    摘要：本文为了解决喷油器故障率高的问题而研究柴油润滑性,这是因为喷油器是由柴油进行润滑的。试验采用SRV4摩擦磨损试验机,对试验室在用的国Ⅲ、国Ⅳ的柴油进行润滑性试验,试验结果表明两种柴油都符合标准,国Ⅲ的柴油磨斑是国Ⅳ柴油的两倍。

    Abstract: The paper is focused on solving the problem of the fuel injector due to lubricating characteristic of diesel fuel.In this test,fuel lubricating characteristic test is done on GB III and GBⅣ using SRV4 test instrument.The test results indicate that two kinds of fuels meet the standards but the wear with GB III fuel is two times higher than that of GB Ⅳ fuel.
