.
