【摘要】 为了考察汽油机油的燃油经济性,在不同试验条件下,用高频往复试验仪(HFRR)模拟发动机的工作状况测定汽油机油的摩擦因数。该模拟试验与发动机台架试验具有良好的一致性。摩擦因数越小,汽油机油的燃油经济性越好。模拟试验表明,添加0.5%有机钼摩擦改进剂的汽油机油的燃油经济性提高了0.4%。可根据该模拟试验筛选出燃油经济性较好的汽油机油配方。更多还原

【Abstract】 In order to investigate the fuel economy of gasoline engine oils,the frictional coefficients of gaso line engine oils were measured by high frequency reciprocating rig(HFRR) to simulate the working conditions of the engine under different test conditions.This simulation test had a good consistency with engine rig test.The smaller the frictional coefficient was,the better the fuel economy of the gasoline engine oil was.The simulation results demonstrated that the fuel economy of gasoline engine oil with 0.5% organic molybdenum frictional modifier was increased by 0.4%.The gasoline engine oils formulation with better fuel economy would might be screened out according to the simulation test.更多还原
