Summary:

Metal supported catalysts, whose early development actually started in the sixties, are used today in a few isolated cases as starter catalysts, retrofit and underfloor catalysts of small dimensions. The new Porsche Carrera 4 is the first production car to use a large main catalytic converter with metal supports. This paper describes the design of this catalyst and the advantages of using the metal supports, especially the increase in power output due to the reduction of exhaust back pressure. Also benefits in catalytic performance could be determined. The major requirement in using large metal supports in production is mechanical sturdiness. In extensive vehicle, test bench and laboratory tests and according to the theoretical calculations, the support with S-design described here has met this requirement. In spite of some still existing disadvantages, both of which can be reduced with further development, the use of metal supported catalytic converters is a serious alternative to the conventional ceramic supported catalyst
