ABSTRACT:
The present invention relates to an additive composition for a combustible fuel to produce improved combustion and reduced exhaust pollution of the combusted fuel, which additive composition comprises:a) one or more water-soluble alcohols having between 1 and 5 carbon atoms, in an anhydrous state or as a 0.5-36% aqueous solution, and one or more of the following:b) one or more straight- or branched-chain alcohols having between 6-18 carbon atoms;c) one or more ethoxylated alcohols having between 12 and 18 carbon atoms where the ethylene oxide add-on is less than 5 moles;d) a fatty acid of the structure R—(C═O)—OH having from 10 to 24 carbon atoms withe) a source of nitrogen in an anhydrous state or as an aqueous solution; wherein components a) to e), when combined with mixing with said combustible fuel, form a clear, stable microemulsion having a viscosity similar to the liquid fossil fuel. Combustion is improved and pollutant and particulate levels are reduced.
