Abstract:
Unenhanced DEF and anhydrous solid reductant capable of forming ammonia are mixed to create enhanced DEF which is injected into an engine exhaust aftertreatment system which performs selective catalytic reduction (SCR) of engine-out exhaust.

Claim (Index 1):
A motor vehicle propelled by a diesel engine comprising an exhaust aftertreatment system forming an exhaust flow path having an entrance through which engine-out diesel exhaust enters and an exit through which treated diesel exhaust exits,\n the exhaust flow path containing: 1) a diesel oxidation catalyst (DOC) for treating engine-out exhaust, 2) a diesel particulate filter (DPF) for treating exhaust flow from the DOC, and 3) a main SCR catalyst having surfaces containing catalytic material across which exhaust flow from the DPF passes; a diesel exhaust fluid (DEF) storage tank which holds unenhanced DEF; a secondary reductant store which holds anhydrous solid reductant capable of forming ammonia; a mixing zone in which anhydrous solid reductant and unenhanced DEF are mixed to create enhanced DEF; and a DEF injector for injecting enhanced DEF to entrain with exhaust flow from the DPF for enabling catalytic reduction of some NOx in exhaust flow across the catalytic material of the main SCR catalyst.
