CATALYTIC CONVERTER APPARATUS

摘要

A catalytic converter apparatus for use in an exhaust system of an internal combustion engine includes a housing having a gas inlet and a gas outlet, and at least one catalytic substrate element disposed in the housing. The at least one substrate element is divided into a plurality of zones or sections, the zones at least partially separated from one another to inhibit heat flow. The zones can be at least partially separated with walls. The walls can include insulating material for reducing the mobility of heat radially outwardly. Each of the zones defines a generally separate flow passage connecting the inlet and outlet in fluid communication. The apparatus can heat more rapidly from a cold start compared with conventional catalytic converters.

1. A catalytic converter apparatus for use in an exhaust system of an internal combustion engine, the apparatus comprising:
a housing including a gas inlet and a gas outlet; a substrate element arranged in the housing, the substrate element carrying catalytic material and having a plurality of zones, each of the zones defining a generally separate flow passage, the flow passages, at one end of the substrate, merging together interiorly of the housing to connect to the inlet and, at the other end of the substrate, merging together interiorly of the housing to connect to the outlet; and at least one wall at least partially separating the zones from one another, the at least one wall being adapted to inhibit heat flow between the zones and being generally impervious to gas flow between the zones.
