Definitions

  • the invention relates to the field of lubricant compositions, in particular the fuel economy (FE or fuel eco ) properties of lubricant compositions.
  • the invention relates to the combined use of at least one molybdenum derivative and at least one boron derivative to preserve the fuel economy (FE or fuel eco ) properties of a lubricating composition also comprising at least one based.
  • the invention also relates to the use, within a lubricating composition comprising at least one base oil, of a combination of at least one molybdenum derivative and at least one boron derivative, for preserving the properties of fuel economy (FE or fuel eco ) of this lubricating composition.
  • Lubricating compositions for engines must therefore fulfill numerous objectives.
  • the lubrication of parts sliding on each other plays a decisive role, in particular to reduce friction and wear, in particular allowing fuel savings.
  • An essential requirement of engine lubricant compositions relates to environmental aspects. It has become essential to reduce oil consumption as well as fuel consumption, in particular with the aim of reducing CO 2 emissions.
  • the nature of lubricant compositions for motor vehicles has an influence on fuel consumption.
  • Lubricating compositions for motor vehicles for energy savings are often called fuel eco (FE), in English terminology. Reducing energy losses is therefore a constant research in the field of automotive lubricants.
  • the invention relates to the combined use of at least one molybdenum derivative and at least one boron derivative to maintain the properties of fuel economy (FE or fuel eco ) of a lubricating composition also comprising at least one base oil and at least 30 ppm or at most 600 ppm of boron relative to the weight of lubricating composition.
  • the conservation of the fuel economy properties is preferably measured for the used lubricating composition compared to the new lubricating composition.
  • lubricating composition is meant more particularly an oxidized lubricating composition, the oxidation level of which would correspond to the aging of this composition under the actual conditions of use.
  • the conservation of the fuel economy properties is measured for the used composition, preferably after approximately 10,500 km (6,500 miles) traveled by the vehicle.
  • the conservation of fuel economy properties can also be measured for an engine running time corresponding to an interval between two oil changes of an engine.
  • the conservation of the fuel economy properties is greater than 25%, preferably greater than 50%, or even 80 or 99%.
  • the conservation of the fuel economy properties according to the invention is preferably implemented with an organomolybdenum compound, in particular a compound chosen from a molybdenum dithiocarbamate derivative (MoDTC), a molybdenum dithiophosphate derivative (MoDTP) or a molybdenum complex free sulfur.
  • MoDTC molybdenum dithiocarbamate derivative
  • MoDTP molybdenum dithiophosphate derivative
  • molybdenum complex free sulfur a molybdenum complex free sulfur.
  • Molybdenum dithiocarbamate compounds are complexes formed from a metal nucleus linked to one or more ligands independently chosen from alkyl dithiocarbamate groups.
  • the MoDTC compound of the compositions used according to the invention may comprise from 1 to 40%, preferably from 2 to 30%, more preferably from 3 to 28%, even more preferably from 4 to 15% by mass of molybdenum, relative to the total mass of the MoDTC compound.
  • the MoDTC compound used according to the invention can be chosen from compounds whose nucleus comprises two molybdenum atoms (dimeric MoDTC) and compounds whose nucleus comprises three molybdenum atoms (trimeric MoDTC).

  • X 1 and X 2 can represent a sulfur atom and X 3 and X 4 can represent an oxygen atom.
  • X 1 and X 2 can represent an oxygen atom and X 3 and X 4 can represent a sulfur atom.
  • the MoDTC compound of formula (A) can also be chosen from at least one symmetrical MoDTC compound, at least one asymmetric MoDTC compound and their combinations.
  • symmetrical MoDTC compound is meant a MoDTC compound of formula (A) in which the groups R 1 , R 2 , R 3 and R 4 are identical.
  • asymmetric MoDTC compound is meant a MoDTC compound of formula (A) in which the groups R 1 and R 2 are identical, the groups R 3 and R 4 are identical and the groups R 1 and R 2 are different from the groups R 3 and R 4 .
