苛刻条件下含粘度指数改进剂油品的润滑特性研究

Study on the Lubricating Property of the Oil Blended with VI Improver under Harsh Terms

用四球机考察了含粘度指数改进剂的油品在苛刻条件下的润滑特性,证明其影响与正常润滑条件下的结论有差异。

The lubricating property of the oil blended with VI improver is studied with a four-ball tester under harsh terms, it is proved that the influence of VI improver on lubricant under harsh terms is different from that of normal condition.
