In the end we found easier calling it something else, and we didn't come up with the 1-Stroke tag, it was suggested by an external ICE institution and we kept it because it sends the right message in terms of power and, to be completely honest, because it was catchy!

@stephenkeebler732 No you are incorrect and that makes your trolling look even stupider. This engine is precisely a “one stroke” because it fires one power stroke per piston for one revolution of the crankshaft.
It's just another axial engine, with a cylindrical cam instead of the more popular swashplate, in a two-stroke opposed-piston configuration. It will have all of the usual disadvantages of axial engines plus the bonus of the mechanical nightmare of the cylindrical cam with multiple roller followers, with the combustion characteristics of the two-stroke opposed-piston engines which have been built for almost a century. The variable phase difference between the induction-end and exhaust-end sets of pistons is the interesting feature.
and there are even more similarities between and diesel and a gasoline engine or a two stroke and a 4 stroke. Would you say they are al the same? All engines are similar and different at the same time. This one obviously needs development but if anything is more original than anything else I've seen recently.

Hi I can appreciate the better primary and secondary balance which is always the case with face cam or swash plate engines which is good. You have only shown the combustion part of this unit I will require a compressor for it to be able to run as is normal.for any opposed piston two stroke, I saw somthing claiming it to be a one stroke unit which it most certainly not. The nearest it could come to being a 1stroke is to have a combustion event on both sides of its pistons thus being a double acting two stroke.

Good point. It does use a scavenging pump which on the current prototype it's using 6kW when the engine is producing 92kW. Bear in mind that at the end of the day, in a conventional engine this work is being consumed by the pistons themselves, which are less efficient at pumping because they have not specifically designed for that. Thanks for your comment!

Very cool engine! Has there been any testing or consideration of using some kind of manifold charging like the old 2stroke Diesel engines for scavenging? Or perhaps resonance intakes and traditional 2stroke pipes? If the former, seems there’s huge potential for electric super chargers driven by the traction battery in a hybrid setup. I believe this was the favored setup in the return of the F1 KERS tech. OEM’s are starting to adopt it as well. Again, very exciting engine!
Question: one time? I say 3. Intske znd exhaust toggether is 1, but compression is separeted and ignition is separeted too. So 3 times. 1 time to ignite during the intake is very complicated...
"No system of energy can deliver sum useful energy in excess of the total energy put into constructing it. This universal truth applies to all systems. Energy, like time, flows from past to future" (2017).
The company does not mention a supercharger. Look like that it does not have one. I speculate that this engine simply use optimally tune exhaust pipe to assist the scavenging. Thus it will only work in a very narrow rpm band. The narrow rpm band may explain why this engine will be used as a EV range extender.
Approximately 20 years behind in video production but cool concept. Would love to see more real examples and documentation of the process - is there a running model yet? I want to hear it!

Great work guys When you combine an air conditioning unit and a boxer engine🤣. Is it possible to put a little pressure on the pretty wonder by means of a turbocharger or compressor? What about the exhaust emission values, so that the EU doesn't screw up your grandiose project? I'm waiting with bated breath to see what happens next.
Is this just another way of exploiting the Otto Cycle, or is it based on a different cycle? If the latter, might we see some details, or at least the PV and TS diagrams?
There is a lateral load on the piston where it pushes on the cam so the tendency will be for the bore to wear into an ovoid shape. The more torque required from the engine the harder the lateral load. In this design it appears the diameter of the piston is maintained for stiffness and short stroke are chosen to minimize this wear.
An independent 1D gas-dynamic simulation by the CMT estimated , at its best operative point, a brake specific fuelconsumption (BSFC) as low as 195g/kWh. This is about 22% more efficient than current equivalent engines. We will have empirical data by the end of 2023.
@@innengine-english Great news and running on hydrogen it will also be carbon neutral. And smaller and lighter means additional fuel savings. In the USA only California has hydrogen. It could also run on CNG which is 30- 40% cleaner.
@INNengine - English Hi, greeting from USA. I ove the engine design due to its simplicity and efficiency. Just a thought would it be better if each cylinder had 2 spark plugs on opposing sides? Also, when the 2 pistons are furthest from each other, not all gases are out unless there is a turbo that is pushing the air right? Also, this would be a great combo with hybrid powertrain (small lithium battery and 1-2 electric motors). Since with current engines, hybrid powertrains get 4 liter per 100km, with this engine it should way better than that. I would love to see this engine one day. What is the estimated date for mass producing this engine? Would love to buy one and install it on my hybrid powertrain.
Is this for sale? Because I'm eyeballing it for my KEI truck.❤ This would be a perfect little heart transplant. That'd be an awesome build. Variable compression!😍 That's a pretty little beast👍🤙😎
Interesting. I like it better than a Wankel. From my experience in rebuilding engines, I see a few areas of concern. 1. There would probably be more unburnt gasses left between the exhaust and intake cycle as it is not cleaned out as well as a typical ICE..... inefficient, more pollution. 2. Probably not suitable for high rpm because of awkward swashplates. 3. The end piece rotor slope seems more limited than the crankshaft 'throw' on a typical ICE.... less imparted energy. 4. The pistons would need to be slotted with guides to keep them from rotating.... engineering problem with both piston and cylinder walls. 5, The biggest difficulty I see is the tight tolerances required to keep the piston roller bearing on the 'cam' from 'chattering' as the piston goes up and down and causing premature failure. The slotted cam rotor plate, is a one piece item, subject to temperature variation, requiring precision engineering, with no means of adjustment later.
@@AugustoV8Cesar I have no idea what rpm it could make, only to say it seems to require cumbersome components which would probably be difficult to balance and would therefore limit it's rpm.... components which a regular ICE does not require. E.g., the swashplate and cam arrangement which move the pistons.... far more awkward than a typical crankshaft/connecting rod arrangement. Also, the surface contact area of a typical ICE con-rod bushing is probably 100 times more than the contact area of the equivalent components (rollers) in this design.... severely limiting it's life. I can't imagine this engine ever going 100,000 miles in a typical car. I still haven't seen how the pistons are kept from rotating in the sleeve. If groves/guides in the cylinder/piston walls are required, this just adds another level of complexity.
@@AugustoV8Cesar The characteristics of diesel fuel make it more suitable for slow rpm engines. Diesel fuel burns slower than gasoline so it is best utilized in a slower moving piston where more power can be extracted from it. I doubt if you could force a typical diesel engine to go up to 7000 rpm and destroy itself.... it would simply refuse to rev that high. Sort of like I could never run fast enough to destroy myself because my legs would eventually refuse to go any faster.

it is obviously a two stroke engine, as pistons have strokes, while the shaft has revolutions: the even number of cams, necessary to achieve dynamic balance of pistons, also works as a shaft speed reduction, which may be useful or not, depending on the application (not so much when driving an electric generator, but advantageous when driving a propeller. It would have been more transparent to show that a blower is necessary to feed the inlets. What I do not understand is the second part of the video, which looks identical to the first, just titled "3 stroke"!!!!!????? I would also be curious to understand the actual use of the "advance" adjustment of the second cam: this allows modification of compression ratio, while additionally moving the distribution diagram, exhaust vs. intake, not forgetting the possibility to adjust the boost pressure, which is not of immediate understanding with respect to operational requirements at varying loads. Maybe not needed in range extender application, but desirable in a car engine.
Not of the e-REX as prototypes would be too expensive to sell. We will be opening pre-orders for the REX-B, a 125cc simplified version of the e-REX aimed at off-road applications. Subscribe to our newsletter to get the latest info. Thanks!
the Australians have huge engines like this generating electricity. seem to me it's a two stroke. if it was a one stroke the piston would fire in both directions. which means the piston would be fixed on a shaft with piston rings on the shaft and piston
I believe the one stroke is when the crankshaft made a full 360 or 180 relative to the piston firing. After all, a two stroke for a traditional engine is when the shaft made the piston go around a few times before it can fire again.
Show us a video of going for a drive in it, not just clips of video. It's not too bad for an axial 2 stroke, but you had to fit a supercharger. Show us a rolling road test with figures.
Sorry to say.. its already been done.. & by the way.. 3 cylinders gives much better power density.. AND.. you havent a clue where the uniflow 2-stroke derives its efficiency gains over all other scavenging configurations.. your flat top pistons.. grossly inefficient
Thanks Errol, That is not the engine itself, it is a simplified simulation. The actual engine has active ignition prechamber technology and (good spot, by the way) the piston heads have a spherical cavity to favor both squish and swirl effects + uniflow scavenging. We do understand 2 stroke engines, but that would be a bigger conversation. The Center of Thermal Engines of the Technical University of Valencia has independently analysed our tech and they seem to be pretty impressed by it. Thanks for watching!
¿UNA INVERSIÓN CON FUTURO QUE PODRÍA HACERTE RICO CON POCO DINERO? Según la Agencia de la Energía de Estados Unidos, las reservas de litio para construir baterías se agotarán en 2025. Los ingenieros de algunas marcas como Toyota o Nissan ya vislumbran el futuro del coche eléctrico y, como dicta el sentido común, no será enchufable, sino que llevarán a bordo un pequeño motor de alta eficiencia, asociado a un generador para producir energía eléctrica. Un sistema que estará asistido por una batería más pequeña y liviana, que además no tiene por qué ser de litio. Con ello se solucionan tres serios problemas que presenta el coche eléctrico enchufable: el primero es la limitación de autonomía de las actuales baterías de litio, el segundo el largo tiempo de recarga de las mismas y el tercero es que las infraestructuras eléctricas de nuestras ciudades son muy insuficientes para suministrar la corriente eléctrica necesaria para recargar una gran cantidad de vehículos eléctricos, ello sin contar con que además, en las ciudades, no todo el mundo dispone de una plaza de garage para tener disponible un cargador para su vehículo. Los verdaderos entendidos en la materia opinan que el motor INNengine nace precisamente en un buen momento, ya que se trata de un motor que desarrolla una gran potencia, que pesa mucho menos que un motor equivalente convencional, que puede funcionar con hidrógeno o combustibles sintéticos y que además viene "como anillo al dedo" para construir coches eléctricos no enchufables, como el Nissan Qashqai e-Power, que con toda probabilidad serán los coches eléctricos del futuro.

it is obviously a two stroke engine, as pistons have strokes, while the shaft has revolutions: the even number of cams, necessary to achieve dynamic balance of pistons, also works as a shaft speed reduction, which may be useful or not, depending on the application (not so much when driving an electric generator, but advantageous when driving a propeller. It would have been more transparent to show that a blower is necessary to feed the inlets. What I do not understand is the second part of the video, which looks identical to the first, just titled "3 stroke"!!!!!?????
I would also be curious to understand the actual use of the "advance" adjustment of the second cam: this allows modification of compression ratio, while additionally moving the distribution diagram, exhaust vs. intake, not forgetting the possibility to adjust the boost pressure, which is not of immediate understanding with respect to operational requirements at varying loads. Maybe not needed in range extender application, but desirable in a car engine.
Its a 2 stroke engine. The only one stroke engine is a gun. where the piston doesn't return.
Now , if you could only get it to run on water ( using the hydrogen for combustion ) !!!
2 piston one cylinder..
2 ignition per rev
'COMSOL' physics and fluid mechanics software from SIEMENS could help in having a good BMEP in any type of engine...

If you are using any fasteners remotely similar to phillip style screws - I'm out!
is there any prototypes for sale
Not of the e-REX as prototypes would be too expensive to sell. We will be opening pre-orders for the REX-B, a 125cc simplified version of the e-REX aimed at off-road applications. Subscribe to our newsletter to get the latest info.
Thanks!
А как работает ГРМ я так и не понял
Do you sell it?
has one been made and run yet ?
Nope. And it never will.

the Australians have huge engines like this generating electricity. seem to me it's a two stroke. if it was a one stroke the piston would fire in both directions. which means the piston would be fixed on a shaft with piston rings on the shaft and piston
I believe the one stroke is when the crankshaft made a full 360 or 180 relative to the piston firing. After all, a two stroke for a traditional engine is when the shaft made the piston go around a few times before it can fire again.
@@WolfeSaber a one stroke a would be firing each direction so the piston would have a combustion chamber on both sides.
@@johnpublic168 Is something wrong with your grammar? Plus, do you know how strokes work?
@@WolfeSaber so your saying a stroke is 360 degrees
a stroke is from top to bottom then another stroke is from bottom to top that is a two stroke
@@johnpublic168 This engine is different, plain and simple.
Show us a video of going for a drive in it, not just clips of video.
It's not too bad for an axial 2 stroke, but you had to fit a supercharger.
Show us a rolling road test with figures.

"1 stroke"
Hi, just want to let you know that the channel Future Vision stole your content.
Now put it in an rx7
Sorry to say.. its already been done.. & by the way.. 3 cylinders gives much better power density.. AND.. you havent a clue where the uniflow 2-stroke derives its efficiency gains over all other scavenging configurations.. your flat top pistons.. grossly inefficient
Thanks Errol,
That is not the engine itself, it is a simplified simulation. The actual engine has active ignition prechamber technology and (good spot, by the way) the piston heads have a spherical cavity to favor both squish and swirl effects + uniflow scavenging. We do understand 2 stroke engines, but that would be a bigger conversation. The Center of Thermal Engines of the Technical University of Valencia has independently analysed our tech and they seem to be pretty impressed by it.
Thanks for watching!
It doesn't run.
¿UNA INVERSIÓN CON FUTURO QUE PODRÍA HACERTE RICO CON POCO DINERO?
Según la Agencia de la Energía de Estados Unidos, las reservas de litio para construir baterías se agotarán en 2025. Los ingenieros de algunas marcas como Toyota o Nissan ya vislumbran el futuro del coche eléctrico y, como dicta el sentido común, no será enchufable, sino que llevarán a bordo un pequeño motor de alta eficiencia, asociado a un generador para producir energía eléctrica. Un sistema que estará asistido por una batería más pequeña y liviana, que además no tiene por qué ser de litio. Con ello se solucionan tres serios problemas que presenta el coche eléctrico enchufable: el primero es la limitación de autonomía de las actuales baterías de litio, el segundo el largo tiempo de recarga de las mismas y el tercero es que las infraestructuras eléctricas de nuestras ciudades son muy insuficientes para suministrar la corriente eléctrica necesaria para recargar una gran cantidad de vehículos eléctricos, ello sin contar con que además, en las ciudades, no todo el mundo dispone de una plaza de garage para tener disponible un cargador para su vehículo. Los verdaderos entendidos en la materia opinan que el motor INNengine nace precisamente en un buen momento, ya que se trata de un motor que desarrolla una gran potencia, que pesa mucho menos que un motor equivalente convencional, que puede funcionar con hidrógeno o combustibles sintéticos y que además viene "como anillo al dedo" para construir coches eléctricos no enchufables, como el Nissan Qashqai e-Power, que con toda probabilidad serán los coches eléctricos del futuro. Y es que la ideología woke y su agenda 20-30 están muy bien para escribir ciencia ficción, pero cuando uno se da un baño de realidad, la tecnología y la ingeniería dictan otros caminos.
