Passive safety
The Fiat Ducato Natural Power version
has the same passive safety features as the
other versions.
In particular, the location and mountings
of the canisters have been designed to
pass the impact tests in accordance with
Fiat safety standards. The flow of methane
coming out of the canisters is governed by
a solenoid 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 (fuse pad that allows
the methane to drain off if the tempera-
ture exceeds 110 °C) and a pressure cal-
ibration device that intervenes if the pres-
sure 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 (inertia switch or
fuel cut off switch).
Active safety
The Fiat Ducato Natural Power version
has the same active safety features as the
other versions.
The Fiat Ducato Natural
Power version is equipped
with a high pressure methane system
designed to run at 200 bar.
It is dangerous to force the system
with higher pressures. When towing
or lifting the vehicle, the instructions
in this booklet at the end of the chap-
ter should be followed in order to pre-
vent damage to the methane system
parts: ‘Towing the vehicle’.
If there is a problem with the
methane system, only go to an au-
thorised Fiat Dealer.
Do not alter the methane system con-
figuration or components; they are
designed exclusively for the Fiat
Ducato Natural Power. The use of
other components or materials may
lead to malfunctioning and compro-
mise safety.
When oven painting, the
canisters should be removed
from the vehicle and later carefully
refitted by a Fiat Dealer. Although the
methane system has numerous safe-
ty features, it is advisable to close the
manual taps for the canisters every
time the vehicle is not in use for a
long period, transported on other ve-
hicles or moved in an emergency as a
result of a breakdown or accident.
