摘　　要：用倒拖法对6110型直喷柴油机整机及各零部件的机械损失进行测量,提出了发动机的整机机械损失功率比和零部件机械损失功率比评价指标。分析了发动机各零部件和整机的机械损失功率比、机械损失功率、机械效率和平均机械损失压力随发动机转速和润滑油温度变化的规律。实验结果表明,发动机机械损失功率比和其他评价指标一样,不仅可以评价整机的机械损失的大小,也可以评价各零部件的机械损失大小。The mechanical loss of 6110 Diesel engine has been measured by dynamic test branch. The concepts such as the ratio of mechanical power loss and the ratio of mechanical power loss of component were put forward. The regulation of mechanical power loss, the ratio of mechanical power loss,mechanical efficiency, mean mechanical effective pressure, the ratio of mechanical loss varying with the rotation and the temperature of coolant were analyzed. Results show that the new concepts are same like the other evaluating index. It can evaluate the mechanical loss of the engine and the parts of the engine.
