Catalytic Converter Cautions


l Keep your engine properly tuned. Certain engine malfunctions, particular\
ly involving the electrical,
fuel or ignition systems, may cause unusually high converter temperature\
s. Do not continue to operate
your vehicle it you detect engine misfire, noticeable loss of power or o\
ther unusual operating conditions,
such as engine overheating or backfiring. A properly-tuned engine will h\
elp in avoiding malfunctions
that could damage the Catalytic Converter.

l Remember that tampering with or unauthorized modifications to the engine\
or the vehicle may be
illegal and can cause catalyst or exhaust system overheating. This inclu\
des:
-- Altering fuel injection settings or components.
-- Adjusting ignition timing beyond specified limits.
-- Altering emission system components or location or removing component\
s.
-- Use of leaded fuel.

WARNING: Do not park your car over combustible materials, such as grass \
or leaves, which can
come into contact with the hot exhaust system and cause such materials t\
o ignite under certain wind
and weather conditions.

l Excessive starter cranking (in excess of one continuous minute) with a\
n intermittently firing or
flooded engine, can cause catalyst or exhaust system overheating. This a\
lso applies to lengthy pushing or
towing of vehicle to start (manual transmissions only). Do not attempt\
to start a car with automatic

transmission by pushing or towing .
CAUTION: Unleaded fuel is required for cars with catalytic converter. A \
label on the instrument panel
and rear fender, near the filler inlet, will remind owners and filling s\
tation attendants of this
requirement.
Important! It is unlawful to dispense leaded fuel into any vehicle label\
ed "unleaded gasoline only".

Unleaded Fuel

Each Volvo has a catalytic converter and must use only unleaded gasoline\
(as specified on the
instrument panel and by a label near the filter inlet). U.S. and Canadi\
an regulations require that pumps
delivering unleaded gasoline be labeled "UNLEADED". Only these pumps hav\
e nozzles which fit your
car's filler inlet. It is unlawful to dispense leaded fuel into a vehicl\
e labelled "unleaded gasoline only".

Leaded gasoline damages the catalytic converter and the oxygen sensor sy\
stem. Repeated use of leaded
gasoline will lessen the effectiveness of the emission control system an\
d could result in loss of emission
warranty coverage. State and local vehicle inspection programs will make\
detection of misfueling easier,
possibly resulting in emission test failure for misfueled vehicles.

Octane Rating

Volvo recommends the use of premium unleaded gasoline with an (R+M)/2 \
rating of 91. This is
generally equivalent to a Research Octane Number (RON) of 95 or higher\
.

Deposit Control Gasolines

Volvo recommends the use of gasolines that contain "Deposit Control" add\
itives. These additives are
specially formulated to prevent the build up of certain injector and int\
ake system deposits. Fuels
containing "Deposit Control" additives are usually advertised as contain\
ing them and may have
additional claims to "clean injectors and intake valves" or similar word\
ing.

complete unit.
Replace more frequently if contaminated fuel was introduced into the tan\
k.

Fuel system cap, tank, lines and connections

The ability of the fuel system to control hydrocarbon emissions is depen\
dent largely on a leak-free
system. Check for proper sealing of gasoline filler cap which contains "\
O"-ring type seals. Check all
evaporative hoses in vehicle for tightness. Check fuel lines under vehic\
le. Repair if necessary.

Air cleaner

Replace the air cleaner cartridge every 30,000 miles (48,000 km). The \
cartridge should be replaced more
often when driving under dirty and/or dusty conditions.
The filter cannot be cleaned and should always be replaced with a new on\
e.

Checking and adjusting idle speed

Your Volvo is equipped with an electronically controlled idle speed syst\
em that requires no period
checking or adjustment.

Lamda-sond (oxygen sensor) system

This is an emission control system designed to reduce emissions and impr\
ove fuel economy. An oxygen
sensor monitors the composition of the exhaust gases leaving the engine.\
The exhaust gas analysis is fed
into an electronic unit which continuously influences the amount of fuel\
injected. This adjusts the air-
fuel ratio to provide optimum conditions for combustion and efficient re\
duction of the three major
pollutants (hydrocarbons, carbon monoxide and nitrogen oxides) through\
a 3-way catalytic converter. pg. 67 Servicing

Oxygen Sensor

On the B230F engines, the oxygen sensor (Lambda-sond) is electrically \
heated. The use of a PTC
(Positive Temperature Coefficient) element to heat the Lambda-sond ens\
ures a shorter warm up time
and continuous operation at its working temperature.
This type of Lambda-sond does not require periodic replacement.

Catalytic Converter

This is a supplementary device in the exhaust system, designed to reduce\
exhaust emissions.
This device is mainly a container with a ceramic material insert, design\
ed to let the exhaust gases pass
through channels in the insert. The channel walls are covered by a thin \
layer of platinum and rhodium.
These metals act as catalysts, permitting a chemical action to occur wit\
hout actually taking part in it.
The carbon monoxide content will increase if the Catalytic Converter is \
damaged.
CAUTION:
Vehicles with Catalytic Converter must use unleaded fuel only. Otherwise\
the Catalytic Converter will
become damaged and ineffective.

Torque catalytic converter mounting bolts

The Catalytic Converter mounting bolts should be re-torqued at the 600-1\
,200 mile (1000-2000) km
inspection.
