原报告提出一个适用于发动机冷起动和高增压发动机在超量供油时燃烧效率等广泛问题的工作理论,此理论建立了十六烷值和压缩冲程内的温度时间积分间的关系。而本文摘译了有关冷起动部分,它可提供柴油机在设计时,预定其低温状况下的起动性能,及分析研究低温起动时的一些影响因素。 The original report proposed a working theory applicable to a wide range of issues such as cold start-up of engines and combustion efficiency of supercharged engines with excess fuel supply. This theory established the relationship between the cetane number and the temperature-time integral in the compression stroke. In this paper, the cold starting part is extracted, which provides the starting performance of a diesel engine when it is designed and scheduled for its low temperature conditions, and analyzes some influencing factors when starting at a low temperature.
