Definitions

  • the present invention relates to a novel lubricant oil composition. More specifically, the present invention relates to a lubricant oil composition with a small friction coefficient under a wide variety of applicable conditions, particularly under operating conditions at a medium to low oil temperature and a low-speed rotation, which is preferable as a lubricant oil composition for internal combustion engines such as automobile engines for sustaining a fuel-efficiency.
  • Lubricant oils for internal combustion engines have roles in lubricating principally a variety of sliding parts such as piston rings/cylinder liners, bearings of a crank shaft and connecting rods, valve mechanism inclusive of cams and valve lifters, and the like, as well as in cooling the inside of an engine and cleaning to disperse combustion products and furthermore preventing rust and corrosion.
  • Lubricated engine parts are mostly in the state of fluid lubrication, but valve systems and top and bottom dead centers of pistons are likely to be put in the state of boundary lubrication.
  • the wear preventing property in such a state of boundary lubrication is generally given by the addition of zinc dithiophosphate and zinc dithiocarbamate.
  • the objective of the present invention is to improve the property of sustaining the fuel-coefficiency of a lubricant oil composition with a smaller friction coefficient, the composition being blended with a molybdenum-containing friction conditioner, more specifically, to provide a lubricant oil composition blended with a molybdenum-containing friction conditioner, the composition satisfying the coke deposit criterion of the GF-2 standard on hot tube coking test.
  • coke deposit can be decreased prominently by adding a specific amount of a specific compound having a higher boron content into a lubricant oil composition with friction properties improved by use of a molybdenum series additive.
