Abstract:
PROBLEM TO BE SOLVED: To provide a method for reducing combustion chamber deposit peel-off and a spark ignited internal combustion engine. SOLUTION: The method includes supplying a fuel having an additive that includes a metal-containing compound to a spark ignited internal combustion engine. The metal-containing compound is supplied in an amount effective to reduce combustion chamber deposit peel-off. In one example, the metal is manganese and the additive compound is MMT. The reduction or elimination of combustion chamber deposit peel-off means a reduction in cold start emissions originating from the engine. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
A method to improve the operation of a diesel trap through the use of a fuel additive comprising fuel-soluble compositions of platinum group metal in effective amounts to lower the emissions of unburned hydrocarbons and carbon monoxide from the trap. The catalyst is selective and reduces the oxidation of SO2 to SO3. The platinum group metal compositions are preferably added in amounts effective to provide concentrations of the metal in the fuel of less than 1 part per million (ppm). Lithium and/or sodium compositions can be used in amounts effective to reduce the trap regeneration temperature, e.g. concentrations to provide about 1 to 100 ppm lithium metal, and/or 1 to 30 ppm sodium metal.
Abstract:
PROBLEM TO BE SOLVED: To provide a means for improving the performance of an exhaust gas after-treatment system in a combustion system. SOLUTION: An additive containing fuel and a manganese compound is supplied into the combustion system. The fuel is burned in a combustion chamber to generate at least one by-product containing the manganese compound. The manganese compound is supplied with an amount effective to form the combustion by-product and a compound. The combustion system may contain a catalyst or, alternatively, a continuously regenerative diesel particulate filter. COPYRIGHT: (C)2004,JPO
Abstract:
A safe, metal-containing combustion additive and a method of formulation is directed for use in connection with utility and industrial furnaces. The additive includes a metal-containing catalyst, a ligand for complexing with the catalyst and a solvent for carrying the catalyst/ligand complex. The vapor pressure of the additive is less than about 200×10−5 Torr at 100° F.
