Catalytic Converter - Honda 1992 Civic Sedan Owner's Manual

Catalytic Converter

The catalytic converter contains
platinum and rhodium. These
metals serve as catalysts, pro-
moting chemical reactions to con-
vert the exhaust gasses without
affecting the metals. The catalytic
converter is referred to as a three-
way catalyst, since it acts on HC,
CO, and NOx. A replacement unit
must be an original Honda part or
its equivalent.
The catalytic converter must ope-
rate at a high temperature for the
chemical reactions to take place. It
can set on fire any combustible
materials that come near it. Park
your car away from high grass, dry
leaves, or other flammables.
Technical Information
CATALYTIC CONVERTER
A defective catalytic converter
contributes to air pollution, and can
impair your engine's performance.
Follow these guidelines to protect
your car's catalytic converter.
Always use unleaded gasoline.
Even a small amount of leaded
gasoline can contaminate the
catalyst metals, making the
converter ineffective.
Keep the engine tuned-up.
Have your car diagnosed and
repaired if it is misfiring, back-
firing, continuing to run after
you turn off the engine, stalling,
or otherwise not running proper-
ly.
