摘　　要：本文通过对ＪＢ３７４３－８４《汽车发动机性能试验方法》中柴油机功率校正公式的研究，在增压柴油机及增压中冷柴油机的试验基础上，阐述了发动机进气温度、进气压力对发动机功率的影响，并通过大量计算及分析，提出了对校正公式中某些参数的修改意见及讨论了不同进气温度、压力范围对发动机功率校正结果的影响，以提高增压柴油机功率校正的精度。Through the study on diesel engine power correctinn formula in the standard of JB3743-84 《Automobile Engine Performance Test Procedure》, a series of tests are taken to show the effect of inlet air temperature and pressure on engine power based on a turbocharged diesel engine and a turbocharged aftercooled diesel engine. Furthermore, in order to improve the accuracy of diesel engine power correction it is given some proposals to revise several parameters in the correction formula of JB3743-84, and also presented that the effect of different level of inlet air temperature and pressure range on the result of power correction with a large amount of calculations and analyses.
