Catalytic Converter: Description and Operation
The purpose of the three way catalytic converter is to simultaneously reduce "HC" (Hydrocarbon), "CO" (Carbon Monoxide) and "NOx" (Oxides
of Nitrogen) emission in the exhaust manifold.
Two basic materials are incorporated in the three way catalytic converter, platinum (Pt) and Rhodium (Rh). A thin film of their mixture is applied
onto the honeycomb or porous ceramic of an oval shaped carrier.
