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.
