Abstract: The fuels contain as detergent materials (A) diamides from 12-20C fatty acids and polyamines with 2-6C and 2-4N atoms, and (B) esters from 12-20C fatty acids and ethanol- or propanolamine. Pref. they also contain (C) a steric-hindered phenol contg. bulky alkyl substits. as anti-oxidant, and (D) residual oils from nonanol and decanol synthesis by the OXO process, as solvent modifiers for (A) and (C) and upper lubricants. Amt. of (A+B) or (A+B+C) is pref. 20-2000 (50-500) ppm. Ratio of (A); (B) (C) is pref. from 1:1:8 to 8:1:1 and of (A+B+C) : (D) is from 9:1 to 1:9. The additives prevent gum and resin deposits in carburetorrs, which interfere with the fine adjustments required for complete combustion and minimum hydrocarbon and CO contents in the exhaust gases.
