Abstract (en)
[origin: EP0530094A1] Additive formulation for engine fuels comprising at least one constituent (A) and at least one constituent (B), the said constituent (A) consisting of at least one composition containing the products resulting from the reaction of at least one dicarboxylic compound (D) in which the carboxylic functional groups are separated by not more than 6 carbon atoms, with at least one glycol or polyoxyalkylene glycol monoether (E) of general formula (I): R<1>-O-(R<2>-O)n-H in which R<1> denotes a hydrocarbon group containing from 1 to 30 carbon atoms, R<2> denotes a divalent hydrocarbon group containing from 2 to 6 carbon atoms and n is a number from 1 to 60; and the said constituent (B) consisting of at least one detergent-dispersant product. This formulation preferably additionally includes a constituent (C) chosen from the group made up of mineral or synthetic lubricating oils and polyglycols which are soluble in the fuel. Use as multifunctional additives for fuels employed in internal combustion engines, in particular for those employed in spark ignition engines.
