Beschreibung
Zusammenfassung:	A method of ammonia production for a selective catalytic reduction system includes producing a first exhaust flow and a second exhaust flow. The first exhaust flow has a higher NOx concentration than the second exhaust flow. The method also includes directing a portion of the second exhaust flow to a reformer. The method further includes combining the portion of the second exhaust flow directed to the reformer with the first exhaust flow upstream of an ammonia-producing catalyst.
