Catalytic Converter: Description and Operation
PURPOSE
To reduce exhaust emissions of NOx, HC, and CO.
LOCATION
In the exhaust tubing.
OPERATION
A three-way catalytic converter is used downstream of the exhaust manifold to reduce oxides of nitrogen (NOx) and oxidize hydrocarbons (HC)
and carbon monoxide (CO). Emissions are converted into carbon dioxide, water vapor and nitrogen.
CONSTRUCTION
A Dual Bed Monolith Catalytic Converter is used in combination with Three Way Catalytic Converter.
Catalytic Types: Three Way (Reduction/Oxidation) Catalyst.
The catalyst coating on the Three Way (reduction) Converter contains platinum and rhodium which lowers the levels of oxide of nitrogen (NOx)
as well as Hydrocarbons (HC) and Carbon Monoxide (CO).
