INTRODUCTION
The Fiat Multipla “Natural power” version features
two fuel feed systems: one for petrol, one for natural
gas.
The two systems are independent from each other;
the natural gas system is of the sequential, timed
Multipoint type.
One single starting system, that is the petrol one, is
available.
What is natural gas?
Natural gas is a mixture of gas used as a primary
power source.
Methane is the main component of natural gas; for this
reason, natural gas is usually reffered to as “methane”
in Italy, even though it contains other hydrocarbons
and inert gases in small amounts.
Natural gas is extracted in a gaseous state and carried
to the place of utilization through gas pipelines;
supplies are abundant and well distributed worldwide.
Methane is a fuel that has a low impact on the
environment as, it significantly reduces the
contribution of exhaust fumes to the greenhouse
effect and pollution.Natural gas Multipoint injection system
This is an original product of the research work
carried out by Fiat in the field of alternative fuel,
realized in close co-operation with qualified suppliers
in the natural gas field.
By matching the natural gas features with highly
sophisticated techniques for electronic petrol engine
control, significant results have been obtained as far as
driveability, exhaust emissions and consumption are
concerned.
The natural gas Multipoint injection system ensures
the same engine driveability features as with petrol
fuelling.
In any case, it should be reminded that, under any
driving condition, the engine power and torque
features are, during natural gas fuelling, reduced by
approximately 10% compared with petrol fuelling.
