  • Lubricant composition for an engine
    Patent number: 10604717
    Abstract: The present disclosure relates to lubricant compositions for an engine, including at least one base oil, at least one polymer for improving the viscosity index, at least one organomolybdenum compound, and at least one polyalkylene glycol, obtained by polymerizing or copolymerizing alkylene oxides including from 3 to 8 carbon atoms, at least of which is butylene oxide, the polyalkylene glycol content being from 1 to 28% by weight relative to the total weight of lubricant composition. The use of at least one polyalkylene glycol, obtained by polymerizing or copolymerizing alkylene oxides including 3 to 8 carbon atoms, at least one of which is butylene oxide, in a base oil enables a reduction in the wear of the connecting-rod bearings of the thermal internal combustion engines of vehicles with hybrid and/or micro-hybrid engines.

  • LUBRICATING COMPOSITION WITH PHASE-CHANGE MATERIAL
    Publication number: 20170349850
    Abstract: Disclosed is a monophasic lubricating composition including a base oil, an oil chosen from the polyalkylene glycols (PAG) and a phase-change material, in particular water. The monophasic lubricating composition can be used, in particular, for lubricating a vehicle engine. It has improved thermal performance relative to the lubricant compositions of the prior art. It also helps reduce fouling of the engine parts.
