Catalytic Converter: Description and Operation
Converter Types
CAUTION: Prolonged operation with a misfiring or flooded engine may cause the converter to overheat. This could cause damage either to
the catalyst itself or the operating vehicle and possible personal injury.
NOTICE: When jacking or lifting vehicle from frame side rails, be certain lift pads do not contact catalytic converter otherwise damage to
converter may result.
SYSTEM DESCRIPTION
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.
The converter allows for a faster chemical reaction to take place and although it enters into the chemical reaction, it remains unchanged, ready to repeat
the process.
