FIAT BRAVO LPG
KNOWING YOUR CAR
INTRODUCTION
The LPG version of the car features two
fuel systems, one for petrol and one for
LPG.
Like the petrol system, the LPG system
is timed, sequential multipoint type with
special injectors.LPG MULTIPOINT
INJECTION SYSTEM
This product is produced by working clo-
sely with qualified suppliers in the LPG sec-
tor. 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.
This improves combustion and, at the sa-
me time, excludes any possibility of back-
draught.
By adapting the electronic control tech-
nology of petrol engines to meet the spe-
cifications of LPG, it has been possible to
achieve significant results in terms of dri-
veability and controlling exhaust emissions.
Engines running on LPG have almost the sa-
me torque/power specifications as when
running on petrol and, as a result, the
performance of the car is also comparable.
The system operates at tem-
peratures are between −20 °C
and 100°C.
WHAT IS LPG?
LPG (which stands for “liquefied petro-
leum gas”) is a gas mixture used as an eco-
nomical and safe primary energy source.
Its main components are: propane gas and
butane gas mixed in various proportions.
These gases are a product of petroleum
refinement and are also present naturally
in oil fields and methane-producing depo-
sits.
In its natural state this mixture is in a ga-
seous state but, as the pressure increa-
ses at ambient temperature, it can easily
be turned into a liquid state.
LPG is a fuel with a low environmental im-
pact because it reduces the pollution pro-
duced by vehicle exhaust gases.
