ABSTRACT:
A catalytic converter selectively controllable between a radial flow mode, wherein exhaust gas is caused to radially flow across the catalyst thereof, and a by-pass mode, wherein exhaust gas passes axially therethrough. The catalytic converter includes a selectively perforated tube, a catalytic monolith composed of a series of alternating herringbone corrugation patterned foil sheets having a noble (precious) metal catalytic material applied to the surface thereof wherein each of the foil sheets has a central hole whereat is situated the tube, a valve for selectively occluding the tube, and a clam-shell enclosure. The herringbone corrugation pattern provides a plurality of radial passageways. When the valve is in its closed position the tube is in a closed state, wherein the exhaust gas entering the tube upstream of the catalytic monolith is caused to pass through the passageways until emerging at the outer periphery of the catalytic monolith. The enclosure captures the emerging exhaust gas, which travels between the enclosure and the outer periphery of the catalytic monolith and thereupon enters a snorkel space downstream of both the catalytic monolith and the valve, whereupon the exhaust gas re-enters the tube.
