Tank volumes
The tank volumes specified in the table below are defined as follows:
• Total volume: The sum of fill volume, expansion volume and reserve volume.
• Expansion volume (A): The space required for the reductant to expand if it freez-
es. The reductant expands by 7% when freezing, and the freezing point is -11°C.
• Fill volume (B): Volume available for metering.
• Reserve volume (C): The volume required to prevent air from entering the sys-
tem, and to cool the reductant doser. The system automatically stops metering re-
ductant when the level has dropped to the reserve volume.
The reductant doser is cooled using the reductant. If the reductant doser is not cooled,
it breaks after a few minutes under normal exhaust gas temperature. Therefore, there
must always be at least a reserve volume in the tank.
