Abstract (en)
[origin: WO2020212562A1] The present invention relates to the use of a copolymer (C) comprising repetitive units corresponding to alkyl methacrylate monomers, said monomers comprising at least: - one or more identical or different monomers (A) selected from (C6-C10) alkyl methacrylate monomers; - one or more identical or different monomers (B) selected from (C10-C18) alkyl methacrylate monomers, in a lubricating 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.
