Abstract:
Novel uses of copolymers for removing and/or reducing the level of deposits in the fuel system and/or injection system of direct injection diesel and/or gasoline engines are provided. What is provided is the use of particular copolymers as fuel additive or lubricant additive; to processes for preparation of such additives, and fuels and lubricants added therewith, such as, more particularly, as a detergent additive; to use of these copolymers for reducing the level of or preventing deposits in the fuel systems and especially the injection systems of direct injection diesel engines, especially in common rail injection systems, for reducing the fuel consumption of direct injection diesel engines, especially of diesel engines with common rail injection systems, and for minimizing power loss in direct injection diesel engines, especially in diesel engines with common rail injection systems; and as an additive for gasoline fuels, especially for operation of DISI engines.

Claim (Index 13):
A fuel composition, lubricant composition or kerosene composition, comprising a copolymer, wherein the copolymer comprises in copolymerized form:\n (A) at least one ethylenically unsaturated mono- or dicarboxylic acid or derivatives thereof, (B) at least one \u03b1-olefin having from at least 12 up to and including 30 carbon atoms, (C) optionally at least one further aliphatic or cycloaliphatic olefin which has at least 4 carbon atoms and is different than (B) and (D) optionally one or more further copolymerizable monomers other than monomers (A), (B) and (C), selected from the group consisting of (Da) vinyl esters, (Db) vinyl ethers, (Dc) (meth)acrylic esters of alcohols having at least 5 carbon atoms, (Dd) allyl alcohols or ethers thereof, (De) N-vinyl compounds selected from the group consisting of vinyl compounds of heterocycles containing at least one nitrogen atom, N-vinylamides and N-vinyllactams, (Df) ethylenically unsaturated aromatics, (Dg) \u03b1,\u03b2-ethylenically unsaturated nitriles, (Dh) (meth)acrylamides and (Di) allylamines, and\n optionally partly hydrolyzing anhydride functionalities present in the copolymer and/or partly hydrolyzing carboxylic ester functionalities present in the copolymer, wherein more than 90% of the anhydride and carboxylic ester functionalities present remain intact after the optionally partly hydrolyzing.
