Abstract
An aftertreatment component for use in an exhaust aftertreatment system. The aftertreatment component comprises an aftertreatment substrate and a compressible material. The compressible material may be formed from a plastic thermoset, a rubberized material, or a metal foil which permits for the selective expansion of the substrate within the compressible material, while also reducing cost and manufacturing complexity. In various embodiments, the aftertreatment substrate and the compressible materials may be formed separately and coupled to each other, or they may be formed concurrently via coextrusion.
Claims17
An aftertreatment component for an exhaust gas aftertreatment system, the aftertreatment component comprising:
- a shell;
- a ceramic substrate at least partially positioned within the shell;
- and
- a cylindrical sleeve comprising corrugations, the cylindrical sleeve positioned between the shell and the ceramic substrate such that the corrugations contact the shell and the ceramic substrate, the corrugations being co-extruded with the ceramic substrate or molded with the ceramic substrate;
- wherein the corrugations comprise at least one of a thermoset material, a rubberized material, a plastic material, a thermoplastic material, a polymeric material, a silicone material, an elastomeric material, or a foam material.
