Catalytic Converter: Description and Operation

Catalytic Converters Description

CAUTION: The catalytic converter requires the use of unleaded fuel only, or damage to the catalyst will result.

The catalytic converters are emission control devices added to the exhaust system to reduce pollutants from the exhaust pipes. The three-way catalyst has coatings which contain palladium, platinum and rhodium, which simultaneously lower the levels of HC, CO and NOx.
