Catalytic Converter: Description and Operation

  Three-Way Catalytic Converter

PURPOSE

Reduces exhaust emissions.

OPERATION

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 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).

CONSTRUCTION

The converter incorporates a honeycomb mesh coated with three catalysts.
