摘　　要：为了探究机油在不同温度下,粘度的改变对发动机油耗方面的影响,基于AVL 250KW电力测功机,软件控制系统为PUMA1.5.3,油耗测量采用AVL740,采用一台增压汽油发动机和一台自然吸气汽油发动机作为研究对象,在调节不同温度机油温度情况下,对发动机额定功率、进行油耗性能及排放的比较,从而探究机油温度对发动机油耗的影响。In order to investigate the impact of viscosity changes on engine oil consumption at different temperatures,based on an AVL 250KW electric dynamometer with PUMA1.5.3 software control system and AVL740 fuel consumption measurement,a turbocharged gasoline engine and a naturally aspirated gasoline engine were used as research objects.The rated power,fuel consumption performance,and emissions of the engine were compared by adjusting the oil temperature at different temperatures,To explore the impact of engine oil temperature on engine fuel consumption.

关 键 词：机油温度 汽油发动机 油耗 粘度
