Foreword
This guide has been written for those who are committed, every day to saving lives, following accidents involving one or
more vehicles. In particular, it is for the Fire Service and for those whose task it is to remove these vehicles.
We do not presume to teach any of those who already do a wonderful job: our objective is simply to make interventions
easier, helping to speed up processes and, maybe even, help save more human lives.
For this reason, the content indicates, for example, the layout of the tank or the cylinders on diesel, CNG and LNG vehicles,
with reference made to safety regulations, operator behaviour in the event of a gas leak or fire, together with information
regarding access to the vehicles or trailer release.
Of course we fully understand that all accidents are different, in size and seriousness and that it can be difficult to establish
guide lines which can be the same for all eventualities but we do hope that this manual can be of some help.
In moments of intense emotion where, paradoxically, calm is essential, it is our hope that this guide will clarify any doubts
and may be an effective "tool", easy to refer to, able to assist rescuers and providing important information in a clear and
concise way.

Manual closure for maintenance and shut-off
Solenoid valve(3) controlled by ignition key.
The solenoid valve is one-way and does not shut off the flow into the cylinder; thus the cylinders must be charged when the solen-
oid valves are not powered.
Safety functions:
●Flow limiter (2) that intervenes in the event of a sudden change in pressure, effectively limiting the outward flow of gas
from the cylinders; for example if a pipe breaks. After the downstream leak has been eliminated, and the pressure equilibrium
has been re-established, the outflow limiter valve in its closed position still allows a small flow of gas to enable resetting the
device.

2 Discharge device with

3 Solenoid valve
4 Check valve
5 Gas inlet union
●fusible plug locked in the discharge device (2) that melts at 110±10°C.
The safety circuit, composed of the fusible plug, allows the gas to be discharged safely in case of fire on the vehicle, preventing cylin-
der explosions due to overpressure.
This circuit communicates directly with the exterior independently of: outflow limiter valve, manual valve and solenoid valve.
Upstream of the interceptor solenoid valve there is a manual tap valve which performs the same function as the previous solenoid
valve, but is operated manually; its presence is important in case of any maintenance of the system, when it becomes necessary to
close the cylinders.
The solenoid valve fitted on the first cylinder is connected to the filling valve and is equipped with a check valve.
The function of this valve is to prevent the flow of CNG from the cylinder to the filling valve and is moreover another safety ele-
ment as it is in addition to the valve in the filling valve.
The valve opens due to the pressure of the gas during filling.
●Flow limiter: if a pipe bursts or the valve assembly breaks (for example due to an accident), CNG escapes (gas leak) and
the flow limiter trips to limit the flow of CNG to approximately 0.5% of the setting for normal engine operation, eliminating
the danger deriving from the presence of a considerable flow rate of CNG. The flow limiter is positioned in the threaded
shank of the valve assembly so as to remain inside the cylinder, ensuring operation even in the event of the solenoid valve
body breaking as a result of an accident.

Cylinders description
Solenoid valve on cylinder
226155 Figure 12
1 Cylinder 2 Solenoid valve
The CNG, compressed at a pressure of 200 bar, is stored in some cylinders, positioned in the chassis frame and protected by spe-
cial sheet metal guards.
The cylinders, connected together in series, are filled via a filling valve equipped with a check valve.
A second check valve is included in the solenoid valve fitted on the first cylinder connected to the filling union.
The function of the check valves is to prevent the gas escaping outwards and the dispenser being removed from the filling valve
after refilling or a pipe bursting.

9 Filter
10 Discharge chamber
The pressure reducer decreases the CNG pressure from the value
in the cylinders to the electric injector supply value (6 ±1 bar), in all
engine operating conditions.
The pressure reduction takes place in a single stage in which the
pressure is reduced from 200 to 6 bar
Since the CNG drops sharply in temperature because it expands due
to the jump in pressure, the engine cooling circuit has a branch that
allows the engine coolant to heat the pressure reducer assembly so
as to avoid any trouble due to the change in temperature, such as the
formation of condensation or even ice that could block the pressure
reducer.
It is equipped with a CNG shut-off solenoid valve and a CNG pres-
sure sensor.

Note The pressure reducer must be positioned with the solenoid valve (1) facing upwards.
A maximum tilt of 15°from the vertical axis is permitted.
CNG shut-off solenoid valve
The CNG shut-off solenoid valve is normally closed.
This allows CNG to flow only when it is energized.
It is powered via the ignition key through a specific contactor and is connected directly to ground.
With the solenoid valve powered (ignition key set to MAR), CNG can flow towards the pressure reducer valve and then towards
the electro-injectors.

8 Ball
This switch (1) trips in case of accident, cutting off the supply to the
solenoid valves both on the cylinders and on the pressure reducer,
consequently cutting off the gas supply.
A steel ball (8) fitted into a tapered housing is normally kept secured
by the attraction force of an adjacent magnet.
Under specific acceleration loads, the ball is released from the mag-
netic retainer (6) and gradually comes out of the tapered support
with an upward movement, according to the cone angle.
Above the ball (8) is a quick-connect mechanism that generates the
normally closed (N.C.) electric circuit.
The mechanism changes position when it is hit by the ball, from N.C.
(normally closed) circuit to N.O. (normally open) circuit, thus cutting
off the solenoid valve supply ground circuit.
In case of impact in any of the three orthogonal directions, the switch
will operate above the 12 g peak (acceleration values), equivalent to
an impact at 25 km/h.
The inertia switch (1) can be restored by pushing the button (3)
protected by a flexible cover (2) (that is also used to protect against
any foreign bodies).
The switch (1) is located in the engine compartment.
