The methane, stored in the canisters at
high pressure, flows through a
dedicated pipe to reach the pressure
regulator/reduction unit which supplies
the 4 methane injectors at low pressure
(about 6 bar).
Cylinder capacity: about 13 kg. The
amount of methane depends on the
outside temperature, the supply
pressure, the quality of the gas and the
type of refuelling system. Total cylinder
volume about 77 litres.

The level of methane in the cylinders is
indicated by the four vertical bars

near the word CNG on the instrument
panel display fig. 68. When the residual
amount of methane is lower than 1/5
of the capacity of the cylinders, the first
level and the edges of the bars of the
other 3 levels flash until the next
methane refuelling. A specific message
will appear on the display in addition
to an acoustic warning.
