ABSTRACT:
A fuel for gasoline engines contains a small amount of a copolymer of an olefin of from 2 to 40 carbon atoms and/or a cycloolefin of from 3 to 10 carbon atoms with maleic anhydride and/or a copolymer of an alkyl vinyl ether of from 1 to 30 carbon atoms in the alkyl group and/or a cycloalkyl vinyl ether of from 3 to 10 carbon atoms in the alkyl group with maleic anhydride and/or a copolymer of an alkyl vinyl ether of from 1 to 30 carbon atoms in the alkyl group and/or a cycloalkyl vinyl ether of from 3 to 10 carbon atoms in the alkyl group and an olefin of from 2 to 40 carbon atoms and/or a cycloolefin of from 3 to 10 carbon atoms with maleic anhydride having a total molecular weight of from 500 to 20,000 g per mole, the carboxyl groups on the copolymer having been wholly or partly converted with an alkali metal or alkaline earth metal to form an alkali metal or alkaline earth metal salt and the remaining carboxyl groups having been converted with an alcohol and/or an amine of up to 50 carbon atom into the corresponding ester and/or amide groups and/or ammonium salts.
