The catalytic converter plays a major role in the emission control system. The catalytic converter operates as a gas reactor.

The catalyst material inside the catalytic converter consists of a ceramic substrate.
The catalytic converter is designed to provide a long life. No maintenance is necessary for the catalytic converter.
