Depending on your driving, active regeneration may happen as often as once a day. If you do a lot of stop and go, it can happen even more often. Frequency depends on duty cycle and how much soot collects – as often as once a day or every other day An active regeneration could take up to one-half hour or more. There is a DPF (Diesel Particulate Filter) in the exhaust. It's usually in the muffler. The role of the DPF is to filter the black soot out of the exhaust Soot is created by unburned fuel which occurs mostly at low engine loads.like idling. So if you do a lot of idling, like city driving, you are going to produce a lot of soot which is going DPF replacement cost. Parts: $2,000 – $4,000 ; Labor: $500 – $1,000; Total repair over $3,500 typically; Preventing DPF failure through proper regen attention saves thousands in repairs. Summing Up DPF Regen. While regeneration may sound complex, it‘s a key emissions process that occurs automatically under normal driving once you The duration of an active regeneration event generally ranges from 20 to 30 minutes on average, under normal operating conditions. In some cases, such as severe DPF soot plugging, a parked regeneration may be required, which can last up to several hours to slowly burn off the soot under more controlled conditions. Blue smoke does emit due to dpf regeneration. Blue smoke due to dpf regeneration means that oil is getting in the engine. This is usually caused if the piston rings are worn out. It may also occur if you have poured more than the required amount of engine oil. Black smoke: Black smoke might be emitted for dpf regeneration. Regeneration”, which happens whenever the vehicle is at operating temperature, but with no other special engine conditions. And “Active Regeneration” which occurs when the vehicle is at operating temperature, running at a predetermined RPM and within a certain time frame, normally upwards of 15min. 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 . The Regeneration may take up to 40 minutes, the engine speed automatically increases to about 1500 RPM. [Select] [01 - Engine] [Coding-II - 11] Start Regeneration by Entering 10016. [Do It!] [Meas.
