The methane, stored in the cylinders at
high pressure, flows through a
dedicated pipe to reach the pressure
regulator/reduction unit which supplies
the two methane injectors at low
pressure (about 9 bar).
Cylinder certification
The methane cylinders are certified in
accordance with ECE Regulation no.
110.
The cylinders must be inspected, in
accordance with ECE Regulation
Procedure no. 110, every 4 years from
the car registration date or in
accordance with specific regulations in
individual countries.
The plates provided by the Dealership
with the on board documentation
contain the date for the first inspection
of the cylinders. Methane refuelling
stations are not authorised to refill the
cylinders when the inspection date has
expired.
IMPORTANT If the vehicle has been
registered in a country other than Italy,
the certification data, identification
and inspection procedures for
the methane cylinders should conform
to the legislation in that country. In
any case, remember that the life of the
cylinders is 20 years from the
production date as set out in ECE
Regulation no. 110.

This engine normally runs on methane
except during starting, when it runs
on petrol.
The button A fig. 43 (petrol/methane
switch) allows you to select running on
petrol or methane.
To guarantee switching in full safety, the
actual change to the chosen fuel
system takes place depending on the
car usage conditions; it may not
therefore be immediate.
Switching is confirmed by the green
warning light
on the instrument panel
turning on/off.
In addition, when starting at outside
temperatures below approximately
–10°C, the switching times from petrol
to methane increase to allow the
pressure regulator/reduction unit to
heat up.
If the methane has run out, switching to
petrol takes place automatically. In this
case, the four bars of the digital gauge
turns off and the green warning light
on the instrument panel turns on.
REFUELLING
Methane
Capacity: about 12 kg. The total
volume of cylinders is about 72 litres.
