Yet Another Regen Qustion

I apologize if this has already been addresed in previous posts but I fell the need to ask. It involves not completing regen cycles, more often than not it goes into regen process at the most inconvenient time, shot drives pulling into work or the driveway, etc... Just wondering is this causing any immediate or long term harm to the emissions system or the motor. Appreciate any response, Thanks

The truck will continue to attempt a regen until execution is complete. If you shut down the truck prior to completion, it will simply restart the next time the truck is driven and reaches operating temperature. I don't believe stopping the truck prior to regen completion will cause damage (at least I hope not because I have done it). I refuse to drive around for 15-20 minutes just to let the stupid regen complete. I just try to plan a longer drive following an interrupted regen.

From what I have seen so far you will be fine stopping the regen, so long as you don't do it everytime and you do let it finish the cycle withing a few tries. If you never let it finish it will clog and start to cut power until you let it finish. If you still don't let it finish it will cause the truck to shutdown to prevent damage. That will cause a dealer trip, but you will be fine cutting it off every now and then.

The other concern is going to be fuel in the oil. With constant low speed regens you are dumping fuel into the motor on the exhaust stroke to be burnt downstream in the DPF.

However with the lower speeds you may actually be washing your cylinders more than pushing that fuel downstream.

So while we all shut it down without completing it sometimes, it is a good idea to get it completed and get out of that cycle.

Mine seems to start at the most inconvenient time as well. I have shut down several times in the middle, or begining of regen, and the only thing it does is smoke alot I guess because of the soot build up. Once it finishes it runs just fine.

Appreciate all the response, I figured as much but with the confirmation I rest a bit easier. What I can't understand is why Ford did not incorporate a means by which the driver can control the regen cycle by using something like an inhibitor switch. I know that option exists, I was responsible for building a new piece of fire apparatus with a Detriot 60 series power plant, they have incorporated such a thing so the operator can have complete control. Maybe ford engineers should take note of such an option.

Again thanks for the responses.

I spoke with Ford myself, corporate new ideas and with Chris Brewer, Chief Engineer for the 2011.

They took it under advisement.

In other words...we see the results.
