System and Method for Mitigating the potential for the formation of deposits of urea in an Exhaust System to environmental conditions during Cold Engine

摘要

A device and Method for catalytic reduction of NOx in gaseous products of combustion process before the entry into the atmosphere.The particulate and gaseous products of combustion process flow radially through a Particulate Filter Element of radial Flow (24) which is effective to retain particles, and then are directed axially through a collector (26).A Nozzle (30) introduces an editor in an axial end of the collector to the Drag of the axial flow through the collector in a direction away from the Injector. The Flow out of the Manifold is directed through a SCR Catalyst (40) which produces the catalytic reduction of NOx.
