Catalytic Converter: Description and Operation
Oxidation Catalyst
The oxidation catalytic converter contains a platinum coated, ceramic, honeycombed structure. Through a chemical reaction, the platinum oxidizes
HC and CO and converts them to carbon dioxide and water vapor. Effective operation of this type of catalyst requires temperatures of 600° F or
higher as well as an adequate supply of oxygen in the exhaust system. Oxidation catalysts will normally "light off" (start oxidation) within two
minutes after the first start of a cold engine.
