regen

[DEickhoff]

I haven't gotten my truck yet as it is sitting in WA waiting to be shipped up to Alaska. After reading all of the posts on folks having issues with the regen/clogged DPF, etc and I beginning to get nervous about this truck as I live on a small island and the nearest dealer will be over 500 miles away (can not drive directly to dealer, must take a 12 hour ferry ride and then drive 500 miles).



So my question to the techies out there is how can I ensure the truck does this regen process? Driving the truck for 45 minutes at 70/75mph is not going to be possible. :{



Would sitting in a parking lot, selector in Neutral or Drive and idling the engine at 1200 or 1800 rpm for X amount of time be good enough to trigger a regen?



Most of my driving to and from work is 20 miles and has a stretch of maybe a mile in which I can get upto 65mph. The rest of my driving is going to be town stop and go. This may be an excuse to run out to the end of the roads but even there my max, sustainable speeds will be 45mph.

well bro, hoestly i would not get that truck and try to find one with a 5. 9l. they are out there and you will not be happy with the 6. 7 after many ferry rides and a trip. you will probably not be able to make that trip under your own power as that filter will clog and shut the truck down. i couldnt tell the difference in pulling and the 5. 9l gets a hell of alot better fuel mileage. also i have been in 20 bleow weather and my 04. 5 5. 9 started with noproblem and it did not have a block heater. couldn't tell what the 6. 7l will do in cold weather

You may end up being the first to try a "particulate filter test pipe".

Hi Dawna, I am about to pick up my truck this week and share your concerns.

For a bit of encouragement about some "starting/running" issues, see this thread (post #8):

https://www.turbodieselregister.com...sions-2007-5/184769-finally-have-problem.html



The reported time/speed requirements for regen completion are another thing, of course. If D/C doesn't get a grip on this in a hurry, I predict their sales will go in the tank. As-stated, they are ridiculous in any normal operation (i. e. , anything other than extended highway running).



The very idea that a $50,000 truck may decide not-to-run because of incompleted regen, when we are truck-camper loaded at a remote fish camp on the western side of Vancouver Island, B. C. (or worse yet, on the boat-launching ramp, with others waiting), is absurd.



Does D/C assume the only use of these things will be continuous long-haul towing? Wonder what the liability aspects of this situation are, when people are inconvenienced or harmed(medical emergencies?) when reasonable-to-expect performance is not forthcoming?



I dislike the litigious society we live in,... but the words "class-action" come to mind.



How much field-testing of these rigs was done, anyway?



Maybe those Germans who bailed-out were smarter than we knew!



Gonna talk with my salespeople (Macomber/Ullrich - Dishman Dodge) Monday,... presumably they know there is a sales disaster in the wings, and are hot to get info on this issue.



Let's see,... possible loss of deposit vs. possible loss of entire value of unsellable, unuseable truck. Hmmm. Where's a rocket scientist when you need one?



I suggest getting on the phone to your dealer, steer him to these threads, and make known how shaky the deal is because of these reports.



Somebody needs their feet held to the fire on this thing.

I too would suggest bailing out on the 6. 7L. There are still 5. 9 trucks out there and from what I read it isn't worth the gamble.



The notion that sales will tank if they don't immediately address this doesn't sound right to me. Ford sold the 6. 0 diesel to hundreds of thousands of dupes who didn't do their homework. They did it for 4 years, flat amazes me that people spent big money on such a well known POS. I suspect Dodge will survive this too. For the sake of all out there though, sooner would be better than later.

 

[Tinman]

Are LMM and 6. 4 having the same problems? If so, this problem isn't so much a D/C or Cummins issue as it is a fact the the technology just isn't ready to meet the EPA's standards. I was under the impression that the new Cummins emission systems had been in use for many year with good results in Europe. What you guys are saying isn't good at all. Boy am I glad I jumped on an '06 will I could.

Concerns about DPF clogging

I have an email into Adam (Dishman) stating my concerns about all of this. I hope he will have some news/information for me that I can pass onto all of you here. I irks me that they (Dodge/Cummins) did not do any realistic driving testing prior to releasing these trucks for production. Not everyone drives or can drive these trucks as hard as they need to to clear the DPF. Perhaps there will be more information/solutions/third party solutions out prior to me picking up my truck around the first of July.

sure glad I have a 2nd. gen. even with all the lift pump ,vp44 and 53 blocks . my truck has 450,000kms and has never had a start ,driveability problem. still has the 53 block and original vp-44. would never trade this truck for any of the newer ones. they are just getting too complicated.

Pray that all you dont have all the problems with the 6. 7 like ford had with the 6. 0

As a whole, the third gen trucks have been more reliable than the second gens. That coupled with more power, better features, and vastly improved handling and braking make them tough to beat. I am on my sixth one, all have been great. This 6. 7 fiasco was brought on my the EPA. Other than the complex emissions junk, the trucks are still very simple and reliable.

I think it is the fuel people are using and not the truck

 

[bhendershott]

I have had my 6. 7 one week & with 400 miles on it the catalyst was 100% plugged. Drove it 150 miles & still no regen. Anyone else having this problem. Other than that eveything is great

Yes, several are and you can find it here https://www.turbodieselregister.com/forums/6-7l-engine-transmissions-2007-5/184304-am-i-only-one-having-problems-new-motor.html

Random question... . do the people that are experiencing clogged DPFs use cruise control alot?

The reason I ask is if regen only happens when the throttle is pressed, during cruise control the accel pedal is not pressed and if Dodge goofed regen may not be engauged.

Well taken, that is an interesting point. Does anyone have any documented info that might substantiate or disprove this theory?

 

[Jeepstang]

I will have the documentation this week and post once I read it. my friend took classes on this he is going to be bringing me the books. he said if a regen is stopped it will restart again when you start driving it again he also said it can do a regen at idle and the DPF is rated for 100,000 miles. If you run low sulfer not ultra low sulfer they will clog of quickly.

 

[mhlbr]

can someone explain to me what exactly "regen" is in these 6. 7's? I just bought a new one and pick it up in a month

 

[DEickhoff]

JJurgrau--that is awesome news to hear that the regen can take place at idle and that this might be a fuel issue. Anything you can post that would explain this or give us more information would be great. The lack of information is what is hurting right now and no one seems to know where to turn to get it.

My understanding is that the only fuel on the market today is ULSD. They started phasing it in at least 9 months ago and I doubt that other than off-highway fuel, you couldn't buy the wrong fuel if you wanted too.

 

[JSmole]

Check out the link here from Cummins. Is a document on and about the DPF and regeneration cycle. Some good information.

As for the fuel if it is not green is not ULSD, there is LSD still out there, some plants are still producing it. Here is Cal. there is only USLD as of Jan. 1, not sure how many others have made the switch. Check that color before you filler-up!

I have been hearing to as well, don't be gentle on these motors, run them the way they were made, Strong.
