REDUCTION OF FOULING IN AFTER TREATMENT COMPONENTS
摘要
<p>A device and method for influencing exhaust gas flow downstream of a turbocharger turbine and upstream of after treatment components prevents doser tip fouling by using a passive exhaust flow control surface comprising ridges protruding into the exhaust gas flow conduit. The ridges are disposed parallel to each other, and perpendicular to the direction of gas flow. In one embodiment, a funnel is disposed in the conduit, downstream of the ridges, to further direct the exhaust gas flow more precisely towards a HC doser tip.</p>
