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.
