A lubricating oil composition comprising a base oil, (A) at least one compound selected from the group consisting of molybdenum dithiocarbamate and molybdenum dithiophosphate, and (B) an aromatic compound having at least one functional group selected from the group consisting of hydroxyl group, carboxyl group, mercapto group, and thiocarboxyl group on the aromatic ring.
The lubricating oil composition maintains the low friction property to achieve sustained low fuel consumption during the use and also enables using the organic molybdenum compound added as the friction modifier in a smaller amount than the amount required in conventional lubricating oil compositions.
一种润滑油组合物,包括基础油、(A) 至少一种选自由二
硫代
氨基甲酸钼和
二硫代磷酸钼组成的组的化合物,以及(B) 芳环上具有至少一个选自由羟基、羧基、巯基和
硫代羧基组成的组的官能团的芳香族化合物。
这种润滑油组合物能保持低摩擦特性,从而在使用过程中实现持续的低油耗,而且与传统润滑油组合物相比,有机
钼化合物作为摩擦改进剂的用量更少。
