FUEL FEED (Natural gas)
Electronic injection specific to the natural gas.
Type: Sequential, timed Multipoint injection.
Injection pressure: approximately 9 bar.
Stoichiometric metering of the air/natural gas mixture.
The natural gas injection system is controlled by a
special control unit by making use of the sensors
previously fitted to the vehicle, including the oxygen
sensor for fuel metering control.
IGNITION
Electronics with static advance integrated with
injection.ENGINE COOLING
Engine cooling system with branching-off to bring hot
fluid in contact with the pressure reducer (which is
subject, during its operation, to heavy cooling).
PERFORMANCE
Maximum speeds in the 5
thgear (kph):
petrol fuelling: 168
natural gas fuelling: 157
Any modification or repair made to the fuel feed system in a wrong way and
without considering the technical features of the system may cause operating
anomalies with a risk of fire.WARNING

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.
