Diesel Particulate Filter.
Basically the new emissions crap on all diesel trucks built after 2007

 

ok, thanks for giving this newb the heads up on this diesel thing!

 

On Fords it will be the 2008 and newer models.

Other manufacturers are handling it differantly, for the most part, diesel engines built after January 1 2007 have to meet the 07 standards which means DPF equipped.

 

I just got my 08 about 3 weeks ago and have about 650 or so miles on it. I have talked with the head mechanic at the dealership and he wants me to ride over to get it reflashed in regards to the regen cycle. I just happen to be over there talking with him and we both noticed the idle on the truck increased and the exhaust was crazy hot. Meaning that even standing 3' away it would scald you. No joke. He said the reflash was to ensure the regen cycle only happened while driving. If you happened to be parked next to a car, fence, or anything with the slightest combustability, it would ignite for sure. I would sure be concerned riding in tall grass.
Did I mention that I freekin love this truck??

 

So how is it going since the reflash? has it limited the regens to only while driving? The other way sounds dangerous and is an obvious safety issue.

 

Thanks fellers

 

Regen while towing.


Sorry if this is old news. When towing a trailer etc. and regen commences you would normally lose some power. Ford mechanic who just took some training on this said to just STAND on the pedal and it would cease the regen until you did not need the extra power. I guess pulling a heavy trailer up a steep incline would be a good cause to go out of regen.

 

If your pulling a load up a grade, the engine should be producing enough heat of its own to allow passive regeneration. I don't know if the Ford system takes any passive regeneration into account. It should if it doesn't.

 

I think the Ford system works on active and passive regen.

 

I know that it does, but does the ECU reduce the soot level trigger accordingly during passive regen? In our system, we use a calculation to adjust soot level triggers based on many criteria for passive regeneration. This prevents unneccessary active regens that would waste fuel.
