Catalytic Devices - Triumph TR7 Owner's Manual

EMISSION AND EVAPORATIVE LOSS CONTROL SYSTEMS
CATALYTIC DEVICES
The following precautions apply to catalytic devices:-
(1) In order to maintain the efficiency of the emission
control system
it
is essential to use UNLEADED
gasoline only; this fuel also minimises spark plug
fouling thereby sustaining engine performance.
(2) DO NOT tamper with the engine settings. they have
been established to ensure that the vehicle will comply
with stringent exhaust emission regulations. Incorrect
engine settings could cause unusually high catalytic
converter temperatures and thus result in damage to
the converter and vehicle. If adjustment to the settings
is considered necessary, this should be performed by a
Rover Triumph Dealer or other qualified facility,
(3) A correctly tuned engine optimises exhaust emiSSions,
performance and fuel economy and it is recommended
that the vehicle is maintained as outlined under the
MAINTENANCE SUMMARY of this handbook.
(4) DO NOT continue to operate the vehicle if any engine
malfunction is evident, malfunctions should be rectified
immediately. For instance, misfire, loss of engine
performance or engine run-on may lead to unusually
high catalytic converter temperatures and may result in
damage to the converter and car.
(5) NEVER leave the vehicle unattended with the engine
running.
(6) The use of a catalytic converter increases exhaust
system temperatures, (particularly under engine
malfunction!. therefore do not operate or park the
vehicle in areas where combustible materials such as
dry grass or leaves may come into contact with the
exhaust system
(7) The vehicle is designed for normal road use. Below are
examples of abuse which could damage the catalytic
converter and ~ar and may lead to a dangerous
condition due to excessively high catalytic converter
temperatures.
(a) Competition use
(b) Off roadway use
(c) Excessive engine revolutions
(d) Overloading the vehicle
(e) Excessive towing loads
(f) Switching off the engine and coasting
In
gear
(8) DO NOT run the engine with either a spark plug lead
disconnected or a spark plug removed. DO NOT use
any device that requires an insert into a spark plug hole
in order to generate air pressure. (e.g. tyre pump, paint
spray attachment. etc.). as this could result in catalytic
converter damage.
(9)
DO NOT push or tow the vehicle to start it. thiS could
damage the catalytic converter It IS recommended thaI
jumper leads are used.
(10) Heavy impact on the converter casing must be avoided
as it contains ceramic material which is easily damaged.
