Abstract
Abstract PCT No. PCT/US80/01530 Sec. 371 Date Mar. 10, 1981 Sec. 102(e) Date Mar. 10, 1981 PCT Filed Nov. 17, 1980 PCT Pub. No. WO82/01718 PCT Pub. Date May 27, 1982.An improved energy-saving fuel additive for diesel engines and gasoline engines which comprises separate compositions which raise the flash point from about 6 DEG to 29 DEG C. In the case of the diesel additive, the following formulation is preferred: Elemental iron: 0.01% Methyl isobutyl ketone: 5.0% Picric acid: 1.5% Normal butyl alcohol: 20.0% Kerosene: 73.0% Nitrobenzene: 0.08% Primene 81R: 0.05% The composition of the agent for gasoline to high flash point is somewhat different and may be noted as follows: Copper carbonate hydroxide: 0.02% Methyl isobutyl ketone: 5.0% Normal butyl alcohol: 20.
