What is DPF Regeneration?

DPF stands for Diesel Particulate Filter. DPF regeneration, also called DPF regen for short, is the process of burning off accumulated soot from the DPF to prevent it from clogging and reducing the engine's performance. The soot within the DPF is converted to ash through the use of heat, chemical reactions, and/or electricity. Soot combustion temperatures typically range from 250˚C - 350˚C (with a chemical or fuel catalyst), and up to 550˚C (Without a catalyst).

A diesel particulate filter (DPF) is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Wall-flow diesel particulate filters usually remove 85% or more of the soot and under certain conditions can attain soot removal efficiencies of close to 100%.

This particulate filter shown is made of sintered metal and lasts considerably longer than current ceramic models, since its special structure offers a high storage capacity for oil and additive combustion residues. The filter is designed in such a way that the filtered particulates are very evenly deposited, allowing the condition of the filter to be identified more reliably and its regeneration controlled far better than with other solutions. This diesel particulate filter is designed to last as long as the vehicle itself.

Benefit example:

  • Proper maintenance of the aftertreatment system is necessary to ensure optimal engine performance.
  • Minimize harmful emissions.
  • Extend the engine’s lifespan.

Use Case:

  • Notice a reduction in the engine's performance.
  • Burning smell.
  • DPF needs to be cleaned.
  • An Innova 5610 can perform a DPF regeneration or DPF reset on diesel vehicles that are supported.
