Catalytic Converter: Description and Operation

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.
