Abstract:
A method of improving the combustion of a fuel by adding a catalyst or combustion enhancer at an extremely low concentration, preferably in the range of 1 part catalyst per 200 million parts fuel to 1 part catalyst per 6 trillion parts fuel. The catalyst or combustion enhancer may be selected from a wide range of soluble compounds. The method may comprise the steps of an initial mixing of the catalyst or enhancer with a suitable solvent and then subsequent dilution steps using solvents or fuel. Suitable solvents include water, MTBE, methylketone, methyisobutylketone, butanol, isopropyl alcohol and other hydrophilic/oleophilic compounds.
Abstract:
A composition of an oil of lubricating viscosity; a polymer, soluble in the lubricant composition and having a number average molecular weight of greater than 50,000; and a combustible solvent in which the remaining components of the lubricant are soluble, provides a composition suitable for lubricating a two-stroke cycle engine. The lubricant composition provides good lubricity with low smoke generation.
Abstract:
The invention provides dispersants and dispersant viscosity index improvers which include polymers of conjugated dienes which have been hydrogenated, functionalized, optionally modified, and post treated. The dispersant substances include a copolymer of two different conjugated dienes. The polymers are selectively hydrogentated to produce polymers which have highly controlled amounts of unsaturation, permitting highly selective functionalization. Also provided are lubricant fluids, such as mineral and synthetic oils, which have been modified in their dispersancy and/or viscometric properties by means of the dispersant substances of the invention. Also provided are methods of modifying the dispersancy and/or viscometric properties of lubricating fluids such as mineral and synthetic lubricating oils. The dispersant substances may also include a carrier fluid to provide dispersant concentrates.

Abstract:
A substantially particulate-free homogeneous lubricant additive includes a first nonionic fluorochemical surfactant selected from the group consisting of fluoroaliphatic oxyethylene adducts and fluoroaliphatic oxypropylene adducts, and a second oil solubilizing nonionic surfactant and a transport or carrier medium ranging from light oil to grease.The additive also utilizes an antioxidant, a petroleum distillate solvent and a bactericide.
