FIAT FIORINO/QUBO NATURAL POWER
INTRODUCTION
The Fiat Fiorino/Qubo Natural Power ver-
sion features two fuel systems, one for
petrol and one for natural gas (methane).
The two systems are independent of one
another and the methane one is the timed,
sequential, multipoint type.
The start-up system runs on petrol.
What is natural gas?
Natural gas is a mixture of gases used as
a primary energy source.
Its main component is methane, so for this
reason it is usually known as methane even
though it contains small amounts of other
hydrocarbons and inert gases.
It is extracted in a gaseous state and trans-
ported to where it is used via gas pipelines;
world reserves are plentiful and widely dis-
tributed. Methane is fuel with a environ-
mental low impact because it significantly
reduces the contribution of exhaust gas-
es to the greenhouse effect and pollution.The methane multipoint
injection system
It is an original product from Fiat’s re-
search in the field of alternative fuels, that
comes from close co-operation with ma-
jor suppliers in the methane sector.
By adapting the sophisticated electronic
control technology of petrol engines to
meet the specifications of methane, it has
been possible to achieve important results
in terms of handling, exhaust emissions
and fuel consumption.
With the methane Multipoint injection
system, the engine features the same dri-
veability of a petrol fuelled one.
It should be borne in mind that, under all
driving conditions, methane operation of-
fers engine power and torque specifica-
tions that are 10% lower than with petrol
operation. Petrol operation is there-
fore recommended if a lot of power
is required (e.g. driving uphill with a
laden vehicle, steep hill starts).
Selecting the type of fuel supply
The Fiat Fiorino/Qubo Natural Power is
configured to run normally on methane
gas.When the methane is running out and the
pressure in the cylinder is close to the cor-
rect operating limit, the system automat-
ically switches to petrol operation.
The engine is always started up using
petrol (to keep this fuel supply system ef-
ficient) and, if the engine was running on
petrol before being switched off, when it
is started up again switching to methane
operation will need to be requested man-
ually.
For this reason there must always be
petrol in the tank.
The petrol/methane switch Fig. 1, amongst
the controls in the dashboard, makes it
possible to select petrol operation. The
system does not switch automatically to
methane operation if the petrol runs out.

(*) The amount of methane depends on
the outside temperature, the supply pres-
sure, the quality of the gas and the type of
refuelling system. Total cylinder volume
about 77 litres.IMPORTANT Please note that, when us-
ing a fuel like methane, the range can vary
greatly as it depends on the temperature
of the gas in the cylinder as well as on the
vehicle driving and maintenance condi-
tions.Methane heats up during filling and cools
down during driving, undergoing changes
in pressure that reduce the quantity that
can be used.
It should also be pointed out that whilst
the vehicle is being run in (up to around
3,000 km) fuel consumption may be high-
er than the figures given. Recommended fuels

FUEL CONSUMPTION
N.B.The trip computer data concerning
range, average consumption and instan-
taneous consumption are not available for
this version.
The fuel consumption figures, given in the
table below, are determined on the basis
of the homologation tests laid down by
specific European Directives.The procedures below are followed for
measuring consumption:
– urban cycle: begins with cold starting,
followed by driving simulating the use of
the vehicle in town;
– extra-urban cycle: driving that simulates
using the vehicle out of town with fre-
quent acceleration in all gears; the speed
varies from 0 to 120 km/h;
– combined consumption: determined
through a weighting of about 37% of the
urban cycle and 63% of the extra-urban
cycle.IMPORTANT The type of route, traffic
conditions, weather conditions, driving
style, state of the vehicle in general, trim
level/equipment/
accessories, use of the climate control, ve-
hicle load, presence of a roof rack and oth-
er situations that adversely affect the aero-
dynamics, may lead to consumption figures
that differ from those measured (see
Saving fuel” in the Starting and
driving” chapter in the booklet).
