FIAT PUNTO 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 the phased, sequential multipoint type
with special injectors.LPG Multipoint injection system
This product is produced in strict collab-
oration with prestigious suppliers in the
LPG sector.
The injection system used on the car is an
efficient system in terms of engine per-
formance 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 re-
turn.
By adapting the electronic control tech-
nology of petrol engines to meet the spec-
ifications of LPG, it has been possible to
achieve important results in terms of dri-
veability and controlling exhaust emissions.
Engines running on LPG have almost the
same torque/power specifications as when
running on petrol and, as a result, the per-
formance of the car is also comparable. What is LPG?
LPG (the abbreviation of liquefied petro-
leum gas) is a mixture of gas used as an
economical and safe primary energy
source.
Its main components are: propane gas and
butane gas mixed.
These gases are a product of petroleum
refinement and are also present naturally
in oil fields and methane-producing de-
posits.
In its natural state this mixture is in a
gaseous state but, as the pressure in-
creases, 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.
