Operation
Diesel particulate filter
Diesel particulate filter
Under normal circumstances, automatic
regeneration of the diesel particulate fil-
ter is sufficient to avoid heavy soot load-
ing of the filter. However, if the bus is
predominantly driven short distances or
with the engine under low load, it might
not be possible for automatic regenera-
tion to finish successfully.
A yellow "particle filter" indicator lamp
in the instrument cluster will then warn
that the diesel particulate filter is nearing
a high load state and indicate that action
may need to be taken.
The on-board computer gives prompt
warnings of emission-relevant malfunc-
tions or user errors and displays their
respective priority by means of a grey,
yellow or red event window along with
the associated plain text message.
If these event windows and their instruc-
tions are disregarded, there is a risk of
engine power output being reduced and
a need to exchange the diesel particulate
filter prematurely.
Note:
As long as no flashing yellow or constant
red malfunction alert appears, it can also
be sufficient to alter the load profile (e.g.
take the bus for a drive on the motor-
way) in order to ensure that automatic
regeneration of the diesel particulate filter
finishes successfully.
Note:
In the event of a malfunction in the
BlueTec® exhaust gas aftertreatment
system, have the system checked
and repaired at a qualified specialist
workshop.
Danger.
Exhaust fumes are produced during the
manual regeneration process (parked re-
generation). If you were to inhale these
exhaust fumes, you could suffer harm-
ful effects such as poisoning. For this
reason, the bus should always be parked
outdoors. If, however, the bus is parked
in an enclosed room, adequate ventilation
must be ensured.
Danger.
Very hot exhaust fumes are expelled from
the exhaust tail pipe during the manual
regeneration process (parked regenera-
tion). Keep well clear of the exhaust tail
pipe. Otherwise, you could be burned by
the fumes. The use of an extraction sys-
tem should be avoided because this will
generally not have been designed to with-
stand the exhaust temperature levels that
arise.
