DIESEL PARTICULATE FILTER (DPF)
The Diesel Particulate Filter is a mechanical filter, inte-
gral to the exhaust system, that physically traps particu-
lates present in the exhaust gases of diesel engines.
It is needed to eliminate almost all particulates in compli-
ance with current/future legislation.
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-
ticulate has been trapped by the filter.
Since this filter physically traps particulate, it should be
regenerated (cleaned) at regular intervals by burning the
carbon particles.
The regeneration procedure is handled automatically by
the engine control unit according to the filter conditions
and vehicle use conditions.
During regeneration, the following may occur: a limited in-
crease in the engine speed, activation of the fan, a limited
increase in fumes and high temperatures at the exhaust.
These are not faults; they do not impair vehicle perfor-
mance or damage the environment.

ing lights and messages” section.
PROTECTING THE ENVIRONMENT
The following devices are used for reducing diesel fuel en-
gine emissions:
❒
oxidising catalytic converter;
❒

INDEX
The diesel particulate filter (DPF) reaches
high temperatures during operation. There-
fore do not therefore park the vehicle on inflam-
mable materials (grass, dry leaves, pine needles,
etc.): fire hazard.
WARNING
The catalytic converter also reaches high
temperatures during normal operation.
Do not park the on grass, dry leaves, pine needles
or other flammable material: fire hazard.
