ABSTRACT:
A metal foil substrate catalytic converter for use in the exhaust system of an internal combustion engine, having corrugated metal foil sheets secured together in a stack so that a plurality of axially extending fluid flow paths are defined therebetween. Disposed at predetermined intervals throughout the stack are foil retainer sheets having integral foil tabs extending outwardly from the side edges and folded about the outer side surface of the substrate to form a segmented foil skin thereabout. The segmented foil skin may be welded continuously along its length to secure the foil sheets in a unitary catalyst substrate and to provide a weld surface for attachment of the catalyst substrate directly to the converter canister wall.
