DIESEL PARTICULATE
FILTER (DPF) (for Multijet
versions 1.3 85 HP and 1.9 120
HP)
The Diesel Particulate Filter is a me-
chanical 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 par-
ticulates in compliance with current /
future law regulations.
During normal use of the vehicle, the
engine control unit records a set of da-
ta (e.g.: travel time, type of route, tem-
peratures, etc.) and it will then calcu-
late how much particulates has been
trapped by the filter.
Since this filter physically traps partic-
ulates, it shall be cleaned (reclaimed) at
regular intervals by burning carbon par-
ticles.
Reclaiming procedure is controlled
automatically by the engine control unit
according to the filter conditions and
the conditions of use of the vehicle.
During reclaiming the following phe-
nomena could take place: idling slight
increase, fan activation, slight smoke in-
crease, high exhaust temperatures.
These situations shall not be considered
as faults and they do not affect vehicle
performance and environment.
If the dedicated message is displayed,
refer to paragraph "Warning lights and
messages".
