Catalytic Converter
This is a supplementary device in the exhaust system, designed to clean the remaining dirty exhaust
gases.
This device is mainly a container with a ceramic material insert, designed to let the exhaust gases pass
through channels in the insert. The channel walls are covered by a thin layer of platina-palladium. These
metals act as catalysts, permitting a chemical action to occur without actually taking part in it.
The CO content will increase if the Catalytic Converter is damaged.
Lambda-sond
TM
equipped vehicles use Catalytic Converters containing platinum and rhodium.
Torque catalytic converter mounting bolts
The Catalytic Converter mounting bolts should be torqued every 15,000 miles (25,000 km).
CAUTION:
Vehicles with Catalytic Converter must use unleaded fuel only. Otherwise the Catalytic Converter
will become damaged and ineffective.
