    Abstract: A low-emissions diesel fuel comprises fungible aviation kerosene grade 55, 50–300 ppm detergent, 25–500 ppm lubricity additive and a bimetallic, fuel soluble platinum and cerium fuel borne catalyst (e.g., 0.1–2.0 ppm platinum COD and 5–20 ppm cerium oleate). The fuel can be used as is or in the form of an emulsion. A method of reducing the emissions of pollutants from a diesel engine, comprising running the engine on a fuel as defined. Retarding engine timing can further reduce NOx and the use of a diesel particulate filter and/or diesel oxidation catalyst can provide further reductions in carbon monoxide, unburned hydrocarbons and particulates.

    Abstract: The removal of sulfur oxides (SO.sub.x) and nitrogen oxides (NO.sub.x) from combustion effluents is enhanced by the supplying of reactants in a particular distribution pattern in the gas flow. To achieve the particular distribution pattern and to avoid impingement of the reactant on the heat exchanger tubes of the combustor, an elongated injection lance comprising c cooling jacket and plural spaced injections ports is employed. The cooling jacket protects the reactant supply to the injection ports from the high temperatures of the combustion gases.
