Emission Control System - Porsche 928 1980 Owner's Manual

An Important Word of Caution
on the Emission Control System
in Your Car
Your Porsche is equipped with a Lambda
Emission Control System. The major com-
ponents of this system are three way
catalytic converter and oxygen sensor.
These components are designed to burn
carbon monoxide, hydrocarbons and oxides
of nitrogen in the exhaust gas. Normal
operating temperature of the exhaust sys-
tem will not cause any heat related problems
if you maintain and use your car properly.
Lack of necessary maintainance, maladjust-
ment of the fuel system or ignition timing, or
improper use of the car may cause overheat-
ing problems. This can lead to damage to the
catalytic converter and other components of
your car.
Therefore:
• Have your car maintained properly in
accordance with the service recommen-
dations of the Warranty & Maintenance
booklet.
• Do not alter or remove any component of
the Emission Control System unless ap-
proved by the manufacturer.
• Do not alter or remove any device, such
as heat shields, switches, valves, which
are designed to protect your car and the
environment.
72
• Do not leave your car with engine idling
unattended after starting. Should warn-
ing lights come on to indicate improper
operation, they would go unheeded. Ex-
tended idling produces heat which could
result in damage to emission control and
other components in your car.
• Do not continue to operate your vehicle if
you detect engine misfire or other unusual
operating conditions.
· Do not park your car over combustible
material, including grass or leaves, which
may come into contact with the hot ex-
haust system.
Catalytic Converter
Immediate damage to the catalytic conver-
ter will result if you turn the ignition off while
your car is moving, or if you try to push-start
the car, because under these conditions un-
burned fuel can reach the catalytic conver-
ter, which will make it ineffective as an anti-
pollutant device.
Undercoating
Do not apply additional undercoating on or
near the exhaust manifold, exhaust pipes,
catalytic converter or heat shields. The
substance used for undercoating could
overheat during driving and cause a fire.
In the interest of clean air
Pollution of our environment is of increasing
concern to all of us. We urge you to join us
in our efforts for cleaner air in controlling the
pollutants emitted from the automobile.
Porsche has long recognized its responsi-
bilities not only toward its customers but
also toward the public in general. We have
developed an emission control system that
controls or reduces those parts of the emis-
sion that can be harmful to our environment.
Your Porsche is equipped with such a sys-
tem. On the following page we explain how
the Porsche emission control system works,
and what you can do to keep it in working
order.
Your new car is warranted under the terms
and conditions set forth in the Warranty &
Maintenance booklet.
You, as the owner of the vehicle, have the
responsibility to provide regular mainten-
ance service for the vehicle and to keep a
record of all maintenance work performed.
To facilitate record keeping, have the service
performed by authorized Porsche dealers.
They have Porsche trained mechanics and
special tools to provide fast, efficient service.
