Claims
- 1. A fuel for Otto-cycle engines containing, in a detergent effective concentration, an amide of an aminoalkylene polycarboxylic acid of formula I or II ##STR5## or a mixture thereof, or a corresponding amide/ammonium salt of said polycarboxylic, acid wherein one or more, but not all of the amide groups are in the form of a dialkylammonium carboxylate group, in which
- A is a straight-chain or branched-chain alkylene radical of from 2 to 6 carbon atoms or a radical of the formula ##STR6## and R denotes a straight-chain C.sub.12 -C.sub.24 -alkyl radical.
- 2. A fuel as claimed in claim 1, containing one or more compounds of the formulae I and II, in which ##STR7## denotes a ditallow fatty amine radical.
- 3. A fuel as claimed in claim 1, characterized in that it contains other fuel detergents, anticers, corrosion inhibitors and/or antioxidants.
- 4. A fuel as claimed in claim 1, containing one or more compounds of the formula ##STR8## in which R is a straight-chain C.sup.14 -C.sub.24 radical, and some of the amide groups are present in the form of dialkylammonium carboxylate groups of amines of the formula ##STR9##
- 5. A fuel as claimed in claim 4, containing one or more compounds of the formulae I and II, in which ##STR10## denotes a ditallow fatty amine radical.
- 6. A fuel as claimed in claim 1 and containing the compounds of formulae I and II in concentrations of from 50 to 1500 ppm, based on the fuel.
- 7. A fuel as claimed in claim 6, containing one or more compounds of the formulae I and II, in which ##STR11## denotes a ditallow fatty amine radical.
