Title:
LUBRICANT COMPOSITION FOR INTERNAL COMBUSTION ENGINES
Document Type and Number:
WIPO Patent Application WO/2023/048075
Kind Code:
A1
Abstract:
The present invention provides a lubricant composition for internal combustion engines, the lubricant composition containing (A) a lubricant base oil, (B) an organic molybdenum compound, (C) an alicyclic epoxy compound, (D) triazole or a triazole derivative and (E) at least one ashless friction modifier that is selected from among an amino acid compound, an amine compound, a urea compound and a fatty acid ester compound, each having an alkyl group, alkenyl group or acyl group having 12 to 30 carbon atoms, and derivatives of these compounds, and the lubricant composition being configured such that the amount of molybdenum derived from the component (B) is 400 ppm by mass or more based on the total amount of the composition and the amount of nitrogen derived from the component (E) is 400 ppm by mass or less based on the total amount of the composition. This lubricant composition for internal combustion engines is capable of achieving improved corrosion resistance, while maintaining fuel consumption saving both at low temperatures and high temperatures.
