CK-4 15W-40柴油机油在烟台公交车辆上的应用简述

Application of CK-4 15W-40 Diesel Engine Oil in Yantai Public Transport

为适应新的环保要求,新的更高规格的CK-4应运而生,文章主要讲述CK-415W-40柴油机油在公交车上6×10^4km行车试验中的衰变情况。在试验周期内,试验机油表现出优异的黏度保持能力、抗氧化衰变能力、清净分散性和极压抗磨性,是CI-4、CJ-4升级换代产品,满足国Ⅵ排放标准,可进一步延长柴油机换油周期,帮助发动机制造商满足更加严格的排放要求。

In order to meet the new environmental requirements,the CK-4 diesel engine oil with new higher specifications came into being.This paper mainly describes the decay of CK-4 15 W-40 diesel engine oil in 60,000 kilometers driving test on buses.During the test period,the test oil shows excellent viscosity retention,anti-oxidative decay,detergency and dispersibility,extreme pressure and anti-wear properties.It is an upgraded product of CI-4 and CJ-4,which meets the national Ⅵ emission standard.It can further extend the oil exchange period of diesel engine and help engine manufacturers meet more stringent emission requirements.
