FIAT PUNTO NATURAL POWER
Passive safety
The Fiat Punto 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 Punto Natural Power version has
the same active safety features as the oth-
er versions.
The Fiat Punto Natural Pow-
er version is equipped with a
high pressure methane system de-
signed to run at 200 bar.
It is dangerous to force the system
with higher pressures. When towing
or lifting the car, 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 car”.
If there is a problem with the
methane system, only go to a Fiat
Dealer.
Do not alter the methane system con-
figuration or components; they are
designed exclusively for the Fiat Pun-
to Natural Power. The use of other
components or materials could cause
malfunctions and reduce safety.In the case of painting in an
oven, the canisters should be
removed from the vehicle and refit-
ted later by a Fiat Dealer. Although
the methane system has numerous
safety features, it is advisable to close
the manual taps for the canisters
every time the car 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.
