Abstract:
A combustible fuel composition of diesel fuel and additive as a clear microemulsion with water present wherein said additive comprises:(a) ethanol having between 0.5 and 25% water by volume of ethanol; (b) one or more alcohols selected from the group consisting of: (i) straight- or branched-chain alcohols having between 3 and 5 carbon atoms (ii) straight- or branched-chain alcohols having between 6 and 12 carbon atoms, and (iii) combinations of b(i) and b(ii); (c) a fatty acid of the structure Râ€”(C&boxH;O)â€”OH, wherein R is alkyl or alkylene having between about 10 to 24 carbon atoms, in combination with ammonia or urea in an anhydrous state or as an aqueous solution; wherein components a, b, and c, as the additive when combined with mixing with diesel fuel form a clear, stable microemulsion fuel composition having a viscosity within Â±10% of the original viscosity of the diesel fuel, and wherein the ratio of diesel fuel to additive ranges from about 50:50 to 99:1 by volume, with the proviso that water is present in the composition sufficient to form the microemulsion and with the proviso ethylene oxide condensation and ethylene oxide esterification products are completely eliminated.
