Abstract
A micro-emulsion forming (nanotechnology) fuel additive composition is disclosed which improves the fuel economy and reduces the exhaust emissions of internal combustion machines when used at a cost effective dose level of about 20 to 500 ppm in the fuel.
Claims4
A method to improve the fuel economy of a combustion machine, comprising:
- 1) producing a fuel additive composition, comprising in admixture form:
- a) a surfactant selected from the group consisting of non-ionic, anionic, cationic, amphoteric and mixtures thereof;
- b) optionally, a co-surfactant selected from the group consisting of methanol, ethanol, propanol, butanol, ethylene glycol, propylene glycol, ethylene glycol n-butyl ether, dipropylene glycol methyl ether and mixtures thereof;
- c) optionally, kerosene;
- and
- d) water,
- 2) providing a liquid hydrocarbon fuel,
- 3) producing a fuel composition by dosing said liquid hydrocarbon fuel with from about 20 to about 500 ppm by weight of said fuel additive such that said fuel composition comprises:
- a) from about 11 to about 400 ppm by weight of said surfactant;
- b) from about 0 to about 100 ppm by weight of said co-surfactant;
- c) from about 0 to about 150 ppm by weight of said kerosene;
- and
- d) from about 5 to about 95 ppm by weight of said water, such that;
- the weight ratio of said surfactant to said water is from about 8:1 to about 0.5:1, and
- 4) operating said combustion machine using said fuel composition.
