Catalytic Converter: Description and Operation

Three-Way Catalytic Converter:

PURPOSE
Reduces HC, CO and NOx in the exhaust gas.

LOCATION
In the exhaust piping.

OPERATION
When the temperature within the catalyst reaches approximately 600° F a chemical reaction takes place. The chemicals with the catalyst react with the exhaust. The reaction breaks down the pollutants, strips atoms, and converts them to no polluting chemicals H2O (water), CO2 (carbon dioxide) and N2 (nitrogen).

CONSTRUCTION
Closed shell with an inlet and outlet. The converter contains the catalyst elements platinum, rhodium and palladium.
