ABSTRACT:
An exhaust gas converter arrangement includes a common catalyst support with a precatalyst section and a main catalyst section of larger size downstream in the direction of exhaust flow. The common support is made of alternate corrugated and flat sheet metal members wound into cylindrical shape. Between the precatalyst section and the main catalyst section, the support has an intermediate region in which the sheet metal members are formed with apertures to minimize heat conduction between the catalyst sections.
