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 18):
A method for aftertreatment of engine-out exhaust from an internal combustion engine flowing through an exhaust flow path having an entrance through which untreated engine-out exhaust enters and an exit through which treated exhaust exits, the method comprising:\n in a mixing zone, mixing anhydrous solid reductant capable of forming ammonia and unenhanced DEF to create enhanced DEF; injecting enhanced DEF upstream of a main SCR catalyst to entrain with exhaust flow for enabling catalytic reduction of some NOx in exhaust flow across the catalytic material of the main SCR catalyst.
