Patent ID: 6923943

Claim:
An exhaust catalytic converter/muffler consisting of a unit of dual functionality of purifying and muffling exhaust gasses, said unit consisting of: a metallic housing in form of a square or rectangular tube; and a plurality of at least two folded, perforated metallic baffles affixed within said tube; wherein each baffle is coated with catalytic material and positioned so that their apexes form a V shape pointing towards the end of the tube; wherein each baffle contains perforations consisting of slots being oriented parallel to the fold-line of the apex on half of the baffle and perpendicular to the fold-line of the other half of the baffle; the slots having flaps extending outwardly for deflecting gasses traveling through the perforations in said baffles, thereby imparting a swirling motion to the passing gasses; wherein each subsequent baffle is rotated 180 degrees relative to the one preceding it, allowing the gasses traveling through the tube to encounter the flaps of the slots being oriented either parallel or perpendicular to the fold-line of the apex until the gasses reach the end of the tube.
