Abstract:
A diesel engine has an exhaust aftertreatment system which has a vanadium SCR catalyst for reducing some NOx in engine-out diesel exhaust and a trap for trapping any sublimated vanadium which may be present in exhaust which has been treated by a diesel oxidation catalyst, a diesel particulate filter, and a main SCR catalyst which are between the vanadium SCR catalyst and the trap.

Claim (Index 1):
A motor vehicle comprising a diesel engine for propelling the vehicle, the diesel engine comprising an exhaust 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 to surrounding atmosphere, the exhaust flow path containing: 1) a vanadium-based SCR catalyst having surfaces containing vanadium-based catalytic material across which engine-out diesel exhaust flows, and a diesel exhaust fluid (DEF) injector for injecting DEF to entrain with engine-out diesel exhaust flow for enabling catalytic reduction of some NOx in engine-out diesel exhaust flow across the vanadium-based catalytic material, 2) a diesel oxidation catalyst (DOC) for treating exhaust flow from the vanadium-based SCR catalyst, 3) a diesel particulate filter (DPF) for treating exhaust flow from the DOC, 4) a main SCR catalyst having surfaces containing catalytic material across which exhaust treated by the DPF flows, and a diesel exhaust fluid (DEF) injector for injecting 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, and 5) a vanadium trap through which exhaust flow from the main catalyst flows for condensing sublimated vanadium-based catalytic material which may be present in the exhaust flow and trapping the condensate to prevent escape of vanadium-based catalytic material into surrounding atmosphere.
