The invention relates to fuels for Otto engines containing small proportions of the alkali-metal or alkaline-earth-metal salts of amic acids of the general formula R1R2N-CO-A-COOH or of analogous partial amides of tricarboxylic or tetracarboxylic acids whose carbamoyl groups have the general formula R1R2N-CO-, where A is the bivalent radical vinylene, ethylene, trimethylene, or tetramethylene and either R1 and R2 are identical or different, substituted or unsubstituted alkyls or alkenyls of from 5 to 75 carbon atoms or R' is hydrogen and R2 is the group of the general formula R3R4N-¢CnH2nO!x-CnH2n-, where R3 and R4 are identical or different hydrocarbon radicals of from 1 to 18 -- preferably from 4 to 13 --carbon atoms, n is 3 or 4 (or 3 and 4), and x is from 4 to 99. |
