Abstract:
In a specific embodiment of this invention, deposits and soot formation in a direct injection engine are reduced by passivating the injectors to within 0.1 mm of the injector nozzle. The fuel used with the inventive injectors comprises fuel-soluble additives.
Abstract:
A dye formulation is disclosed that includes a vegetable oil ester based solvents that have carbon chain lengths of C-1 to C-18, a solvent dye that is a true liquid dye dissolved in the vegetable oil ester for imparting color to the dye formulation, and reduced sulfur levels in commercially available dye formulations as compared to those in hydrocarbon based solvent systems. Sulfur content is typically reduced to 2-3 percent of dye formulations in hydrocarbon based solvents. The formulations are particularly useful for tagging petroleum substrates as well as writing instrument and ink jet formulations.
Abstract:
The present invention relates to an apparatus and method for delivering tungsten from a to a fuel combustion system or to the exhaust therefrom. By the present invention, tungsten from the lubricant or the fuel will interact with iron from the combustion process. In this manner, the tungsten scavenges or inactivates iron that can otherwise poison catalytic converters, sensors and/or automotive on-board diagnostic devices and/or reduce the operation of spark plugs. The present invention can also lead to improved durability of exhaust after treatment systems. Supplying tungsten acts to change the characteristics of iron deposits formed by combusting a fuel with iron.

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:
The present invention provides a composition comprising: i) at least one compound of formula (I): wherein R1 and R2 are independently selected from a group consisting of hydrogen, unsubstituted or substituted C1-19 hydrocarbyl or a group of formula (II): wherein Q is a bond or an unsubstituted or substituted hydrocarbyl group; wherein R3 is selected from a group consisting of hydrogen and unsubstituted or substituted C1-18 hydrocarbyl; wherein the R1—C—R2 backbone is from 5 to 20 atoms in length; wherein each A and B is independently an unsubstituted or substituted unsaturated cyclic hydrocarbyl group; and wherein n is an integer from 0 to 10; and ii) a diluent or carrier; wherein the compound(s) of formula (I) is present in an amount sufficient to provide, at −30° C., at least 1 wt % of iron, based on the weight of the composition.
Abstract:
Fuel additives are disclosed for high-asphaltene carbonaceous fuels such as residual fuel oil or coal. Such additives provide improved combustion characteristics. Such improved combustion characteristics include one or both of improved efficiency and decreased emissions of pollutants. In particular, the fuel additives include an extract from a plant such as fescue, alfeque, or alfalfa, and optionally, an organometallic compound. The use of a fuel additive including both a plant extract and an organometallic compound is particularly useful in improving the combustion characteristics of fuels with particularly high asphaltene content.
Abstract:
Tropospheric volume elements enriched with vital elements and/or protective substances as well as procedures for their production and application. The term “vital elements” applies to all matter supporting the development of life within the earth's biosphere and the term “protective substances” means all those substances which contribute directly or indirectly to the prevention of harmful effects on the earth's biosphere and in particular on man. Tropospheric volume elements in the form of clouds which contain contaminants and which can escape from industrial facilities due to damage or malfunction are enriched with protective substances which prevent the organism from taking in radioactive elements and minimize the extent of the area affected by the clouds and possess additional warning and identification properties.
Abstract:
A fuel additive composition comprises (a) a Mannich reaction product and (b) a polyetheramine where the weight ratio on an actives basis of component (a) to component (b) is 1:4-10. A fuel composition and a method for removing intake valve deposits and combustion chamber deposits in a spark-ignited internal combustion engine comprise the fuel additive composition which is very effective in removing the deposits.
Abstract:
The present disclosure provides compositions and methods for improving corrosion inhibition in engines combusting a fuel containing ethanol. In particular, E85 fuels are provided containing additives able to reduce, eliminate and/or prevent corrosion of engine combustion surfaces and surfaces of engine components exposed to the fuel containing ethanol.
