27 Claims

1. A pollution control device comprising:

a housing;

a pollution control element disposed within the housing; and

a mounting system disposed in a gap between the pollution control element and the housing for positioning the pollution control element within the housing and for absorbing mechanical and thermal shock, the mounting system comprising:

an intumescent mounting mat, and

at least one resilient, flexible, fibrous non-intumescent insert that, independent of the intumescent mounting mat, can accommodate changes in the gap as the pollution control device is cycled between high and low temperatures,

wherein the intumescent mat has a peripheral edge and the insert has a peripheral edge, and the peripheral edge of the intumescent mounting mat and the peripheral edge of the insert are juxtaposed and directly facing each other, and the insert has a greater resiliency than the intumescent mounting mat.
