ABSTRACT:
A preferred catalytic converter structure suitable for treating automotive exhaust gases comprises a wound corrugated metal foil and gas passages defined by facing foil surfaces of adjacent turns, wherein one surface carries platinum catalyst and the facing surface separately carries palladium catalyst for concurrently treating gases flowing therethrough. A preferred method for manufacturing said structure comprises applying platinum catalyst and palladium catalyst to distinct halves in length of both foil surfaces, which halves border along a transverse axis, and winding the foil about the axis to bring the surfaces into facing relationship.
