Abstract
Abstract A housing assembly includes a catalyst carrier body having a given cross section, a given maximum length and a given maximum width. A housing has an interior and a cross section being larger than the given cross section. The housing has an approximately rectangular opening formed therein with a length being greater than the given maximum length and a width being greater than the given maximum width. A flat or curved retaining plate is secured to the catalyst carrier body and has a greater length and a greater width than the opening for closing the housing like a lid with the catalyst carrier body protruding into the interior of the housing. A device is provided on the housing and/or the retaining plate for fastening the housing and the retaining plate to each other.
