DIESEL PARTICULATE FILTER
(DPF)
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 car, the engine
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 car.
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 car performance and envi-
ronment.
If the dedicated message is displayed, re-
fer to section “Warning lights and mes-
sages”.
During normal service the
diesel particulate filter (DPF)
reaches high temperatures. Do not
therefore park the car over inflam-
mable materials (grass, dry leaves,
pine needles, etc.): fire hazard.
WARNING
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.
