DIESEL FUEL CONTAINING RARE EARTH METAL AND OXYGENATED COMPOUNDS

摘要

The invention relates to a fuel additive concentrate comprising a major amount of a cerium salt of an acid selected from the group consisting of carboxylic acids and cycloalkyl carboxylic acids having from 3 to 25 carbon atoms, and a monoalkyl or dialkyl ether of diethylene glycol or a derivative thereof having from about 5 to 16 carbon atoms and a minor amount of a diesel fuel composition boiling in the range of about 350.degree.F (175.degree.C) to 750.degree.F (400.degree.C). When added to a diesel fuel, the additive has been found to reduce particulate emissions from an engine using the fuel.
