I don't drive the miles I used to drive so I'm going back to a gas engine. From what I read on line, all the HD versions of the Ram gas engines require premium gas, which makes it more expensive than the diesel fuel I'm buying now. Certain people are trying to force everyone to go EV but EV has a lot of problems right now. First, few charging stations; Second, chargers are not standardized across the country or in the industry; Third, the source of the lithium is not in the US or Canada but in China, Ukraine, or Afghanistan (but not being mined right now); Fourth, when the batteries wear out the disposal will become a major problem for all States.

Modern emissions systems means they'll still have a future. Could maintenance continue to increase due to those systems? Possibly. But you won't see diesel fading from the heavy duty trucks anytime soon. But likewise there are applications for these work trucks where gas makes more sense.

It's important to note that a gasoline engine would be the basis for a CNG variant. That is becoming increasingly important in the commercial truck world. Hydrogen will also be important in the future. Ford also has hydrogen engines in the works according to recent reports. That appears to be an admission that BEV may not be feasible for all applications. The hydrogen infrastructure is small, but it only requires water and electricity to generate. It also can be stored, meaning it can be generated using solar panels during the day or the excess power from nuclear plants at night. Hydrogen can be burned in an ICE configuration or used to power a fuel cell.

Personally I’m thinking my next setup will be powered by propane. You can order a Ford 7.3 with a propane prep package (not sure about the others from the factory). The technology that Roush & other similar systems use today means you can easily power your truck using both gasoline (on startup & when the propane tank runs empty) & propane. Propane provides the same amount of horsepower & torque and I can buy it for around $2 a gallon compared to 4 plus for gas & 5 plus for diesel. Another major benefit is your motor runs cleaner for far longer which means 300k to 400k miles should be achievable when running on primarily propane.

I suspect the Cummins is primarily being developed for Class 4-6 trucks since there's always been a niche for LNG-CNG-LPG power for those even if only from gas utilities (which is why GM offered gasoline V8s in the Topkick/Kodiak until it was discontinued at which point Ford picked up the option after many years of being diesel-only above the F350), and it's one that's likely to go a lot more mainstream.

[@andyharman3022]

Yes, I would like to see a gasoline-fueled Cummins 6.7 in the Ram. Cummins is not new to spark-ignited engines. They have a subsidiary in Clovis, New Mexico called Cummins Natural Gas Engines that has produced natural gas versions of Cummins diesels for decades. These engines are mostly used on irrigation pumps in the southwest. Cummins also developed lean-burn natural gas engines in the mid-1990's for on-highway applications. I was the mechanical development engineer on the 8.3L natural gas way back then, and really liked that engine. If Cummins does it the same as their natural gas conversions of diesel engines, they will put lower compression pistons in the shortblock, then optimize the valve facings and seat materials for gasoline/ethanol fuels. In the lower end, anything below the piston would be the same as the diesel, so the engine would last twice forever. Being able to eliminate the DPF, SCR, and EGR systems would lower the weight of the total powertrain, decrease cost, and improve reliability. Cummins could further reduce the engine weight if they switch the cylinder head material to aluminum. They haven't done that in the past on their natural gas engines, but it would make sense for the HD pickup application, where Ford and GM engines all have aluminum heads. The big question for me is will the engine be direct or port injected? I can think of pros and cons for either system.

I agree with you about DPF, SCR, AND EGR, but iron heads are better for heavy duty use by operators who are not the owner. One bad overheat and aluminum is done for.

Reference (NA) naturally Asperated. You are correct the 6.4L HEMI is actually 390.5cid but advised as a 392cid HEMI is a big disappointment in RAM 2500 and up. Reason is NA 6.4L in a RAM 2500 and up is only rated at 410hp. Yet that vey engine in a Challenger or Charger NA is rated at 485hp/476lb touqure. Now that would of been an excellent HD truck engine but was terribly detuned in the RAM. Even GM/Chevy 6.2L 378cid NA is rated at 420hp and a whopping 460lb torque. Get this, the 6.2L is available in the Silverado 1500 unlike the RAM 6.4L is not available in their RAM 1500. The 5.7L HEMI in a RAM is rated at 395hp @ 410lb torque. That is actually more power than a 5.7L HEMI NA both the Challenger, Charger and Chrysler 300M and Sport. Remember the old 340cid was only rated with a 6pac carborator setup was only 290hp but real time dyno after factory market rated at a mere 320hp but at the at 5500rpm or factory redline. In comparison the 5.7L HEMI NA 345cid only five more cubic inches than the old 340 produces in a RAM NA 395hp. That's what the power of a modern day HEMI can do. The RAM on average 5.7L NA at the flywheel actually produces on most DYNOS between 405~410hp as for insurance purposes factory usually under rates its flywheel hp numbers. RAM or Chrysler products are all over the place with its engine specs and what engines end up in what vehicle applications. Some just do not make much sense. I would not purchase the new hurricane twin turbo 6 HO for the first three years of production. By then it may be 2026 and fully electric RAMS will have been in production for two years and just maybe technologically even better then first though for EV production. Meaning powered by two 800hp or 1600 total hp AWD with much needed and & doable 500 to 700 mile ranges/full charge and full recharge cycles in a mere 15 to 45 minutes. Torque rating would be a frame twisting 1500 and up lbs torque. All that and you also get killer auxiliary power for other tasks and no more dealing with messy dirty fluid changes, no more expensive tuneups. No more exhaust systems and catalyst converters theft and parts repair and replacement. The benefits will quickly overcome the shock and sadness of the old ICE days. In all reality it's all about EV power supplies and convince that will come with range fear and full charge time. Certainly the standards of EV hp and torque will be celebrated. That 90plus percent of EVs will have a very welcomed as standard equipment smart AWD. The EV costs of purchasing and serving will come down to current vehicle by economic ratios affordability for all income levels just like our current vehicles of today.

You could have 1000 hp vehicle with a 3 cylinder, 40 hp motor with 180 lb/ft torque and 500 mile range.

Hydrogen has its issues too. Namely steel embittelment, and really low range unless very high storage pressures are used, and very low energy density.

So in that case you may as well just used natural gas or liquify it into either methonol or syn-gas at a price that is lower that hydrogen and simpler to adapt to current technology. Syn-gas if developed the right way is also carbon neutral. Hydrogen obviously can be produced carbon free via electrolysis from green sources.

And without many of the costs related to the diesel. Though it will still have expensive services if it truly uses the same bottom end. But cheaper fuel, no DEF. Though purchase price will most likely be more than what a current 6.4L is.

I'm just trying to wrap my head around how they plan to use a "similar" bottom end. The diesel is a long stroke, overbuilt for compression ignition. That's not what you want in an auto cycle gas engine.

@@AkioWasRight Most older inline 6 gas engines had much longer strokes than bores. Actually, comparing the current 6.7L i6 to older gas i6 engines (like the AMC 258), the bore to stroke ratio is very similar.

[@AkioWasRight]

@@Stuka87 They're both undersqaure, but 6.7L is still a longer stroke, with a 0.86 bore-stroke ratio in the B6.7 vs 0.96 in the AMC 258. Also, it's still a diesel with large bore spacing for robustness. That's just wasteful with lower compression auto ignition. Also, keep in mind that this isn't the 1970s anymore, it's 2022. Long stroke engines tend to produce more NOx emissions due higher compression. While some gas engines today do have undersqaure cylinders, most don't because compliance would be harder today with undersqauring, particularly for a large displacement engines.

@@AkioWasRight Stroke has little impact on compression ratio. Thats cylinder volume and piston/combustion chamber volume. A current pentastar V6 has 11.3:1 compression, it passes emissions fine. Most NA engines are high compression. Is the 6.7L block overbuilt for a gas online design, perhaps. But companies like BMW do this same thing. The B58 in a new Supra is a Diesel block used in a gas configuration because its very strong. Also, the Cummins gas engine could be Aluminum. Then its way lighter, and the extra beef is no longer really extra.

@@Stuka87 stroke has plenty to do with compression. What do you think stokre is for? To motion compressive pistons. You don't know what you're talking about.

Lightweight fuels (low molecular weight like cng, propane, maybe high temp gasoline) direct injected into high compression HD engines. Turbo even. If they can control the injection, I think this will be the future.

[@jlo13800]

yes Rotax 850 ETEC turbo 2 stroke way better than all this 4 joke stroke crap. 4 strokes suck! lets lay one of these 6.7 on its side and run oil injection, i cant wait to try that when i get time and im looking for a 5.9 to try it. the 5.9 could run in any postion with oil inejction.

Good idea especially if the i6 gasser was offered in the 1500. Cummins needs to try and fix the mileage losses the newer engines have over the older ones. My stock 99 24v cummins is getting 22mpg highway 15+mpg towing my 10k RV all-over the utah mountains (mostly dirt roads) the new trucks can't come close to that.
