Lubricant oil composition for diesel engines (LAW964) |
摘要 |
The present invention provides a lubricant oil composition, having enhanced wear-preventive characteristics for a diesel engine operating with large quantities of soot in the oil (soot content: 0.2 to 4.0 wt. %), and is especially suitable for a pressure-accumulating (common rail) type diesel engine equipped with an EGR system. The lubricant oil composition containing a base oil composed of a mineral and/or synthetic oil incorporated with at least three additives that are a sulfurized oxymolybdenum dithiocarbamate at 0.03 to 0.50 wt. % as Mo; a zinc dialkyl dithiophosphate at 0.04 to 0.50 wt. % as P; and at least one metallic salt of alkyl salicylate selected from the group consisting of a Ca salt of alkyl salicylate at 0.004 to 1.0 wt. % as Ca, Mg salt of alkyl salicylate at 0.002 to 0.60 wt. % as Mg, and Zn salt of alkyl salicylate at 0.006 to 1.60 wt. % as Zn, all percentages being based on the whole composition.
