INTRODUCTION
The Fiat Ducato Natural Power version
features two fuel systems, a primary one
for natural gas (methane) and an emer-
gency petrol alternative.
The methane multipoint
injection system
This is an original product from Fiat’s re-
search in the field of alternative fuels that
comes from close co-operation with im-
portant 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 driveability, exhaust emissions
and consumption.
Using the methane multipoint injection
system the engine offers the same driving
conditions as running on petrol.
Fiat Ducato Natural Power has been de-
signed to run on methane. Petrol func-
tioning is restricted to situations where
the user has not managed to fill up on
methane prior to having entirely run out.
Engine performance has been opti-
mised to run on methane. When
running on petrol, performance is
limited to guaranteeing the reaching
of the nearest petrol station.
Selecting the type of fuel supply
The Fiat Ducato Natural Power version is
configured to normally run on methane.
When the methane is running out and the
pressure in the canister is close to the cor-
rect operating limit, the system automat-
ically switches to petrol operation.
Fiat Ducato Natural Power is not
equipped with a manual METHANE/
PETROL switch selector, and as such the
change between the two fuel types is on-
ly made by the engine control ECU, in a
fully automatic manner.
For this reason there always needs
to be petrol in the tank.
