SE和SF汽油机油程序Ⅲ试验国产化研究

STUDY ON THE CHINESE ENGINE PROCEDURE TEST (CEPT-Ⅲ) FOR EVALUATING SE AND SF CATEGORY GASOLINE ENGINE OILS

用国产发动机评价SE、SF汽油机油高温氧化性能台架试验的研究 ,参考美国程序ⅢD试验方法 ,建立了国产的程序Ⅲ (CEPT -Ⅲ )试验方法 ,结果表明 :CEPT

The Chinese Engine Procedure Test Ⅲ (CEPT-Ⅲ) is set up by using engines made in China to evaluate the high-temperature oxidation properties of SE and SF category gasoline engine oils with reference to Sequence ⅢD. The results show that the CEPT-Ⅲ has good discriminability and repeatability and the severity is corresponding to Sequence ⅢD.
