Introduction to vehicle gas (Bi-
Fuel)
*
Cars with Bi-Fuel engines can be driven on
either vehicle gas or petrol. Vehicle gas can be
biogas or natural gas, or a mixture of the two.
Vehicle gas is also called CNG (Compressed
Natural Gas).
Methane is the main component in vehicle gas. In
natural gas, the methane content varies between
85% and 98%. In biogas, the content is almost
100%.
The tanks for vehicle gas are mounted under the
floor in the cargo area and do not affect the nor-
mal petrol tank.
The system is tested in the same way as for pet-
rol cars. The system is closed which means that
leaks are avoided during filling, for example. The
gas tanks are protected and are made to with-
stand a collision. The gas is lighter than air, non-
toxic and has a higher ignition temperature than
petrol and diesel. The risk of fire or explosions in
the event of traffic accidents is therefore lower
than with petrol and diesel.
The tank is equipped with a safety valve that
allows the gas to evacuate from the tank in the
event of abnormally high pressures. This valve
ensures that the tank cannot explode.
WARNING
In the event of an accident, the vehicle must
be inspected and approved by an authorised
Volvo workshop before it may be used again.
Always notify the emergency services on site
that the vehicle is equipped with a CNG-sys-
tem.
WARNING
Smoking and naked flames are prohibited
during refuelling, service and repair work. In
the event of a possible fire, leave the vehicle
immediately and stand a safe distance away.
Do not under any circumstances disassemble
or adjust the system or its component parts
yourself. Carrying out such acts entails risk of
serious personal injury. All service and repair
work must therefore, for safety reasons, only
be carried out by a trained mechanic - an
authorized Volvo workshop is recommended.
WARNING
If you smell gas in or around the vehicle,
switch over to petrol immediately and have
the vehicle checked by the nearest trained
mechanics.
If the car is placed in a spray/paint curing
booth with a drying temperature higher than
60 °C the system pressure must not exceed
50 bar, check that the CNG tank is almost
empty for this.
