LPG TANK
28)
The car has a (pressurised) tank A fig.
43 for accumulating LPG in a liquid
state. It is ring-shaped and located in
the spare wheel compartment with
suitable protection.
43
The LPG in the tank is always in both a
liquid and gaseous state, in physical
balance between the two stages.
36
The liquid, which cannot be
compressed, dilates by around 0.25%
for each increase in temperature of
one degree. For this reason a suitable
free gap allowing the increase in volume
of the liquid for all expected
temperature increases is guaranteed
(e.g. car parked in the sunshine in
summer), without compromising tank
integrity.
A safety valve has been fitted to this
end, to automatically limit the refilling of
the tank (during refuelling) to a
maximum level of 80% (liquid) of its
total capacity.
LPG tank certification
The LPG tank is certified in accordance
with the regulations in force.
In Italy, the tank has a life of 10 years
starting from the car registration date. If
F0S0533
the vehicle has been registered in a
country other than Italy, the duration
and the testing/inspection procedures
of the LPG tank can vary depending on
the national laws of that country. In all
case, when the time limit for your
country has expired, go to a Fiat Dealer
to have the tank replaced.
The tank identification data are printed
on the tank, under the multivalve unit:
type-approval country identification
and type-approval number;
type of gas for which it is designed
(LPG);
name of tank manufacturer;
tank commissioning pressure (30
bar);
maximum refilling percentage (80%);
tank dimensions;
rated tank capacity in litres;
tank manufacture date (month/year);
tank serial number.
