Catalytic Converter System Description

The warm up three way catalytic converter (WU-TWC) and the under-floor three way catalytic converter (under-floor TWC) convert hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) in the exhaust gas to carbon dioxide (CO 2), nitrogen (N 2), and water vapor. The WU-TWC is attached directly under the cylinder head into which the exhaust manifold is integrated.
