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 Once the filter collects enough particles, it goes through a process called “regeneration.” This is when the DPF heats up and burns off the trapped soot particles, turning them into harmless ash. Just like that, your diesel engine runs cleaner and more efficiently, all thanks to your trusty DPF. Symptoms of a Clogged or Malfunctioning DPF How the DPF Regeneration Process Works. The DPF is designed to capture soot particles over time. When the filter becomes too clogged, it needs to be "regenerated" in order for it to continue functioning properly and save your engine. Regeneration is a process where the pollutants are burned off in high-temperature exhaust gases. 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 With respect to diesel engine exhaust aftertreatment systems, one of the most important elements is the regeneration that takes place with the system. Regeneration is the process of removing soot and other pollutants from the diesel particulate filter, or DPF. The two main methods for regeneration are active and passive regeneration. It went to 127% before regen. The last regen started at 509 miles. The DPF Soot gauge before last regen was at 3.0 g/l and dropped to 1.53 g/l after regen. One other thing that concerns me is the DPF DP is 39 psi. MPG has increased some since using Motorcraft fuel additive. It seems to me that the filter doesn't get a thorough cleaning. 2. A dialogue box will display the coolant temperature. Wait until the temperature reaches the correct value. See test conditions. 3. Click on "OK" to start the regeneration. 4. A dialogue box will display the regeneration status. If the combustion must be cancelled, select "Cancel" and switch the ignition off once the engine speed has stabilized. When the engine goes into regen, drop a few gears to keep engine RPM up to near 2000 RPM or more. My truck normally tries to limit RPM to 1250. I don't know why the regen process does not automatically increase engine RPM. Eventually the DPF filter will become saturated with ash and need to be replaced or cleaned off-truck. The DPF is basically a good system, but you must operate your diesel at higher rpm than most normally do, this to encourage automatic regens as you work. Consistent short time use of a tractor, at low rpm can quickly fill the DPF with particulates. So the harder you work your tractor, the better your DPF gets cleaned.
