Abstract
engine friction; vehicle fuel economy Abstract. The engine friction loss and vehicle fuel economy aiming at several kinds of energy-conserving engine oils with different quality standard, viscosity grade, friction modifier, and viscosity index improver were tested in this paper. Experimental results showed that the engine friction loss was reduced and vehicle fuel economy was improved by lowering the viscosity of engine oil and adding high-performance friction modifier and new-type viscosity index improver. Among which, the effect of energy-conser ving engine oils Dexos1 5W-20 adding 1% friction modifier and new type viscosity index improver was most significant with 12.45% engine friction reduction rate and 2.33% vehicle fuel economy improvement rate.
