摘　　要：综合对比了柴油机油我国自主D1规格和API CK-4规格在理化性能指标、发动机台架试验性能指标等方面的差异;进而,结合中国石化自主开发的符合API CK-4规格的柴油机油复合剂技术(RIPP C0010)在两种规格发动机台架试验中的评价结果,系统分析D1规格与API CK-4规格的相关性,以及RIPP C0010柴油机油技术对国产发动机的适用性。结果表明:除柴油喷嘴剪切后高温高剪切黏度存在差异外,D1规格与API CK-4规格的其他理化性能指标,包括高低温运动黏度、蒸发损失率、高温抗腐蚀性、抗泡性能、元素含量等均基本相同;D1规格的4种台架试验均可以评价多项油品性能,如抗氧化性能、清净性能、分散性能、抗磨性能等,实现了API CK-4规格10种台架试验的评价效果,但仍需进一步完善其基础油互换规则和黏度级别延伸规则;行车试验结果表明,自主研发RIPP C0010柴油机油可满足重载柴油发动机60000 km换油周期使用要求。The differences in physicochemical properties and engine test performance between D1 and API CK-4 specification were compared.Furthermore,the correlation between D1 and API CK-4 specification,the applicability of RIPP C0010 diesel engine oil package technology to domestic engines were systematically analyzed based on the evaluation results of the engine tests.The results show that except for high temperature and high shear viscosity after shearing,D1 and API CK-4 specification have same physical and chemical indexes.The 4 engine tests of D1 specification can evaluate the engine oil properties,such as antioxidation,cleaning,dispersion,anti-wear performance,and so on,achieving the evaluation effect of 10 engine tests of API CK-4 specification,but it is still necessary to further improve its base oil exchange guideline and viscosity grade extension guideline.The driving test results show that RIPP C0010 diesel engine oil can meet the requirements of 60000 km oil-change cycle for heavy-duty diesel engines.
