摘要: 参照GFC Lu-43-A-11方法,在ACEA C3 5W-30规格配方油品的基础上,研究了发动机油在含生物柴油条件下的抗氧化性能,系统考察了在生物柴油存在条件下润滑油抗氧剂、抗氧抗腐剂(ZDDP)、清净剂、分散剂等添加剂对发动机油抗氧化性能的影响。结果表明:在含生物柴油条件下,胺型抗氧剂、仲烷基ZDDP、高碱值清净剂、高分子丁二酰亚胺分散剂等添加剂对抑制发动机油的氧化衰变过程具有更好的效果。

Abstract: The simulated oxidation test method of engine oils blended with biodiesel was established referring to GFC Lu-43-A-11. Based on the oil formulation that fits the ACEA C3 5W-30 oil sequence, the influence of additives such as antioxidants, ZDDPs, detergents and dispersants, on anti-oxidation performance of engine oils containing biodiesel was studied. The results demonstrated that the additives such as amine antioxidants, secondary alkyl ZDDPs, high TBN detergents, high molecular weight succinimide dispersants showed better anti-oxidation performance of engine oils containing biodiesel.
