    Abstract: Otto cycle engine fuels, for example gasoline, can be improved to such an extent by additives that no deposits or residues form in the carburetor or on the valves. In accordance with the invention esters, amides or imides of hydroaromatic polycarboxylic acids are added which are very effective in cleaning the carburetor and the valves.
