How often does a diesel do a regen? Diesel engines emit a lot of soot (particulate matter), which can irritate the lungs and increase the risk of cardiovascular disease. Since 2009, modern diesel cars have been required to incorporate a Diesel Particulate Filter (DPF) in the exhaust system to prevent soot from entering the atmosphere. Driving normally and avoiding short trips facilitates regen to keep your DPF running cleanly. How Long Does Regen Take? Regen times depend on the soot level, vehicle condition, and type: Passive regen – Average of 5-10 minutes; Active regen – Typically 10-30 minutes ; Parked regen – Can take over an hour if DPF is overloaded “Doing a regen more often in an effort to avoid ‘cleaning’ of the DPF has more of an opportunity to cause DPF damage than not doing a regen,” he adds. “Doing back-to-back forced regens to get the DPF differential pressure to below its derate threshold risks creating too much exhaust back pressure on the DPF and can cause the DPF Cummins, even before DPFs, recommends to start driving "gently" as soon as oil pressure comes up (in summer this is less than a minute). Keep driving gently until the engine temp comes up, then drive normal. This also helps prevent cylinder wash down and extra cylinder wall wear. 08-26-2023, 08:06 AM. The 10-minute regen timer is just a notification that a parked regen needs to occur. A parked regen is going to go through a full cycle to ensure everything related to the engine and aftertreatment system is working properly. The aftertreatment covers the EGR, DPF, DEF, SCR systems. What is regeneration and how often does it occur? Regeneration is a process used to remove Carbon (C) build up from the DPF catalyst. This process occurs on a regular frequency that varies based on system and application. For example a 2007 system might have regenerated every 12-24 hrs whereas our 2017 systems might make it >100hrs before Cleaning vs. replacing DPFI realize the cost is significantly higher for replacing, but I am wondering what I should do based on my circumstances. I drive 100,000 miles a year (actually in 49 weeks). 99% is all 65-75 mph. Just turned over 212,000 and my drivetrain malfunction light came on. How often should DPF Regenerations take place? by Kevin Sanders | Extend Regen Cycles So what’s the answer? Your DPF regenerates because of excessive exhaust soot overwhelming the DPF. Exhaust soot is the product of incomplete combustion, the soot is actually partially burned fuel. v6qbQM2.
