Additional Notes

  • The Caterpillar CB13 and CB15 vibratory compactors, both starting from 2017, share an identical AdBlue (DEF) tank capacity of 19 liters within their selective catalytic reduction (SCR) systems. SCR systems use DEF to convert nitrogen oxides into nitrogen and water vapor through a chemical reaction in the exhaust stream, and the tank size directly determines how frequently refilling is required relative to fuel consumption.
  • The 19-liter DEF capacity listed for both the CB13 and CB15 applies under normal use conditions, meaning the figure reflects standard operating demands rather than severe-duty cycles or other adjusted service states.
  • A 19-liter DEF reservoir is a moderately sized tank for this class of compaction equipment, indicating a balance between minimizing refill frequency during continuous paving or compaction operations and keeping the overall system weight manageable on a machine of this type.
