ABSTRACT:
The present invention provides an auxiliary catalytic converter having a back pressure relief device being disposed after the main catalytic converter or after the muffler system which further reduces vehicle exhaust emissions from exhaust emission systems and that will meet the more stringent emission requirements of state and federal government regulations. The auxiliary catalytic converter includes a ceramic or steel housing of relatively small size, having a diameter in the range of 1 inch to 8 inches and a length of 4 inches to 11 inches. The housing includes a matrix core of catalytic layered materials which react with the gaseous exhaust emission pollutants, such as NO.sub.x, NHMC, HC, and CO. These pollutants are further reduced and oxidized by the auxiliary catalytic converter using typical catalytic materials of platinum, palladium, rhodium, or the like contained within the honeycombed or meshed layers of the matrix core. The auxiliary catalytic converter is lodged within the interior of the exhaust piping. The auxiliary catalytic converter is held in place by mounting clamps, mounting screws, mounting brackets, or the like.
