人们总是希望修复后的柴油机能恢复到或接近于原来的标定功率。但对某些机型来讲,真正做到这一点并不是一件容易的事。为此,本文从理论分析入手,找出影响柴油机功率的诸项因素,分析在修理中未能达到预定的调整值的原因,为今后的修理实践提供理论依据。柴油机功率影响因素的定性表达式发动机动力性和经济性的好坏,可通过一些性能指标进行评价。对于结构已确定的发动机来讲,有的参数可作为常数处理。柴油机功率影响因素的定 People always hope that the repaired diesel engine can recover to or close to the original calibrated power. But for some models, this is not really an easy task. Therefore, this article starts from the theoretical analysis, finds out the factors that affect the power of the diesel engine, analyzes the reasons that the predetermined adjustment value can not be reached in the repair, and provides the theoretical basis for the future repair practice. Qualitative expression of diesel engine power factors Engine power and economic performance can be evaluated by a number of performance indicators. Some parameters can be treated as constants for engines with a defined structure. Diesel engine power factors
