VERSION WITH
METHANE SYSTEM
(Natural Power)
41) 42) 43)
8) 9) 10)
INTRODUCTION
The Fiat Doblò Natural Power version
features two fuel supply systems,
one for petrol and one for natural gas
(methane).
Selecting the type of fuel supply
Fiat Doblò Natural Power is configured
to run normally on methane.
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.
For this reason there must always
be petrol in the tank.The petrol/methane switch fig. 87,
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.
METHANE CYLINDERS
The vehicle is provided with 4 cylinders
with a capacity of 95 litres; for the
Cargo Maxi version (long wheelbase), a
5
thcylinder is available as an optional,
increasing the capacity to 130 litres.The cylinders are all located under the
floor and protected by special guards.
The cylinders fig. 88, fig. 89 and fig.
90 are the tank that contains methane
in compressed gaseous state (200
rated bar at 15 °C).
Canister capacity:
- Short wheelbase versions: approx.
16.15 kg
- Short wheelbase versions: approx.
22.1 kg.
The amount of methane depends on
the outside temperature, the supply
pressure, the quality of the gas and the
type of refuelling system. Overall
cylinder volume approximately 95 litres
(short wheelbase versions) and 130
litres (long wheelbase versions).

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 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. 91. 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:
for Euro 5 versions: on the
instrument panel display, first level plus
edges of the bars of the other three
levels keep blinking and the indicator
lights up near the CNG icon.
for Euro 6 versions: on the display,
all the empty segments stop flashing
and then the
indicator near the CNG
icon turns on.
If you specifically wish to run on petrol,
press the dedicated button fig. 87
located on the central tunnel. 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.
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).

KNOWING YOUR VEHICLE

WARNING
41)The Fiat Doblò Natural Power version is
equipped with a high pressure methane
system designed to run 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 Qubo Natural
Power. The use of other components or
materials could cause malfunctions and
prejudice safety.
42)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.
43)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
8)Regardless of the last fuel system used,
at the following engine starting, after the
initial petrol stage, the system will
automatically switch to methane.
9)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.
10)Do not switch between the two
operating modes whilst starting the engine.
