Patent ·
OSTI ID:6538439
A catalytic converter for removing noxious pollutants from exhaust gases particularly emitted from an automobile internal combustion engine comprises a housing having a pair of longitudinally spaced catalyst containers mounted therein between inlet and outlet. The housing is constituted by a top housing shell and a bottom housing shell positioned one above the other with respective flanges of the top and bottom housing shells joined together. Each of the catalyst containers is similarly constituted by an upper retainer plate and a lower retainer plate positioned one above the other with respective flanges of the upper and lower retainer plates joined together. The overlapped flanges of the upper and lower retainer plates for each catalyst container are sandwiched between the flanges of the top and bottom housing. A secondary air supply pipe is supported by the housing and projects into the intermediate chamber between the catalyst containers within the housing through the joint of the top and bottom housing shells.
