摘　　要：利用示功图来计算柴油机燃烧过程是研究和诊断柴油机燃烧过程的有效手段之一,而计算结果的准确度主要取决于示功图的测录与处理。本文介绍了两种示工图上止点修正方法,按照上止点修正理论编辑了上止点修正的程序块,并对四冲程柴油机实测倒拖示功图进行了上止点修正。结果发现,随着转速的升高,漏泄及传热损失减小,热力损失角也随之减小。One of the effective means to research and diagnose the combustion process of diesel engine is to use the indicator diagram to calculate it.The accuracy of the results depends on the testing and treatment of the indicator diagram.In the process of TDC correction,two TDC correction methods are introduced,and the program blocks according with the theory of TDC correction are edited.With the program,the TDC of four-stroke diesel engine is corrected.The results show that with increase of rotational speed,the leakage and heat loss and the heat loss angle decreased.
