Abstract
The present invention relates to the use of a copolymer (C) comprising repeat units corresponding to alkyl methacrylate monomers, said monomers comprising at least one or more monomer(s) (A), the same or different, selected from among (C6-C10) alkyl methacrylate monomers; one or more monomer(s) (B), the same or different, selected from among (C10-C18) alkyl methacrylate monomers, in a lubricant composition comprising at least one base oil for reducing and/or controlling abnormal gas combustion in an engine, preferably a marine engine or a controlled-ignition engine.

A method for reducing and/or controlling abnormal gas combustion in an engine comprising the addition in a lubricating composition comprising at least one base oil of a copolymer (C) comprising repeat units corresponding to alkyl methacrylate monomers, said monomers comprising at least:
- one or more monomer(s) (A), the same or different, selected from among (C6-C10) alkyl methacrylate monomers;
- one or more monomer(s) (B), the same or different, selected from among (C10-C18) alkyl methacrylate monomers, said monomers (B) differing from said monomers (A).
