摘　　要：重负荷柴油机要求其润滑油具备较好的高温抗氧化性能,欧洲汽车制造协会(ACEA)要求采用CEC-L-85-T-99高压差示扫描量热法(PDSC)来评价重负荷柴油机油的抗氧化性能。PDSC是一种有效评价内燃机油抗氧化性能的模拟试验方法,文章通过对不同规格重负荷柴油机油氧化诱导期的重复性和再现性考察,建立了一种新型的模拟评价重负荷柴油机油氧化性能的试验方法。Heavy-duty diesel engines require good high-temperature oxidation resistance of their lubricating oils.According to the European Automobile Manufacturers'Association(ACEA),CEC-L-85-T-99 Pressurized Differential Scanning Calo-rimetry(PDSC)should be used to evaluate the oxidation resistance of heavy-duty diesel engine oils.PDSC is an effective simulation test method for evaluating the oxidation resistance of internal combustion engine oils.The paper establishes a new simulation test method to evaluate the oxidation resistance of heavy-duty diesel engine oils by conducting repeatability and reproducibility investigation to heavy-duty diesel engine oil of different specifications at the oxidation induction period.
