Catalytic Converter: Description and Operation

Exhaust System:

Final filtering of the exhaust gases is accomplished by a three way catalytic converter. The converter contains a compound of platinum and rhodium.
If the fuel system maintains an optimum air fuel ratio, with oxidation of CO content and HC, the catalytic converter reduces the emission of NOx. The exhaust emitted by the car to the atmosphere consists mainly of CO2, H2O, and pure nitrogen.
