During the regeneration process, the PCM raises the temperature in the DPF to burn off the soot accumulated. Under normal operation, the engine does not produce enough heat to oxidize the soot inside the DPF. This process requires temperatures above 550 ºC (1,022 ºF). 16 regeneration minutes /3,600 = .00444 = 4/10s of 1% of engine time is consumed during parked regeneration. Fuel cost for sixteen minute parked regeneration @ 2,200 rpm ~~$1.00. Diesel Particulate Filter supersedes tractor muffler. At some point in time DPF needs to be replaced. It has never gone a complete regeneration; as I was pushing the button that stops generation not knowing what I was doing.I had it two years it has about 50 hours on it. I tend not to use it for long sections of time lately as I was digging post holes only a couple at a time lately; so my answer is most likely not as it was running maybe 20 2008 Ford F-350 Super Duty 123,000 mi, Visitor. DPF cleaning cycle is almost a daily issue, when in cleaning cycle I loose power and fuel gage drops fast. 2012 Ford F-350 Super Duty 100,000 mi, Visitor. Cleaning exhaust filter light comes on while on interstate doing 70. Truck slows down to 45. On an LML the active regen process initiates once 42 grams of soot have collected in the DPF or after 700 miles without active regen (whichever comes first). DPF temperatures during an active regen will quickly climb to 1000 deg F in order to quickly burn collected soot off and allow the DPF differential pressure to come back down. OTR Diagnostics allows you to read and reset fault codes, view live data, and run advanced diagnostic functions, including forced DPF regen with your mobile phone or tablet. The DPF system will typically give you some warning signs before going into a major derate or failure. One of the most common ones is to perform a parked regeneration. 9jwX. Score: 4.4/5 (30 votes) A Parked Regeneration will stop if the key is turned to the off position, the truck is put into gear or the parking brake is released. The regeneration will take approximately 20-40 min. The regeneration is complete when the engine returns to low idle and the DPF lamp remains off. I am a lady driving a Peugeot 3008 1.6 diesel EGC doing about 10,000 miles a year, mostly on short runs of between 10 and 15 miles with only an occasional longer one. I keep reading about the particulate filter and its adverse effects. Can you please explain what you consider a short journey and how long you must run the engine when stationary? In a recent reply you wrote "the DFP was This process of regeneration refers to the soot being burned away with a high temperature in the Diesel Particulate Filter (DPF). The regeneration takes place automatically while we steadily drive the car, preferably on a highway. Most engines of a new car will actively regenerate DPF if the car is speeding above 40mph for at least 10-15 minutes. During the regeneration process, the PCM raises the temperature in the DPF to burn off the soot accumulated. Under normal operation, the engine does not produce enough heat to oxidize the soot inside the DPF. This process requires temperatures above 550 ºC (1,022 ºF). So for the last 18 months or so, I've noted my coolant temperature has been below the 82°C-89°C called out as normal. Generally as I drove around it would run 78° to 80°C, and having noted the thread elsewhere about the risks of damage to the expensive DPF if the cold engine prevented a regen cycle, I've been watching it closely, and noting that regeneration cycles continued to happen No, petrol cars don’t have a DPF. But they do have an OPF (Otto Particulate Filter). This has been mandatory since 2018 and works to reduce harmful matter from the exhaust pipe. Newer cars have quieter OPFs than older models. How long does a DPF last? If maintained well and driven for longer journeys, a DPF should last up to 100,000 miles.
