VERSION WITH
METHANE SYSTEM
(Natural Power)

INTRODUCTION
The Fiat Fiorino Natural Power version
features two fuel systems, one for
petrol and one for natural gas
(methane).
Selecting the type of fuel supply
Fiat Fiorino Natural Power is configured
to run normally on methane gas.
When the methane is running out and
the pressure in the cylinder is close
to the correct operating limit, the
system automatically switches to petrol
operation.
The engine always starts up on petrol,
with automatic switching to methane
when the best conditions are achieved
(engine water temperature, minimum
engine rpm limit) for switching to
methane.
Therefore, there must always be some
petrol in the tank (at least 1/4 full), in
order not to compromise the operation
of the fuel pump.61F0T0199
62F0T0302
33

For this reason there must always
be petrol in the tank.
The petrol/methane switch fig. 63,
amongst the controls in the dashboard,
makes it possible to select petrol
operation. The system does not switch
automatically to methane operation if
the petrol runs out.
IMPORTANT If gas is smelled, switch
from methane operation to petrol
operation and immediately go to a Fiat
Dealership to have the vehicle checked
and possible system faults excluded.
CYLINDERS
The vehicle has two cylinders (total
capacity about 77 litres) located under
the floor and protected by two special
guards.
The cylinders fig. 64 and fig. 65 are the
tank that contains methane in
compressed gaseous state (200 rated
bar at 15 °C).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. 66. 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.63F0T0343
64F0T0345
65F0T0356
34
KNOWING YOUR VEHICLE

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. 67 or
fig. 68.If you want the car to run on petrol,
press the button fig. 69 located
between the controls in the dashboard.
The LED on the button switching on
indicates that the request for switching
has taken place correctly.The actual change to the chosen fuel
system takes place depending on
the vehicle usage conditions to
guarantee switching in absolute safety
and will be confirmed by the
warning
light in the instrument panel display
coming on/going off.
Manual switching of the operating
mode from petrol to methane and
vice versa only occurs if the engine
speed is below 2000 rpm.
In addition, in the case of starting at
outside temperatures of below around
-10°C, the switching times from Petrol
to Methane increase to allow the
pressure regulator/reduction unit to
become warm enough.
IMPORTANT If switching takes place
during acceleration or pick-up, there
may be a brief flat spot (drop in power).

WARNING
31)The Fiat Fiorino Natural Power is
equipped with a high pressure methane
fuel supply system, designed to operate at
a rated pressure of 200 bar. It is dangerous
to stretch the system with higher
pressures. To prevent damage to the
methane system parts when towing or
lifting the vehicle, follow the instructions in
the main handbook in the chapter: "Towing
the vehicle". If there is a problem with the
methane system, only contact a Fiat
Dealership. Do not alter the methane
system configuration or components. They
are designed exclusively for the Fiat
Fiorino Natural Power. The use of other
components or materials could cause
malfunctions and prejudice safety.
32)When oven painting, the cylinders must
be removed from the vehicle and refitted
by a Fiat Dealership. Although the methane
system has numerous safety features, it is
advisable to close the manual tap on the
cylinders every time the vehicle is not
in use for a long period, transported on
other vehicles or moved in an emergency
as a result of a breakdown or accident.
33)If gas is smelt, switch from methane
operation to petrol operation and
immediately go to a Fiat Dealerships to
have the vehicle checked and possible
system faults supply excluded.
WARNING
5)Regardless of the last fuel system used,
at the following engine starting, after the
initial petrol stage, the system will
automatically switch to methane.
6)At the time of the switching request
there will be a metallic noise from the
valves which are pressurising the circuit
(more obvious with the ignition key in
the MAR-ON position). For the switching
logic described above, a delay between the
valve ticking and the switching off of the
instrument panel indication is completely
normal.
7)Do not switch between the two
operating modes whilst starting the engine.
