Catalytic Converter: Description and Operation

TWC 

-

The TWC cleans exhaust gases by oxidizing unburned: carbon monoxide (CO) hydrocarbons (HO) nitrogen oxides (NOx).

-

90-95% of these harmful substances are converted into innocuous: water (H20) carbon dioxide (CO2) nitrogen (N2)

-

The active surface area of the unit is about 43,000 m2 and the noble metal content of about 3.5 grammes platinum/rhodium.

NOTE:  Lead in fuel will damage the TWC, quickly making it unserviceable.
