摘　　要：将环烷基基础油KN4006和KN4010作为基础油组分的一部分应用到CD柴油机油中,通过理化性能的考察,确定在不同黏度级别CD柴油机油中环烷基基础油的最大加量。Caterpillar 1G2和CRC L-38发动机台架试验结果表明,以KN4006环烷基基础油为部分基础油组分调制的CD 15W-40柴油机油满足GB 11122-2006质量指标的要求;环烷基基础油KN4006和KN4010调制的CD柴油机油储存稳定性良好,常温和高温储存稳定性考察均无沉淀出现。Naphthenic base oils KN4006 and KN4010 as part of the base oil components were applied in CD diesel en- gine oil. The maximum dosage naphthenic base oil in CD diesel engine oil of different viscosity grades of base oil was deter- mined through the analysis of the physical and chemical properties. The experimental results of Caterpillar 1 G2 and CRC L- 38 engine bench test show that the CD 15W-40 diesel engine oil modulated using naphthenie base oil KN4006 as part of the base oil can meet the quality index requirement of GB 11122-2006. The CD diesel engine oils modulated with naph- thenic base oils KN4006 and KN4010 have good storage stability,which have no precipitation under normal and high tem- perature storage stability test.
