6.4L Power Stroke Engine and DrivetrainDiscussion of the 6.4L Power Stroke diesel engine and drivetrain in the 2008-Up Super Duty trucks. No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 6.4L Power Stroke engine.
Correct, I was an electronic technician, now in mgmt. Engineers always provide a challenge to us common-sense thinkers. I guess that keeps us on our toes and we keep them in check by presenting simple solutions in contrast to their complicated ones.
Unfortunately, this was questioned of ford in the beginning. Why not tell the owner at what stage the dpf is at and allow the owner to initiate the cycle. Like it is done in heavy trucks. It is supposed to have pressure sensors. If the owner does not initiate the regen cycle often enough then it could be automatic. They said they want it to be automatic and transparent i.e. the owner won't know it is happening, hence why they have shortened and in some cases removed the indication on the display. I was hoping at one point that an aftermarket tuning company would have done this but none has as of yet.

Seems surprising that no aftermarket tuner has included this type of feature. Would certainly sell me on it. Perhaps *everyone* is terrified of getting anywhere even close to the EPA regs.
Of course, we could rehash the old question of why Ford didn't simply plumb a dedicated injector right into (or just before) that damned old DPF.
Sorry, DPF/regen topics just make me crazy! I *love* my truck and I *HATE* that #$*& DPF.

I really don't find it a hassle based upon my use. My last regen was at about 350 miles and the previous two were 242 and 260 ish respectively as I was towing for those.
Running the banks seems to help. They really should have made a user interface to manually regen if desired.

Just remember that Ford didn't do it because they wanted to, they did it because they were forced to. This is all the Government's fault. They forced the car companies to put this stupid crap on our trucks, then force the oil companies to make a different type of fuel that has less energy, less yeild and a higher cost...just so our exhaust tips are clean.
It's pretty irritating.

... when was EPA standards call for A DPF AND What is the 2006 standards?
The EPA never required a DPF or any other specific hardware. The EPA only specifies tailpipe emission limits, in this case 0.02 grams of particulate matter per mile. Ford chose to use a DPF to meet the EPA standard. Emission Standards: USA: Cars and Light-Duty Trucks?Tier 2

It would increase the production cost and reduce the profit margin.

I *do* understand why Ford had to do it, I just don't understand the Mickey Mouse way they implemented it. IMO, very poor cost/benefit design decisions pushing everything out onto the owner/operator. Too many accountants spoil the soup.
Thanks. Wish you all weren't at the other corner of the US from ID.

Exactly my point.
The Government says it must be so..
Jump? Sure, how hey would you like us to jump?

Ok it gone.. On the highway 23 mpg (at 70 mph) to 26 mpg(65 mph) a 2 hour trip and in the city 22 mpg so far.
with exhaust filter and cat 13mpg highway only if I go under 65 mph and city 11 mpg if it not cleaning 6 in cleaning. And if it stuck in cleaning mode when your going to Florida at a fuel cost of $1000 one way and 5 dealer later.
So if I use less fuel does that means cleaner air over years or sooner.

Congrats! Please let us know your hand-calc MPG before/after, when you have the time and/or more fill-ups.
Thanks,

Sorry, it's not that simple.
Burning less fuel results in less carbon dioxide being emitted, but CO2 is the only tailpipe emission for which that's true.
There's no direct correlation between fuel economy and carbon monoxide, unburned hydrocarbons, particulate matter, nitrous oxides or formaldehyde tailpipe emissions.

I have found that simply putting the truck in park does not apparently end the regen cycle. I have watched the DPF temps continue to climb for quite some time during "driveway idle". I have also observed some very goofy cycles while on the road.
Yup, I've seen the same. As long as the DPF is hot enough (>800F), soot will continue to burn as long as there is oxygen in the exhaust. So might as well take advantage of it until it stops producing heat. I've been watching the EGR Valve desired opening. It cycles wide open right after regen completes and appears to kill any remaining burn.

Wow, how do you monitor that value? If SGII, which XGAUGE settings please?
That is a very interesting observation and would explain why the DPF temp drops so dramatically on completion when driving, unlike after a interrupted regen. My favorite Ford tech did tell me that the EGR is an important part of the regen cycle but didn't mention that. Very interesting .......
Thanks,
