Catalytic Converter: Description and Operation

  Three-Way Catalytic Converter

PURPOSE AND OPERATION

The catalytic converters (2 on this model) are emission control devices 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).
