Abstract: The invention relates to fuels for spark-ignition engines, containing small quantities of copolymers of alkyl (meth)acrylates having 8 to 40 C atoms in the alkyl radical and/or vinyl esters of carboxylic acids containing 8 to 40 C atoms and monoethylenically unsaturated mono- and/or di-carboxylic acids having 3 to 12 C atoms and/or monoethylenically unsturated compounds with sulphonic and/or phosphonic acid groups, having a total molecular mass from 500 to 20,000 g per mole, the carboxyl groups, sulphonic acid groups and phosphonic acid groups of the copolymers having been wholly or partially reacted with alkali or an alkaline earth to form the alkali metal salts or alkaline earth metal salts and the remainder of the acid groups having been reacted with ammonia and/or amines having up to 50 C atoms to give the corresponding amide groups and/or ammonium salts.

Abstract: The invention relates to fuels for spark-ignition engines, comprising small quantities of alkali metal or alkaline earth metal salts of monoamides of dicarboxylic acids, of the general formula in which R and R are identical or different, substituted or unsubstituted, optionally monoolefinically unsaturated hydrocarbon radicals having 5 to 75 carbon atoms, or R is H and R is where n = 3 and/or 4 and y = from 5 to 100, in which R and R are identical or different, unsubstituted or substituted hydrocarbon radicals having 1 to 18 and preferably 4 to 13 carbon atoms, -A- is -CH=CH- or -(CH2)x- where x = from 2 to 4 and M is Li, Na, K, Rb, Cs, Ca/2 or Mg/2.
