LOW-EMISSIONS DIESEL FUEL EMULSIONS

摘要

A low-emissions diesel fuel comprises fungible aviation kerosene emulsified with from 1 to 30 % water, and preferably contains 50-300 ppm detergent and 25-500 ppm lubricity additive. Improved results can be achieved by also employing a fuel-soluble platinium group compound, such as 0.1-2.0 ppm platinium COD and a fuel-soluble cerium compound, such as 5-20 ppm cerium oleate. A method of reducing the emissions of pollutants from a diesel engine, comprising running the engine on a fuel as defined. The method is improved by also employing another pollution-reducing technique selected from timing changes, exhaust gas recirculation, oxidation catalysts, lean NOx catalysts and particulate filters for enhanced emissions control,
