Abstract
A system for reducing NO.sub.x gases found in the exhaust stream of the internal combustion engine is provided which includes an internal combustion engine having associated therewith a means for supplying fuel and oxygen to the engine, a manifold system for directing or channeling the exhaust gases from the engine, and a NO.sub.x reducing catalyst assembly communicating with the manifold which includes a housing having a NO.sub.x reducing catalytic structure of apertured thin metal foil positioned therein which comprises a durable, chromium containing corrosion resistant nickel base substrate having metallurgically bonded thereto, on at least one surface, an effective amount of a NO.sub.x reducing catalyst selected from the group consisting of iron, nickel, cobalt, copper, manganese and mixtures thereof.
