  • Actually u r right, if they dont know how it works they should be called idiots

  • Appreciate the demo but what an asshole

  • quick question. with regular motors you got 4cyl, v6, v8 etc. and you can sort of tell the power the car/truck is pulling out via horsepower just by knowing how many valves. How do you even determine the horsepower the rotary engine is pushing? is it all the same?

  • Witch one is the combustion chamber

  • so its better than pistons because one cycle gives 3 combustions instead one one???

  • @GodsNotReal95 nope. it does the same thing that pistons do..just uses a triangle fucked up thing instead of round pistons in a normal V block or straight motor...Has intake at one step, combustion at the next and exhaust at the last. my experience with them is they arnt anything special.

  • @jcolcord5 well i did my research and other than oiling difficulty, they are better than pistons... less moving parts, more efficient and they dont have to stop like pistons.

  • @GodsNotReal95 I don't think they are more efficient otherwise they would have moved into larger engines. Im guessing

  • seems like a simple and clear video demo, actually a pretty good job.

  • Im surprised the idiot that made this video knew how to work the internet machine :P

  • why he insulted me, i didnt do wnything :C

  • this guy simultaneously proved his point and the fact he was a dick in 1 minute 12 seconds...impressive

  • I got confused when he took the red sticker away. :s

  • How hard are rotaries to build/ maintain? I really want to get an FC RX7 this spring but I've always dealt with piston engines. I'd be looking to build a turbo 13b on a gt30r @ around 10psi. I'm not looking to make stupid amounts of power. Just a project I can enjoy.

  • @ReEducationThruLabor I wouldn't ask this guy an honest question like that. All this guy is going to do is explain something nobody cares about and then call you an idiot.

  • @jmgreetis My question wasn't aimed at any one person, just anyone who is willing to give me an answer. And it really doesn't phase me when people try to insult me on youtube because, well.... It's youtube. I'm just trying to gather information/ tips from people who have build RX7's, so that I can do it correctly and not overlook anything

  • Who is that idiot calling an idiot?

    Must be the Birkenstock company.

    ( Thought I smelled patchouli )

  • @jungledave7080 - Those are Keens. They are for desert hiking.

    WTF is patchouli?

  • @jungledave7080 Birkenstock are the best saddles every

  • a german invented this

  • @xxyy3003 only based on the rotary steam engine invented by the brits , wankel mearly turned it into an internal combustion version a bit similar to what happened to the normal internal combustion engine copied from the steam engines

  • I designed this.....

  • civic engine looks easier and better

  • @UunonMopo again. you couldnt prove to be more of a fuck tard.

  • wouldn't you conserve fuel?

  • Many thanks for posting this excellent demonstration.

    I really can't understand how anyone can dispute the facts clearly explained in this video. It does seem that some viewers are slightly confused by the fact that four strokes occur simultaneously around a rotor with three sides.

    It may be worth clarifying that compression and power strokes occur in the same third of rotation (i.e with the mid-point equivalent to TDC following compression in a piston engine).

  • so is this a "3 stroke" engine or "one-third stroke" engine?

  • i thought it was 2:6

  • READ THE FUCKING DESCRIPTION YOU STUPID CUNTS!

  • hahah "idiots.."

    

  • not everyone understands how mechanical stuff works. you dont need to get so pissed about it.

  • I like how everyone is getting so butthurt over the "idiots" remark at the end. That remark was intended for morons on a rotary forum who argued to the death against the existence of the 3 to 1 relationship between the eshaft and the rotor itself.

    Read the damned description before you comment like asstards.

  • 21:7 ratio and these engines are shit

  • "people will...argue that there is some other relationship other than 3:1"

    Only if they didn't finish grade 6 math. Anyone with a functioning brain can recognize a radical centre of three intersecting circles (i.e. those who can't don't have a functioning brain).

    .

  • Idiots!!! Lol

  • were idiots? fucken tosser.

  • so this is 1 rotor? So a 4 rotor will have 4 of those lobes?

  • u mad bra?

  • @theMazdaManiac good one! LOL! that really hurt.

  • Comment removed

  • Rapidly closing in on a million views.

    Go on and continue to be mad. lol

  • That dudes a troll with a giant turd in his butt.

  • People who think that people who don't know what they know are idiots are idiots. Idiots who say idiots under their breath are passive-aggressive idiots, also known as pussies.

  • @nosajsmas - People that troll the YouTube forums passing judgement on the content of videos without reading the are notes passive-aggressive idiots, also known as pussies.

  • @theMazdaManiac Hmm I guess you're right, I should have read the description first. But come on; is the best you can do to mirror my insult verbatim? It doesn't even apply to me. I'll take the idiot, but there's nothing passive about my comment. It was just plain aggressive. If you publish a video in which you call people idiots, you should expect negative feedback, regardless of whom the insult was intended for.

  • Were you born with that knowledge?

  • HAHA! He starts out, "Okay, for you people that don't understand how this works..." INSTANTLY you can tell he's a dick. Arrogant. Shows small thinking. He can explain how something can work, but never smart enough to invent an engine like this.

  • @Fubikon - Apparently, you also can't read.

  • RIP rotary engine, there's no good way to keep you lubricated :)

  • Idiots, LOL

    

  • YEAH THATS WHY ROTARY ENGINES SUCK BALLS, DIRTY BALLS...

  • This guy is the epitomy of patience. What a great teacher. It's always best to treat the people you are teaching as if they already understand the basic principles of the subject. IDIOT !!

  • @5151stang - This video is for people that assert that they do understand the basic principles of the subject but still insist their misunderstanding of its function. This is NOT an educational video for people that are unfamiliar with the function of the Rotary motor.

    Try reading the video notes next time before you start shooting-off your mouth. Er, fingers.

  • so umm why is he just pointing out the combustion cycle? what point is he trying to make? its still has 4 cycles of events.

  • @simrash20001

    He's only pointing out the combustion cycle to make it easier to follow (along with the red tape). 1 rotation of the rotor is converted into 3 rotations of the Eshaft. So at 3000 rpm (of the rotor) the Eshaft will be hitting 9000 rpm. maybe he's trying to point out the mechanical advantage?

  • @NigelEliki no it's for 1 rotor rotation there is 1/3 eshaft rotation .. so at 3000rpm the eshaft is going 1000rpm

  • @r3dw0lf88

    No. watch 0:11-0:24. Listen to what he says. 1 Eshaft rotation = 1/3 rotation of the rotor.

  • @NigelEliki OMG i'm so sorry you are totally right.. so yeah 3000 rotor rpm means 9000 eshaft rpm

  • he's right he proved it, either post vids explaining ur dumb shit explanations OR SHUT THE FUCK UP THANK YOU COME AGAIN.

  • Yep, he said idiots :-D You are an idiot ! do you know, that a bulgarian spen over 30 years to upgrade the Wankel's engine, stupido

  • did he say idiots at the end?

  • @dylanotoshiro may be "that's it"?

  • @dylanotoshiro

    I thought he said wankels

  • @dylanotoshiro why yes he did.

  • Asshole assumes we all know all about rotary engines 

  • Idiots indeed for using these crappy engines whats that you need another rebuild?

  • How much HP does say, each rotary chamber ad?

    I know a little about them, there's a few guys who come to the tracks and talk and I've been to their houses and seen their engines opened up. But I still don't understand if you can keep tacking on rotary chambers, why stop? Who needs a turbo then?

    And why are they so bad on emissions?

  • @psychoninja911 theyre bad on emissions because the next "chamber" that the rotor causes is right into exhaust. at high RPMs it seems like unburnt gasses are being pushed out a little too soon, hence bad emissions.

    and a turbo still forces more air into every rotary chamber, so you can put more fuel in. you could add a couple more chambers, but then you would have a lot more weight, and speed is more about HP:weight ratio than anything.

  • @darkrider789 I know, I just figured each rotary chamber would outweigh it's... weight in power. Would cause extreme torque I'd think.

    But at lower rpsm, is the emissions good?

  • @psychoninja911 yeah it seems like it but theres actually a lot of weight when u add onto a block. conisder V-type engines, it took a long time to develop a working V8... all that extra metal needs to be cooled, lubed, etc. the torque gain would be good, youre right.

    i honestly couldnt tell you about emissions at low RPM, seems like youre right, they would decrease but without hard data i cant tell ya lol

  • @darkrider789 Oh... Seems like they're great motors. I know how they work, just don't know why we don't use them more often.

  • @psychoninja911 well, they get crappy gas mileage... mid-20's on an ideal engine. They like to live at High RPM (the rx8 makes peak power at 9K... you use a lot of gas up there). They also tend to have seal problems as the miles climb, and they burn oil by design. A wankel rotary is like a performance V8... made for balls to the wall power, fuck your fuel economy standards. i have been near a 26B rotary when its runnning... sounds like a big-cam american V8 but it revs like a crotch rocket.

  • lol. Very well presented! :) I am loving Rotary engines!

    

  • i counted 4 combustions

  • @bouffslave Even with the tape? It shows clearly how for every one rotation of the shaft, there is one combustion event per rotor.

  • @TEDDERAMA 3 combustions from the engine. 1 combustion from the presenter at the end. 4 combustions :)

  • @bouffslave You are mistaken.

    

  • @bouffslave you fail to take into account he said one combustion per rotation. As he starts out he has not yet rotated the shaft yet therefore you cannot count the starting position as a combustion in his example. That combustion belongs to the previous unmentioned rotation of the E shaft.

  • @bouffslave I don't know if serious... or just plain stupid.

  • LMFAO!

  • thats a nice wankel you got there!

  • what a tool

  • Comment removed

  • Thank You Dick!!

  • whaaaaaat? please explain again.....*troll face*

  • @sasukeuchihayou - Great to see that after one year, you still expect others to change things just to defend your frail sensibilities.

  • Comment removed

  • press 9 while watching the vid if you want to hear he saying "idiots"

  • good vid.is this engine more economical than than plston engine. and why has this engine not caught on. and has this engine any faults.

  • @Liamautomechanic (im no expert) a rotary engine is NOT more economic than a piston if you talk about fuel consumption. They are known for sucking down both gas & oil, and have bad emission ratings. Which is exactly why it hasnt caught on in general, and only been really used by Mazda for SPORT cars. Other brands like Toyota has tryed as well. But it seems to be to much work for civilian cars. But, they can be brilliant for race performance. And durability if setup right.

  • @Liamautomechanic and about faults. From what I know, a rotary's nemesis'. Are 1. Apex seals / compression.. And 2'nd. The person handling it/fixing it. Other than that its pretty reliable, given that it barely has any moving parts. Less moving parts = less wear ofcourse. But what gets worn, gets worn out "fast". Therefor the rotary has always been more of a hobby/sport engine. I hope this answers ur Q's :) If not, go google or wiki hehe. :D

  • would have been better to go threw the complete "OTTO CYCLE"!!!!

  • im looking to buying an rx8 04 but are they expensive to fix if anything goes wrong in the future???

  • @Alex35J im no expert, never owned a rotary engine, but my mantra is "Get a rotary or die trying" so, im trying to learn as much as possible untill I can get one. :P And from what I've read. Then all rotary's can be .. "refurbished"? ( in lack of better terms.) for 1000-2000$. Depending on what generation it is, and if turbo or not. :) (Needed after 60k-150k miles that is. Again depending on what rotary it is. :) ) Please correct me if im wrong people!

  • @skvakagud idk if ur wrong or not but that was funny "get a rotary or die trying" LMAO LOL nd HAHAHAHAHA

  • actually what u where pointing at was ignition.. I belive

  • @kaniel16

    :/

    No shit. Know what combustion means?

  • @zanuha smh bitch please ..obviously you dont know what it means.. look up the definition of ignition and combustion then slap yourself in the face

  • @kaniel16

    I know what they mean. Combustion comes from ignition, so quite logically when he says there is combustion, there must have been ignition.

  • @zanuha this is so pointless.. like you said, for there to be combustion, there must first be ignition. What i originally said what that he was pointing at the point of ignition, not the point of combusiton

  • @kaniel16

    Let's just agree to disagree, okay?

  • @kaniel16 its called the power stroke if you want to get technical. and i dont see why you need to argue whether its called ignition or combustion. in a engine its the same thing, just different car companies try to sell it differently

  • I love building engines...would love to build one of these one day

  • yes, but in racing, where engines need to be rebuild all the time anyway, the wankel is far superior in many ways. espeially the power to weight ratio, and characteristics.

  • 240p, we meet again...

  • Wenkels don't have the torque of piston engines but have better efficiency in high revs. what I don't understand is why there are so very little Wenkels around in racing when they are obviously better in terms of power-to-weight ratio? Is it political because most car producers use piston engines?

  • @AccordGTR probably because the auto makers do not want people to know about better designs of engines. they spend billions of dollars in R&D to make four cycle piston engines more efficient, and that in turn guarantees their jobs, and income. if you are up for looking at a bunch of long vids, search "rotary vee engine." it will blow your fucking mind, and make you wonder why people still develop piston engines, and why nobody kept improving on the rotary vee design. WATCH THE VIDS!

  • @ismokewead420 Though rotarys are more efficient they aren't as reliable. They need a complete overhaul roughly every 50-70k miles due to the apex seals wearing extremely fast. Today's models are far better than they were even 10 years ago but they still need more maintenance that the average piston engine.

  • may be if you explaind the gearing factor

  • thanks for shairing i have learned somethink new today, but you dont have to be a doushbag about it......

  • ",,,idiots"

  • so its a 3 stroke?

  • @liftedJ33P

    No, it is 4 stroke. 3x4 cycle per 1 rotor revolution.

  • @corres78

    4 strokes, Intake, Compression, Combustion and Exhaust.

    In this engine those are not governed the same way they are in a normal engine (by time)... but by location in the engine.

    There are 3 faces to the rotor, and each of these three faces is constantly running through those 4 areas.

    As demonstrated in this video, it takes 3 full revolutions of the shaft for any one of these 3 combustion cycles to complete.

    So, in 3 rotations, you get 3 combustion cycles of 4 strokes each.

  • @silentthunderstorm

    I wrote the same: "3x4 Cycle per one rotorrevolution" means 4 complete cycle per 1/3 rev of the Rotor (= 1 rev of the eccentricshaft) :-)

    I know the Wankel engine. I have an RX-8 and i bought a used HP Renesis short block and i took it apart.

  • yes u idiot

  • DID HE SAY IDIOTS ON THE END>:O

  • Comment removed

  • @hidde50 he did. but theres people that think they are "know it alls" that needed some correction.

  • @bradmann85 haha yeah xD

  • So it a 1 stoke engine lol

  • This is a good explanation. thanks

  • so its baisically like a 3 cylinder

    

  • @shaybutta11208 Six cylinder because there are two sides to the engine that does the same thing at intervale.

  • Oh no! Thank you so much! My life is now complete! I now know how a rotary engine works and you only one of like a million sources to find out how it works! Your self importance sucks dude...or idiot should I say.

  • LOL! Imvented by Wankel and demonstrated by Wanker! -__-

  • @shield400 in america we call british people douche bags its an actual thing too

  • Comment removed

  • @Cattachmore22 Well that's big coming from a brit lol considering our tiny ass army kicked your giant old experianced armys ass and our teeth looked better in the proscess.you call us wankers because we have something worth wanking .called us a douche that would be accurate considering we have to clean up after ur nasty ass pussies all the time.

  • @thebmr321 enjoy your teeth while ur government is screwing you over. And funny how you mention war, given that the US havent won a single war without the aid from foreign countrys.. Either way, to both of u.. What does any of this have to do with how a rotary works? Not to mention, you might wanna get some real arguements, if u feel so strongly about something that u have to write it in inappropiate places.

  • @supernegro thanks.. Made a lot of sense... Now i know why it's limited to the race tracks and to some enthusiast... Hehehe the most i do with my car is check the fluids and follow the maintenance sched (if i have the time). Still it's a great engine, i'll wait a few more years.. Someone might just re-design this engine for everyday driving

  • This would be easier to demonstrate just by counting the number of teeth on the fixed gear and the internal gear on the rotor, should be a 3:1 ratio.

  • What a jackass.

  • I get it i just don't understand the argument. Looks straight forward.

  • It makes perfect sence but why do you have to say IDIOTS. I don't know shit about these power plant's and i guess that makes me ignorent but i'm not an idiot. I haven't takin the time to read the comments and i'm sure there are some pissed off people but what's so hard to believe about the 3:1 principle? Your description looks dead on to me. Is there some argument with this concept that you have to be so abrasive? I'm not a hater i'm just trying to understand how these incredible engines work.

  • @hpjunky70 - If you read the notes for the video itself, you'll understand the comment.

  • Hey, what are people who hate rotarys? 1:04

  • the revs that we see on the tachometer, what element are they based on, the rotor or the actual shaft?

  • @anasamla 1 REVOLUTION IS 1 COMPLETE ROTATIONOF A FIXED AXIS...SO MUST BE THE SHAFT....SAME AS YOU CANNOT COUNT EACH PISTON KICKING

  • @anasamla the actual shaft thats why the can do 9k rpm like its nothing the rotor itself is only spinning at 3k rpm if it went by the rpm of the rotor you all of a sudden have a low hp torque monster lol because torque is always higher then hp untill 5252 rpm no matter what the motor

  • HEY SPROCK DID YOU CALL US IDIOTS

  • Did he say "idiots" at 1:04? lmao

  • I think this is pretty cool!

  • Excellent video, now show me how to put 4 of them together so i can put it in a 1800lb car and fly around like a mad man.!

  • I think its great for boats and toys...not for cars

  • listen to 1:04 over and over, is he saying "idiots" ?

  • @RobbieHooker aye :D

  • @RobbieHooker haha yeh i think he is

  • bhahaha funny part at the end idiots lmao

  • Simply put, its 3 pistons in one.

  • Where is the WHO CARES button??

  • @Jonhobbs64 - Did you check your rectum? I think a few people might have stored some surplus stuff up there.

  • Seems a nice idea... How do you handle friction? Heat? And metal wear? You have one piece of metal rotating... Contact between the wall is minimal.. So, how do you cool that part? New metal alloy? What happens when one side gets eroded? Will the engine still works?

  • @icequake0110

    i own an rx8.. this is what i understood (might be wrong) from a technician at mazda.

    friction and heat- oil (thick nonsynthetic oil). the engine dumps oil into the engine lubricating the the rotor housing and the apex seals

    since that is the only way it can be lubricated, the rotary engine burns oil.

  • @icequake0110

    and erosion not sure. if its the apex seals at the corners of the rotors then yes thats a problem. but for people who know how to take care of their engines, i think rotarys are supposed to be redlined once a day or week to burn away any sludge or carbon build up stuck on the seals. doing this improves seal life, ultimately engine life.

    these are great engines. they feel like turbo i4s rev like bike engines. they arent for everyone, but those who like it, dont mind maintaining it

  • so how do they calculate volume on this? is it available volume at any time or the total volume of the oval?

  • @ogpauly that would require advanced knowledge and use of high school geometry :|

  • @kiithsjet2 You know, it is not any sort of even shape.. You could estimate, but calculating would not be so easy. It is no simple shape on the rotor or the block

  • @sheepborg except it is

  • @dirrby55 actually it was a german guy who tried to make Electric generators more efficient. read a book fucker.

  • @johnnycodekiller What's a book fucker? Gross...

  • @dirrby55 lol

  • Absolutely a wonderful video. Very educational. I thought I knew how they worked but I have to join the ranks of the Idiots !!!!! Oh well, sometimes ya just gotta be what you are.

    I have a question:

    Why are these engines not efficient as far as MPG?

    The rotary concept seems brilliant, why has the piston engine been the only choice for high MPG?

    Can a rotary engine get 150,000 miles without a rebuild?

    I trust this young man that posted this video has the ability to answer these questions.

  • @nibortheyak If you seafoam your rotary every 10k or so, it will last a life time.

  • заебись , чётко

  • @dirrby55 Everyone who thumbs up'd your comment are morons. Mazda has been using this engine for decades on their Rx models. It was designed in the 20s by Felix Wankel, A german. It was invented in 1957.

  • Reuleaux's triangle Rules!

  • @dionysos46

    correct! :-)

  • Felix Wankel-

    "This design is outstanding, but i just cant seem to make it work efficiently...

    Cool Japanese Guy-

    "Hahahaha.... Myyyy Turn! We'll put this in a Le Mans car, we'll call it 787B.
