Diesel Particulate Filter (DPF)

Diesel Particulate Filter breakdown | Doosanequipment EMEA

The DPF filter removes PM from the engine’s exhaust gas. It consists of a ceramic wall flow filtration system that separates PM from the exhaust.


DPF characteristics

  • Reduced NOx by engine design
  • Better fuel efficiency
  • Compact technology and easy to install
  • No need for additives


DPF Regeneration

To keep the DPF clean and working efficiently, the high temperature of the exhaust itself is used to burn accumulated PM off the DPF. This semi-automatic cleaning process is called "Regeneration".
