New Snoking Laramie

As I noted the Banks EB on the 2001.5 seems like it had more hold back. If RAM detuned the EB so as not to knock horses and cows over, .....

4:10's must hold back better as Ron is 5T heavier than us. Snoking

I have seen several long-time Ram/ Cummins owners speak of Banks EB & Pac Brake. My question is were those ever offered as factory options? Or standard equipment? A friend of mine who ran a 97 Second gen Cummins was surprised to hear that all 4th gens come standard with an EB.
Although sometimes the emissions on the ram seem to be a liability because it can have problems, we have benefitted from the addition of the EB.

My take is the only reason the EB is standard is so it can engage in active DPF regens.

Another question i have is, "Does the Cummins 5.0 on the Nissan Titan do active regens? It doesn't have an EB to apply a load during active regen. Or will those Cummins engines have serious DPF probs?

I have seen several long time Ram/Cummins owners speak of Banks EB & PacBrake on these forums.

I might be deviating slightly from the discussion, but wondered if these were ever offered as standard or factory options? A buddy of mine who ran a 97 second gen 500,000 miles was surprised to hear that the 4th gens come standard with an EB. Even though the emmissions system on the 4th gen seems to be a liability with so many things that COULD go wrong, we actually benefit from a factory standard EB that (to my knowledge) wasn't standard on previous hens.

The ONLY reason that the EB is standard is because it is there to provided a load to the engine during active regens.

Another question that gets even further off topic (and I hope Snoking doesn't get angry that I am hijacking his thread),
Is ....... "How the heck does that Nissan Titan Cummins 5.0 do active regens without an EB? I suspect the TItan Cummins will have serious DPF problems????

My EB will keep me within 1 mile of whatever speed I pulled my foot off the pedal. Doesn't matter if cruise control is engaged. If I'm on a downhill that is just enough for me to pick up speed I can pull my foot off at 43 mph, EB will engage when I get to about 44, slow me to about 43 then disengage. It works like a charm. Don't know why SNOKING would have that 5 mph gap. I've got 373s so I'm closer to his but my Auto EB is a lot tighter on speed control. I'm in the Smokies this week so I'm getting to use that part of its function more than at home on the coast.

My DW aka SWMbO and I went to Reno NV. When we left San Diego we had 223.4 miles on the new truck. I set the cruise control at 62mph. We averaged about 18.6 miles to the gal. (that is what I get with my trusty Texas Instrument TI-30Xa calculator) I think the computer in the truck says about 17 mpg. I don't really care that much I do know for sure it runs circles around my Old Blue Oval truck. We went to Reno and returned on 3 tanks of diesel. My old Ford we needed to fill up in Victorville, Ca. again in Bishop and then again in Gardnerville NV. Then we always fueled up in Reno, NV before starting out to come home. I left San Diego with a full tank , the toped it off in Bishop,CA. Then when we got to Reno, before we came home I filled up in Reno. Then when we got to Pearsonville,CA just outside of Ridgecrest CA. I toped the tank off.
Not only did the truck ride like we were driving on glass but it was like the truck wanted to run away and keep going.
Pulling Conway Summit it was like the truck wanted to run away. No hesitation what so ever. Even when my Ford was brand new it would loose speed pilling Conway Summit.

I set the EB on auto as we were coming back down Conway Summit, had the cruise control set at 62mph, the EB sure did its job, I only used the brakes one time coming down that 6% grade.
One day last week I set the EB on full almost stopped the truck without using the brakes. I do know for sure that the purchase of my 2016 2500 Ram Laramie was or I should say is Money Well Spent. I got my monies worth. I have a friend that has a 2nd Generation Ram 3/4 ton. 2001. she pulls a 4 horse trailer w/living quarters The only problem that she has had with the truck is the fuel pump went south on her. I am not sure how many miles she has on it, but its over 150k They replaced it with an after market fuel pump they mounted in in the frame rail.

I hate AUTO too. Every time I accidentally hit the EB twice, I want to plunge my hunting knife into the dash to gouge the AUTO out of my dash. That's why I have a manual G56 transmission.

It's easy! Full exhaust brake is whenever the accelerator is not used, the full exhaust brake will continue until the pedal is pressed again.The auto exhaust brake will hold speed to a predetermined MPh. It will NOT CONTINUE to brake .it will brake if your going down a steep grade and if you want to stay at 50,the brake will go on and off to Maintain that speed. The full EB will continue to brake and not turn off and on.so full will stop the truck and auto keeps the speed.on grades.as far as your g56 holding back a large load going down a long steep grade,you can forget that. That trailer will push you to red line every time you try to downshift. My nv5600 required an eb...

It's really simple, you pick the gear you want/need before you start down....

The ONLY reason that the EB is standard is because it is there to provided a load to the engine during active regens.

Say WHAT??!?!?!

That could be the craziest reason I have ever heard of for an exhaust brake. There is no load needed for an active regen to occur as it's a chemical reaction in the exhaust.

The exhaust brake is there to provide braking while decelerating and descending, period. It's saves the the service brakes and controls speed.

If the exhaust brake were to apply with fuel being injected BAD things could happen. EGT's would skyrocket, back pressure would be thru the roof, and who knows what other funky things would go on. This could be very bad under heavy power and light power.

All 6.7's, in pickups, came with the exhaust brake feature (It's a function of the turbo and not an actual exhaust brake like the 5.9's and other engines use). The C&C's had it as an option at first but it soon became standard. Even those without it just needed a software update.

All 6.7's have DPF's OEM, 3rd or 4th gen. There was never a non-DPF 6.7 put into the Dodge/Ram.

The 5.9 had a DIO (Dealer Instsalled Option) for an exhaust brake on the later 5.9's. I am not sure what year it became a DIO for the manual transmission (late 2nd gen comes to mind) but it was first offered for the auto's for MY06.


The Nissan Titan with the ISV 5.0 Cummins does regens like all other motors and it has NOTHING to do with the exhaust brake. Fuel is injected (either with an additional exhaust injector or the main injectors) that goes unbrunt into the DPF. This then increases the temp in the DPF to the point where it cooks the soot out of the DPF. Many diesel engines have DPF's and do regen's without an exhaust brake. There are plenty of pdf's and youtube video's on how active and passive regen work if you want a more detailed answer, this one was very general.

EGT's need to increase for an active regen to take place.

The EB only partially engages. Much like when the engine is at 0 degrees. To help the Cummins warm up faster, the EB partly engages as fuel is added to warm up the engine.
Works like a charm

But you have to turn the button on for quick warm up. The active regen cycle uses it when needed. That's why you hear turbo/EB hiss when active regen is happening.

Active regen happens by incressing EGT's & burning the soot out of the DPF. The DPF is not cleaned with a chemical.

Step back, do a little more research, and then come back to talk about regen and turbos.

EGTs are increased, for active regen, with fuel. This creates a chemical reaction, not a chemical.. They are different.

If the exhaust brake position was utilized with fuel applied above idle the EGTs would increase before the turbo mainly due to decreased airflow thru the engine. This would mean a higher EGTs down stream of the turbo but airflow would decrease and the pressure drop aross the turbine would increase which means a higher EGT drop across the turbine. (This can be seen with pre/post pyros. As the drive pressure increases the EGT delta increases).

For a "net reduction" regen, at idle, the airflow needs to be increased to get the fuel/heat to the DPF. This does not mean the exhaust brake is activated, it just means the VGT is doing what a VGT does. This is also why the rpms are increased.

Not all VGT's have a tight enough position to provide exhaust braking. You are confusing the VGT functionality with exhaust brake functionality, and yes they are different. Your VGT is always adjusting. It's position is adjusted bases on rpm, load, boost, etc...

An exhaust brake is absoloutly NOT needed for active regen, period. End of story. Above all it is not the ONLY reason there is an exhaust brake feature.

If you are saying there is a chemical reaction other than combustion, then i would ask you if it is a single replacement reaction, double replacement reaction, an organic reaction, a synthesis reaction or what type of reaction you are describing.

I do realize that there is some unburnt fuel that is carried through the exhaust gases provided by an after or late injection during active regen. This allows heat to be created later. But it is not this fuel that cleans the DPF. It is the heat/temp that "burns" the soot out of the dpf. It is not a decomposition reaction even. It is the temp that burns the soot. The active regen can be done without an EB. But i think it is more efficient with the EB.

 

[AH64ID]

You think there is combustion in the DPF?

Forget about the EB and active regen, it's not happening!

 

[Newsa]

Sizzling hot gasses late in the combustion cycle. And just a few sizzling unburnt fuel gasses still burning. An explosion in the DPF would blow it up

Modified the front box today and got it installed.


Tight on box in tow position.

OK, this weeks project was to get ready for a new trailer and different pin box( wider stock pin box, Mor-ryde or Trail-air) that was going to run into the modified front box when making turns. So I did mod #2 and shorten the rear of the box(upper level) 4"! Thanks again to the guys at Smiley's in Mount Vernon they cut off the one of the turned down lips on the lid and put a new lip on it 4" shorter. A zillion pop rivets later it has new short lid and box and back together and the lid slides nicely left of right like it should. Oh, and I can bend the slide release handle back the way it was!!

At this point the Heartland Bighorn 3575el is our first choice.

Bighorn uses Sailun LRG (all steel ply) tires, 7K axles, the Mor-ryde equalizer and correct track on all of their models. GVWR is 16K. Empty pin weight is 2435. Will have to watch pin weight! SNOKING

Friends don't let friends run ST tires!! :-laf:-laf

mine is the same. 1/2 tank takes 2.5 gallons.

Well the work on the box was not in vain. Today we sold the Cardinal and put money down on a 2017 Bighorn 3575el 5th wheel. Chris

Congrats on the new "Rollin Home" Chris!

I just googled it. Pretty nice unit!
