LPG MULTIPOINT
INJECTION SYSTEM
This product is produced by working
closely with qualified suppliers in the
LPG sector.
The injection system used on the car is
an efficient system in terms of engine
performance and is based on the
injection of LPG in a gaseous state.
In this system with four injectors, one
for each intake manifold, the fuel is
injected directly into the engine heat
transfer ducts, thereby metering the
LPG very precisely improving
combustion and, at the same time,
excluding any possibility of flame return.
By adapting the electronic control
technology of petrol engines to meet
LPG specifications, significant results in
terms of driveability and controlling
exhaust emissions have been obtained.
When running on LPG the engine has
almost the same torque and power
features as when running on petrol:
consequently, the car performance can
be compared.
SELECTION OF THE FUEL
SUPPLY TYPE
The car is configured for running
independently on either petrol or LPG.
The engine always starts up on petrol,
with automatic switching to LPG whenthe best conditions are achieved
(engine water temperature, minimum
engine rpm limit) for switching to LPG.
In addition, it is advisable to periodically
use up the petrol in the tank (until the
reserve warning light comes on) in order
to ensure that the petrol does not
become old and possibly deteriorate.
The petrol/LPG switch fig. 69 allows
drivers to select petrol or LPG
operation.
IMPORTANT There must therefore
always be some petrol in the tank to
protect the petrol pump and to
guarantee temporary switching from
LPG to petrol operation, if high
performance is required.PASSIVE SAFETY/ACTIVE
SAFETY
Passive safety
The car has the same passive safety
specifications as other versions. In
particular, the mountings of the tank
(located in the space-saver wheel
housing) have been designed to comply
with the Fiat safety standards for impact
tests.
When running on LPG, the flow of gas
(in a liquid state) leaving the tank
passes through the specific piping to
the pressure regulator unit, where there
is a safety solenoid valve that stops the
flow of LPG when the ignition key is
removed or when the driver selects a
fuel change (decision to run on petrol).
Together with the regulator solenoid
valve, a second solenoid valve, in the
tank, closes the LPG piping at the tank
outlet.
The two solenoid valves are connected
to the fuel cut-off system (Fire
Protection System).
The LPG tank complies with the current
legal regulations of the countries where
the car is sold.
Active safety
The car has the same active safety
specifications as other versions.
