SUBSTRATE RETAINER FOR EXHAUST PROCESSOR

摘要

An exhaust processor (10) having a central axis (32, 40), an outer shell (12), a substrate (14), and a substrate support (22) is disclosed. The outer shell (12) has an internal surface (30) defining an interior region. The substrate (14) has a first end (34), a second end (36), and an outer surface (38) extending between the first and second ends (34, 36). The substrate (14) is positioned in the interior region of the outer shell (12) so that the outer surface (38) of the substrate (14) is displaced from the internal surface (30) of the outer shell (12) by a distance. The substrate support (22) includes an intumescent material (62) and a wire mesh (60) coupled to the intumescent material (62) and is positioned to lie between the outer shell (12) and the substrate (14). The intumescent material (62) includes a first portion adjacent to the first end (34) of the substrate (14) and a second portion adjacent to the second end (36) of the substrate (14).
