Definitions

  • a substrate retainer for an exhaust processor having an outer shell including an external surface facing away from a central axis and an internal surface facing toward the central axis and defining an interior region and a substrate including a first end, a second end spaced apart from the first end along the central axis, and an outer surface extending between the first end and the second end sop that the substrate is positioned in the interior region of the outer shell so that the outer surface of the substrate is spaced apart from the internal surface of the outer shell by a distance.
  • the substrate retainer includes an intumescent material and a wire mesh coupled to the intumescent material.
  • the intumescent material has a first portion and a second portion spaced apart from the first portion.
  • the substrate support is designed and arranged to be positioned between the outer shell and the substrate so that the first portion is positioned adjacent to the first end of the substrate and the second portion is positioned adjacent to the second end of the substrate.
  • Fig. 3 is a cross-sectional view of the substrate retainer having the corrugated wire mesh support embedded in the intumescent mat support showing ridges and troughs of the corrugated wire mesh support extending to the surfaces of the mat support;
  • retaining element 22 including sheet 66 of wire mesh support 60 embedded in intumescent mat support 62 is wrapped around substrate 14.
  • First edge 59 and second edge 61 of corrugated mesh support 60 are joined together by spot welds 78 as shown, for example in Fig. 2, or by some other appropriate joining method such as soldering.
  • Third edge 63 of wire mesh support 60 is positioned adjacent one of outlet end 36 and inlet end 34 of substrate 14 and fourth edge 65 of wire mesh 60 is positioned adjacent the other of inlet end 34 and outlet end 36 of substrate 14.
  • retaining element 22 extends substantially the entire axial length 42 of substrate 14.
  • Shell 12 is then wrapped around the retaining element 22 compressing retaining element 22 between the outer surface 38 of substrate 14 and the internal surface 30 of the shell 12.

Abstract

L'invention concerne un système de traitement (10) de gaz d'échappement possédant un axe central (32, 40), une enveloppe extérieure (12), un substrat (14) et un support (22) de substrat. L'enveloppe extérieure (12) comporte une surface intérieure (30) définissant une zone intérieure. Le substrat (14) présente une première extrémité (34), une deuxième extrémité (36) et une surface extérieure (38) s'étendant entre la première et la deuxième extrémités (34, 36). Ce substrat (14) est placé dans la zone intérieure de l'enveloppe intérieure (12), de sorte que la surface extérieure (38) de ce substrat (14) est déplacée d'une distance par rapport à la surface intérieure (30) de l'enveloppe extérieure (12). Le support (22) du substrat est constitué par un matériau intumescent (62) et par un treillis de fils (60) accouplé au matériau intumescent (62) et est placé de façon à s'étendre à plat entre l'enveloppe extérieure (12) et le substrat (14). Ce matériau intumescent (62) comprend une première partie contiguë à la première extrémité (34) du substrat (14) et une deuxième partie contiguë à la deuxième extrémité (36) du substrat (14).
