CATAL YTICCONVERTER
The catalytic converter is an emission. control device added
to
the exhaust
system to reduce exhaust
gas
pollutants. The converter contains a
ceramic material coated with
nobIemetal catalysts. With the catalytic
converter,
the
gasoline engine can·be tuned for improved fuel economy
and driveability.
The catalytic
converter requires the use
of
unleaded gasoline.
Unleaded gasoline
is
used to reduce combustion chamber deposits,
exhaust system corrosion, and to prevent lead contamination of the
catalysL
If
you
use leaded gasoline, the catalytic converter
will
lose its
effectiveness (or emission control.
. .
To help prevent damage:
1.
Keep your engine properly tuned. Engine malfunctions involving
the electrical, carburetion or ignition systems
may , result
in
unusually high converter and exhaust system temperatures. Do not
keep
driving
youfcar
if you
de~ect
engine misfire,. noticeable loss
of
performance, or other unusual operating conditions. Instead, have it
serviced promptly. A properly tuned engine will help avoid
malfunctions that could damage the converter. It will also help
maintain good emission
control
and gasoline economy. See the
Maintenance
Schedule folder for information on inspecting and
maintaining the engine, exhaust system, and other components.
