Cleaning DPF

[mikes08powerstroke]

Is it harmful to my truck (2008 F350 6.4 Powerstroke) to stop driving and turn off the engine during the "Cleaning Exhaust Filter" cycle??

[Concussiveforce]

I think it can be if you do it for to long. Would probably plug up. I usually took mine for a good highway drive to clean it out if I was doing a lot of short city trips.

What you should do is put the vehicle in Park, then let it cool down for 5 minutes or so. When you put the vehicle in park it turns the Regen function off. By letting the vehicle run for several minutes longer your giving the engine enough time to burn off the excess fuel injected on the exhaust stroke. If you just turn the vehicle off, the extra fuel can sit inside the cylinders and when the rings cool off, wash the cylinder walls and drain to the oil pan. This will remove the necessary lube on those cylinders as well as dilute the oil.

Anytime I approach my destination and regen has just started or is still running by the time I arrive, I perform the above.

Smotrs, Thats strange I cant get mine to return to idle unless I put my foot on the brake, park dosnt seem to stop my regen, the egts keep high and it stays reved up. Sorry I cant help with the op's question.

That doesn't sound right. What was the last flash your truck received?

DPF DELETE... dammmn tree huggers are flucking the diesel word with emissions control crap.

I have a few buddies with 6.4's, and they make it a point not to shut the truck off during Re-Gen. I am unsure of how long the re-gen lasts, but I would figure Ford would incorporate something into starting the next re-gen sooner if the truck gets shut off during re-gen.

Pintey30 - unfortunately I disagree with your statement...I believe that its partly the irrational side of the 'diesel community' that brought the emissions gear on. I am not saying it is bad to roll coal, I enjoy it sometimes, when the time is right. However there are too many drivers with chips (Ford, Dodge, and Chevy all the same) that just roll smoke Everywhere...not caring. I understand that smoke is a byproduct of dumping fuel to create power, but there are too many trucks with not enough power that just dump fuel.

OP Sorry for the rant...but it is partly 'our' fault...

I agreee with Phil, if so many were not burning coal the DPF might not be, but you never know, I cant under stand how burning twice the fuel with a DPF can be better then with out and half the fuel?

If my truck is in regen and I shut it down, the regen will start again almost immediately when I start it back up.

[smotrs]

Same here Ryan. Personally, I feel it's more wasted feel to drive around aimlessly which uses more fuel then letting it idle in your parking spot.
