@@gooser__43 Yes, they are connected by gears on this configuration. The British had one that used rocker arms connecting the pistons to connecting rods to a single crankshaft. Complex but it worked. Look up Comber.
This one is 4 cylinder and its on 25%. Better consumption/heat conversion has seen in 3 cylinder, same brand, like the one they put into Ford truck, up to 55%.
The Opposed Piston 2-stroke design provided much fewer points of failure than in a conventional engine design: No cylinder head(s). No cylinder head gasket(s). No cam box / rocker cover gaskets No valves. No camshaft. No valve gear (cam followers, push-rods, cam timing gears, valve springs, keepers and collets, cam bearings etc). Six pistons, but only 3 cylinders and 3 diesel injectors. The Opposed Piston, twin Rocker Lever architecture also provided less than 5 degree conrod angularity at the pistons, so there was virtually no side thrust generated on each firing stroke. This meant the levels of cylinder bore and piston skirt wear, plus the related motoring losses (friction losses generated when the engine is running) were substantially less than all conventional design diesel engines. These combined qualities produced: High power density. High levels of mechanical reliability under adverse / overload operating conditions. Impressive engine life. Very low fuel consumption (.37 lbs per HP per hour).. Low overall operating costs. Known variously as: Rootes TS3.
Sure but what about connecting the 2 crankshafts? They can run like 10 gears on both sides and thats a lot of bearings to fail. Or if they run a chain, chains stretch and one could only imagine if that stretches even a fraction of a inch the timing would be completely screwed up and probably wouldnt run. Sure it doesnt have all the things listed above, but those arnt issues usually. From the outside looking in it seems like less things to go wrong but 1 new major thing that can go wrong.
It has been tried before though. Not sure this engine offers anything different to the RR K60 or Leyland L60. Still has piston rings crossing the ports, heavy crank gears, and very basic 'valve' timing.
You can also have very very big strokes without crazy piston speed at higher rpm (each piston covers half the distance). There was an opposed piston 2 stroke 3 cylinder inside an Ford truck at an autoshow recently. Could be configured for gdi or diesel (not both at the same time) and claimed the diesel could get about 40 highway mpg.
I loved going down to the engine room to see the Fairbanks do its start up routine. Its amazing how such a big engine runs so smooth. It really was not that loud in operation either for such a big engine.
The six cylinder, 1500HP variant that he talks about at the end of this video has recently been confirmed to be the powerplant inside of the newly announced "AbramsX" tank by General Dynamics.

@@graham2631 And they were light weight enough that they didn't last nearly as long as desired. They also slobbered oil. Light, high power, long lasting. Pick any 2.
Plenty of scope for experimentation. Number of cylinders, bore to stroke ratio, differing capacities for small car applications to the largest ships and power generation. The design seems to have a propensity for torque over horsepower and hi revs. Could a light compact hi revving short stroke version be designed for snow mobiles, jet skies, outboard motor boats and motorcycles?
Dear Cummins. Please remember. A company is built on, substantiated by, thrives & survives by two simple Facts. Supply & demand , coupled with customer satisfaction. Now Supply what we are demanding, and we'll be satisfied. Thank you
the V-12s we had in the USCG 82s were 900hp, the 903s we had in the 41s were 345hp, and had a 280hp V6 in a 30 utility boat... I wanna go back and play with these - WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA LOL
Turbines are so small I don't think it would compare. The current Abraham's engine is 1500HP and the size of a microwave. It burns a heck of alot of fuel though.
Horsepower doesn't really mean much for military, industrial, or commercial use. It's all about the Torque. Also, horizontal pistons always have issues with sufficient and consistent lubrication. Just ask Subaru WRX STi owners about the horizontal engine issues. Cummins could easily take their 6.7 and build it into a 1000hp+ reliable engine. Head stud it, larger turbo or compound turbos, larger injectors, more fuel pressure, that's about it. Also, emissions delete it. My Duramax is a daily driver. Been deleted and tuned. 520HP and nearly 1000ft/lbs of torque. Gets over 20mpg fuel economy.
These are dry sump and are more than twice the displacement of the 6.7 in a smaller footprint. You don't have to worry about this being hindered by emissions, it's the Gov't, they're exempt in the name of national security.
Horsepower is quite important. Horsepower is that rate of doing work and it takes a lot of work to move armor with decent speed. You seem to know nothing of duty cycle. 6.7 liters is not enough to reliably make 1000 hp for long periods of time with current technology. Your Duramax may make 520 peak hp, but it won't do that for long periods of time. If you want that much power for long periods then you end up in the 14-liter class of truck engines. Subaru boxers don't have lubrication problems. They have bearing area problems and some head gasket problems. The rod bearings are simply too small for long periods of high speed and load. If it was a problem of horizontal engines then Porsche would also have the same issues. They don't.
WTF with bearing issues my OMC small block v8 runs horizontal and oil injection, could your cum-a part for durajoke do that. i could get one from a junkyard and tilt to any position and synthetic 2 stroke oil injected into it. 6.7 is a poppet valved loop charged 2 stroke anyways which uses crankcase and turbo for scavenging. the oil is separate and is synthetic as it runs on split roller bearings. those small cummins can spin insane rpms, more than my omc v8 or detroit 8v92. 7 gals of xd-100 synth 2 stroke oil just got for my 8v92 2 stroke detroi from a boat dealer and its the best oil i used so far. i got my 7.3 [powerjoke poppet valved 2 stroke on amsoil dominator shell rotella combine to cut cost. it burn some too. My 7.3 powerjoke is on needle rollers SKF bearings and ticking over 330km! i got to keep the revs on it at times though.
Deutz did this a LONG time ago . Air-cooled Diesel on this design . VERY LOUD . Known as Knockers or Knocker-Boxes . Bulletproof . It's a Great design , then and now . Great to see the Mighty 903 is still around too .
Commer actually- 3 cyl 6 piston- TS3- or Tilling Stevens. Reliable? - questionable, but they got it semi ok towards the end. You had to keep them revving hard, don't lug them down like you''d expect to with a diesel...Quill shafts snapping was the usual malady, plus the sparks and flames from the exhaust!!
my dream 6x6 vehicle.... this Cummins motor, automatic Alison semi transmission, a mega beefy 4wd transfer case with high/low gears, 3 wide independent suspension crane axels all steering one pass through axle all with air lockers and disk brakes (hopefully portals too), high articulation custom fox suspension (maybe air suspension because of the weight though), bead locked huge wide tractor tires maybe the front tires on a john deere 6 series tractor (if possible a central tire inflation system), built like a hummer with the motor and running gear up inside the chassis so the bottom is completely flat, all body panels and skid plates made of ar-500 steel, bulletproof windows, a custom truck bed over the rear axles with a built-in huge fuel tank right behind the cab (all ar-500 steel construction), massive dual hexagon shaped front intake snorkels with cyclone filters, dual rear smoke stacks hexagon shaped with rain flappers, train horn with interior manual metering valve (Nathan k5la), raycore x60's mounted flush recessed just under the roof 2 each on front back and sides (they are mining lights basically bulletproof and put out 60'000+ lumens), 6 baja designs lp9's as the headlights lower bumper mounted, nice premium semi truck suspension seats in front and rear of the crew cab, warn hydraulic winch 30xl front and rear, massive thick tube brush guard bumper frame mounted. imagine a flat-fronted cab over the front wheels and the engine is underneath the rear seats or floor in between the front and first rear axle mounted as low as possible probably having to run the front drive shaft centrally overtop of the motor and then back down to the axle after. so yeah i spent way too much time making this comment hopefully Cummins reads this then builds it and gives it to me for Christmas lol :)
@@lllateralus Heavy? Its more compact then V shape engines or boxer engines. It's making more hp per weight than standard piston engines with head and valves....
Why would you think that? Just because its 2stroke? It's GDI (Gas Direct Injected) No fuel/air mix through the crankcase. Internal pressured oil system just like standard automotive.
Take an achates OP 2.7l and mount it in a custom stretched yamaha banshee. or buggy. or make a 1700cc OP from 850 rotax etec engine, that would make one nice sick trail sled!
Or like a Fairbanks-Morse engine on its side. Actually, for its horsepower and torque, this engine is not heavy, and it can be built out of the same materials that any conventional engine are made from. Because there is no valvetrain, there are 50-60% less parts, whats left is very easy to machine..

In Britain the COMMA Knocker engine was a 3 cylinder 6 piston type. The British also had Rolls Royce and Leyland opposed piston engines over a long period of time. The Deltic engine was a 3 crank triangular format 6 cylinder long with 9 in all and was line 3 V12s joined in a triangle at the head gasket faces. Little new apart from I expect the electronic common rail fuel system. I would like to know, is it a 2 crank geared engine or like the COMMA engine a single crank with large rocker arms ro operate the pistons? As I see the output drive is central.
@@andyharman3022 the engine in the video is not a comma knocker. Rolls Royce used a 2 crank design in military vehicles in the 1960s. Nothing new apart from may be fuel control.
@@rushymoto I never said the engine in the video is a Commer Knocker (better known as the Rootes TS3.) The output drive is central because it is integrated with the gear drive system that phases the cranks together.
I want to be able to purchase this engine, because there is nothing better than talking with the boys and saying: "You know, I dropped the Cummins Advanced Combat Engine into the ol' girl and damn is it going through drive shafts!!!" And boy does it look sleek, love the arrangement of the Turbos
Fairbanks Morse was one of the most famous builders of these sorts of engines, they were used in locomotives, surface ships, and submarines. Being a two stroke design, there is quite a bit more concentration of power for a given footprint, but historically emissions have been an issue. With modern common rail computer controlled fuel systems hopefully this can be overcome. That lower turbo outlet is so close to the fuel pump, though, there has to be some sort of shielding in between or it'll cause some issues.
I think one of the main points is that it balances itself out because it has two Pistons per cylinder when they fire at each other because they're opposed they opposing each other the Pistons supposed each other and then combustion like a boxer engine 2 Pistons per cylinder
I think they should have said the main part of this is to have two Pistons per cylinder so I'm not sure whether he's talking about a three cylinder with six Pistons which would be like a B6 engine or reset a 6 cylinder that would be 12 Pistons like a 12 cylinder engine because each cylinder has two Pistons
I could see this as a powerplant for a series hybrid-electric for both the Oshkosh Pro-Pulse equipped HEMMT A-3, and a follow-on version of the Striker using Pro-Pulse powertrain...
1000hp, but over 2000ft/lbs of torque is the thing that wasn't mentionned. So it could be coupled with more poweful electric generators and this produce more output for 25% longer. That is the beauty of opposed-piston engines. Aslo: no cylinder head, no roads, no cams, so much less complex system to maintain and easy to beef-up for say military usage.
Coast Guard Ice Breaker I was on had six FM 2000 hp opposed piston engines with 10 cylinders each. 810 Rpm flat out. Had problems with cracked cylinder liners, but new metallurgy can cure that. Maybe.
Hmmmm, how easily is it serviced? Durability ? ? Replace that turbine in the Abrams Main Battle Tank and save a whole lot of fuel? Also, this is a 2 cycle engine, right? Is there any hope of meeting EPA standards for use in commercial or construction vehicles? This sure looks like an Achates engine.
Damnit i could just burn holes through an old 855 block with a plasma cutter or laser, only intense energy and anger will form a a 2 stroke i guess! i have the port pattern from a yz250, cant wait to try it
Both Achates and Cummins have been quiet for the last two years..... Especially quiet on a SUV since the engine was demonstrated in a Ford pickup. Im beginning to think they've hit some major hurdles.... Pity....
@@TechnikMeister2 $170K is much less expensive than a turbine engine and cheap for a custom limited run engine too. Go price a new 500 HP Volvo D13 and see what it sells for. Also cheap for how much power it puts out. Go price a Cat 3512. These things would be much less expensive if Cummins was building a few hundred thousand of them.
Looks like a copy of the rotax engine opposed cylinder engines. If I remember right they made diesel opposed single cylinder engines for submarines in the past.
Some WWII submarines ran 4 Fairbanks-Morse opposed cylinder engines, I assume they were diesel. Why they chose 4 engines I do not know, but the USS Pampanito is still on display, and available for tours at Fisherman's Wharf in San Francisco. It's a great visit!
How heavy is this engine to support that much power? Interesting it's flat style similar to what Subaru's been using for many years, obviously with a reversed boxer configuration though.
Awesome Engine, but I get the impression that the Cummins rep does not know how to comfortably explain this motor in laymen's terms. Still, I would love to figure out how to mount this in my truck!
The boxer engine is an opposed cylinder, not opposed piston. They are COMPLETELY different engine designs! A boxer engine is nothing more than a flat V config engine!
They wont let us have them in our cars trucks semis because the engine would last a million miles before needing the rings swapped out. It would last forever and get 4x better fuel millage
MAP tractors (French) Simca. Used this design. Smooth and sorta quiet "not", but tre, tre thirsty and a breakdown was certainly a breakdown. Novel for sure, but ?!
Opposed pistons, a blast from the past and the wave of the future. I don't know why it has taken so long for this design to be rediscovered.

1500hp ... the same of the leopard 2. Are you thinking tho swap the abrams turbine with an 1500hp cumins diesel engine?
Oil injected 2 stroke here with roller bearings, just like the rotax 850 ETEC or my OMC rotaries!
When will this be available for the heavy truck market?
Never if the EPA has anything to do with it. I'd love to have on in my truck but as soon the emissions crap starts being put on it, reliability will go out the window like current engines. Stay safe out there.
Id like to know if such a motor would work in a marine environment. More engine room more power more distance = win win win.
They use jet turbines in marine use when they want to go fast. I dont doubt it could be used as a marine engine of some type though.
They got marine Diesel engines that make this thing look like a lawn mower
The English deltic was a triangular opposed piston engine used in marine and train applications.
@@graham2631 Thanks for the insight, not exactly what I was looking for but I learned something new.
@@graham2631 And they were light weight enough that they didn't last nearly as long as desired. They also slobbered oil. Light, high power, long lasting. Pick any 2.
Just wait till Gale Banks gets a hold of it.
gail stuff sucks. look into it no truck pullers will use his crap only wanna be truckers and city boy clowns
Wow 6 cylinder 12 pistons. That's insane. It's like Intel hyper threading
Its an OP 2 stroke!
I like that Cummins keeps it simple and clean cut straight forward not a madusa of hoses and pipes all over the place like Ford.
Are there any plans to sell this for the general public transport sector?
Plenty of scope for experimentation.
Number of cylinders, bore to stroke ratio, differing capacities for small car applications to the largest ships and power generation.
The design seems to have a propensity for torque over horsepower and hi revs.
Could a light compact hi revving short stroke version be designed for snow mobiles, jet skies, outboard motor boats and motorcycles?
Dear Cummins. Please remember. A company is built on, substantiated by, thrives & survives by two simple Facts. Supply & demand , coupled with customer satisfaction.
Now Supply what we are demanding, and we'll be satisfied.
Thank you
Love to have one fitted to my fishing boat!
The guy looks like diesel engine!
How come this is the only video of the new engine/old you of it?
the V-12s we had in the USCG 82s were 900hp, the 903s we had in the 41s were 345hp, and had a 280hp V6 in a 30 utility boat...
I wanna go back and play with these - WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA LOL
How does the power-to-weight ratio compare to a gas turbine engine with the same horsepower? Are there applications to aviation?
Turbines are so small I don't think it would compare. The current Abraham's engine is 1500HP and the size of a microwave. It burns a heck of alot of fuel though.
Horsepower doesn't really mean much for military, industrial, or commercial use. It's all about the Torque.
Also, horizontal pistons always have issues with sufficient and consistent lubrication. Just ask Subaru WRX STi owners about the horizontal engine issues.
Cummins could easily take their 6.7 and build it into a 1000hp+ reliable engine. Head stud it, larger turbo or compound turbos, larger injectors, more fuel pressure, that's about it. Also, emissions delete it.
My Duramax is a daily driver. Been deleted and tuned. 520HP and nearly 1000ft/lbs of torque. Gets over 20mpg fuel economy.
You are a fucking idiot!
These are dry sump and are more than twice the displacement of the 6.7 in a smaller footprint. You don't have to worry about this being hindered by emissions, it's the Gov't, they're exempt in the name of national security.
Horsepower is quite important. Horsepower is that rate of doing work and it takes a lot of work to move armor with decent speed. You seem to know nothing of duty cycle. 6.7 liters is not enough to reliably make 1000 hp for long periods of time with current technology. Your Duramax may make 520 peak hp, but it won't do that for long periods of time. If you want that much power for long periods then you end up in the 14-liter class of truck engines.
Subaru boxers don't have lubrication problems. They have bearing area problems and some head gasket problems. The rod bearings are simply too small for long periods of high speed and load. If it was a problem of horizontal engines then Porsche would also have the same issues. They don't.
they use roller bearings which are much sturdier!
WTF with bearing issues my OMC small block v8 runs horizontal and oil injection, could your cum-a part for durajoke do that. i could get one from a junkyard and tilt to any position and synthetic 2 stroke oil injected into it. 6.7 is a poppet valved loop charged 2 stroke anyways which uses crankcase and turbo for scavenging. the oil is separate and is synthetic as it runs on split roller bearings. those small cummins can spin insane rpms, more than my omc v8 or detroit 8v92. 7 gals of xd-100 synth 2 stroke oil just got for my 8v92 2 stroke detroi from a boat dealer and its the best oil i used so far. i got my 7.3 [powerjoke poppet valved 2 stroke on amsoil dominator shell rotella combine to cut cost. it burn some too. My 7.3 powerjoke is on needle rollers SKF bearings and ticking over 330km! i got to keep the revs on it at times though.
Häää ???
this is a very old system
In german is it a gegenkolben engine.
Ferdinand kindermann patend 1877
Blah Blah Blah..so why didnt yall build them?.. or the dozen other great designs college kids thought of..
@@venusreena2532 They did, Junkers put one in an aircraft (or two).
T64 same engine...and look the same 🤭
Opposed piston diesel engines have been used for many years, specifically in the Deltic diesel engine used in railway engines.
Deutz did this a LONG time ago . Air-cooled Diesel on this design . VERY LOUD .
Known as Knockers or Knocker-Boxes . Bulletproof . It's a Great design , then and now .
Great to see the Mighty 903 is still around too .
Commer actually- 3 cyl 6 piston- TS3- or Tilling Stevens. Reliable? - questionable, but they got it semi ok towards the end. You had to keep them revving hard, don't lug them down like you''d expect to with a diesel...Quill shafts snapping was the usual malady, plus the sparks and flames from the exhaust!!
So is it going to replace the AGT 1500 turbine engine in the Abrams tank?
Not really,for the Bradley and the wheeled combat vehicles the Marines and Army use.
my dream 6x6 vehicle.... this Cummins motor, automatic Alison semi transmission, a mega beefy 4wd transfer case with high/low gears, 3 wide independent suspension crane axels all steering one pass through axle all with air lockers and disk brakes (hopefully portals too), high articulation custom fox suspension (maybe air suspension because of the weight though), bead locked huge wide tractor tires maybe the front tires on a john deere 6 series tractor (if possible a central tire inflation system), built like a hummer with the motor and running gear up inside the chassis so the bottom is completely flat, all body panels and skid plates made of ar-500 steel, bulletproof windows, a custom truck bed over the rear axles with a built-in huge fuel tank right behind the cab (all ar-500 steel construction), massive dual hexagon shaped front intake snorkels with cyclone filters, dual rear smoke stacks hexagon shaped with rain flappers, train horn with interior manual metering valve (Nathan k5la), raycore x60's mounted flush recessed just under the roof 2 each on front back and sides (they are mining lights basically bulletproof and put out 60'000+ lumens), 6 baja designs lp9's as the headlights lower bumper mounted, nice premium semi truck suspension seats in front and rear of the crew cab, warn hydraulic winch 30xl front and rear, massive thick tube brush guard bumper frame mounted. imagine a flat-fronted cab over the front wheels and the engine is underneath the rear seats or floor in between the front and first rear axle mounted as low as possible probably having to run the front drive shaft centrally overtop of the motor and then back down to the axle after. so yeah i spent way too much time making this comment hopefully Cummins reads this then builds it and gives it to me for Christmas lol :)
I've got one of these in my smart car. Nice little unit
how many of these are required to carry a rosie odonnel?
"Sergeant we're not going to make it into battle, we've been derated to 5mph, we're a sitting duck"
No DEF in war
@@graham2631 I know, just shows how unreliable it is that military and emergency vehicles don't use it.
I would like to see a smaller marine & possibly aircraft version .
Philip Freeman -> marine application would be awesome. Much to heavy for any aircraft I
would think.
@@lllateralus Heavy? Its more compact then V shape engines or boxer engines. It's making more hp per weight than standard piston engines with head and valves....
Why has oppositional piston tech advanced recently?
If it's for a Bradley why the hell did they put an M1A1 on the thumbnail? M1A1's have jet turbines.
Need to hear this running!
Lets drop this in a new skidoo snowmobile
Haven’t heard boo about how this test worked out. It showed promise but I would like to know if excessive oil consumption killed this idea?
Why would you think that? Just because its 2stroke? It's GDI (Gas Direct Injected) No fuel/air mix through the crankcase. Internal pressured oil system just like standard automotive.
Of course, no hamsters were harmed in the making of this concept.
Fits nicely under the floor of a passenger train as well like the Hitachi Class 8XX running in the UK
Where's the Thorium Salt reactor?
That what they us to start it. 😯
So it like a German junkers bomber engine from ww2 cool
Take an achates OP 2.7l and mount it in a custom stretched yamaha banshee. or buggy. or make a 1700cc OP from 850 rotax etec engine, that would make one nice sick trail sled!
@@jlo13800 Might need to make it out of something much lighter than iron and such. Maybe Unobtainium. Sounds expensive though.
Or like a Fairbanks-Morse engine on its side. Actually, for its horsepower and torque, this engine is not heavy, and it can be built out of the same materials that any conventional engine are made from. Because there is no valvetrain, there are 50-60% less parts, whats left is very easy to machine..
@@burnerjack01 It could be made out of billet/die-cast aluminum 6061 alloy, cast iron liners sleeves, split roller bearings on the crankshaft, rods and and main's.
The Chieftain and Ukrainian Oplot use older engines of this design
But does it have a pump jet? And can it stay underwater for more than 14 minutes?🤔
Snorkel optional...
Can't wait to hear it
This is now on the 'Need' list!
Didn't Fairbanks do this a long time ago?
Since 1938...
they still do, the new trident OP 2 stroke over 5000 hp!
So it's 2-Stroke?
Yeah Detroit Diesels the world over just went HOOORAAAH
Yes OP 2 stroke uniflow scavenged!
How does it sound??
Like a 2 stroke diesel. That's what it actually is
@@DDBmaster Yes i would love to have one of these, got an 8v92 2 stroke v8 i tinker with, imaging this thing modified for some dune buggy project! i would run tuned pipe on it.
In Britain the COMMA Knocker engine was a 3 cylinder 6 piston type. The British also had Rolls Royce and Leyland opposed piston engines over a long period of time. The Deltic engine was a 3 crank triangular format 6 cylinder long with 9 in all and was line 3 V12s joined in a triangle at the head gasket faces. Little new apart from I expect the electronic common rail fuel system. I would like to know, is it a 2 crank geared engine or like the COMMA engine a single crank with large rocker arms ro operate the pistons? As I see the output drive is central.
It's a 2-crank design. You can see the torsional dampers on the front of the engine in the video.
@@andyharman3022 the engine in the video is not a comma knocker. Rolls Royce used a 2 crank design in military vehicles in the 1960s. Nothing new apart from may be fuel control.
@@rushymoto I never said the engine in the video is a Commer Knocker (better known as the Rootes TS3.) The output drive is central because it is integrated with the gear drive system that phases the cranks together.
I want to be able to purchase this engine, because there is nothing better than talking with the boys and saying: "You know, I dropped the Cummins Advanced Combat Engine into the ol' girl and damn is it going through drive shafts!!!"
And boy does it look sleek, love the arrangement of the Turbos
Now mount some tunes pipes on this 2 stroke gal, someone would call the cops.
How can I get one into my pickup?
Fairbanks Morse was one of the most famous builders of these sorts of engines, they were used in locomotives, surface ships, and submarines. Being a two stroke design, there is quite a bit more concentration of power for a given footprint, but historically emissions have been an issue. With modern common rail computer controlled fuel systems hopefully this can be overcome.
That lower turbo outlet is so close to the fuel pump, though, there has to be some sort of shielding in between or it'll cause some issues.
who cares about emissions when at war!
FM still produces OP engines at their beloit Wisconsin of plans. The latest design with Achates technical help is to four compliant.
I think one of the main points is that it balances itself out because it has two Pistons per cylinder when they fire at each other because they're opposed they opposing each other the Pistons supposed each other and then combustion like a boxer engine 2 Pistons per cylinder
I hope they will make some smaller versions of it.
Dear santa i have been good this year can i have this engine as my christmas present ill give you a plate of cookies and milk
Better fuel economy and smaller than the venerable Class 8, ISX15???
I didn't think the 903's were still in production.
I think they should have said the main part of this is to have two Pistons per cylinder so I'm not sure whether he's talking about a three cylinder with six Pistons which would be like a B6 engine or reset a 6 cylinder that would be 12 Pistons like a 12 cylinder engine because each cylinder has two Pistons
Why not Inline-6 ? I-6 is smooth and cheaper to produce, and also to maintain.
We'll see if those mpg numbers actually pan out given it has two crankshafts and thus much more rotational mass.
Not new Fairbanks morse already had opposed engines.
Can I put this in a boat?
I could see this as a powerplant for a series hybrid-electric for both the Oshkosh Pro-Pulse equipped HEMMT A-3, and a follow-on version of the Striker using Pro-Pulse powertrain...
1000hp, but over 2000ft/lbs of torque is the thing that wasn't mentionned. So it could be coupled with more poweful electric generators and this produce more output for 25% longer. That is the beauty of opposed-piston engines. Aslo: no cylinder head, no roads, no cams, so much less complex system to maintain and easy to beef-up for say military usage.
why don't you make these engines for people to swap in their cars and trucks?
Coast Guard Ice Breaker I was on had six FM 2000 hp opposed piston engines with 10 cylinders each. 810 Rpm flat out. Had problems with cracked cylinder liners, but new metallurgy can cure that. Maybe.
That would be a nice power plant for farm tractor or chopper
Yes there is a 750 hp 3 cyle, a 1000 hp 4 cyl and a 1500 hp 6 cyl OP 2 strokes!
ok.ok.ok fine when do i get to go to my dealer and pick one up? and how much?
A 2 stroke pickup, i would love that
Who said anything about a 2 stroke? It's a 4 cycle
It’s a 2 stroke opposed piston like a jump junkers aircraft motor or Fairbanks Morse
@@matttucker5786 when exactly did anyone mention that opposed piston engines are 4 stroke? No valves mate, no need for 2 extra strokes.
If you need to ask how much these engines cost, you can't afford it. I would love to get my hands of a 1500 hp unit.
Hmmmm, how easily is it serviced? Durability ? ? Replace that turbine in the Abrams Main Battle Tank and save a whole lot of fuel? Also, this is a 2 cycle engine, right? Is there any hope of meeting EPA standards for use in commercial or construction vehicles? This sure looks like an Achates engine.
Yes, a joint venture between Achates Power and Cummins.
Can I get this engine for my 1993 dodge W250 because why not
This should work really well
This is the Achates Power Advanced Combat Engine with a paint job.
Damnit i could just burn holes through an old 855 block with a plasma cutter or laser, only intense energy and anger will form a a 2 stroke i guess! i have the port pattern from a yz250, cant wait to try it
they have bean working together Achates are designing it but Cummins is the one that will be producing it.
Both Achates and Cummins have been quiet for the last two years.....
Especially quiet on a SUV since the engine was demonstrated in a Ford pickup.
Im beginning to think they've hit some major hurdles....
Pity....
Are we looking at a future Class 8 truck engine ? 20% better fuel economy than a VT903.
Not at $170k. Only the military can afford it.
@@TechnikMeister2 $170K is much less expensive than a turbine engine and cheap for a custom limited run engine too. Go price a new 500 HP Volvo D13 and see what it sells for.
Also cheap for how much power it puts out. Go price a Cat 3512.
These things would be much less expensive if Cummins was building a few hundred thousand of them.
I was going to say once the R&D and especially the tooling costs get paid down...
Anyone aware of the weight as it sits in the video?
Looks like a copy of the rotax engine opposed cylinder engines. If I remember right they made diesel opposed single cylinder engines for submarines in the past.
Some WWII submarines ran 4 Fairbanks-Morse opposed cylinder engines, I assume they were diesel. Why they chose 4 engines I do not know, but the USS Pampanito is still on display, and available for tours at Fisherman's Wharf in San Francisco. It's a great visit!
Rotax 850 etec made into 1700 OP 2 stroke, 360hp n/a and 780hp with turbo!
1:40 did he just describe what a normal operating piston is ?
*fairbanks has entered the chat*
Dude! Ya killed me! Hilarious!
How heavy is this engine to support that much power? Interesting it's flat style similar to what Subaru's been using for many years, obviously with a reversed boxer configuration though.
Nowhere near the same concept of engine! A boxer engine is an opposed cylinder. This is an opposed piston.
Two totally different concepts.
Awesome Engine, but I get the impression that the Cummins rep does not know how to comfortably explain this motor in laymen's terms. Still, I would love to figure out how to mount this in my truck!
So they made a diesel boxer engine?
The boxer engine is an opposed cylinder, not opposed piston.
They are COMPLETELY different engine designs!
A boxer engine is nothing more than a flat V config engine!
They wont let us have them in our cars trucks semis because the engine would last a million miles before needing the rings swapped out. It would last forever and get 4x better fuel millage
I want one of those turbos for my 5.9l Cummins!
mkae a 11.8 L 2 stroke out of (2) 5.9 cummins and dry sump feeding xd-100 2 stroke oil!
Hope they're better than what they used in the prostars and other linehauls
MAP tractors (French) Simca. Used this design. Smooth and sorta quiet "not", but tre, tre thirsty and a breakdown was certainly a breakdown.
Novel for sure, but ?!
When this engine is finally available i'm fairly certain it will be modified and installed in air crafts right away.
Probably too heavy for aircraft.
@@andyharman3022 Damn you're right it's 3500 pound.
