FIAT BRAVO LPG
SOLENOID VALVES
AND SAFETY DEVICES
The system has a solenoid valve located
on the pressure reduction unit and a so-
lenoid valve fitted inside the multiple val-
ve assembly on the tank.
The main function of these solenoid val-
ves is to interrupt/allow the flow of LPG
to the supply circuit.
The solenoid valves are open when:
– a request to run on LPG has been made;
– the optimum engine running conditions
are satisfied (engine coolant temperature,
minimum revs level) for running on LPG;
– there is enough LPG in the tank for
operation.The multivalve assembly fitted on the tank
includes:
– a valve that automatically stops the sup-
ply of LPG when the maximum permitted
filling level is reached (80% of the total
tank capacity);
– a flow limiter which, if a pipe is broken,
prevents the complete and sudden escape
of LPG;
– a one-way valve, located on the gas re-
turn pipe in the tank, which prevents LPG
reflux;
– a safety solenoid valve on the LPG sup-
ply which, either permits or prevents the
escape of gas to the pressure reduction
unit; – a manual tap, upstream of the solenoid
valve, that separates the tank from the
LPG system to allow maintenance opera-
tions;
– a fuse pad which, in the event of
overheating (temperature above 120 °C),
totally eliminates the danger of excess
pressure by making the LPG in the tank
flow out as quickly as possible in a con-
trolled manner;
– an analogue gauge showing the level of
LPG in the tank.

(*) The figure already takes into account
the 80% tank filling limit and the residual
fluid required for the pump and the maxi-
mum permitted capacity. In addition,
said figure may vary slightly in diffe-
rent capacities owing to: differences
between network pump supply pres-
sures, pumps with different sup-
ply/stop specifications, tank not com-
pletely in reserve conditions.It should be remembered that when using
a fuel like LPG, the range is very variable
because, in addition to the driving and
maintenance conditions of the car, it also
depends on the different composition of
the gas which may vary, not only seaso-
nally, but also from supplier to supplier.
LPG is, in effect, a composition of gas (bu-
tane and propane) mixed in a way that
may not be standardized.
The Trip Computer’s range is indicative
and refers to petrol operation only.
During LPG operation, the “Instant con-
sumption” and “Average consumption”
readings are not significant, but all other
functions remain valid.
IMPORTANT Only use LPG for mo-
tor vehicles.If, when refuelling with LPG,
the tank is filled with more
than 41litres (with a toleran-
ce of 2 litres in excess), seek as-
sistance immediately from a Fiat Dea-
lership. Periodically (at least once every
six months), it is advisable to let the
LPG in the tank run out and, at the fir-
st refuelling, check that it does not ex-
ceed the maximum capacity.

NOTE In particularly harsh climate con-
ditions, a mixture of 60% PARAFLU
UPand
40% demineralised water is recommen-
ded.
The LPG supply system is
equipped with a “consump-
tion” function linked to the
LED display of LPG level on
the switch; this function activates only
after a consistent variation in fuel level
has been detected. You are therefore
advised to fill up with fuel at the first
LPG refuelling to obtain a more preci-
se indication of the level

FIAT BRAVO LPG
For petrol engines running on LPG, we recommend using the original product formulated specifically for this type of use.
The use of products with specifications below ACEA C3 – SAE 5W-40 could cause damage to the engine not covered by the war-
ranty.SAE 5W-40 ACEA C3 grade wholly synthetic lubricant.
