The True Range Extender
HTML-код
- Опубликовано: 11 сен 2024
- At INNengine we believe that the future of transportation will be hybrid, in the form of vehicles with a range extender ICE.
Such engines must have 3 main qualities:
-Compacity
-Efficiency
-0 Vibration
With this in mind we created the e-REX: the first engine designed from scratch with a range extender mindset.
The future is eclectic, the future is INNengine e-REX.

This needs more attention
its was.. 40yrs ago
Agreed, also this is first generation so durability will be questionable for maybe 2-3 versions into actual day to day r&d
Basically, a swash plate motor but I can't see why it is being called a "One-Stroke " Motor.
A one-stroke motor would only fire once and then do nothing. Opposing pistons have been around since the Napier Deltic engine, a 2-stroke, 3-crankshaft, diesel motor used in Trains and generators.
ruclips.net/video/V8dJrnADE4Q/видео.html
Still, combined with an electric generator, this is a great solution for hybrid vehicles.
It would be a 2 stroke, I don't think they understand how a 2 stroke actually works. Up and down are 2 strokes, I think they are misunderstanding the concept of how 2 and 4 strokes function.
'm guessing it uses an early exhaust timing or higher exhaust port along the cylinder, in order to use the pressure from the hot combustion byproducts to mostly evacuate the cylinders, then shortly after, opening the intake at the opposite cylinder end, which would likely be forced induction boosted - through a turbo or supercharger, to push out the rest of the exhaust at bdc, then closing both off and injecting fuel at high pressure as the pistons are at or nearing tdc. It would work, but rpm range would be strictly dictated by the speed at which the pressurized exhaust could flow out of the cylinder. Timing would need to be very precise, sensors would need to be very accurate. Too slow and there would be pressure spikes traveling up and down the exhaust and intake tubes, too fast and the intake would be fighting to push pressurized exhaust out, still combusting as the pistons try to come together again. This would be fine if it's only being used to power an electric motor, you could keep the engine running at a narrow rpm range if you coupled it to to a bank of batteries and/or capacitors. They could be charged while idling or driving at a stable load, in order to have extra power during acceleration. What I'd be most concerned with is the uneven heating of the intake versus exhaust ends of the motor, and how to properly keep all the swinging metal lubricated evenly and effectively. Also how to get it started without the rpm being too low, possibly damaging the super or turbocharger vanes, and how to get your forced air spooled up right away to enable proper cylinder exhaust evacuation during the start.
They are very open and have explained many times that it is a two stroke and the reason behind the tag 1 stroke
@@hoymejorqueayerrgr5444 It's easy to criticize and without taking 2 mins to learn what these people are doing.
@@felipeberruezoyes, could you explain us your point view?
Why does this motor have only one stroke?
How would be your lubrication system?
How would this motor work its side force with the wall of cylinders?
And there would be a lack of harmony between the base of pistons and the disc that makes the time of cranckshaft?
@@hoymejorqueayerrgr5444 Explaining why you are lying about you technology doesn't make it any less wrong. It reeks of misinformation for hype like potential scam artists use to generate hype and get investors. They should not call it that imo. If the engine is a great design and not just a great concept, it will get media attention even without lies.
Its a 2 stroke not a 1 stroke .{1 stroke for combustion & exhaust} and {1 more stroke for intake & Compression} .So my math says 1+1=2 stroke. But still a awesome design and type of engine .And a awesome way to bring 2 stroke back to new generation motors .And if its as sufficient as INNengine says it is , then it would be perfect for ultralight aviation .Smaller so less metals to cast and machined ,and less working components then your normal 4 stroke engine. And my favorite thing about this engine is that you can change the compression easy. It would be much easier & cheaper to use this engine in a AWD mid engine vehicle .So its a 2 stroke engine that doesn't use 2 stroke oil & your ordinary crankshaft+connecting rods so its a opposed 2 stroke motor .I cant wait till someone does force induction on this motor ,or a turbo diesel model.
hydrostatic transmission, we have this on our Kubota tractor. Basically a hydraulic swasplate motor.
Fascinating concept. I hope it comes to fruition.
It alredy works : tested on a MX-5 Mazda.
@@netshaman9918 but max-5 Mazda is from 1998
With the thrust bearing load on this engine I do question it's expected lifespan.
I love this consept from India and sereusly this is very compact and other side is very simple I'm really oatting when it lunch i wish one day this engine will change the world.
(And I also wish on my next life when I born i have enough money to study about all kind of engine I love it thanks for read good luck

I couldn't understand
Very good job... Congratulations!!!
This seems like quite a breakthrough in ICEs. I'm excited to see where it goes but am curious as to how well it will hold up over time and what drawbacks it has compared to traditional 4 stroke motors.
This is quite a breakthrough and yet so small but very powerful I definitely want too see more on this project.
range extender generator indeed! this is amazing !
How about the abrasion problem at the contact point between the cylinder and the curved plate.
We solved it with metallo-ceramic at the apex of the Wankel engine rotor; by the time the Wankel engine was ready, the market didn't wanted it anymore.
How many km a car with your engine will fare?
The initial Wankel lasted 50k km vs 300k km of a piston engine, thus failed initially.
Great innovation BTW, thanks for the video ..
this is the first I've heard this claim of the Wankel contact point being solved. Please share data
@@larrymar19 me too :)and doesn’t matter BTW that they burn oil in almost two stroke rates :)
"the contact point between the CYLINDER and the curved plate" is uncritical, a plain gap could be there, and it wouldn´t matter at all... It isn´t a contact-point subjected to combustion-chamber-pressures, where it´d have to be air-tight. It doesn´t have to be air-tight for any reason, so, leaving a gap there is the best solution, possibly.
The contact point between the PISTONS and the curved plate, an the other side, are critical, and may have too high friction, but the pistons ride on (frictionless) rollers (with bearings themselves) upon the swash-plate
By this logic, a 6 cylinder detroit was a 1/3 stroke engine. All they've done is reorient the crankshaft and use that to count.
This is a 2-stroke. We count the strokes by how many events happen per piston. This has a compression stroke and a power stroke, therefore 2 strokes. We do not count strokes by how many power strokers there are for the entire engine per revolution. If we did this, then a normal v8 would be 1-stroke because it has a firing event per half rev.
Now do it in a diesel config and get even more power and efficiency
that would nullify the emission benefits of electric
Range extension is great, why EV manufacturers (especially those from well established, well funded companies like ford or hyundai) didnt think to incorporate them from the jump is beyond me. Where i live and work the nearest charging station is over an hour away. And those living in towns / small cities who dont have a driveway and have to park on the street have 0 options for charging an ev. You cant run an extension cord out the front door to your car and hope nobody screws with it or trips over it and sues you.
Range extenders are a mixed benefit/cost. For short trips you've got dead weight doing nothing but reducing efficiency. For medium trips the generator may only be the same energy density as good batteries, so you get radically increased complexity with the same range as you'd get adding extra batteries. For long trips it would be a real benefit, but it would take a long trip to be a worthwhile benefit due to the added weight and increase in complexity/decrease in reliability.
This engine concept started for the first time in 1964 in Aiud, Romania
The engine was designed by Mr. Arama, Mechanical Engineer ,
Does it actually work though, in theory sounds great
i didnt see them start it either.
In our Spanish channel we have videos of the engine in both a car and on an aircraft. We will upload them to this channel too. Thanks!
We find here a great idea and a very confortable 4-cylinders realization. We hope to find it in a light spanish car very soon! it can also fit the 2CV from Citroën car or fit their light SUV Oli-project ...
Must build a large one.❤
Then make it run on race fuel & stick it in a motorcycle 😂
@@InsaneDad that's the spirit 🤣
But, honestly. I feel that people would really get pumped about it if they built a high performance model. Namely American use. Don't corner yourself to a specific market with ev. I feel like as a stand alone power plant, the hp seems to be there. Honestly, maybe even side by sides. Boat motors, sky's the limit.
Geniaal
Damn I'm into rc planes and want one but also dirt bikes, these would take over in dirt bikes with so little vibration and power to weight ratio
I would like to see it in small gas cars, I had an EV and went back to gas, the whole waiting for the car to charge is not for me and the range wasn't very good either.
❤❤❤
there is no such thing as a 1 stroke engine. this is simply a 2 stroke engine with the traditional crank and piston rod reconfigured to operate on an eccentric cam
Yes, this is a two stroke engine but a one stroke engines do exist - they're called jets!
This is a breakthrough !
I take issue with the terminology used. Firstly, this is not a one-stroke engine. The fact it has opposed pistons that move each move forward and back precludes the use of the term one stroke. One stroke means one action, one time. The absence of a crankshaft does not eliminate piston strokes. What you built is a two-stroke non-crankshaft engine. Btw: It also still has four phases. Intake, compression, power, and exhaust. How are you lubricating the piston rings?
The beef I have is with how you described having variable compression! You said that when more power was needed, the compression was lowered; when more efficiency was needed, it was raised. ICE does not work that way. Higher compression engines are generally more powerful and efficient, while lower compression engines are the opposite.
You must also develop a variable octane fuel to get variable compression to work correctly. Lower octane fuels burn faster than higher octane fuels. If you use a lower octane fuel in a higher compression engine, detonation will occur because it will ignite too soon. If you retard the ignition timing to compensate, you lose power and efficiency. If you use high-octane fuel in a low-compression engine, you lose power and efficiency because it burns slower and will not be completely burned when the exhaust phase arrives, resulting in higher emissions. Advancing the ignition timing can help compensate for the higher emissions but not the loss of power and efficiency.
I see no practical reason for variable compression unless the sole purpose is to allow the owner to use less expensive lower octane fuel when not using the vehicle in a manner (towing, hauling) requiring more power. It also adds unnecessary complexity to the system.
I see a compression stroke followed by power stroke, there for this is 2 stroke engine
Whats the difference with this engine and every other swashplate engine thats come before it?
So Why not use it in series with a electric motor, in a true hybrid, if it's as good as 2l inline ICE?
post a video of the motor in action. we want to hear how it sounds
There's video of it in the bench, a car and a large model airplane. Bear in mind in those it's still using just "open exhaust", meaning it's yet to be refined. Thanks for watching!
@@innengine-english link?
hate to tell you this but that is two strokes not one. This is not a new design, the acadies engine is basicly the dame but with cran shafts. I would also add dimpling to the pistons it will increase thermal eff. and decrease NOx and CO2.
I want details on the engine not what you think it should be applied to. I can figure out its uses all by myself and probably exceed what you think should happen.
could we put it insteal of our engine?
I like the design. 500CC should easily equate to 200 Horsepower if this is truly a one stroke engine.
It's not truly a one stroke engine. Even the company admits this. It's an opposed 2 stroke engine.
Can you do it with just 3 pairs of cylinders instead of 4 pairs of cylinders?
Yes, and even more on larger engines.
this is awesome!
I'd like to see this in the real world... 1 question, looking at the cutaway thus is by all definitions a 2 stoke engine atleast, it has a compression stoke and a expansion stroke just like any 2 stroke engine...if your going to say it's a 1 stroke then you have to say a rotory is a 1/2 stroke, it has a 1 and a 1/2 expansion cycles per rotation of the, or for every 3 rotation of the "crank" shaft is about 6 expansion strokes...
Perhaps all true, but they have made no proper arguement for this being a great RE engine. Numbers please. I'm thinking tiny Wankle personally.
When can I buy it?
Do you sell this? Is it already finished?
Wait a minute… you said it’s equal or stronger than a conventional 4 stroke engine. 2000cc is 2.0L. My truck is 5.0L 21/2 times that size to get to 5.0L(?)- that’s close to the v8 powerhouse i already have … and I know and can work on (it’s a Ford) this one. How about wear and tear? Will last twice as long?
motorcycle power plant? light sport air craft? personal watercraft? im thinking these could power any old volkswagon air cooled vehicle and be way cleaner and more powerful . two thumbs up?
someone needs to put this in a model T ford and compare the performance.
Diesel gets better range to weight?
Is there any hydrogen version?
ill take one
And all of a sudden my wife is now interested in engines. Wonder why ...
it is a 2-stroke engine with 4 zylinder, every 180° is one ignation that`s the same ignation ratio as a 4 zylinder 4 zycle engine. You compare it to a one zylinder engine, that`s not right.
it is a 2-stroke engine with 8 zylinder......
so start it up. give it some revs. show us it works. great marketing techniques. light on substance.
yeah, it's a fraud.
I spotted two serious design problems already.
You can see it working on our channel on the test bench, installed in a car and on a large model aircraft. Enjoy!
@@innengine-english don't bother... there is another guy asking for a link to the videos... which are on this very channel 🤣Great work guys, keep us posted
@@innengine-english
Now I count a 3rd major design flaw.
@@innengine-english , so what's ypur channel? where's the link? where do i send my money to?
it s been done, i had the me crazy idea year ago
Great design but it's not really a 1 stroke.
It's a new idea to the general public, but not new to all engine designers and manufacturers. The idea has been around for over 70 years. It's just not reliable enough over the timeframes established by 4strokes. It could arguably be less reliable than a wankel too.
LOVE IT!!
A 32 stroke engine. 32 Strokes per revolution by YOUR ANALOGY.
But no, it is a 2 stroke motor best I can tell, with 8 pistons, that fire off twice per revolution.
Get it right.
Perfect set up for repelling electric magnets . Replace spark plugs for magnets and you have the greatest engine that requires no gas.
looks like a 2 stroke to me, Power stroke and compression stroke.
One per 1/2 rev
it'not 1 stroke engine its 2 stroke engine
Is this engine ever going to see the light of bay or will it be squashed
this engine design has been tried several times before... it failed.
@@renaissanceman5847 where? Link pls
Self propelled engine. Green as it gets.
VCR designed by Caterpillar in the early 2000's.
There are many engines designs with VCR. The latest example would be Infiniti's. The difference is that, since their concept "adapts" the conventional engine concept to achieve variable compression ratio, the result is expensive, bulky and complex. Our design is the first one which can achieve VCR without the need of complex systems thanks having been designed from scratch with it in mind. Thanks for watching!
Compact - Yes.
Min vibration - probably yes.
One stroke - BS! Power stroke + compression stroke = two strokes.
Efficiency - power lever arm ~ 50% crankshaft
Hybrid vehicles = bad (crutch) solution
Early tests are showing close to 30% reduction the drag friction coeficient. This was expected anyway since not only we have smaller engines at lower RPM producing more power but also much of the contacting surfaces interact now by rolling as opposed to friction.
As for hybrid systems, the future is eclectic.
Thanks!
A PISTON 2 STROKE NOT 1 STROKE ENGINE.
This is a modified copy of an opposing piston engine built around 1914. It will be highly polluting as it needs to burn oil with the fuel. Quite simply an outdated 2 stroke engine having a swash plate (1917 design) instead of a crankshaft. No more no less.
not 1 stroke.
1-stroke??? It depends how you define the strokes: If you define the strokes by the movement of pistons it is a two-stroke! By this calculation a 12-cylinder 4-stroke woud be a one-third-stroke engine. :)
Besides this childish definition, if more efficient this motor would be a great deal!
By the way: As I see this design, the pistons are pushed down only by the power of combustion. Howcan you start this motor if all pitons are in up position?
They cannot all be in up position, since the intake-air won´t compress readily, to let that happen. all 4 piston-pairs can only be in the "middle" position. It works the same as if a crankshaft were there: Turn the swash-plates, and the pistons will follow/move according to the swash-plate form, suck air, compress and ignite it.
Great design, but this design dose not make much torque.
You say the motor is equal to a 2L 4 cylinder 4 stroke modern engine is efficient? How efficient? Also how much more efficient is this engine? If it is not 15% or more they automotive Boys won't look at it! It would mean gutting their engine plants & starting again.
It's hard to compare efficiency. The same % in an ok large slow diesel engine, would be impresively good in a small gasoline. We will have definitive efficiency figures by the end of 2023 as part of the homologation process.
On the other hand, you are right in your assessment of how hard it is to penetrate the automotive market, this is why we are focusing initially in other sectors where our weight reduction figures (70%) are a game changer by themselves, and any efficiency improvement is an added bonus.
Thanks for your comment!
Variable compression ratio like that, OK, 1/2 stroke ! garbage marketing ( like climate change) .... you get that with an 8-cylinder: 1 power stroke every 1/4 revolution. but I like the compactness like an hydraulic pump/motor.. yes/no?
No, it's not the same. Of course you can have the same power delivery just adding more cylinders, but then your engine is larger, heavier and more expensive. The beauty resides in having more with less. Thanks for watching!
there are similarities to the steering pump motor on the car i used to have.
Swashplate and rollers doesn’t going to last in such application :) Haven’t you heard about the free piston range extenders / APUs ? There reciprocation to rotation motion mechanism isn’t necessary at all . And what the bullshits are those “ one stroke”claims :)
You mean the same shaky, inefficient & unreliable free piston technology which has tanked aquarius engines stock after hundreds of millions invested? You seen them anywhere working in real life?

195g/kWh Que!!!!! maybe 195g/kW learn the difference between energy end effect.
Specific consumption is measured in g/kWh. In other words, how much fuel (grams) you use to produce a certain ammount of power (kW) for a certain ammount of time (hour). I hope you learned something today, thanks for watching!
If you men how much fuel it takes for 1kWh you must give us exactly the fuel energi (chemic energy not nuclear). we know how big difference it is between metanol and jet fuel.
I think that this range extender has much better potential than your. ruclips.net/video/_pBPw33ceoQ/видео.html
gr/kWh is correct. 195gr gazoline contain 2,34kWh. The engine extracts 1kWh of electricity out of the 2,34kWh of chemical energy, that´s contained in gazoline. 2,34kWh of chemical energy are spent for an 1kWh-electricity-production, or 195gr/kWh.
Not good engine. This engine for Toy.....
Too late. Still 100% fossil.
The days of "1 solution fits all" in transport and mobility are behind us and never to come back.
The future is eclectic.
So weird to hear a voice that doen's match with the person that is "supposed" to be talking... I don't think it's this guy's voce at all,
Just weird...
These are two strokes. The expand stroke is the power stroke, and the return stroke is compression. What silly marketing. A real "one" stroke would need a double-sided piston that explodes both going left and right.
You are wrong
