Abstract:
A fuel additive containing ferrous picrate produced by a process involving placing wire composed of an alloy of iron in any solution of picric acid in a solvent that is known in the art for reacting with iron to produce ferrous picrate. The wire can be suspended in the solution or placed upon the bottom of a reaction vessel that holds the solution. Preferably the wire is loosely coiled, at least when placed upon the bottom of a reaction vessel. Also preferably, after a concentrated fuel additive has been prepared, to the concentrate is added so much of a pre-mix solution produced by the steps of (a) dissolving picric acid in the same kind of solvent that was utilized to produce the solution into which the steel wool was placed and (b) removing water from the precursor to the pre-mix solution thus produced and so much of the same kind of alcohol that was utilized to produce the solution into which the steel wool was placed that the final product produced thereby contains approximately 1.9 percent free picric acid and 15 to 16 percent of the alcohol.
Abstract:
A reduction in the formation and presence of peroxides in low sulfur diesel fuels is obtained through the combination of those fuels with an organic nitrate combustion improver. The reduction in the amount of peroxides means that the fuel system elastomers will be more durable, as they are not being corroded by as much peroxide formed in the fuel, fuel color durability is improved, fuel stability is enhanced, and fuel sediments are reduced.
Abstract:
An emergency fuel for an internal combustion engine comprises a hydrocarbon solvent having a flash point of at least 100° F. (such as about 65-75% paraffins and about 25-35% naphthenes, or about 75-85% paraffins and about 15-25% of C7 or higher alcohols, or an aromatic solvent, or an naphthalene-depleted aromatic solvent) and a cold starting additive. The cold starting additive may be provided in an amount of less than 5,000 ppm, preferably between about 1 ppm and 150 ppm. The cold starting additive is preferably selected from peroxides, azo compounds, cyano compounds, cetane improvers, or combinations of these compounds. When the emergency fuel is added to a cold engine, including one substantially at room temperature, the engine may be easily started.
Abstract:
A method of formulating a fuel emulsion composition for use in a specified compression ignition engine in which the fuel composition includes a hydrocarbon petroleum distillate, purified water; alcohol; and an additive composition comprising various ingredients. The types and amounts of the fuel and alcohol are selected so that the sum of its net heating value (lower heating value * percent of total composition) and the net heating value of the additive composition yields a net heating value of the aqueous fuel composition that is within the operating parameters for fuel heating values for the engine.
Abstract:
The present invention relates generally to a composition and method for increasing the amount of cetane in fuel. More specifically, it was discovered that the amount of cetane in fuel can be increased by mixing a fuel additive comprising &bgr;-carotene that was prepared in an inert atmosphere.
Abstract:
The present invention relates to diesel fuel compositions that are extremely stable against thermal degradation, sedimentation, and discoloration. The diesel fuel compositions of the present invention are void or essentially void of certain heteroatomic compounds often present in diesel fuel and which have been discovered to cause the thermal degradation in the presence of nitrate-based cetane improver additives. The specific deleterious heteroatomic compounds include pyrroles, indoles, sulfides, disulfides, mercaptans, thioacids, sulfonic acids, and indolines.
Abstract:
A splash-blendable, solubilized diesel fuel composition includes a diesel fuel, ethanol, a stabilizing additive and, optionally, an alkyl ester of a fatty acid and/or a co-solvent. The stabilizing additive is either a mixture of fatty acid alcohols, a polymeric material, or a combination of the mixture and the polymeric material.
Abstract:
Smoke and nitrogen oxide in exhaust gases of diesel engines are reduced by burning a diesel fuel composition having a major portion of diesel fuel and 0.1 to 40 vol. % of a carbonic acid diester of the formula: in which R represents a lower hydrocarbon group having 1 to 6 carbon atoms, in a diesel engine by injecting the diesel fuel composition into a crank case at an injection timing of 17 to 2° CA, preferably, 14 to 8° CA, in terms of BTDC. EGR (exhaust gas recirculation system) is advantageously employable.
