If passive regeneration does occur then there should be no need for an active regeneration cylce to occur when towing a load (a travel trailer 7500 lbs) a highway speeds. When travelling unloaded it is fairly easy to determine when a regen cyle is occuring by watching the overhead MPG closely. Regular maintenance is crucial to ensure efficient regeneration in a Kubota tractor. Here are some recommended practices: 1. Keep the diesel particulate filter (DPF) clean and free from clogging. The DPF is a crucial component of the tractor’s emissions control system, and regular cleaning ensures optimal performance. You get better combustion, faster more efficient burn and a dramatic reduction in soot. Less soot = Less need for DPF regeneration. That’s 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. 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. 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 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. VCneFx. 1. Use compressed air to blow out any trapped particulates. You can do this by disconnecting the hose that goes from the exhaust pipe to the DPF filter. Then, use a compressor with an air nozzle to blow into the exhaust pipe. Doing this will clear out any particles that are stuck in the filter. When Active Regeneration, does not occur, Forced Regeneration may be needed to clear the DPF of soot. The Forced Regeneration procedure is in your owner’s manual. Note: there are heat and burn hazards associated with regeneration. Always follow the specified safety precautions as per owner’s manual. Active particulate filter regeneration. Because drivers often do not drive on motorways or high-speed roads, manufacturers came up with the idea of active regeneration. The active regeneration of the particulate filter occurs when the soot level in the DPF is around 40-45 % of its capacity. Diagnosis: plastic tee failed; DP sensor is reading exhaust pressure between DPF an d SCR on the low side and atmos pressure on the high side. To use a BMW diagnostics term, the negative DP value seems plausible. Oh well, on the positive side, regens now appear to be working again. 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 New DPF Regeneration Parameters on the 2017. I found these today in the new release of Forescan that was released this past week: I am monitoring it now on my truck. There are also 5 new PIDS that track the distance between the last 5 active regenerations. I do not known if I already have a DPF or sensor problem as the first 1800 miles or so I
