Abstract:
1. An exhaust treatment device for vehicles comprising: an inner housing having an inlet and an outlet defining a longitudinal direction and having a thermally-activated exhaust treatment device therein chosen to reduce emissions from the exhaust of a combustion engine as the exhaust passes from the inlet to the outlet; an outer housing enclosing the inner housing but characteristically not contacting the inner housing, the outer housing including an inlet and an outlet that align with the inlet and outlet of the inner housing, the inner and outer housings including walls forming a sealed cavity around the inner housing, the cavity having a vacuum drawn therein; and a support that supports the inner housing in the outer housing, the support including a radially-extending body and including a foot that engages at least one of the inner and outer housings, the foot including an insulative material different from the body, the insulative material being chosen to minimize conductance of heat.
