Insider Source Reveals A LARGER Cummins Diesel and Gas Engines Are Coming!

[@coachvonyo]

Time for a very robust overbuilt single turbo straight 6 gas engine built for commercial. A new diesel is cool but the after treatment issues is why I've been dragging things around with a 6.4 for 6 years.

[@marcochavanne]

Former heavyline diesel mechanic here. I’m assuming youve never worked on a commercial diesel engine. You won’t be able to keep a solid front axle because they are much taller and overall bigger, and the Rams packaging can’t even fit a winch inside with the diesel engine as it is.

[@coachvonyo]

@marcochavanne we know they already fit a 6.7 straight 6 single turbo Cummins in a RAM, so they could fit a smaller displacement single turbo gas straight 6 as well. Possibly still minus the winch but the straight axle could obviously stay.

[@jamesg6071]

It’s called the 6.7 octane from Cummins it already exists

[@slidewide1999]

@@marcochavanneactually a winch does fit. There are companies marketing them now.

The DJT 533 CID 2 stroke inline 6 diesel used biodiesel as the fuel and lubricant and no oil changes are needed. Its can also start and run in either direction eliminating reverse gears. Its has 585 hp and 1860 ft-lbs torque.

[@jonathangeorgopoulos1097]

A heavier duty gas might be a perfect idea. Stronger, and more likely to last since you don’t have def and the electric system worries me how expensive that emissions system is to replace or repair.

[@daveperk]

Now all you have is the engineering of a straight six, large displacement, fitting it into a truck.

[@jeffs2809]

Be prepared, those gas engines will very likely have gasoline particulate filters. They've been common in the EU for quite a while and are on the Lincoln Nautalis SUV for next year in the US.

[@lucwilson1]

One thing you guys failed to comment on… Bigger displacement with less power = great durability. Some of those diesels are rated to go a million miles. Those small displacement high output engines just won’t last.

[@3wheelmannc860]

We need our truckers for sure. They do an amazing job everyday. More efficiency is a plus. The cost of diesel is far more expensive than it should be, and everyone should demand this to be resolved. We also need much better usage and infrastructure for our rail system...there is no excuse for rail not to be used better and more efficient for all our benfits.

I’m all for progress. I’ve owned a 2013 Cascadia for 3 yard now and dpf systems are a financial burden to fix. Just having to replace the one box and dpf filters is around $10k. You would think these components would be cheaper.

[@kmonto1971]

My 2020 2500hd Silverado with the L5P engine was a lemon. 52 codes since new, traded it off on a 24 F350 with the 7.3L. The emissions and electrical problems on that truck was horrible and Chevrolet techs had no idea how to solve pretty much all of the issues with that lemon. Two service managers at different dealerships told me to just "Lighten It Up" and save me all the headaches. Unfortunately, I didn't want to do that. Do miss the power but not the limp modes and being left stranded in 7 states.

[@cowboy3490]

There has been no news about a bigger B series engine (engine in the Ram) in Cummins. I've worked here for 20 years.

[@edgartaylor7421]

You should check out the S13/Scania engine in the new Internationals. It’s a diesel that does Not need an egr cooler or a VG turbo. Scania has had this engine in Europe for 10 years. They just came to the states.

[@DodgeDurango-de5po]

New DPF system? The more they over take the plumbing, the easier it is to stop up the drain

[@stanwilliamson2812]

That complicated system will cause major headaches for years until it gets figured out. Also my Kenworth salesman said the truck prices are going to go up by 20 to 30,000 whenever that new system is unveiled.

[@satansleftnut25]

Because of the warranty the EPA is forcing the manufacturers to implement on emissions systems.

The 2013 Thomas C2 school bus that I drive, with the 6.7 Cummins is rated at 240 hp @ 2400 rpm, it does maintain speed decently well with every seat filled pulling hills at full throttle, but it would be nice to not have to do that to stay at speed

[@jeffs2809]

Biggest difference on the Commercial engine side of things regarding HP, is that the 9 & 10L engines are governed to only 1900-2200 RPM depending on use/power selection. The 15L is governed down to 1700 rpm. Even the commercial 6.7 is only running up to 2600.

[@redman2805]

My x15 isn't governed down to 1700 rpms mine is governed at 2100 rpms it's all in the computer and who set the ECM settings

[@JimmyShields-z2h]

Straight six diesel is most efficient engine but i know truck drivers who like Scania V8 not only have power up hill but have weight in right place to pull trailers. Cummins with gasoline straight six will good for Australians with Ford sixes get hard to get. Interesting if Cummins has revised 5.0lt V8 diesel that was in Nissan Titan?

[@Kahless00]

A gas turbine is the most efficient engine.

[@17_300KTM]

Can’t forget that Kilowatts of electric heat comes at a cost and will take a noticeable amount of HP from the engine to turn a generator. If you compare a gallon of diesel burned in an engine preheater or cab heater to using that same gallon of diesel to run a combustion engine to convert that energy from mechanical to electrical then to heat I’m not so sure you will see a gain in efficiency. I’d like to see it in action though. Time to heat the process in the after treatment might be a gain yes and at least the generator will add load to the engine during warm up on cold starts and get everything warm quicker. This is kind of like charging an EV from a grid that was generated from coal or burning fossil fuel and saying you are saving the world.

[@milstar71]

I keep hearing that torque is king but that's not exactly true, duty cycle in my opinion is just as important or even more important. 6.7 powerstroke is a good example on a pickup it does well it doesn't see the load like it would see in f550-f750. I see a lot of engines catastrophically fail in f550 in as little as 30k miles because it just can't handle constant load factor in this application and that's where you need an engine with larger displacement and structurally heavier engine.

[@regnar19881]

Think I'd rather invest in older vehicles versus these new ones which are way over-engineered. CARB is a joke.

[@DillonPrecisionFan]

No more post injection event to heat the DPF will be a big improvement!

[@jeffs2809]

I would expect a 7th injector in the exhaust rather than relying solely on the electric heater. Also, I'm pretty sure those use a 48v electrical system to support the current required for the heater. I wonder if Ram/Cummins would go to a primarily 48v architecture or keep it primarily 12v and only use the 48v for the emissions. EPA rule requires significant reductions for Nox at idle and low load, I believe that's where the electrically heated dpf/scr is coming into play.

[@jamiegrace9662]

California should accept electric only deliveries and see how that goes for them.

[@billn911]

Why doesn't every engine come red? This is against the ISO rules. Red = Cummins, Yellow = CAT, Orange = HEMI, Grey=Chevy and Cracked Blocks = FORD

[@andyharman3022]

I still haven't adjusted to Cummins change from red to blue. It really messed things up because Valvoline had the Premium Blue diesel oil that they developed with Cummins.

[@livingtheamericandreaminth1872]

I don't see the 6.7l being phased out. I see the 7.2L being a additional diesel option to choose from.

[@jeremymurphy7320]

I'd be thrilled if people stopped calling their Ram diesel a Cummins. "Let's take the Cummins" No. Take the Ram. Don't use the Duramax, either. Use the Chevy / GMC. Or use the Ford. Thankfully Power Stroke is kind of cumbersome to say or I'd be complaining about that. None of this matters, just my somewhat pedantic take on diesel bros. P.S. I love my '96 Ford F250 with the good ol' 7.3 PSD so I'm certainly not anti-diesel.

Every comment here trying to defend the EPA is just illustrating the problem. Were not in f-ing china and 99% of us aren't in LA. Actions and requirements needed in those places are not needed in Dillon Montana or Bainbridge Ohio, but because the EPA is a one-size fits all tyranny, everyone suffers. Big government solutions ALWAYS create more problems than they fix and they ALWAYS suit the needs of special interests rather than the average American citizen.

[@andyharman3022]

Any heavy-duty pickup with more than 385 hp, 850 lb*ft of torque is just for bragging rights. The EPA has ruined diesel engines for operating economy with their ridiculous NOx and particulate regulations. The required systems have increased initial cost, increased maintenance costs, and hurt fuel economy. Diesel engines have become uneconomical to operate, which is why Cummins is developing a heavy-duty gasoline engine. The fuel and emissions systems will be much less expensive than modern diesels with the alphabet soup of aftertreatment systems.

[@gravityfab]

I’m with you, but for Devil’s Advocate’s sake, if I had it my way I would want Ram to build the most reliable truck on the market and stop worrying about all the luxury garbage. The current may not be biggest in class but the cab is plenty big, and it does have advantages when you consider parts availability, as well as the cab being steel and not aluminum. I’m not a fan of aluminum cabs and a bigger steel cab would weigh more. If Ram kept the cab the same and just focused on efficiency and durability I would be just fine with the current configuration.

[@briancavanaugh7604]

@@gravityfab I will also add to these GREAT points that I don't want the redesigned cab to happen under little carlos and company at stellantis "leadership." Doing the redesign under the current "leadership" is almost a guarantee that every possible corner will be cut and that the thing will likely be complete trash. I too would like an updated cabin, mainly the bell housing in the front passenger foot well, but I would be more than willing to wait till that (unt carlos is gone and stellantis is nothing but a horrible memory.

@ you’re not wrong, Stellantis is the master of hackery. As far as the footwell bulge goes, it doesn’t bother me. I’m good with it since it’s there for the turbo downpipe and there’s no way to get rid of it without going to A: a different engine config (no thanks) B: a longer hood (not interested) C: a smaller diameter downpipe (nope).

[@gravityfab]

@@jamesonpace726 fancy may sell to some, and the truck market is definitely going that way, but there’s a large group of us who buy trucks for their utility and rely on them day in and day out to get us past the repair shop and fuel station. 15 years ago that cab was huge, it’s our own discontent that has made trucks more expensive and less reliable.

[@jeffs2809]

If it has an SCR, you;d still need to buy DEF. Nox limits are getting dropped a LOT for EPA27, ~80%. Also, requires manufacturers to increase security to prevent tampering and increases the serviceable life of emissions components (DOC, CAT ,DPF, SCR) by a LOT (Which, I believe, will increase prices to compensate for warranty coverage).

[@AkioWasRight]

An electric DPF won't necessarily be for commercial applications only. Actually, if the system works well, it could lead to the comeback of non-commercial diesels.

[@P-J-W-777]

Yeah why do we have these low horsepower diesel engines when Scania produces much higher horsepower engines and does not need to utilize an egr system all because they are running higher compression. They run higher horsepower because they are running V8 diesel engines laying down factory power that the inline 6 engine simply can’t reliably. If you’ve driven in the hills or mountains with just a 65,000 pound gross weight you know that the 600 hp still sucks.

[@gravityfab]

If you know about towing 65000lb (or heavier) you know that torque is king, especially in the hills.

[@P-J-W-777]

@ Duh! They still don’t make crap for torque when compared to other diesel engines on the market especially overseas. I have a little over a million miles between hauling and towing with about a 1/4 of that being heavy haul. Not including the fact that I’ve been raised around trucks since born and remember the days when we had big V8 diesels that could really lay down the power.

[@gravityfab]

@@P-J-W-777 wow, since birth? Amazing. There are 4 main categories any engine designer should take into consideration. Durability, Efficiency, Emissions, and Power. Technology doesn’t allow you to push the limits of all 4 at the same time, as I’m sure you know, being a heavy haul prodigy and all. Sometimes you have to make a compromise in one category in order to appeal to another. In my experience I will gladly take efficiency and durability over gross power, but the government here in America has higher emissions standards than the rest of the world. Cummins may produce conservative torque numbers but you don’t get to the top of the diesel market on power alone. But you know all that, with your unequaled experience and knowledge in all things heavy hauling.

[@P-J-W-777]

@ I never claimed to be a prodigy (nor would I) because I’m still learning to this day and the day you stop learning is the day you fall behind. With that said you are the one that assumed I had no knowledge of the diesel industry which is why I gave you a small little background. I’m not some keyboard warrior posting 💩 for my own amusement. Fortunately we’ve built some pretty amazing motors after which have been very reliable and making more power over their factory rating. We still have a couple V8 Cats that I’d put up against any modern I6 factory engine while still maintaining decent fuel mileage. We don’t run them anymore due to that good old government EPA BS. I’m going to assume you either work for a manufacturer or for a fleet company simply based on your response. The Scania V8 would pass emissions tests here in the US and do so without the need of the EGR system. Why don’t you go do some research on them yourself na then hopefully you’ll understand.

[@AkioWasRight]

Because emissions are different in the US and the EU. Higher compression can result in more horsepower and efficiency, but it also results in more NOx. NOx emissions standards are very convoluted and difficult to comply with, particularly for diesels.
