Abstract:
The use of a copolymer as a detergent additive in an internal combustion engine liquid fuel. The copolymer obtained by copolymerization of at least: an alkyl acrylate or alkyl methacrylate monomer ma and a styrenic monomer mb chosen from styrenics derivatives, the aromatic ring of which is substituted by at least one group R or at least one linear or branched C 1  to C 12  hydrocarbon-based chain substituted by at least one group R being chosen from: the hydroxyl group, a group —OR′, a group —(OC y H 2y O) f —H, a group —(OC y H 2y O) f —R′, a group —O—(CO)—R′, and a group —(CO)—OR′, where y is an integer ranging from 2 to 8, f is an integer ranging from 1 to 10, and R′ is chosen from C 1  to C 24  alkyl chains. Also, a process for maintaining the cleanliness of and/or for cleaning at least one of the internal parts of an internal combustion engine.

Claim (Index 37):
The method as claimed in any  claim 26 , wherein the copolymer is used in the liquid fuel to:\n keep clean and/or to clean-up at least one of the internal parts of an internal combustion engine, or limit or prevent the formation of deposits in at least one of the internal parts of an internal combustion engine, or reduce the existing deposits in at least one of the internal parts of said engine.
