DIESEL PARTICULATE FILTER (DPF)
(for 1.3 Multijet 75 HP versions)
The Diesel Particulate Filter is a mechanical filter, inte-
gral with the exhaust system, that physically traps partic-
ulates present in the exhaust gases of diesel engines.
The diesel particulate filter has been adopted to eliminate
almost all particulates in compliance with current/future
legal regulations.
During normal use of the vehicle, the engine control unit
records a set of data (e.g.: travel time, type of route, tem-
peratures, etc.) and it will then calculate how much par-
ticulates has been trapped by the filter.
Since this filter physically traps particulate, it should be re-
generated (cleaned) at regular intervals by burning carbon
particles.
The regeneration procedure is controlled automatically by
the engine management control unit according to the fil-
ter conditions and vehicle use conditions.
There may be a limited increase in the engine idle speed
during the regeneration, a limited increase in fumes and
high temperatures at the exhaust. These are not faults;
they do not impair vehicle performance or damage the
environment.

The following devices are used for reducing petrol fuel
engine emissions:
❒
three-way 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 en-
gine emissions:
❒
oxidising catalytic converter;
❒
exhaust gas recirculation system (E.G.R.);
❒
diesel particulate filter (DPF).
The catalytic converter develops high tem-
perature during operation. Do not park
the car on grass, dry leaves, pine needles or oth-
er flammable material: fire hazard.
