摘　　要：介绍了目前常用的排气热量测量方法,即直接测量法和间接测量法;通过测量WD615柴油机排气热量,对两种方法进行比较研究。试验结果表明,在试验条件有限时,采用直接测量法可以得到相对更好的结果。The main content of the experiment of engine heat balance is the measure of the exhaust gas heat. Because of the high temperature and complicated composition of the exhaust gas, it is difficult to get the thermal capacity of exhaust directly. The thermal capacity of exhaust can be got directly or indirectly. The exhaust gas of the WD615 has been investigated to provide reference for the comparison of such two measurements. The results show that when the condition of the experiments is confined, the direct measurement can result in better conclusion.
