    Abstract: A method of accelerating the response of an exhaust gas catalyst downstream of an internal combustion engine, the exhaust gas catalyst having at least one metal catalyst carrier body coated with ceramic and catalytically active material having a given response temperature, and the carrier body having at least one subzone, the method includes supplying electric power to the metal catalyst carrier body for direct heating at least in subzones thereof, switching on the current for a period of time at least as early as immediately after the onset of engine operation, and dimensioning the current such that at least subzones of the metal carrier body are heated to the given response temperature at least as early as the exhaust gas reaches the given response temperature. The apparatus for performing the above method includes a main catalyst and an electrically heatable precatalyst disposed upstream of the main catalyst as seen in the flow direction of the exhaust gas. The electrically heated precatalyst carrier body comprises layered metal sheets forming a stack with a plurality of channels through which a fluid can flow, the metal sheets having a thickness of substantially 0.03 to 0.06 mm, insulators for electrically subdividing the catalyst carrier body for forming at least one electric current path through the metal sheets, the current path having an electric resistance of substantially between 0.2 and 2.OMEGA..

    Abstract: A metal catalyst carrier body includes first and second differently corrugated sheet-metal layers being alternatingly wound defining conduits therebetween through which gas flows. The first sheet-metal layer has a simple first corrugation with a periodicity .lambda..sub.1 and an amplitude A.sub.1 primarily determining the size of the conduits. The second sheet-metal layer has a second corrugation with a periodicity .lambda..sub.2 and an amplitude A.sub.2. .lambda..sub.2 =(n..lambda..sub.1)/m, where n=1, 2 or 3; m=1, 2, 3, 4, 5 or 6; and m is .gtoreq.n, forming a multiplicity of periodically recurring oculating contact points having the same direction of curvature. Considering the shape and periodicity of the corrugations, the amplitude A.sub.2 is smaller than the amplitude A.sub.1 by at least an amount sufficient to cause the curvature of the first sheet-metal layer at the contact points to be at least substantially as large as the curvature of the second sheet-metal layer at the contact points.
