  • People that criticize something just for their own perverse pleasure are just an insignificant fact of society. They are to society what waste product is to the human body. Just try to not let any stick to you! :) and ignore the rest.

  • @jcisbell very well said.

  • Nice machining...

  • watch?v=jErlH8odWcw

  • Peak Oil ha ha ha

  • What kind of efficeincy does this engine have? And whats the rev range?

  • This has to be the best Engine i have seen so far with limited Friction.....

  • Very nice work! The World needs more people like you! Keep up the good work! Well done!

  • They sound funny!

  • Great work! Keep it up!

  • Seems like the inventor started with a wankle, then removed the triangles, keeping the eccentric shaft.

  • @den2003 lol you make it sound like Wankel invented the eccentric shaft. The eccentric shaft was probably invented shortly after someone decided they needed to combine a wheel and leverage. Assuming leverage was discovered before the wheel (since it is a more basic concept) I can conclude that the eccentric shaft was invented shortly,in the grander scheme, after the wheel. The Wankel rotary engine began life as simply a rotary pump. It was then modified to pump air and fuel instead of water.

  • Nice

  • Freaking awesome! I love human potential!

  • The previous comment was not meant to detract from the accomplishments involved with the design and ultimate function of this engine. This type of engine has been designed for years with varying degrees of success (mostly the lack there of). I commend you on your ability to implement modern materials and manufacturing processes to make it functional. just an Idea: ceramic coating the rotor circumference, and exposure porting for maximum exposure beyond desired phase initiation.

  • attn: TheCummuted - it's not advised to run any type of fuel other than 1.Hydrocarbon 2. Methanol or 3. Ethanol based fuels because the excess water production involved would rapidly deteriorate the carbon based internals. The wear issue is the main contributing factor to these engines not being used in the consumer market. The lifespan of the internal sealing/mating surfaces does not permit extended operating times, thereby causing decreased compression, phase isolation, and many others.

  • Amazing job man,well done.what about a ledge on the rotor to act as a piston top and catch more combustion force?

  • If you ran this on ammonia there would be only water vapor as a byproduct. It may need high compression to get the ammonia to ignite. 

  • @TheCommuted that may be true but there is still no2 or NO as a byproduct but i think someone shold make a catalist that can breakdown the other byproducts and recyle them into a tank of water to create a liquid exaust where it can be treated: ie for normal petrol cars get me

  • @fatqwert200 Weight becomes an extreme issue when you're trying to lug gallons of water around.

  • I have one question if you use springs wouldn't that get something live valve float at high rpms?

  • i literally lol'd at 0:17

  • Great idea and really nice fabrication! I have always thought that this, or something similar, could be done. It's nuts to have pistons changing directions when you can have something like THIS- Awesome!

  • amazing

    great job man i have been designing something like this for ages but i havent actually started work on it yet

    so yeah im really impressed

  • i amazed that the one who insulting this beautiful invention is the one who have the most positive rates !!

    strange world !!!!

  • Very nice, but it makes such a funny sound, wobawobawobawobawobaw XD

  • Please ignore the doofuses who make snide comments here. You might be onto something big.

    Have you considered using a rotor that's not round? This would reduce the acceleration rates of that sliding valve (similar to what high performance camshaft makers do, to reduce acceleration damage). In addition, the housing might also be non-round just after the sliding valve, to make a 'squish' area to improve combustion.

    Don't give up, and please repost your progress.

    Jeff

  • I wonder how its going to hold up, it looks like almost the entire engine is a bearing surface.

  • Do you know the efficiency or friction losses, using compressed air. It looks really good.

    Peter

    

  • WABWABWABWABWABWAB BURP!!!!!!!!!1

  • Really nice work! You obviously have a lot of thought time and money in this project! Have you considered adding a faster burning fuel like hho gas to get cleaner faster burn?

  • I find especially the throttling system to be very interesting. And very nice to see in operation as well.

  • very nice. and it makes me wonder why we don't put piston-style air compressors on traditional engines. i wish you luck in the future.

  • Sounds like my '71 Honda CL70 (single piston/70cc) with the exhaust off.

  • 0:18 made me lahghf :]

  • it wont work at high rpms becaue you would need a stronger spring so the real problem would be spring constant vs rpm and of course use calc to optimize but good idea needs a large improvement maybe for generators in poor countries you sould put use to that cheep motors :)

  • i like your model engine looks good

  • Fascinating concept. Has there been any progress recently?

  • that was fantastic

    good luck

  • Oh good, another engine with very poor effiency because it relies on indirect transfer of the energy produce during combustion.

  • @Polybun Indirect? Like pressure pushing down on piston?

  • @th3dig1tal0n3 exactly. Reciprocating engines have their problems, but they do have the advantage of being a positive displacement pump. All of these rotary designs rely on surface reactions of the pressure and high velocity flow rates to work. Now it's great for power density, but very poor for efficiency. Wankel type rotaries suffer for this reason.

  • @Polybun I believe engines with external combustion chambers are the road to efficiency. This design might be low on torque, but is prime candidate for external combustion chamber rotary hybrid. I believe simplicity and high power density will be the prime mover towards enhancing this design.

  • but the valve its going to sufer to much wear dont you think?

  • Very interesting. Surely the Mazda rotary issue of economy still hampers this project like anything with a port transfer system ie 2 stroke bikes? Great to see someone design and build something new. How is the wear for the graphite vane seals? Love the ability to switch them as needed too. And to all the negative comments- put up or shut up losers. Whadda you built??!!

  • To all you knockers! What have you ever developed ?? Bugger all I'll bet !  Big with the mouth aint you? If you haven't got anything good to say about some one trying to improve tings keep your Fucking big mouths shut! Ass holes!!!

  • Who ever is bitching about the sound is stupid as hell it is small version of what it would be if in an actual car.

  • if cars start sounding like this im just going to kill myself

  • @sqweem

    Go on do it !!

  • nice work dude thumbs up.. its just has an unfortunate simularity to a queef...sorry had to bring that up have you cosidered a ethenol fuel you get extra funding from the alternative fuel sector.................. keep up the good ideas the world will be better for it

  • thaks for sharing this information is been of great help

  • lovely engineering mate , i salute you .

  • this looks/ acts like the engine angelo di pietro designs (engineair pty ltd). except that his has multiple uhm.. fingers. or vanes. whatchamacallit. im not an engineer. but yeah.

  • How cool would it be to wind the core with wire and make this a hybrid gas/electric motor with the same driveshaft!

  • @maxneu No

  • Great concept. Are you planning to develop this working prototype further?

  • what kind of equipment would you need to shape thoes metal parts? also what kind of metal would that be made out of?

  • good idea

  • somebody spent alot of time machining that

  • I love the simplicity of the design but worry how its lopsidedness will perform with extremely high rpms. Have you considered using steam power instead? Steam offers high torque with low rpm, as well as far more flexibilty in terms of which fuel is used. Cheers.

  • How's the vibration level at full throttle?

  • Great Work!

    But not to copyright it might be not the best way because anyone can just copyright it.

    Maybe you can put it under the GPL (general public licence) so everyone who made further developments has to publish his changes.

    The GPL is usually for Software like linux but maybe its adaptable. 

  • @Fenrisulfir - I think some people have already adapted the GPL to open source hardware, maybe he should see what the BeagleBoard or Arduino guys did.

  • that is sweet man! someone could make some major money off those. ive always been a fan of rotarys. therre pretty legit

  • Is this that MYT engine?

  • whoever copyrights this will make some big time bank one day lol

  • So this engine would run on a mixture to provide minimal lubrication?

  • it not exactly the same as a rotory because it runs in a cylindrical bore,a rotor has aoffset rounded triangle shaped rotor and automatically seals combusts then pushes burnt gas through the exhaust port.i think i have a better idea if i can find the right fluid/gas that doesnt include burning.

  • isnt this basically the same as a wankel rotary engine?

  • Ok,, Soo This is No Longer The Triangle Rotor,, But Circle in A Cicular Engine,,, HOW EFFICIENT IS IT< In Contrast To The Triangular Rotor Engine?, :?

  • this is like a rotary compressor

  • great design, congratulations

  • sounds like your mom on a lonely night

  • cooling?

  • awesome!!!

  • I want a car that sounds like that.

  • plututututututoot!

  • Hit n miss engines did the same thing when they did not need to fire. A true hit n miss held the exhaust valve open and only closed it when it needed to fire, however under load the engine would fire more consistently. As a result the engines were light on fuel consumption. (2:04 to 2:18) I like the idea and commend you for trying and succeeding.

  • That sounds REAL intimidating. They must've used sound dubbing or something, cuz the RX-7 Vin Diesel drove did not sound like that rotary queef going on there. HAHA!!! xD

  • Is that a shaft from a normal rotary engine.

  • Any ICE is going to suffer from the same thermal in eff. Find a way to use the energy from the hot exhaust gasses. That is where most of the eff looses are taking place.

  • Beautiful ! Good job !

  • hehe its a block :D

  • sounds funny lol

  • Nice job.

  • Too noisy?...too dirty?...and the valve gear seems to have to much friction?..longevity???

  • the idea is good, but the valve that divides the combustion and intake area would not be able to take the strain of combustion,

    it would definately run smoother than a standard rotary engine.

    if its possible to make a different partion that is stronger yet with little friction then this engine would work briliantly :D

    wish i had the tools to make my own engine :(

  • @waterfordjim

    Yeah, give it a go

  • sounds like a 2 stroke lol

  • Maybe because it ignites every stroke?

  • i love the way you expose the combustion using transparent materials ^^

    thus i dont really get how that 'valve' works :/

    alos i wanna know 'how do you manage to develop those parts?' are you employeed in a research facility or doing it all yourself?

  • Tight display rotation man

  • How much hydrogen does it require to run a small version?

  • keep up nthe great work,

    google STEORN and check there magnetic moter...

    we need yr help working on fuelless engines..

    research and see what can u contribute!

  • cool cool

    keep posting

  • excellent design prototype.very easy to balance and seal.i think it might need forced induction to get air to go in or the direct injection of oxygen and fuel.the only issue it might have is thermal efficiency if the mixture is not compressed this might create more heat than momentum but this will definitely work one day

  • the prob with rotary is no torque so you need rpm and there goes your mpg. its a dead horse. kick ass machining and engeneering though.

  • I dont know why you got so many thumbs down, you're spot on correct.

  • thats pretty neat lil motor

  • @xIIIIII1IIIIIIx Between what I heard and what you wrote I almost fell out of my chair and on the floor.

  • @xIIIIII1IIIIIIx yeah at 0.18

  • @xIIIIII1IIIIIIx

    you are a moron :)

  • The compression ratio is very important.

    This engine has a small compression ratio.

    Wankel engine, compression is 13 / 1.

  • not triangle but do the job no˝piston rings ˝

  • so is that really what it sounds like?

    also what is the max RPM it can hit?

  • Dear oldschool,

    This is what it sounds like in this crude

    version. RotaryICEman got it this far. He

    has put other versions aside for now.

    I can guarantee that in it's most perfect

    final version, it will produce about 1/3

    faster RPM that a two cylinder four stroke.

    It will also have a muffler.

  • thats cool thanks man

  • I hate to pour cold water on your ideas but the technology to replace the internal combustion engine has already been implimented in the form of hybrid cars it is only a matter of time before cars like the "lightning GT"(a full electric that can charge in the time it takes to sip a cup of coffie, and costs peneys operate) completely take over the market!!!

  • I don't know where you're getting your information, but it doesn't correspond well with the reality of EV technology. Here's an example for you, Raser Technology touted a 100 MPG Hummer. However, it takes 100kWh of power to recharge this (3X that it takes to run your house). So when the equivalent cost of this energy is considered, the Hummer gets 8.7 MPG. BTW, their hybrid ICE provides only half the power that they need.

  • Well madback. You like cold water, as you

    have no hot ideas. A hybrid is 1/2 ICE so

    an improvement to it improves hybrids.

    There is no such viable technology , such as you speak, and most of the electricity

    comes from coal and nukes, costs more

    than pennies, can't deliver that much that

    quick and no electric power storage device could absorb it that fast, and

    what about cost of this GT. I suppose Frankenstien told you this dribble.

  • sorry fellows but a guy called Ralph Sarich tried making these in the 70's his company is still going it's called Orbital engine co.

  • ever feel like youve been here before, and right as you figure it out you wake up a baby, it take another 40 years to start again?I do

  • I think I'm gonna stick with my mechanically fuel injected engine that has grandfather rights.

  • It will suprise you how simple the problems that this version points out,

    can be overcome. It can be sealed

    with two small and easy improvements.

    This design is not a piston, it is a true

    eccentric rotary engine. It lacks the rolling

    and sliding action that an advanced version will use, that will put it far ahead of anything out there.

  • This is public domain now and can't be patented. It can be improved.

    The Bourke is a great concept, This may

    prove better.

    Beings this is a two stage two lung machine, they balance when set 180 degrees apart.

  • Russel Bourke's engine is also public domain technology, and while interesting, their are many better ICEs out there.

  • What are the better ICEs out there? You have no clue. You have no facts. You have

    a warped imagination, is all. Admit you

    read too many comic books.

  • Oh please. If you'd like to remove the electrodes from your rod for a moment, you can see a much better ICE at mce-5 . com

    This is only ONE of the top 50+ exciting ICE technologies in current development. You may also want to google Scuderi to see another that's been in development for many years. It has some interesting tech, but will never be practical in my opinion.

  • Wow it sounds like a chopper! I would patented if I were you

  • Boop Boop Boop lol fummy sound

  • you need two that counter rotate so the vibrations aren't so bad

  • does it run on air?

  • it would appear to suffer from the same problem as all other rotary type internal combustion engines and that would be the seal. when viewed in two dimensions the seal doesn't appear to be all that great and when viewed in three dimensions the seal is much worse, the more you try to fix the seal the more friction becomes a factor which is exactly why rotary engines never got put into common use but for those of you who like them Norton is making a rotary engine motorcycle that might intrigue you

  • the engine is gonna vibrate my ass through the entire seat off my car

  • @runescapeownsnubs

    Powerless?

    Lol your life and runescape are pointless

  • Yes.. powerless. And you don't make any sence. Try insulting me when you pass second grade.

  • @runescapeownsnubs so your saying Rx-7 is powerless? Hey buddy i am done with college already and ive had 3 cars and a gsxr, so don't tell me what I do and don't know.. your probally atleast 10 years old who plays runescape still.

    and yes I played runescape before (In second grade)

  • I have an RX-7 with a 13b and it has so much power, i never said an rx7 is powerless, i'm saying this model is powerless it does like 1rpm and is pretty much useless for anything. it might be able to blow some bubbles, and i'm not meaning to offend anyone

  • its a bloody model idiot, the real thing would be bigger faster and better.

  • how many times have you rebuilt your gixxer?

  • @robby844

    Never... loser...

  • LMAO then you dont ride her.i feel bad for you.you claim youve done all this BS and have all this money.LMAO

  • @runescapeownsnubs maybe you should go back to second grade... and learn how to spell sense...

  • It was called a wenkel rotary engine I think...it's been 15 yrs since high school lmao

  • this works on the same design but the true wankel has a three point rotor as opposed to this engines circular rotor

  • Actually, the Wenkel is massively more complicated, as it also incorporated some aspects of a reciprocating mechanism, as opposed to this design which is purely a rotating piston.

  • look up the bourke engine.

  • When I was in high school my power tech teacher had a model of a rotary engine. That was the coolest thing I ever seen! Even how they worked. Didn't Mazda put rotary engines in their cars?

  • yes. the most famous being the mazda RX-7 and the RX-8

    (4)the replacement for the cam-shaft system in the engines So,any body who wishes to by one or more of these inventions,for the aim of producing it or them for the welfwre oof all huminity,not only for profit, individually or companies,from any spot of this planet,,let him...

  • ---1---

    Every body hear me,,,

    I am Amir Toma,a very simple mechanic,at the present time I live in Canada-Ontario-windsor. I worked on the idea of the rotary engine since 1978,and (that was a great mistake then in Iraq)I presented the -incomplete- papers of of the design to the Information Office of the Republican Palace of Saddam Hussain in 1984 according to an advertisement on the T.V.of Baghdad encouraging inventors and designers to present their ideas and innovations,with promises .....

  • Add a vapor carburetor and you have it....

  • stillbirth

  • Sounds like George Jetson's space car! *laughter*

  • Good luck maintaining those seals! Orrr! Orrr! Orrr! (seal sounds).

  • If you can keep the combustion chamber sealed (as well as fixing the bearing problem) this could be big.

    But you still have to fix the fact that it sounds a bubble machine running underwater.

  • can it be moved by air?

    how strong is it?

    can i use it as a car engine?

  • I don't understand why you call it a vane,

    when as a compressor it is known as a stationary blade compressor. A vane compressor is yet another type, and very distinguishable.

  • Fantastic. You really have your stuff together.

  • Very,very nice.Please check out my rotary engine concept. Thanks.

  • Replace the vane with a bearing so that it rolls instead of slides.

    Your vane wear problem is gone. :D

  • Exactly, I came to the same conclusion

    about ten years ago. My roller-blade

    replacement is a ball point pen, using

    a roller instead of a ball.

  • WONDERFUL WORK !!!

  • Looks like it would last much longer than a Wankel. Not as many sharp edges to wear off.

    I'd love to see this in application. A Go-kart maybe.

  • The rotary for mr bubbles!!

  • Sounds like a Bubble minigun! xD aaaAAAAHhhhhahahahahahahhaa

  • If you take a conventional engine and put to run by it's axle (only to demonstrate it's work) , it will sound like it .

  • Sounds cool! ^^ (And fun)

  • it sounds funy AEHAUEHAUEHAEHAUEhAEUhEUhUAhAU­hAEUhAEhEuhEuAEuhAEUhAUEhaEuhu

  • Lol, the timing belt is $40, spending 14 hours to tear appart half the car and put it back together is another $800, that is why people don't replace them. I doubt this will be more efficient than the modern rotary design for whole slew of reasons since it is almost the same design except it has recipricating parts, doesn't use combustion pressure to maintain a seal and has very long sealing paths. I doubt it will maintain power at an efficient rpm for very long. Stated for constructive purposes

  • Simply delightful. Congratulations! :)

  • Is this possible to do with some rotary fridge compressors attached together ?

    (or something).

  • bravo man this thing is amazing wish i had enough patience to build stuff keep up the good work

  • hehehe it makes funny noise hahaha hehehehe hlsdofsldfl

  • Most new ideas go absolutely nowhere, and this one may very well join those ranks. But if we were to let that deter us, then innovation would surely die. Also, this design draws allot from prior art, and it's possible that some future work can in turn benefit from some of these ideas.

  • Nice ,we need to get away from rod and piston Now!

  • Thank you.

    Any idea of specific power, specific fuel consumption? How about throttle response? The sound is certainly less aggravating than piston engines :)

  • Both 2-strokes, and Wankels have higher specific power. This design is all about efficiency, and I expect specific fuel consumption to be second to none once the seals are perfected. Throttle response is excellend due to the unique vane modulation scheme which effectively eliminates throttling. Sound is one measure of engine efficiency. An engine that's expelling hot, loud, high-pressure gasses, is throwing away energy out the exhaust pipe. These models operate without mufflers.

  • Are you talking polluting efficiency or non polluting/ hehe, piston engines can get up to 3 times the efficiency they do now, if emmissions weren't an issue. The other issue of having a lower specific power is larger engine volume/unit power, not displacement, just package size. Non throttling is good. Seals: a minor sounding issue can become quite the headache. TOTALLY agree on the sound = wasted energy. Thanks for the reply, kudos on the nopatent. Parallels linux :)

  • Avesome! Thanx for all creative people for supporting evolution of technology. Shame on those people and companys who make it difficoult for them to release their invention to public. Dont give up, youre not alone.

  • Thanks.

  • i compend the enventor of this, and his healthy outlook to being flexible...

  • will this engine run on hydrogen fuel? Make sure you have the bubbler and backfire arrestor ready.
