Abstract:

The present invention relates to fuel additives, fuel compositions and methods of manufacture in which the additives are provided to impart desired properties to fuels. These properties include, without limitation, reduction of nitrogen oxide and particulate emissions from the exhaust stream of internal combustion engines using the fuels. Preferred embodiments of an additive form of the composition include a nitrogen-containing compound selected from the group consisting of urea, cyanuric acid, triazine, ammonia and mixtures thereof, a carrier blend comprising an alkoxylated alcohol, a polyalkylene glycol ester and an alkanolamide and water. The additive may be provided in a concentrate form by addition of a solvent or may be provided as a final form fuel composition. A method of additive manufacture and is disclosed.

Abstract:

This invention relates to emulsion compositions which are used as auto spray waxes or rinse or drying aids in automatic car washes. The inventive emulsion replaces mineral seal oil of prior art emulsions with more environmentally acceptable simple esters of natural fatty acids having the general structural formula: ##STR1## wherein R--C is from an acid moiety having approximately 12-26 carbon atoms, and R' is from an alcohol moiety having approximately 1-5 carbon atoms. In an additional embodiment, the emulsion composition can include an amine oxide coupling solvent or solubilizer.
