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 reducing diesel fuel engine
emissions are the following:
❒ oxidising catalytic converter;
❒ exhaust gas recirculation system
(E.G.R.);
❒ diesel particulate filter (DPF)
92
DPF (DIESEL
PARTICULATE FILTER)
(for 1.3 Multijet 90 HP - 1.3
Multijet 95 HP versions)
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 adopted to
eliminate almost totally particulates in
compliance with current / future law reg-
ulations.
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 particulate,
it should be regenerated (cleaned) at reg-
ular intervals by burning carbon particles.
The regeneration procedure is controlled
automatically by the engine management
control unit according to the filter condi-
tions and vehicle use conditions.
During the regeneration procedure, the
following situations may occur: limited in-
crease of idle speed, activation of electric
fan, limited increase of smoke, high tem-
peratures at the exhaust.
These are not faults; they do not impair
vehicle performance or damage the envi-
ronment. If the dedicated message is dis-
played, refer to section "Warning lights
and messages".
WARNING
The catalytic converter de-
velops high temperature dur-
ing operation. Do not park
on grass, dry leaves, pine needles or
other flammable material: fire risk.
