PROTECTING
THE ENVIRONMENT
The devices for curtailing petrol engine
emissions are the following:
❒ three-way catalytic converter;
❒ Lambda sensor;
❒ fuel evaporation system.
In addition, do not let the engine run, even
for a test, with one or more spark plugs
disconnected.
The devices for curtailing diesel fuel en-
gine emissions are the following:
❒ oxidising catalytic converter;
❒ exhaust gas recirculation system
(E.G.R.).
❒ diesel particulate filter (DPF)
DIESEL PARTICULATE
FILTER (DPF) (for 1.3 Multijet
versions 90 HP)
The Diesel Particulate Filter is a mechan-
ical filter, integral with the exhaust system,
that physically traps particulates present
in the exhaust gases of Diesel engines.
The diesel particular filter has been adopt-
ed to eliminate almost totally particulates
in compliance with current / future law
regulations.
During normal use of the vehicle, the en-
gine control unit records a set of data (e.g.:
travel time, type of route, temperatures,
etc.) and it will then calculate how much
particulates has been trapped by the filter.
Since this filter physically traps particulates,
it shall be cleaned (reclaimed) at regular
intervals by burning carbon particles.
Reclaiming procedure is controlled auto-
matically by the engine control unit ac-
cording to the filter conditions and the
conditions of use of the vehicle.
During normal service the
catalyst reaches high tem-
peratures. Do not therefore park the
car over inflammable materials (grass,
dry leaves, pine needles, etc.): fire
hazard.
WARNING
During reclaiming the following phenom-
ena could take place: idling slight increase,
fan activation, slight smoke increase, high
exhaust temperatures. These situations
shall not be considered as faults and they
do not affect vehicle performance and en-
vironment.
If the dedicated message is displayed, re-
fer to paragraph “Warning lights and mes-
sages”.
