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.
Cylinder certification
The methane canisters are certified in
accordance with EEC Regulation 110.
The cylinders must be inspected, in
accordance with ECE Regulation
Procedure no. 110, every 4 years
from the vehicle registration date or
in accordance with specific
regulations in individual countries.
PETROL/METHANE
SWITCH
This engine normally runs on methane
except during starting when it runs
on petrol. Switching to methane takes
place automatically and is shown on
the instrument panel display by
switching off the
signal in the display.
Methane fuel reserve
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.
If the methane has run out, switching to
petrol takes place automatically. In this
case the display shows the
icon
just above the CNG wording and all the
bars of the edges for the empty
notches light up constantly, regardless
of the type of supply; see fig. 69 or
fig. 70.
