高档汽油机油高温高速行车试验

FIELD TEST OF PREMIUM GASOLINE ENGINE OILS IN HIGH TEMPERATURE AND HIGH SPEED CONDITIONS

本行车试验系用不同类型的专用试验车,在苛刻的高温、高速试验条件下,评价高档汽油机油(QF 和 QE 级)的抗氧化性和清净性,同时,为正在研究中的评定试验新方法确定试验条件和参考油样提供依据,进而确定与 MSⅢD试验结果的相关性。试验结果达到预期目的,是一次比较成功的行车试验。

Field tests have carried out with vehicles of different type on severe service conditions to assess the antioxidation and cleaniness performance of QF oil in compar- ison with QE oil.The feeld test were run in a specially constructed cycle-track with special cars.Oil drain and filter changes were maintained at 15000km or more than 25000km to pro- vide severe service conditions.Field test and used oils analyses demonstrated that QF oil pro- vided better performance than QE oil.
