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.

(*) The amount of methane depends on
the outside temperature, the supply pres-
sure, the quality of the gas and the type of
refuelling system. Total cylinder volume
about 77 litres.IMPORTANT Please note that, when us-
ing a fuel like methane, the range can vary
greatly as it depends on the temperature
of the gas in the cylinder as well as on the
vehicle driving and maintenance condi-
tions.Methane heats up during filling and cools
down during driving, undergoing changes
in pressure that reduce the quantity that
can be used.
It should also be pointed out that whilst
the vehicle is being run in (up to around
3,000 km) fuel consumption may be high-
er than the figures given. Recommended fuels
