Three Way Catalytic (TWC) Converter: Description and Operation
Federal
Three-Way Catalytic Converter
PURPOSE
To reduce exhaust emissions of NOx, HC, and CO.
LOCATION
In the exhaust tubing.
OPERATION
A three-way catalytic converter is used downstream of the exhaust manifold to reduce oxides of nitrogen (NOx) and oxidize hydrocarbons (HC)
and carbon monoxide (CO). Emissions are converted into carbon dioxide, water vapor and nitrogen.
CONSTRUCTION
The converter contains the catalyst elements platinum, rhodium and palladium which promote oxidation and reduction reactions at high
temperatures.
