作者根据自己的试验研究并综合已有的文献,在文中阐述了11种确定柴油机始燃点的方法和7种确定终燃点的方法,其中有多种是首次见诸文献的。文中还对确定始燃点的各种方法作了理论的和试验的比较,并对确定终燃点的复杂性作了分析讨论。文中给出了作者试验所得的多种图形。总之,本文是作者研究柴油机燃烧过程的系列论文之一,对研究柴油机燃烧的始、终点有参考价值。 Based on our own experimental research and synthesis of the existing literature, the author elaborates 11 methods for determining the ignition start point of diesel engines and seven methods for determining the ignition start point, many of which are for the first time documented. The paper also made a comparison of the theoretical and experimental methods for determining the initial ignition point, and analyzed the complexity of the final ignition point. The article gives a variety of graphics obtained by the author experiment. In short, this article is one of a series of papers that the author studied the combustion process of diesel engine, which is of reference value to the study of the beginning and end of diesel engine combustion.
