DIESEL PARTICULATE FILTER (DPF)

(MultiJet versions with DPF only)

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.
