SAFETY DEVICES/SOLENOID VALVE
A solenoid valve has been screwed onto each bottle, which cuts off the
natural gas flow towards the engine feed circuit.
The solenoid valve is open when:
❐the switching button is in the “Natural gas” position
❐the pressure inside the bottle is enough for functioning
❐the engine is running
❐the inertia switch has not tripped.
The solenoid valve unit features the following safety devices:
1) Fuse plugnut: in case of anomalous overtemperature (higher than
110°C), this device will fully eliminate any overpressure hazard by
causing the natural gas contained in the bottle to flow outwards as fast
as possible.
2) Excessive flow: this device comes into operation in case of pipe
breakage, by reducing the natural gas outgoing flow to non-hazardous
values. The flow relief valve is placed in such a position that it can
operate even when the solenoid valve body is broken following a
collision.
3) Manual cock: it is positioned upstream the solenoid valve.
It separates the bottle from the natural gas system to allow the
maintenance operations to be carried out.
To turn cock (A) off, rotate clockwise (position 1).
To turn the cock on, rotate counterclockwise (position 2).
4) Non-return valve, positioned on the pipe running from the filling pipe
union, to prevent the natural gas from flowing back.F0E0572m

FUELLING AND FILLING
Person transport version
Petrol .................................................................. litres 38
❐ including a reserve of .................................. litres 5
Natural gas (*)
❐ bottle ................................................................ litres 164
❐ Natural gas (*) ............................ m338.9 (kg 26.49)
(*) Natural gas in standard conditions: 15°C; 1.013 bar; density: 0.680
kg/m3.
IMPORTANT! Please be reminded that when natural
gas is used to fuel the vehicle, the fuel distance may
vary to some extent since it depends on the vehicle
maintenance and driving conditions as well as the
temperature of the gas in the bottle.
In fact, natural gas heats up when it is filled and cools
when the vehicle is running, thus undergoing pressure
variations that reduce the amount of gas that can be
used.ENGINE OIL
IMPORTANT! As regards the engines powered by
alternative fuels (natural gas), a multigrade engine oil
shall be used, which shall feature very high fluidity,
grade: SAE 5W30, specifications ACEA A1-A5 - API SL
and FIAT 9.55535-M1.
Therefore, it is recommended that you use the
SELENIA PERFORMER MULTIPOWER oil.
