The present invention relates to fuel/water emulsions essentially comprising 60 to 80% by weight of a fuel, 0.5 to 5% by weight of one or more water-soluble and gasoline-insoluble emulsifiers of the formulaewhere R is alkyl or alkenyl having in each case 8 to 18 carbon atoms or C9-C14-alkylphenyl and x is a number from 8 to 30, orin which the proportion of the ethylene oxide units is between 40 and 80% by weight of the molecular mass, orwhere x is a number between 8 and 30, and 1 to 10% by weight of a water-soluble and gasoline-insoluble poly(alkylene glycol) as stabilizer, also water and, if appropriate, other additives to 100% by weight. The emulsions according to the invention can be used for operating internal combustion engines. |
