  • Use: Normal
  • Capacity 17,5 liter

Additional Notes

  • The Caterpillar AP-1000F with AC4 engine, introduced in 2015, carries an AdBlue (DEF) system capacity of 17.5 liters, which represents the total tank fill volume for the selective catalytic reduction (SCR) system. SCR systems use DEF to chemically reduce nitrogen oxide emissions in diesel exhaust, and the tank size directly determines how frequently refilling is required relative to fuel consumption cycles.
  • The 17.5-liter DEF capacity on the AP-1000F AC4 is specified under normal use conditions, meaning the interval and consumption assumptions tied to that volume apply to standard operating environments rather than severe-duty cycles.
  • The presence of an SCR system notation on the AP-1000F AC4 configuration indicates the DEF capacity figure is specific to emissions-controlled engine variants, distinguishing it from any non-SCR powertrain configurations where no DEF tank would be present.
