초록

The present invention relates to a process for reducing nitrogen oxides emissions from a diesel engine, which comprises preparing an emulsion of water in diesel fuel which contains a catalytically effective amount of catalyst composition and a lubricity additive, 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.

청구항

A process for reducing nitrogen oxides emissions from a vehicular diesel engine comprising forming an emulsion of water in diesel fuel which comprises up to about 70% water by weight, further comprising a catalytically effective amount of a catalyst composition and a lubricity additive, and supplying said emulsion to a vehicular diesel engine to be combusted 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.
