Firing every repetition is a stroke a 2 stroke fires every cycle but only 1 cylinder is in use vs 2 for a single explosion. That's my take on it anyway.
From a cycle point of view it is certainly a 2 stroke engine. The issue with calling it a 2stroke, we found, was that people would intantly assume things like it run with oil in the mixture (which it doesn't), or that the exhaust port closed after the intake (which again, it does not), or that it could only deliver so much power. 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! Thanks!

@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.
É um motor 1 tempo porque faz admissão e escape ao mesmo tempo, quando um sobe empurrando a queima, o outro está comprimindo a mistura, num mesmo ciclo e cada movimento gera uma rotação, incrível.
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. I am shure you will be able to improve on its power as 20 horse power is only half of what a single cylinder yamaha is caperbull of, usually more cylinders means more power what kind of BSFC are you seeing after factoring in the power required to run the compressor Good luck hope to see more in the future
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!
How does this differ from the duke engine? The duke engine had very poor efficiency. That said, the fact that it is an opposed piston engine, plus it uses rollers is very interesting and nice to see.
@@_aullik Yes. but its the doubling of the movable work boundary and the power stork per piston movement that are the power and energy grabbers+efficiency. trust me this is the engine of the future.
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!
1932 Junkers Jumo 205 diesel aircraft engine One of the first opposed-piston engines was the 1882 Atkinson differential engine,[7] which has a power stroke on every rotation of the crankshaft (compared with every second rotation for the contemporary Otto cycle engine), but it was not a commercial success.[8] In 1898, an Oechelhäuser two-stroke opposed-piston engine producing 600 hp (447 kW) was installed at the Hoerde ironworks.[9] This design of engine was also produced under licence by manufacturers including Deutsche Kraftgas Gesellschaft in Germany and William Beardmore & Sons in the United Kingdom.[10] In 1901, the Kansas City Lightning Balanced Gas and Gasoline Engines were gasoline engines producing 4-25 hp (3-19 kW).[11] A 1914 Simpson's balanced two-stroke engine Design

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.
"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).
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.
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...
You should add that to the animation. I'd love to see how the intake air is pushed into the combustion chamber. It's a very elegant engine, but I was wondering how the intake worked.

Der Erfinder nennt ihn 1-Takt-Motor weil er die Arbeitstakte mit der Wellenumdrehung in Verbindung bringt. Für mein Verständnis ist die Funktion mit einem 2-Takt-Motor vergleichbar. Aber: wie kommt das brennbare Gemisch in den Verbrennungsraum? Beim 2-Takter erfolgt dies durch die unterschiedlichen Druckverhältnisse im Kurbelgehäuse. Eingeblasen wird dies durch die Überströmkanäle. Dieser Motor hat so etwas nicht. Muß er durch Überdruck befüllt werden?
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.
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?
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.
What RPM range will this engine operate at, is it most effective at a narrow RPM range just like the opposed piston 2 strike diesels? I was wondering why no one was making a 2 stroke opposed piston petrol engine.... All the 2 stroke opposed piston engines I have ever seen was diesel and it should be possible to make a direct injection petrol engine the same way.

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.
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.
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.
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.
Very interesting. How do you prevent oil to scape from exhaust port?
I watched another post which says that no oil is used

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.
Can it make more than 10,000 rpm?
'COMSOL' physics and fluid mechanics software from SIEMENS could help in having a good BMEP in any type of engine...

斜盤機関で対抗ピストンエンジンか〜
コレは面白いw
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.
@@WolfeSaber9933 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?
@@WolfeSaber9933 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.

Do you sell it?
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!
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!
Hi, just want to let you know that the channel Future Vision stole your content.
"1 stroke"
Now put it in an rx7
has one been made and run yet ?
Nope. And it never will.

¿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.
