Catalytic Converter: Description and Operation
Fuel Injected
Exhaust System
The three-way catalytic converter oxidizes CO, HC, and reduces NOx by a chemical reaction. The active materials in the converter are platinum and
rhodium, and the volume is 1600 cc (97.6 ci).
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.
