本文针对几台不同类型柴油机进行了热负荷规律性的研究.对受热零件采用不同的方法进行了温度测量,分析了主要结构因素和运转因素对受热零件的影响.对活塞平均热流量和缸盖局部热流量进行计算,得到高增压予燃式柴油机q∞(G_T)~(0.89)的结果和计算局部热流量的系数值.为评定柴油机受热零件的热状态、热流的分配、受热零部件改进时控制热负荷提供了一些依据.
In this paper, several different types of diesel engine heat load regularity.Heat heating parts using different methods for temperature measurement, analysis of the main structural factors and operating factors on the hot parts.Analysis of the piston average heat flux and cylinder head The local heat flux is calculated and the result of q ∞ (G_T) ~ (0.89) and the coefficient value of local heat flux of the supercharged pre-ignition diesel engine are obtained.For the purpose of assessing the thermal status and heat flow distribution of the heated parts of diesel engine, Improve the control of heat load provides some basis.
