Abstract:
1. A catalytic converter apparatus for use in an exhaust system of an internal combustion engine, the apparatus comprising: a) a catalytic converter housing including a single gas inlet and a single gas outlet; b) a substrate element arranged in the housing, the substrate element carrying catalytic material and defining a plurality of zones, each of the zones defining a generally separate flow passage connecting the inlet and the outlet in fluid communication; and c) at least one wail 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 wherein the substrate element is a unitary substrate, each of the zones is a honeycomb substrate and the honeycomb substrate wall thickness is a constant applicable to all zones.
