ABSTRACT:
A catalytic converter for treating engine exhaust gas includes a carrier and a casing housing the carrier. The carrier has opposite first and second ends and is formed therethrough with a plurality of passageways extending from the first to the second end of the carrier. The passageways have opposite first and second ends respectively. The first ends of the passageways are at the first end of the carrier. The second ends of the passageways are at the second end of the carrier. The casing and the second end of the carrier define a space, inside the casing, through which the second ends of the passageways communicate in common. An inlet tube is connected to the casing in such a manner as to directly communicate with a part of the first ends of the passageways, in order to supply the engine exhaust gas thereto. An outlet tube is connected to the casing in such a manner as to directly communicate with another part of the first ends of the passageways. First catalyst is carried on a part of the carrier including the passageways which directly communicate with the inlet tube. Second catalyst is carried on another part of the carrier including the passageways which directly communicate with the outlet tube. The engine exhaust gas flows past the inlet tube, a part of the passageways relating to the first catalyst, the space inside the casing, another part of the passageways relating to the second catalyst, and the outlet tube, in that order.
