A support system (120) for a fragile substrate (118) of an exhaust gas treatment device (110) includes a microporous, inorganic insulating layer (212, 322), which directly or indirectly engages at least a portion of the fragile substrate; and a flexible fibrous mounting mat (213, 323) which directly or indirectly engages at least a portion of said fragile substrate. The support system may support the fragile substrate of a catalytic converter, a diesel particulate trap filter, a selective catalyst reduction unit, or a NOx trap.
L'invention concerne un système de support (120) pour un substrat fragile (118) d'un dispositif de traitement de gaz d'échappement. Le système comprend une couche isolante microporeuse et inorganique (212, 322), venant directement ou indirectement en contact avec une partie du substrat fragile ; et un tapis de montage fibreux et flexible (213, 323) qui vient directement ou indirectement en contact avec au moins une partie dudit substrat fragile. Le système de support peut maintenir le substrat fragile d'un pot catalytique, d'un filtre à particules diesel, d'une unité sélective de réduction de catalyseur ou d'un piège à NOx.
