Abstract: The invention provides a method employing a fuel additive to improve the operation of a pass-through oxidation catalyst over long periods of time with continued catalytic activity and without the undesirable conversion of SO2 to SO3. A pass-through catalyst support is continuously, selectively catalyzed by the combustion of a fuel containing a platinum group metal composition which burns to release the catalyst metal in active form. The effectiveness of the process is attributed to improved combustion in the engine by the catalyst and the treatment of the catalytic oxidizer with active catalyst metal released during combustion such that, in the exhaust system, the soluble organic fraction of the particulates and the levels of gaseous unburned hydrocarbons and carbon monoxide are significantly reduced. The catalysts conditioned by the present invention cause minimal conversion of SO2 to SO3. The platinum group metal compositions soluble or dispersible in the diesel fuel and are added in amounts effective to provide concentrations of the metal in the fuel of less than 1 part per million (ppm).

Abstract translation: 本发明提供一种使用燃料添加剂的方法，其长期持续的催化活性并且不需要将SO 2转化为SO 3，从而改善了通过氧化催化剂的操作。 通过燃烧包含燃烧以释放活性形式的催化剂金属的铂族金属组合物的燃料来连续选择性催化直通催化剂载体。 该方法的有效性归因于通过催化剂改善发动机的燃烧和在燃烧期间释放的活性催化剂金属处理催化氧化剂，使得在排气系统中，颗粒的可溶性有机部分和气体的水平 未燃碳氢化合物和一氧化碳显着降低。 由本发明调理的催化剂导致SO 2转化为最少的SO 3。 铂族金属组合物可溶于或分散在柴油中，并以有效提供燃料中金属浓度小于百万分之1（ppm）的量加入。

Abstract: Platinum group metal fuel additives are effective in fuel environments which make the exclusion of water impractical. The fuels additives comprise a platinum group metal compound and a water-functional composition selected from the group consisting of lipophilic emulsifiers, lipophilic organic compounds in which water is miscible and mixtures of these. The additives are preferably effective in fuel compositions having water contents of at least about 0.01 % water by weight.

Abstract: The invention presented relates to a method for reducing the emission of nitrogen oxides from a diesel engine without significant loss of fuel efficiency and without significant increases in carbon monoxide and hydrocarbon emissions. The method involves preparing a diesel engine such that the injection timing thereof is set at a point sufficient to obtain reductions in the nitrogen oxides emissions from the engine; and firing the diesel engine with a diesel fuel having admixed therein an additive which comprises a fuel soluble organometallic platinum group metal coordination composition.

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 fue l of less than 1 part per million (ppm). Lithium and/or sodium compositions can be used in amounts effective to reduce the tr ap regeneration temperature, e.g. concentrations to provide about 1 to 100 ppm lithium metal, and/or 1 to 30 ppm sodium metal .

Abstract: La invencion proporciona un método que emplea un aditivo de combustible para mejorar la operacion de un catalizador de oxidacion de paso sobre largos períodos de tiempo con actividad catalítica continua y sin la indeseable conversion de SO2 a SO3. Un soporte de catalizador de paso se cataliza continuamente de manera selectiva mediante la combustion de un combustible que contiene una composicion metálica del grupo platino que se quema para liberar el metal catalizador en forma activa. La efectividad del proceso se atribuye a una combustion mejorada en el motor mediante el catalizador y el tratamiento del oxidante catalítico con el metal catalítico activo liberado durante la combustion de tal manera que, en el sistema de descarga, la fraccion orgánica soluble de las partículas y los niveles de hidrocarburos no quemados gaseosos y el monoxido de carbono se reducen significativamente. Los catalizadores condicionados por la presente invencion provocan una mínima conversion de SO2 a SO3. Las composiciones metálicas del grupo platino solubles o dispersable en el combustible diesel y se añaden en cantidades efectivas para proporcionar concentraciones del metal en el combustible de menos de 1 parte por millon (ppm).
