PROTECTING THE ENVIRONMENT
The following devices are used for reducing diesel
fuel engine emissions:
❒ oxidising catalytic converter
❒ exhaust gas recirculation system (EGR)
❒ particulate filter (DPF).
WARNING
Under normal operating conditions, the
silencer becomes very hot.Therefore
do not park the car on flammable materials
(grass, dry leaves, pine needles, etc.): fire
hazard.
DIESEL PARTICULATE FILTER (DPF)
(for versions/markets, where provided)
The Diesel Particulate Filter is a mechanical filter,
integral with the exhaust system, that physically traps
particulates 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, temperatures, etc.) and it will then calculate
how much particulate 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 controlled automatically by the engine
management control unit according to the filter
conditions and vehicle use conditions. There may be
a limited increase in the engine 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.
