FIAT PUNTO NATURAL POWER
FUEL SYSTEM (methane)
Dedicated electronic injection for
methane.
Type: Phased, sequential, multipoint.
Injection pressure; about 6 bar.
Stoichiometric metering of the air/
methane gas mixture.
The methane injection system is con-
trolled by the dedicated control unit us-
ing the sensors already on the car, in-
cluding the Lambda sensor for controlling
the fuel metering.
IGNITION
Static advance, electronic, integrated with
the injection.ENGINE COOLING SYSTEM
Engine cooling system with pressure re-
duction unit heating circuit subject to
strong cooling during operation.
PERFORMANCE
Top speed in km/h.
Running on petrol: 162
Running on methane: 156
Modifications or repairs to
the fuel feed system that are
not carried out properly or do not
take the system’s technical specifica-
tions into account can cause mal-
functions leading to the risk of fire.

CAPACITIES

Methane
– Methane (*). . . . . . . . . kg (approx) 13
(*) The amount of methane depends on
the outside temperature, the supply pres-
sure, the quality of the gas and the type
of refuelling system. The total volume of
the canisters is about 84 litres.
IMPORTANT It should be remembered
that when using a fuel such as methane the
range is very variable because as well as
the driving conditions and car maintenance
it also depends on the temperature of the
gas in the canister.
The methane actually heats up during the
refuelling and cools down whilst driving,
undergoing variations in pressure that re-
duce the quantity that can be used.
It should also be pointed out that whilst
the vehicle is being run in (up to around
3000 km) the fuel consumption may be
higher than the figures given.
ENGINE OIL
