Tank
IMPORTANT:
Dirt/dust, oil, greases, detergents and any chemicals
and
natural products must be prevented from entering
the Adblue/DEF tank.
The system will be damaged if dust or dirt enters the
tank clogging the filters in the dosing system.
Keep the tank clean at all times.
The AdBlue
®
/DEF-solution is stored in a separate
tank.
Tanks are made of plastic and are available in different
shapes and sizes.
There is a fitting in the tank that comprises a heating
coil (1), a float (2) and a filter (3) on the suction line to
prevent any particles from circulating through the
system and causing disruptions.
The filter must be checked and cleaned as necessary.
There is a drain plug (4) on the bottom of the tank so
that the solution can be emptied when necessary, e.g.
for cleaning.
The tank is fitted with a breather to equalize pressure
changes.
Tank level
AdBlue
®
/DEF solution consumption varies during
operations. The level in the tank is shown on the gauge
as a percentage of the total tank volume.
When the level in the tank falls below the limit, the level
sensor in the tank transmits a signal that closes the
injection valve. A fault code is set in the engine control
unit, a warning lamp lights up and a fault message is
shown on the control panel. If AdBlue
®
/DEF solution is
not added, injection into the exhaust pipe will cease
and engine rpm and torque will be limited. When
AdBlue
®
/DEF is added the fault message is canceled
and the engine is once again able to deliver full power.
Refer to Fault handling, page 58 for further
information.
Should the AdBlue
®
/DEF tank become empty during
operations this will not lead to damage to the engine or
Example of the location of an AdBlue
®
/DEF tank.
