Active --If the duty cycle does not produce high enough exhaust temperatures, the DPF becomes loaded with soot, which is indicated by its pressure sensors. Active regeneration is then required. During active regeneration, raw fuel is injected into the diesel oxidation catalyst (DOC) to achieve appropriate regeneration temperatures in the DPF.
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.

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).

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. To do so, start driving off and maintain a sustained speed of 80 to 100 KM per hour for 30 to 45 minutes to perform the regeneration. The DPF light turns off once you finish with the regeneration . In some cars, you can manually start the regeneration while driving or in a stationary/parked position. Drivers can just engage the parking brake or
