Definitions

  • the present invention relates to a lubricant composition comprising a friction- reducing additive with enhanced oxidative stability.
  • Lubricant compositions containing friction-reducing additives have been known for several years. Originally such compositions were used as slip gear oils, automatic transmission fluids, slideway lubricants and multipurpose tractor fluids. Such compositions made use of friction reduction to meet requirements for smooth transition from static to dynamic conditions as well as reduced noise, frictional heat and start-up torque.
  • Engine friction originates from several components, which operate at different conditions of load, speed and temperature. Hence, these components may experience various combinations of (elasto) hydrodynamic, mixed and boundary lubrication during engine operation. For each of these regimes, there are a number of factors that govern engine friction.
  • Friction-reducing additives that have been used fall into three main chemically- defined categories, which are organic, metal organic and oil insoluble.
  • the organic friction-reducing additives themselves fall within four main categories which are carboxylic acids or their derivatives, which includes partial esters, nitrogen- containing compounds such as amides, imides, amines and their derivatives, phosphoric or phosphonic acid derivatives and organic polymers.
  • carboxylic acids or their derivatives which includes partial esters, nitrogen- containing compounds such as amides, imides, amines and their derivatives, phosphoric or phosphonic acid derivatives and organic polymers.
  • nitrogen- containing compounds such as amides, imides, amines and their derivatives, phosphoric or phosphonic acid derivatives and organic polymers.
  • friction reducing additives are glycerol monooleate and oleylamide.

Sequence Vl-B includes ageing stages of 16 and 80 hours in order to determine fuel economy as well as fuel economy longevity. These ageing stages are equivalent to 4000 - 6000 miles of mileage accumulation required prior to the EPA Metro / Highway Fuel economy test. That test is used in determining the CAFE parameter for a vehicle.

  • the friction-reducing additive may further comprise an ester.
  • the ester may be derived by direct esterification of an acid, acid chloride or acid anhydride with an alcohol or it may be derived by transesterification of an ester with an alcohol. Preferably it is derived by direct esterification of at least one acid with at least one alcohol.

  • the at least one alcohol may be partially or fully esterified. Preferably it is partially esterified.
