Catalytic Converter: Description and Operation

Three-Way Catalytic Converter

PURPOSE

Reduces exhaust emissions.

LOCATION

In the exhaust flow.

OPERATION and CONSTRUCTION

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).

The converter contains the catalyst elements platinum, rhodium and palladium which promote oxidation and reduction reactions at high
temperatures. Emissions are converted into carbon dioxide, water vapor and nitrogen.
