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.
