摘　　要：采用全球统一轻型车辆测试循环(World Light Vehicle Test Cycle, WLTC)循环工况,在2款具有代表性的国Ⅵb汽油发动机台架上分别从基础油、黏度指数改进剂、抗氧剂3方面考察润滑油对排放颗粒物数量(Particle Numbers, PN)和排放颗粒物质量(Particulate Matter, PM)的影响。考察结果表明,参比油和8个试验油的排放颗粒物指标均可满足国Ⅵb排放法规要求。在润滑油配方中通过使用高比例链烷烃、低挥发性的基础油,优化黏度指数改进剂类型,以及补加耐高温抗氧剂等方式,可以协助发动机进一步降低颗粒物排放水平。Using the WLTC(World Light Vehicle Test Cycle)cycle condition,the impact of lubricating oils on the PN(Parti-cle Numbers)and PM(Particulate Matter)were investigated from the aspects of base oil,viscosity index improver and an-tioxidant on two representative China VIb gasoline engine benches.The results show that the particulate matter emission in-dicators of the reference oil and the eight test oils can meet the requirements of China Vb emission regulations.In the for-mula of lubricating oils,it can help to further reduce the particulate matter emissions from engines by using low-volatile base oils with a high proportion of paraffin,optimizing the viscosity index improver types,and adding high-temperature an-tioxidants.
