• Contaminants in the exhaust gas (HC, CO, NO
X
) are purified by oxidization and deoxidization while passing
through the catalytic converter.
— Oxidization process
• Noxious HC (hydrocarbon) and CO (carbon monoxide) are bonded to oxygen which is converted to
non-noxious carbon dioxide and water.

+ HC + CO → CO

— Deoxidization process
• Noxious NO

(nitrogen oxide) is converted to non-noxious nitrogen and oxygen. A part of the oxygen
generated at this time is used in the oxidization process.
