Catalytic Converter: Description and Operation

  Three-Way Catalytic Converter

The catalytic converter is an emission control device added to the exhaust system to reduce hydrocarbons (HC), carbon monoxide (CO) and oxides
of nitrogen (NOx) emissions. The converter incorporates a honeycomb mesh coated with three catalysts. The catalytic material promotes burning
(oxidation) of the pollutants as the gases pass through the converter. The gases are transformed into non-polluting gases H20 (water) and CO2
(carbon dioxide).
