Bearing mat for catalyst carrier arrangement in motor vehicle, has recess, where sheeting density within thickness reduction range does not exceed upper sheeting density limit value and does not fall below lower sheeting density limit value

摘要

The mat (18) has a recess with a material thickness reduced in relation to a reference material thickness. A sheeting density within a range of the thickness reduction in an assembled condition of the bearing mat corresponds to a given sheeting density value related to a given ceramic body region and/or housing range. The sheeting density within the range of the thickness reduction in the assembled condition does not exceed an upper sheeting density limit value and does not fall below a lower sheeting density limit value.
