Your truck will regenerate (active) when the DPF soot level reaches 65%. This will likely occur every 100-300 miles. You will only see the notice on the EVIC if the soot level reaches 80-90% due to uncompleted regens. Active self-regeneration occurs when there is not sufficient heat in the exhaust to convert all the carbon being collected in
In either application, operators should be prepared for active regeneration. Automatic vs. Parked Active Regeneration. There are two types of active regeneration: automatic and parked. Automatic regeneration is required when the soot load percentage of the filter is at least 77%, and passive cleanings have not been successful.

Passive regeneration takes place during normal driving but, due to the high exhaust temperatures needed, usually only on long or high speed runs.
My daily round trip commute is 120 miles at 70 mph, these are good DPF regen conditions. Exhaust gas backpressure before DPF is always 6 - 20 mbar at any one time, and all investigating mechanics have been happy with this. One one occasion I had the DPF taken off and hydro-cleaned, and red stuff came out (probably oxidation from old cleaner
to ash during filter regeneration. Regeneration occurs when the filter element reaches the temperature required for combustion of the PM. āPassiveā 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. āActiveā
When an active regeneration has been interrupted (such as this morning) is it advisable to take the car for a long drive to start the regeneration (passive or active) and clear out the dpf? Suppose an active regeneration occurs and takes the soot loading to say 20% when interrupted.
A passive regeneration occurs when the vehicle exhaust system has reached a particular temperature after a sustained period of driving at specific speeds. Generally, this occurs when driving on a motorway at speeds of around 50-70mph for more than 30 minutes.
Mar 1, 2019. #3. The light only illuminates when there is an urgent need to allow the car to do a regeneration cycle. From the 500X Owner's Manual: "DPF CLEANING (particulate trap) in progress (diesel versions with DPF only) The symbol switches on constantly to indicate that the DPF system needs to eliminate the trapped pollutants (particulate
The regeneration of a diesel particulate filter can be analyzed as a continuous, equilibrium process, the mass balance of which is given by Equation (9) [404]. The first term in the equation, dM/dĻ, represents the accumulation of soot in the filter. The two remaining terms in Equation (9) describe the oxidation of soot and the deposition of
Because the DPF is under the car, not āclose coupledā in the exhaust manifold, the car needs to be driven quite a long way (50 miles) at 2000 ā 2500 rpm to get the DPF hot enough to promote a passive regeneration.
Services provided by experts with experience in Kenworth DPF regeneration and Kenworth T660 DPF filter. 30 Min DPF Clean have worked on Kenworth Cummins DPF regeneration & DPF filter Kenworth since the day they introduced DOC/DPF combos into new models. Therefore, we are very familiar with cleaning of Kenworth DPF filters.
The regeneration cycle normally takes 15 to 25 minutes. Itās the extreme heat required for the DPF regeneration that causes most of the other problems. To be more specific, itās the interruption of the DPF regeneration heat cycle thatās the root cause of most of the trouble. For years, Mercedes told everyone the DPF regeneration is automatic.
They occur about every 300 miles with my driving pattern which I believe is when the distance invoked regen occurs. 160-170 miles if doing regular journeys of 20+ minutes on motorways seems to frequent. How do you know they are happening at that frequency?
If a journey is too short, the regeneration canāt be completed so the warning light will continue to appear since the DPF is still partially blocked. If this is the case, driving for 10 ā 20 minutes at speeds greater than 40mph, you could complete a regeneration cycle and clear the warning light.

how often does dpf regeneration occur
