Embodiment Construction

[0032] In general, the present invention describes an inlet surface that prevents and / or eliminates clogging of a surface of a fluid channel at which the inlet surface is provided. The inlet surface includes a distinct outer end surface disposed on the end of the base. An end face disposed on the base may prevent and / or eliminate surface clogging on the inlet surface. For example, the inlet surface helps prevent and / or eliminate deposits of carbonaceous fouling and / or unburned hydrocarbons on the inlet surface from engine emissions such as internal combustion engine exhaust.

[0033] In one of the embodiments, the inlet surface of the fluid channel comprises a substrate having a porous structure configured to allow fluid to flow through said substrate. Outer end structures are provided on the porous structure of the substrate and at the ends of the substrate. The end structures are provided to prevent and / or eliminate surface clogging on the ends of the substrate and the por...

Abstract

An inlet face for an aftertreatment device that prevents and / or eliminates face- plugging for a passageway where the inlet face is disposed. The inlet face includes a particular end surface disposed on an outer surface at the end of a substrate. The end surface includes at least one of a three-dimensional topographical configuration disposed at the end of the substrate, a chemical coating applied on the end of the substrate, or both a three-dimensional topographical configuration disposed on the end of the substrate and a chemical coating applied on the three-dimensional topographical configuration. As one example, the inlet face can be helpful in preventing carbonaceous fouling, which can result from engine exhaust material, such as carbon soot and other engine exhaust by-products.

Description

[0001] priority information [0002] This application is a PCT international application filed by Cummins Filtration IP, Inc., claiming the title of the invention filed on July 2, 2007, entitled "Preventing surface Blockage," U.S. Patent Application No. 11 / 772,619, which is incorporated in its entirety into the present application. technical field [0003] The present invention discloses an inlet surface that prevents and / or eliminates surface clogging in a fluid channel. By way of example, the present invention provides an inlet surface that is particularly suitable for use in a variety of aftertreatment devices to prevent and / or eliminate carbonaceous fouling and / or unburned hydrocarbons deposited on the inlet surfaces of these aftertreatment devices Deposits of compounds, carbonaceous fouling and / or deposits of unburned hydrocarbons originate, for example, from exhaust emissions from internal combustion engines. Thus, the present invention provides an inlet surface that ...
