Catalytic converter

All models covered in this manual are fitted with a three-way catalytic converter.

The catalytic converter is similar in appearance to a small muffler. Its honeycombed ceramic core contains hundreds of tiny passages whose surfaces are coated with a thin layer of precious metal(s). The internal construction of the catalytic converter is designed to maximize the surface area of the catalyst-coated ceramic and promote the chemical reactions that convert harmful compounds into nitrogen, carbon dioxide, water, and heat.

Under normal conditions the catalytic converter does not require replacement.
