FIAT FIORINO/QUBO NATURAL POWER
Passive safety
The Fiat Fiorino Natural Power has the
same passive safety features as the other
versions.
In particular, the cylinder location and
mountings are designed to pass the impact
tests in accordance with the Fiat safety
standards. The flow of methane coming
out of the cylinders is governed by a so-
lenoid valve that is only open during
methane operation.
The solenoid valve unit includes protec-
tion against excess flows (if the high pres-
sure system breaks, the flow of methane
is restricted to values that are not dan-
gerous), overheating (a fuse pad that al-
lows the methane to drain off if the tem-
perature exceeds 110 °C) and a pressure
calibration device that intervenes if the
pressure goes above 300 bar ensuring the
methane escapes in a controlled manner
and as quickly as possible.
The solenoid valve is connected to the Fire
Protection System (fuel cut-off system).
Active safety
The Fiat Fiorino Natural Power has the
same active safety features as the other
versions.
The Fiat Fiorino/Qubo Natu-
ral Power version is equipped
with a high pressure methane system
designed to run at a rated pressure of
200 bar.
It is dangerous to force the system
with higher pressures. When towing
or lifting the vehicle, follow the in-
structions in the main handbook in
the chapter on Towing to prevent
damage to the methane system parts.
In case of problems with the methane
system, only contact a Fiat Dealership.
Do not alter the methane system con-
figuration or components; they are
designed exclusively for the Fiat Fior-
ino/Qubo Natural Power. The use of
other components or materials may
lead to malfunctioning and compro-
mise safety.When oven painting, the
cylinders should be removed
from the vehicle and later carefully
refitted by a Fiat Dealership. Al-
though the methane system has nu-
merous safety features, it is advisable
to close the manual taps on the cylin-
ders every time the vehicle is not in
use for a long period, transported on
other vehicles or moved in an emer-
gency as a result of a breakdown or
accident.

FIAT FIORINO/QUBO NATURAL POWER3) Excess flow,intervenes if the pipes
break and limits the flow of methane ex-
iting to non dangerous levels.
The flow restrictor valve is located to al-
low it to operate even if the solenoid valve
casing is broken due to an impact.
4) Manual tap,it is located upstream of
the solenoid valve.
SOLENOID
VALVES/SAFETY
DEVICES
The solenoid valves Fig. 5and Fig. 6are
bolted directly onto the methane cylinders
with the main function of interrupting the
flow of methane to the supply circuit.
The solenoid valves are open when:
❒the switching button is in the methane
position;
❒the pressure in the cylinder is sufficient
for operation;
❒the engine is running.
The solenoid valve assembly is equipped
with the following safety devices:
1) Fuse pad,in the case of overheating
(temperature above 110 °C), it totally
eliminates the danger of excess pressure
making the methane in the cylinder flow
out as quickly as possible in a controlled
manner.
2) Mechanical excess pressure device
(Burt Disk),in the case of excess pres-
sure (above 330 bar), it ensures that the
methane escapes as quickly as possible in
a controlled manner.It separates the cylinder from the methane
system to allow maintenance operations.
The taps are accessible from outside the
vehicle and are located, in the case of the
lengthwise middle cylinder, at the rear of
the cylinder and, in the case of the trans-
verse rear cylinder, towards the wheel
right side.
To close the taps D-Fig.7: turn the knob
in the direction (1) shown by the arrow
(clockwise
OFF).
To open the taps D-Fig.7: turn the knob
in the direction (2) shown by the arrow
(anticlockwise
ON).
5) Check valve,this prevents the
methane from flowing back to the filler.

FUEL CONSUMPTION
N.B.The trip computer data concerning
range, average consumption and instan-
taneous consumption are not available for
this version.
The fuel consumption figures, given in the
table below, are determined on the basis
of the homologation tests laid down by
specific European Directives.The procedures below are followed for
measuring consumption:
– urban cycle: begins with cold starting,
followed by driving simulating the use of
the vehicle in town;
– extra-urban cycle: driving that simulates
using the vehicle out of town with fre-
quent acceleration in all gears; the speed
varies from 0 to 120 km/h;
– combined consumption: determined
through a weighting of about 37% of the
urban cycle and 63% of the extra-urban
cycle.IMPORTANT The type of route, traffic
conditions, weather conditions, driving
style, state of the vehicle in general, trim
level/equipment/
accessories, use of the climate control, ve-
hicle load, presence of a roof rack and oth-
er situations that adversely affect the aero-
dynamics, may lead to consumption figures
that differ from those measured (see
Saving fuel” in the Starting and
driving” chapter in the booklet).
