How a Diesel Particulate Filter (DPF) works

During your diesel engine’s combustion process, particulate matter (PM) forms. Our diesel particulate filter (DPF) solutions capture a high percentage of PM or soot. Adding a DPF not only reduces the amount of PM released into the atmosphere, it can also help lower your fuel consumption, improve performance and minimise operating costs.

Particulate matter (PM) formed during combustion is captured in the DPF during engine operation. The DPF is regenerated, eliminating PM or soot that has been trapped through oxidation reactions, either passively or actively. Perkins has wall flow and flow through options available.

What are the strengths of a DPF solution?

  • A DPF solution allows for lower fuel consumption and better transient response and performance
  • Operators will find they can minimise the total system operating cost compared to a no- DPF system
  • Wall-flow filters meet regulatory requirements of all regions that require DPF

Our DPF solution, for off-highway applications, is available on models in the 854 and 1200 Series.

Cleaning your particulate filter

Cleaning your particulate filter

Cleaning of the DPF, which removes soot and other build-up from your engine, should be carried out at specified intervals as part of your routine maintenance programme.
