DPF Regen Frequency?

[F-2fiddy Tremor]

Question about DPF regeneration.

I’ve had my 2020 F-250 with the 6.7L Powerstroke since mid August, currently sitting at around 900 miles. I had manual regen turned on by the dealership when I purchased it. The DPF shows 90% full and has shown that for a couple weeks. It hasn’t automatically regened to my knowledge as the DPF % would’ve decreased.

For those with the 6.7 how often (mileage interval) do you experience a regen?

For those with manual regen turned on at what percent does it prompt you for a manual regen?

This is my first diesel truck and I just want to be sure it’s emissions friendly equipment is operating correctly, or possibly I’ve read too much into emission equipment failure and I’m making myself nervous. Any information would be greatly appreciated.

Thanks to all in advance!

I would like to know what everyone else is experiencing too, since this is also my first diesel truck.

For me, I catch mine doing regen cycles every 450-500 miles or so. It's not obvious to the driver, but it is obvious when your tank range starts plummeting along with your average MPG. One just occurred to me today and ended a bit before I got to the gas station. While driving with the windows down and at the pumps, I noticed a bit of a hot, burning fuel oil smell. It's kinda like burning engine oil but different enough to know it's not engine oil. Unless told otherwise, I'm going to assume that's from the DPF regen.

Just wondering why you have it set to manual regen? I have a 7.3 tremor, but work with diesel equipment and set them in auto for the regen, and let the system clean as it needs.

so mine is regen every 2 tanks of fuel so about 1200 to 1400 miles .... but with it being colder it has gone to 1000 to 1200 miles and regen lasts 20 to 35 mins

Are you doing primarily short trips?

Are you doing primarily short trips?

For a while, yes, obscenely short trips. Now the trips are no longer short. Yesterday's regen was unexpected, since it was exactly 500 miles after the last one which started and completed on the highway. There were no short trips in between. FYI, the truck only has 2000 miles on it. Each regen seems to last only 15 minutes.

Do short trips contribute to added soot in the DPF? Or does the ECU behave differently if short trips occur?

My understanding is that short trips are bad for Diesel engines with DPF. I understand that on long trips, the engine heats up enough to burn off particulates without a regen. Perhaps someone can correct me if I am wrong

Last time I was at service they told me usually every 200 miles region kicks in and the vehicle has to be above 30 mph but it’s a computer so it could say F it and just start

 

[TxTremor]

In general the when a diesel is working it will burn cleaner and more efficiently with the emission systems. On short trips that make it hard to get up to temp the soot can build up quicker requiring more frequent regens. At work my equipment that works hard has been pretty good so far, however the few that don’t seem to have more emissions issues, it has helped to bump up the rpms to help build heat on said equipment.
I leave everything in auto mode so that it is not dependent on an operator to perform the regen. My rule is leave it in auto and if it starts a regen it gets to finish, no shutdown until done. Usually last 20-30 mins. If it were just myself running equipment I could understand using manual mode too.

So in theory, if you only use the truck on highway cruising (75mph), it should never have to regen?

mine regen at dealer when test driving with 20 miles. didnt notice anything on dash just smelled it like my tractor does. smelled it again around 400 miles but the dash didnt display any info that it was doing it.

Just got my OBDLink MX+
It paired with my iPhone flawlessly.
I will hopefully be the master of my regens!

Interested to see what you miles between re-gens are. I'm guessing (by lack of boost & poor mileage) when mine regens. I am guessing about every 400-500 miles.

How about a picture of this installed in the OBD port, any risk of hitting your knees on it (every time you get in/out)?

 

[Loshad]

It only projects from the port by a bit over an inch.
Your knees are safe!

That guy who religiously logged his regens averaged 470 miles
per regen IIRC.

My 'normalized trigger for regen' shows 50% which is interesting as I'm at 430 miles. It also shows 215 between regens so does that mean I had one I wasn't aware of? ?
My engine had only 8 miles on it but a lot of idling when I picked it up so a regen at only 215 miles is possible.

I notice my mileage fall off about once every tank and that was the same on my 17' as well. So in my past truck 470 miles sounds about right. I'm at about 1700 miles now and have noticed the mpg drop 3 times so far.

I still don't know why they don't (with out forscan or having the dealer add OCR) allow you to see DPF percent in the dash cluster, not like its important or anything...

Ford decided to adopt Pentagon protocols - it's on a need to know basis, and the less you know the better it is for them.
I wonder if my old Navy clearance is good at Ford?

 

[MX619]

Old post, but I'm guessing mine is regen(ing) more often since I make more short drives.

The filter indeed clogs more if the engine is not getting hot regularly.

 

[JTredway]

There's a YouTube video from Ford that explained basically regens are every

• Roughly every 500 mi
• As heavily soot loaded by demand (guys towing wildly heavy generating soot loads)
• Passively (meaning not full but basically conditions are met to perform a Regen, I've experienced this just traveling long distances cruising hwy even with a 30% DPF load)

Obviously, certain conditions need to be met as well for these to be performed, EOT, ECT, etc
