초록

The present invention relates to a process for reducing nitrogen oxides emissions from a diesel engine, which comprises preparing an emulsion of an aqueous urea solution in diesel fuel, and supplying said emulsion to a diesel engine for combusting therein, whereby combustion of the emulsion leads to a reduction in the nitrogen oxides emissions from the diesel engine when compared with combustion of diesel fuel alone.
