Abstract:
Disclosed is a leaded motor fuel additive composition which synergistically interacts with the alkyl lead additive to reduce both fuel intake system deposit formation and combustion chamber deposit formation, thereby reducing engine ORI and maintaining desired engine performance.
Abstract:
A jet fuel and jet fuel additive are provided that include a plant oil extract, β-carotene, and jojoba oil. The jet fuel additive may be added to any jet fuel to reduce emissions of undesired components during combustion of the fuel, or to reduce the smoke point of the jet fuel. A method for preparing the jet fuel is also provided.

Abstract:
A motor fuel additive composition comprises a mixture of: (a) from about 5 to about 50 weight percent, based upon the total weight of the additive, of a detergent component selected from the group consisting of (i) a reaction product of a substituted hydrocarbon and an amino compound, and (ii) a polybutylamine or polyisobutylamine; and (b) a fuel conditioner component comprising (i) from about 2 to about 50 weight percent, based upon the total weight of the additive, of a polar oxygenated hydrocarbon compound and (ii) from about 2 to about 50 weight percent, based upon the total weight of the additive, of an oxygenated compatibilizing agent. The fuel conditioner component may additionally comprise a hydrophilic separant, an aromatic hydrocarbon, or mixtures thereof. Additionally, in some cases the hydrophilic separant may also act as the compatibilizing agent. The additive may also additionally comprise a carrier oil or fluidizer. The additive is prepared by mixing together the detergent and fuel conditioner components, and is advantageous in that the detergent and fuel conditioner components synergistically interact to reduce both fuel intake system deposit formation and combustion chamber deposit formation, thereby inhibiting engine ORI.
