Catalytic converter for exhaust gases
A catalytic converter for use in the exhaust systems of internal combustion engines and a method of assembly are described. A housing including a tubular shell has a differentially hardened, annular fibrous lining to resiliently support, insulate, and secure a monolithic type catalyst element. The ends of the tubular shell extend beyond the fibrous lining, which in turn extends beyond the upstream and downstream ends of the catalyst element. The ends of the shell and the ends of the fibrous lining are angularly deformed inwardly to protect the corners of the catalyst, to minimize gas impingement on the fibrous material, and to mechanically retain the catalyst in position. The method includes the steps of inserting the monolithic catalyst into the shell with the annular resilient lining in place around the periphery of the catalyst, bending the ends of both the shell and liner over the ends of the catalyst and subsequently attaching inlet and outlet conduits to the ends of the shell.
