Abstract:
A close-coupled catalytic article, and its use in an exhaust system for internal combustion engines, is disclosed. The close-coupled catalytic article for the treatment of an exhaust gas comprising: an upstream substrate and a downstream substrate, wherein the upstream substrate is spaced apart from the downstream substrate, wherein the upstream substrate comprises a first three-way catalyst (TWC) composition and the downstream substrate comprises a second TWC composition, the first and second TWC compositions each comprising an oxygen storage component (OSC), wherein a loading of the OSC in the downstream substrate is greater than a loading of the OSC in the upstream substrate and is at least 2.2 g/in3.
