Catalytic Converter: Description and Operation
Front Portion Of Exhaust System
PURPOSE
The catalytic converter is an emission control device added to the exhaust system to effectively reduce the levels of carbon monoxide,
hydrocarbons, and in some cases oxides of nitrogen, exiting the tailpipe.
This device sometimes requires the use of heat shields, due to its high operating temperatures. The heat shields are necessary to protect chassis
components, passenger compartment, and other areas from heat related damage.
OPERATION
The converter contains a honeycomb network coated with catalytic material containing platinum, palladium and rhodium. The catalytic material
promotes burning or oxidation of the pollutants as the exhaust gases pass through the converter.
A small diameter fuel tank filler neck is used on catalytic converter equipped vehicles to prevent the use of leaded fuel pump nozzles.
LOCATION
The catalytic converters are located in the exhaust system.
