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. 96,
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.
WARNING 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
5th cylinder 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. 97, fig. 98 and fig. 99
are the tank that contains the methane
in a compressed gaseous state (rated
pressure of 200 bar at 15
°
C).
Canister capacity:
Short wheelbase versions: approx.
16.15 kg
Long 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).
