DIESEL PARTICULATE FILTER (DPF)
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 particular filter has been adopted to
eliminate almost totally particulates in compliance with
current / future law regulations.
During normal use of the car, 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
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 automatically by
the engine control unit according to the filter
conditions and the conditions of use of the car.
During reclaiming the following phenomena 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
car performance and environment.
