Abstract
A water in diesel oil fuel micro-emulsion for internal combustion diesel engines, with a low content of surfactants, a very long shelf-life, a reduced production of pollutants and carbonaceous side-products generated by the combustion and very good engine performance, is described. These emulsions comply with the strict requirements of Italian regulations and are particularly useful as fuels for automotive and heating applications.

Emulsifying composition for water in diesel oil fuel micro-emulsions comprising:
- from about 20.0% to about 33.0% by weight of at least a non-ionic polymer, selected among polyglycerides of mono-, di- and tri-glycerides of fatty acids, polyethylene glycols, polyvinyl alcohols, polyvinylpyrrolydone (PVP), vinylpyrrolidone (VP)/vinyl acetate (VA) copolymers, vinyl methacrylate (VMA)/acrylamide (AM) copolymers, ethyl-, ethylmethyl-, ethylhydroxy-, hydroxyl-, methyl-, hydroxypropyl-cellulose, natural gums—such as karaya gum, tragacanth gum, carob bean gum—and admixtures thereof;
- from about 6.0% to about 10.0% by weight of at least a lipophilic non-ionic surfactant, having HLB lower than about 7;
- from about 16.0% to about 29.0% by weight of at least a hydrophilic non-ionic surfactant having HLB higher than about 10;
- from about 6.5% to about 11.5% by weight of at least an anionic surfactant selected among organic sulfates, sulfonates, phosphates and carboxylates salts;
- and
- from about 9.5% to about 16.5% by weight of at least an amphoteric surfactant.
