DIESEL PARTICULATE FILTER
(DPF)
(for versions/markets, where provided)
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 engine.
The diesel particulate filter has been
adopted to eliminate almost totally par-
ticulates in compliance with current / fu-
ture law regulations.
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 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 vehicle.
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 vehicle performance and en-
vironment.
During normal service the
diesel particulate filter (DPF)
reaches high temperatures. Do not
therefore park the vehicle over in-
flammable materials (grass, dry leaves,
pine needles, etc.): fire hazard.
WARNING
During normal service the
catalyst reaches high tem-
peratures. Do not therefore park the
vehicle over inflammable materials
(grass, dry leaves, pine needles, etc.):
fire hazard.
WARNING
PROTECTING
THE ENVIRONMENT
The devices for curtailing diesel engine
emissions are:
❒oxidising catalytic converter;
❒ exhaust gas recirculation system
(E.G.R.);
❒diesel particulate filter (DPF) (for ver-
sions/markets, where provided).
Diesel re-ignition pump
In case of the lack of fuel, it is necessary
to re-start the circuit:
❒ fill the fuel tank with at least 5 litres of
diesel;
❒ activate the manual re-operation pump,
situated under the engine casing under
the protection, until the fuel appears in
the transparent tube;
❒ activate the starting engine, until the en-
gine starts.
