Catalytic Converter: Description and Operation

Three-Way Catalytic Converter:

PURPOSE
The two catalytic converters are emission control devices added to the exhaust system to reduce hydrocarbons (HC), carbon monoxide (CO) and oxides of nitrogen (NOx) emissions.

OPERATION
The catalytic material promotes burning (oxidation) of the pollutants as the gases pass through the converter. The gases are transformed into non-polluting vapors and gases; water (H20) and carbon dioxide (CO2).

CONSTRUCTION
The converters incorporate a honeycomb mesh coated with catalysts.
