Abstract
A catalytic converter body having a jacket tube, a plurality of non-nestable foil leaves having inner and outer ends defining a leaf length, the outer ends being connected to the jacket tube and radiating inward to provide flow passages generally transverse to the leaf length, and a pliant central core joined to the inner ends of the radiating foil leaves. The catalytic converter body has a natural frequency of between 10 and 100 hertz. The catalytic converter is formed by assembling a plurality of non-nestable foil leaves by interconnecting proximal ends of the foil leaves to provide a continuous flexible strip of overlapping foil leaves in which opposite the distal ends of the leaves extend freely. The strip of foil leaves is then formed into a pliant central core permitting movement of the inner ends relative to each other, and the leaves are arranged to lie in curved paths radiating outwardly from the interconnected proximal ends away from a central area to provide flow passage cells generally parallel to the leaf ends. Thereafter, the distal ends of the leaves are connected to a jacket tube.
