A passive regeneration occurs when the vehicle exhaust system has reached a particular temperature after a sustained period of driving at specific speeds. Generally, this occurs when driving on a motorway at speeds of around 50-70mph for more than 30 minutes. Manual Regeneration: Regeneration is initiated by the driver using a DPF switch fitted in the vehicle. In order for manual regeneration to occur, the driver must push the DPF switch when the vehicle is stationary with the engine running. Engine RPM will increase until the exhaust becomes hot enough to burn off the PM (soot) collected in the DPF. Passive regeneration occurs naturally under steady driving, when the engine achieves the required operating temperature. The DPF contains an oxidation catalyst that is coated with precious metals. Under normal highway driving, passive regeneration takes place as the catalyst in the DPF heats up enough to oxidize the soot and turn it into CO2. Regeneration is the term used to describe cleaning of the DPF. During this process the ‘wet and sooty’ particulate matter is subjected to further combustion inside the DPF itself. Surface temperatures inside the DPF can exceed 600 Degrees Celsius, at which point the soot turns into a hot white ash. Some of this ash is blown out of the It needs to do at least 15 motorway miles before it starts to regenerate and burn off all of those nasty particulates. Failure to do this could cause the filter becoming clogged up and failing, which will result in expensive bills for cleaning or replacing the DPF. One final consideration, it takes time for a DPF to block, sometimes years. Once blocked though, turbo failure can occur very quickly. If you don’t check for a DPF issue when installing a replacement turbo, there is a very high chance the replacement turbo will suffer the same failure, as it will be subject to the same operating environment as the previous unit. 2020 king ranch. F-2fiddy Tremor said: Question about DPF regeneration. I’ve had my 2020 F-250 with the 6.7L Powerstroke since mid August, currently sitting at around 900 miles. I had manual regen turned on by the dealership when I purchased it. The DPF shows 90% full and has shown that for a couple weeks. If a regeneration event is interrupted for any reason, it will continue, including the next key cycle, when the conditions are met for regeneration enablement. Normal regeneration is transparent to the customer. The self-cleaning occurs approximately once per tank of fuel. A scan tool is required for service regeneration.
