WARNING
46) For connection to the existing
devices supplied in the vehicle
contact a Fiat Dealership to
prevent any problems that could
impair vehicle safety.
PROTECTING THE
ENVIRONMENT
The following devices are used for
reducing petrol fuel engine
emissions:
❒ three-way catalytic converter
(catalytic converter);
❒ oxygen sensors;
❒ evaporation control system.
In addition, do not let the engine
run, even for a test, with one or
more spark plugs disconnected.
The following devices are used for
reducing diesel fuel engine
emissions:
❒ oxidising catalytic converter;
❒ exhaust gas recirculation system
(EGR);
❒ particulate filter (DPF) (for versions/
markets, where provided).
DIESEL PARTICULATE
FILTER (DPF)
(for versions/markets, where
provided)
The Diesel Particulate Filter is a
mechanical filter, integral with the
exhaust system, that physically
traps carbon particles present in the
exhaust gases of diesel engines.
The diesel particulate filter has been
adopted to eliminate almost all
carbon particles in compliance with
current / future legal regulations.
During normal use of the vehicle, the
Powertrain Control Module records
a set of data (travel time, type of
route, temperatures reached etc.)
and calculates how much particulate
has been trapped by the filter.
Since this filter physically traps
particulate, it should be regenerated
(cleaned) at regular intervals by
burning carbon particles. The
regeneration procedure is controlled
automatically by the Powertrain
Control Module according to the
filter conditions and vehicle usage
conditions.
