Abstract (en)
[origin: FR2753455A1] The invention concerns a detergent and anti-corrosive additive for engine fuels, in particular gas oil, containing amide or imide functions characterised in that it is obtained by mixing wt.60 to 90 % of a compound A consisting of at least one carboxylic polyalkenyl, diacid or anhydride, of average molecular mass between 200 and 3000, wt. 0.1 to 10 % of a compound B consisting of at least one carboxylic compound, monoacid or anhydride, containing 1 to 6 carbon atoms per chain and 10 to 30 % of a compound C consisting of at least one primary polyamine of general formula H2N - [- (CHR1- (CH2)p - CHR2)n - NH]m- H, the mol ratios A/B/C corresponding to 1/(0.1 to 1)/(1 to 3), A/B/C never being 1/1/1.
