When Active Regeneration, does not occur, Forced Regeneration may be needed to clear the DPF of soot. The Forced Regeneration procedure is in your ownerâs manual. Note: there are heat and burn hazards associated with regeneration. Always follow the specified safety precautions as per ownerâs manual.
Some manufacturers and engines require the soot level to be above a certain percentage for a stationary/forced regeneration to occur. This is usually more of a problem in earlier year model truck engines (mainly EPA2007 engines), but has been seen in later years as well.
The system will try to run a regeneration process for 15 minutes. If unsuccessful, the system will repeat this process for a further 15 minutes, if still unsuccessful, the DPF light on the driver display panel will then be lit. You can monitor the soot level in the DPF with Vag-Com, here's how.
The regeneration process âcleanlyâ burns off the particulates/soot with a DPF able to reduce particulate emissions by around 80% compared with your diesel-powered vehicle not having one.
to ash during filter regeneration. Regeneration occurs when the filter element reaches the temperature required for combustion of the PM. âPassiveâ regeneration occurs when the exhaust gas temperatures are high enough to initiate combustion of the accumulated PM in the DPF, without added fuel, heat or driver action. âActiveâ
What is regeneration? ⢠Regeneration is when heat causes soot (carbon) in the DPF to combine with oxygen and convert it into carbon dioxide. ⢠Passive regeneration occurs when the engineâs heat is high enough to oxidize the soot during normal operation. ⢠Active regeneration requires fuel to be injected into the exhaust system to

Passive Regeneration: Passive regeneration occurs naturally during normal driving conditions. When the exhaust temperature reaches a certain level , typically above 600 degrees Celsius , the soot particles trapped in the DPF are oxidized and converted into less harmful substances , such as carbon dioxide and water vapor .
When the soot accumulation reaches a level that is potentially damaging to the engine or the exhaust system, the solution involves a garage using a computer program to run a regeneration of the DPF manually. When a regeneration occurs, the soot is turned to gasses and ash of which some remains in the filter.
You get better combustion, faster more efficient burn and a dramatic reduction in soot. Less soot = Less need for DPF regeneration. Thatâs how DPF Remedy solves DPF problems starting with the first tank of treated fuel. Many of our clients have seen daily regens go to weekly or monthly regens.
May 27, 2022 by Tony Lohman. Mack regeneration problems often arise â and it can be a concern to operators when these happen. Generally, a DPF regen, otherwise known as regeneration, occurs during the burning of accumulated soot in the DPF to prevent risks of clogging. Your truck may either carry out active or passive DPF regens.
