Catalytic Converter



Description & Operation

The catalytic converter is a muffler-like container built into the exhaust system. The catalyst element consists of individual pellets or a honeycomb monolithic substrate coated with a noble metal such as platinum, palladium, rhodium or a combination. When the exhaust gases come into contact with the catalyst, it changes residual HC, CO and NOx in the exhaust gas into CO 2 , H 2 O and N, before the exhaust gas is discharged into the atmosphere.
