This restriction, plus added EGR, plus post-injection events, make up the active regen. All or any can be applied at any particular time and they do make the engine feel a but "boggy", especially as the throttle takes a moment to motor open when you stab the go-pedal. Driving hard will heat the DPF sufficiently that passive regeneration will occur. inadequate filter regeneration will cause a DPF to require more frequent cleaning. Diagnostics should be performed to identify the cause for more frequent cleaning intervals. A backpressure monitoring system should always be used with a DPF and periodic inspection of the monitoring system should be performed to confirm proper operation. Not easy on Cornish roads! If the regenerations are working correctly you won't need the high revs and or distance. The autobox will be controlled by the ECU, just don't fight it and put it in a higher gear manually. I find it will want about 1,800rpm, during the first stages of a regeneration. Doesn't up change as normal, during a regen. Also, the PCM may not kick the false-positive code. These are the signs that tell you to Regen the DPF. Things To Consider Before Forcing Regen 6.7 Powerstroke. Before you opt for the process of regenerating your 6.7-power stroke, you have to do a static. That will give you instructions about the preparation needed to perform the regen prior. Diesel Particulate Filters (DPF) are an important component in your diesel engine that ensure your engine runs much cleaner than older engines. DPF are extremely effective at trapping even the finest soot particles that are produced as the engine burns diesel fuel. The result is less soot particles entering the atmosphere. – After about 10 miles my temp started rising and peeked at 93c, this is DPF doing its thing. – Rear view mirror = sooty clouds occupied by eggy smell later. – Exhaust tips sooty. I suspect the EGR thermostat was the initial culprit but once it throws the DPF warning fault codes keep the car stuck a loop. Passive regeneration occurs, to some extent, in all DPF systems. Perkins has engines are available that are passive only – so there’s no need for any active system. If you’re looking for a simple solution that is invisible to the operator, passive regeneration is a logical choice. There are no extra lights or controls to increase the 6.4 Regen Info. Diesel particulates in the exhaust are trapped by the DPF. Regeneration is the process by which exhaust temperatures are increased so the particulates are combusted. The frequency and length of regeneration will fluctuate as both are determined by the drive cycle. For most drive conditions, regeneration frequency will vary from lHs6VR.
