Diesel Particulate Filters (DPF) - Dynamic description manual
regeneration of the diesel particulate filter (DPF)
A diesel particulate filter (DPF) is a device designed to remove polluting diesel engine particulate from exhaust gas;
when clogged, it needs to be regenerated.
The diesel particulate filter can be regenerated automatically or by forcing.
The regeneration process is signaled to the operator on the central monitor of the dashboard and with an acoustic
signal. The indication is necessary for the purposes of safety to warn the operator about the high exhaust temperature
reached during the process.
The automatic regeneration shall not affect engine performance. During the procedure, the operator can continue
working normally.
Under certain operating conditions automatic regeneration might not be completed (engine continuously stopping and
starting, lengthy periods at idle speed) and it must then be repeated.
The start of automatic regeneration, if set, is highlighted with the following warning light blinking on the
dashboard and the same symbol appears every 5 minutes on the central monitor with the word “ON”
combined with a single beep. On concluding the operation the symbol appears with the word “OFF” .
When the level of soot exceeds a certain level, the electronic control unit asks you to proceed with manual filter
regeneration.
NOTICE: If the filter is not regenerated when required, whether manually or by forcing, the functionality of the filter is
impaired. Continuing to ignore this request, besides greatly reducing engine horsepower, damages the filter to such
an extent that it is necessary for the dealer to replace the filter with a new one.
When the following warnings appear on the dashboard it is necessary to proceed as follows:
DPF to be regenerated
Start of automatic regeneration or, with the control, start
of forced regeneration
