DPF problems: How diesel particle filters actually regenerate | Auto Expert John Cadogan Share Watch on Too much misinformation is being served up about how DPFs work and how they regenerate. It’s time to sort that out, here and now
This is because the DPF commands fuel to perform regeneration. Eliminating the DPF thereby eliminates the need for regeneration, making a tank of fuel go further. When it comes to overhead costs, fuel is one of the most expensive for owner-operators and fleet managers, so even a marginal savings can be significant.Here, a manual regen is the way to go. An ASH LOADED DPF is when the filter has reached it's capacity to hold the residual ash left over from regeneration. Here again, removing the filter and blowing it out with shop air simply is not effective. DPF ash cleaning is a process that involves baking the substrate and pulsing it with air. When your truck is under Derated, you have to do the following step by FCAR truck scanner if there is not physical part failure: 1) Go Diesel Engine, select Cummins, it will show couple DPF/DEF/Aftertream related codes. This is Hardcodes, it wouldn't be able to remove by scanner. 2) Under Cummins main menui, selction Action Test to find Forced
3. Select Toolbox-Powertrain-Service Funtions-DPF manual regeneration also, keep drilling down to Diesel particulate regeneration system- DPF manual regeneration. 4. One or both of those will be changed to “Yes” 5. Go to the gauge display on the IC, and the regen % will be on the third page. The 4th will still be blank.
The tag on the frame shows Type M6060D right above ser number 50562. So I assumed Type and Model were the same but maybe not, then looking on the invoice from Jan 2018 it shows Model M6060HDC, I bought this thing used. The manual 3C631-9971-1 was for sale on ebay and I just missed out on it, and in the same ad they also have manual 3C631-9971-2 Burning off the soot is known as regeneration, and it happens in 2 ways. DPF passive regeneration. Passive regeneration was designed to actively burn off the soot during some instances of regular driving. When the exhaust temperature increases to a high enough level (around 500°C), the DPF can cleanly burn off the excess soot in its filter. I can also foresee a problem or you saturating the filter with carbon to a point at which if you shut your engine down while the DPF is still hot or in regen, you could have a runaway oxidation reaction in the filter which would damage the rest of the exhaust system at the very least since the heat can't be carried out the exhaust like it is DPF can accumulate and combust PM within the filter element to achieve greater than 85 percent reductions in PM emissions. The combustion of PM in a filter occurs during regeneration. During normal operation a DPF will cause fluctuations in exhaust backpressure as PM is accumulated. Consequently, a DPF is used in conjunctionDIY vs Professional DPF Regeneration. If you own a VW Golf and are experiencing issues with your Diesel Particulate Filter (DPF), there are two options to consider: DIY regeneration or professional regeneration. A DIY approach involves manually regenerating the filter by driving at high speeds for an extended period, usually on the highway.
I noticed that my DPF filter was reading 95%. Opened Forscan and it said that the the filter was only at 37% full. Tried to do a manual static regen but Forscan would not let me because the values were to low. Went to my Ford Diesel mechanic and he was able to force a regen with the Ford software. After about 30 minutes the task was completed.Particle filter: time since last regeneration 40855 s Particle filter: soot mass calculated 34.93 g Particle filter: soot mass measured 16.68 g 3rd reading take enroute, about 25mins into the trip, on the freeway at 110kms when a regen had just taken place. Laptop was hooked up all the way: Particle filter: time since last regeneration 60 s
The ECM uses the following criteria to perform a regeneration: Vehicle in Drive. BARO sensor 1 is more than 51 kPa (7.4 PSI) Engine speed between 500 and 4000 RPM. Exhaust Gas Temperature Sensor 1 between 100 and 725 C. Exhaust Gas Temperature Sensor 2 between 95 and 750 C.QkGg2.
