Definitions

  • the present invention relates to a novel lubricant composition. More specifically, it relates to a lubricant composition having good low abrasion and friction properties and being capable of sustaining low friction over a long period of time with no deterioration even in an atmosphere containing gaseous nitrogen oxides.
  • the lubricant composition can be used in internal combustion engine crankcases, automatic transmissions, wet brakes and power steering. Preferably it is used in crankcases of internal combustion engines.
  • Lubricants have been used to lubricate internal combustion engines, driving systems such as automatic transmission, wet brakes and power steering, and gears.
  • Lubricants for internal combustion engines in particular have as their primary function lubricating various sliding parts such as piston rings and cylinder liners, crankshaft bearings and connecting rod, and valve operating parts. Beyond this primary function crankcase lubricants also serve to cool the inside of engines, to clean engine parts, to disperse combustion products, and further to prevent rust and corrosion.
  • lubricants are blended with various additives, for example, wear preventing agents, metal salts of organic acids commonly known as detergents, ashless dispersants, and antioxidants.
  • Engine lubricating parts are mostly in a state of fluid lubrication, but vertical dead centers of valve operating systems and pistons are likely in a state of interface (or boundary) lubrication. In such a state of interface lubrication, wear preventing properties are generally provided by adding zinc dithiophosphate.
  • Friction modifiers are also added to the lubricants as a countermeasure to decrease efficiency loss from friction and thereby reduce fuel consumption.
  • friction modifiers for example, organic molybdenum compounds, fatty acid esters, alkylamines and the like, are used in general.
  • a lubricant has been discovered that has good lubricity and resistance to deterioration in the presence of oxygen and gaseous nitrogen oxides. It comprises a major amount of a lubricant base oil, a basestock of lubricating viscosity, to which a minor amount of additives has been added.
  • the additives comprise specific amounts of oxymolybdenum dithiocarbamate sulfide having specific alkyl groups, zinc dialkyldithiophosphate having specific alkyl groups, one or more specific sulfur containing compounds, an ashless dispersant and a boron containing additive which may be the ashless dispersant.
  • a metal detergent is used. Conveniently, the dispersant and boron are added as a borated succinimide.
  • the present invention has been achieved on the basis of the finding.
  • the present invention is a lubricant composition
  • a lubricant composition comprising a major amount of a lubricant base oil having added thereto a minor amount of additives comprising (A) oxymolybdenum dithiocarbamate sulfide having alkyl groups with 8 to 18 carbon atoms, (B) zinc dialkyldithiophosphate having primary alkyl groups with 1 to 18 carbon atoms, (C) one or more additional peroxide decomposing sulfur compounds, (D) an ashless dispersant, and (E) a boron containing additive in an amount sufficient to provide at from 0.005 to 0.06 % by weight boron to the finished lubricant wherein to the total weight of the composition, the molybdenum content from oxymolybdenum dithiocarbamate sulfide is at 200 to 2,000 ppm (ratio by weight); the phosphorous content from zinc dialkyldithiophosphate is at 0.02 to 0.15 % by
  • the additional peroxide decomposing sulfur compound is selected from the group consisting of zinc dialkyidithiocarbamate, copper dialkyidithiocarbamate or nickel dialkyidithiocarbamate wherein the dialkyidithiocarbamate has alkyl groups with 2 to 18 carbon atoms, bis(dialkylthiocarbamoyl)disulfide having an alkyl group with 2 to 18 carbon atoms, disulfide having an alkyl group with 2 to 18 carbon atoms, disulfide having an allyl group, an alkylallyl group or an allylalkyi group, with 6 to 18 carbon atoms, olefin sulfide, fish oil sulfide, whale oil sulfide and mixtures of the any of the foregoing.
  • the lubricant also comprises (F) from 1 to 10 % by weight of one or more metal detergents selected from the group consisting of calcium salicylate, magnesium salicylate, calcium sulfonate, magnesium sulfonate and calcium phenate.
  • the metal detergent is added at level providing from 0.5 to 8 percent by weight on an active ingredient basis.
  • One lubricant within the present invention includes from 1.75 to 4 wt % (active ingredient basis) of calcium salicylate.
