This invention pertains to an improved energy-saving fuel additive for jet engines, gasoline and diesel engines, including additions to domestic heating and light industrial oils (#2 and #3) and residual or bunker fuel (#4, #5, and #6), which comprises as active ingredients a catalytic mixture of a major proportion of picric acid and a minor proportion of cupric sulfate. ______________________________________ Cupric sulfate .01-.03% Picric acid 1-2% Methanol 35-50% Isopropyl alcohol 15-5% Toluene 43-48% Nitrobenzene .6-1.0% Primene 81R .5-1.0% ______________________________________ Additional variations include (1) the replacement of the toluene with about 10% methanol and 90% isopropyl alcohol for toxicity reasons and (2) replacement of the toluene with 10% methanol, 45% isopropyl alcohol, and 45% kerosene as a cost-reducing factor. A preferred additive is: ______________________________________ Cupric sulfate .02% Picric acid 1.54% Methanol 35% Isopropyl alcohol 15% Toluene 48.3% Nitrobenzene .8% Primene 81R .05% ______________________________________
A fuel additive for jet, internal combustion, and diesel engines comprising an active ingredient formulation of a mixture of picric acid and cupric sulfate in a relationship of about 0.01 to 0.75-1.0 cupric sulfate to picric acid by weight percent in a mixed solvent of methanol, isopropyl alcohol, toluene, nitrobenzene, and a tertiary alkyl amine which is a cross of primary aliphatic amines of the general formula R.sub.1 (R.sub.2)(R.sub.3)CNH.sub.2.
An additive comprising the following make up:
