Wankel Engine

[ChrisLuxembourg]

2:03 ...it looks like an modern electric vehicle!

If "Felix" could see this, he would pimp out the NSU Ro80 with that engine!

[VampirateYuki]

@ChrisLuxembourg Believe it or not, they had electric cars before they had cars that ran on gas. However they deemed gas cars were more efficient so that's why we use them today.

[ChrisLuxembourg]

@VampirateYuki Combustion engines have an efficiency of 40%. The first electric automobile to reach 100 km/h in 1899. The problem of all this EV's, they are to heavy and the range is limited with the used PB-batteries.

But today the battery technology has been changed, all system are running with regenerative braking. The only real wearing part(all 5-6Years) on EV's is the battery. The other parts are low-maintenance! I think, that are to much features for the oil-industry...

[alconaftika]

Soooo, if its not semetrical, wont it also cause vibration?

[7Jfigo]

@alconaftika The weight balance of the shafts counterweights and the other rotors spining at different timings stabilises and causes minimal vibration especially at low revs. Its quite astonishing as an engine.

[NaziGOPBallmer]

@7Jfigo

Imagine if all major automotive industries switched to that as standard, hehe, think how many jobs will disappear over night to make room for ones that make sense. In anycase, I'm still trying to determine why this engine design uses more fuel than V-engines. I suspect that it was designed more for power than speed, but I could be wrong as this type of subject isn't my forté.

[7Jfigo]

@NaziGOPBallmer The reason why these took more fuel typically was because they spun at a much higher rpm. Where a car stops at around 7,500 rpm these go to 12,000 rpm. It didn't take much more fuel though. There are still lots of cars on the road that use wankles but there more japanese sports cars like the RX7.

[NaziGOPBallmer]

@7Jfigo

So even at idling, they consume more. Interesting. I'm beginning to understand now, sort of. Maybe the fact that the rotary design is able to house in more than one cycling process in one stroke is probably the reason why the engine takes in more fuel than the V-engines. Would that be true?

[Staytheredoggy]

Haha the bug at then end made my day I love how they didn't edit that out hahahahaha

[ToricoUK]

Tiny what?

[Caqui]

@ToricoUK That's what I want to know!

[theevilmeister]

Who the hell comes up with this shit

[33ProSport]

@theevilmeister felix wankel! haha 

[illchillkyle]

I love how this guy walks!

[you2tube22]

"the connecting lod" hahaha!

[r0b0hobo]

WHAT THE FUCK WAS THAT AT THE END OF THE VIDEO?!

[omid11]

still take an inline over rotary, v, and flat any day!

[vrbas100]

Wankel je fantasticno resenje ni diesel ni benzinski motori nisu toliko mastoviti

Genius Felix Wankel ,respect deserves my ,ENGINE No 1

ciao from SERBIA

[Superchickenman159]

oh my garsh, tiny is up next. :O

[robsnizzle7]

best motor ever produced, the amount of power this motor can produce is siiiick!!!!

[crazy1kid2]

could you have like a 4 cyclinder wankel engine?

[robsnizzle7]

@crazy1kid2 can't have a cylinder Wankel when it doesn't have cylinders bro, U can make a 4 rotor motor but takes machining to do it.

[crazy1kid2]

@robsnizzle7 yea i didnt mean cyclinder, i just didnt kno how else to describe it, so why dont ppl use 6 rotor motors then, isnt the mazda only 2?

[robsnizzle7]

@crazy1kid2 6 rotor motors are possible, but due to having to modify 2 20b motor's (3 rotor motor's), it's alot of work...... alot of machining needed....... but is possible (an boooy the power out of that motor would be INSANE!!!!!).

[NJRocks281]

tv not invented in Japan

optical fiber, invented in US

electric guitar-invented in US

cd- joint US Japan

Your list of 5 ish inventions is actually quite pathetic.

[zaco21]

@NJRocks281

The CD was invented in Japan. The Blue Ray disk was invented in Japan, the blue laser was invented in Japan. The Optical Fiber was invented by an Indian immigrant. There are a lot of Japanese Inventions. The US ad a lot of inventions created by immigrants.

[360mmspider]

i would want to buy a rx7 or rx8... not really for my main car but to store.... i think in time its probably going to be worth some money with its rare engine.....

[kriegdouch]

i like how the japs got influenced by german enginering. Mazdas make the rotary engines replica of the wankel engine, Suburus boxer engines are the replicas of german volkswagens. here in america, the car companies are influenced by the japs technology in automobiles, how some dodge/chrysler used mitshibushi enginiring. electronics have to be japenese.

[NJRocks281]

japs always copy western tech, Then they sell it back to us. Look up Japanese inventions. The list is surprisingly short.

[zaco21]

@NJRocks281

Actually the list is pretty long. Longer then the list of American Inventions. I think you are confusing them with the Chinese.

[NJRocks281]

No the American list of inventions by far the longest in the world. Look for yourself.

[zaco21]

@NJRocks281

I did, a lot of them are made by immigrants and some are improvements over previous versions that have been claimed to be invented by the Americans, like the floppy disks for example. If this is the reason that the US have such a list of inventions then you shouldn't brag with it.

[NJRocks281]

nah 90% were made by born americans

[zaco21]

@NJRocks281

Wouldn't be so sure about that. The innovative minds in the US are immigrants, it's a known fact. Anyway, Japan has better technology then the US. It's a fact.

[NJRocks281]

Ahhh name some please. Aside from Tesla. And Japan most definitely does not have better tech than the US. All they do is copy western tech and sell it back to us. America consistently gets ranked as the most innovative economy by the UN.

[zaco21]

@NJRocks281

Eugene Houdry and the guy who invented fiber optics and many others....

The Japanese have better technologies then the US. The UN is sponsored by the US so the title is irrelevant. Most of the companies with high tech products rely on immigrants to develop new products. Most of the teachers in the American Universities are also immigrants.

[NJRocks281]

I go to an American university and 95% of the teachers are American. I bet you have never step foot in the US. The US patent office holds over 8 million patents the largest in the world. 90% were from Americans. Japan just copies American technology. Everything from the lcd screen to the microprocessor. Same with cars. America invented the modern car. Everything from the auto-transmission, to electric starter, to the windshield wipers. They didn't even make the Wankel engine in this video.

[zaco21]

@NJRocks281

Well, I didn't, but my teachers did, and they told me a lot about it. Te US as a very good college system but a lot of the teachers there are from other countries. What University do you study at? Microprocessor was invented by Japanese and the LCD was perfected by them. Americans invented the modern car? I don't think so. 90% of the world's patents? Let's be serious. If the US have 10% it's quite something.

[NJRocks281]

I didn't say the US had 90% of the worlds patents you idiot.

The worlds first microprocess was the Intel 4004 (U.S. Patent #3,821,715), invented by Intel engineers Federico Faggin, Ted Hoff, and Stan Mazor. America perfected the lcd screen and we also invented the cellphone. America ranks top and the most entrepreneurial and innovative economy consistently. America leads Japan follows.

[zaco21]

@NJRocks281

You said that 90% of the world's patents were from Americans idiot, from a certain point of you can understand that it had 90% of the world's patents (because they were invented by Americans). Masatoshi Shima who also co-invented the microprocessor. The LCD screen, but the LCD TV was invented by the Japanese (Sharp Corporation), and by doing so perfected the LCD screen because the image quality offered until then wasn't acceptable for television.

[zaco21]

@NJRocks281 I told you that a lot of the inventors of American inventions were immigrants, well Federico Faggin was an Italian immigrant, let's not forget Masatoshi Shima. Do you know how many designers of American inventions developed by corporations are immigrants? Japan has better technology. The US have progressed because of Japan and other countries.

[zaco21]

@NJRocks281

The LCD and Plasma TVs were created by the Japanese.

[besman007]

@NJRocks281: dude the only reason why the u.s has stayed ahead in all its 230+- years, is because it creates instability in other reagions of the world!, look man i aint trying to start shit or talk shit, this country is great and has great citizens, but thats just the way you so called americans are, you will do ANYTHING to stay ahead..

[NJRocks281]

America creates instability...Lets See Vietnam, Korea, Grenade, Somalia, Gulf War, Afghanistan...they were all already unstable you fucking drooling sack of shit. Stop breathing my air.

[besman007]

@NJRocks281: lets also not forget that most of the real jobs (careers) in this country are occupied by foreigners..if you take al foregners out of america, and i mean ALL FOREIGNERS, this country would pretty much colapse if im not mistaking..this country is multi cultural and the most multi racial country on this planet, so there is no such thing as an american no more..

[besman007]

@NJRocks281: America forces and pressures other countries to buy its products and it also pressures other countries for the u.s to come into their country to invest..if other countries dont listen to america, chaos starts though politics from the cia!..its a known fact and i've traveled and asked and seen, and i'm not being one sided here..

[zaco21]

@NJRocks281

I think you are confusing them with the Chinese.

[VALsacount2]

@kriegdouch It's all just nigga technology anyway.

[thegraveyardboys]

I don't think he is serious about getting 15 mpg. I work with the wankle it's my job

[salzahrah]

how does this not require a intake valve?

[whatUsaybob]

It's like a 2 stroke, it has ports. Gives the engine less parts to worry about, and less parts to lose power on.

[varkow]

the piston works it self like a valve, controling timing of intake and exhaust. =) nice engine just like 2 strokes

[Rathearia]

it still intakes air, it just gets it through a port on the side of the rotor housing and the rotor does the rest

[c00smeen]

Also, the fuel INefficiency is due to the fact that the rotary engine requires high engine speeds to make serious power... driving at low RPM in the rx8 for example it guzzles more gas because it has less power to pull the body...

[whatUsaybob]

Also from it being a hybrid 2 and 4 stroke. And every revolution it has a combustion cycle :). So it's not really "INefficient", it makes about 200HP at only 1.3L. The 13B-REW, output 280HP with two turbo's.

Power to weight is high, but also has apex seal problems because, unlike piston engines, they don't hold oil and keep it there. If they could fix that then the wankel could get somewhere really quick :D.

[c00smeen]

yeah but I can get that kind of power by turbocharging a 2L, 4 or 6 cyl engine without the bad fuel efficiency and a common engine on wich spare parts are relatively cheap...so ''wanker'' loses again...but yes indeed it is ze fucking scheisse engine, 280 hp in a 1.3L ? that's amazing...

[whatUsaybob]

Ok they only get bad fuel efficiency because of lubrication. The seals get oil by the oil injected into the fuel/air mix. And the engine needs to run rich because of this reason, remove the oil injector and lean it out, problem solved. The oil pump only does the shaft and bearings.... so again if you need help looking up stuff or HAVE an actual rotary powered (Like I do) car then I can help you. Otherwise please don't reply, Plus repair of a normal engine cost more, sorry but fact.

[c00smeen]

by ''ze fucking scheisse engine'' I meant that it is a fucking good engine it's a 1.3 and puts out 280hp,we are talking lawnmower size engine,

but I wouldn't buy it ...ever...cuz I wan't to feel the vibrations in my car, not just look at the revs and shit,I want to feel the car...the wankel just spoils the whole thing...and you're wrong man...how can you say that an engine who has been buildt in a small number it's cheaper to repair that a normal engine for wich you can find parts anywhere?

[c00smeen]

The Wankels are not efficient because of the displacement...It is a 1.3 liter engine wich is extremely light and who has to pull a 1.3t car...the engine is too small for the car...to reach it's peak performance the perfect engine would be a 1.6 wankel...but the 1.6 would be offending at fuel efficiency,with the 1.3 you get about 15 mpg but in the 1.6 it would prbably be like 7-8 or worse...allthough it is impressive that a 1.3 engine is able to put out 232 hp.

[Draelren]

wow you are spitting out a lot of "facts" that are wrong. It does not get 15mpg... Average is around 20 or so, and I know some people who get 30+.

[c00smeen]

@Draelren

yeah...U KNOW SOME PEOPLE...that explains it all...

we can all go home now cuz u know all the facts...

[Draelren]

Okay? Are you really getting offended because I'm saying that you're wrong about the gas mileage?

When I got my car, I was averaging ~22 mpg, and that was with redlining it most of the time during acceleration.

[O5rx8Mazda]

I love rotary engines...

[masticina]

I understand so far that many small plane engines are the rotary type to. Showing how efficient it can be.

In cars well I like it it is smooth. Even if to get the real power out you need to rev high.

Yup I like rotary engines.

[Velktron]

In Britain, in the 1960s, Rolls Royce Motor Car Division at Crewe, Cheshire, pioneered a two-stage diesel version of the Wankel engine.

[Clap4meBitch]

It's basically a supercharged engine.

[Velktron]

Yeah, I suppose they would have employed some serious supercharging/precompression stage in order to achieve the necessary pressures/temperatures for diesel ignition.

[Clap4meBitch]

All you need is a turbo and a single sparkplug :-)

[akinadownhillace]

Do you even know how a supercharger works?

[Clap4meBitch]

No, I'm stupid.

[sunimunipuuhun33]

wanker

[koronius]

mazda rx  =)

[Basspost]

The Wankel engine, in it's various configurations, has been on the scene for a long time. If it had significant merit, it would have replaced most of the piston engines by now. It hasn't, it will not, and it eventually will find a corner of history to rust away into! You have no idea how much I wish I was wrong!!

[Clap4meBitch]

There are always niches for the Wankel. I'm working on one now :-)

[787brx8]

I have worked on the Renesis engine with Mazda and know of at least two new engines that are in the works.

The new 16X is not only bigger but should get better gas mileage than the current RX-8 engine.

The 16X will make more torque at lower RPM's though changing the geometry of the engine.

Not to mention the new rapid burn technology that Mazda will use. I already have it on my cars!

As for replacing piston engines with the rotary engine it has already happened everytime someone buys a RX.

[Mrung0wa]

I had a 74 RX4 Coupe with a 13B with a 4 speed in High School and loved it!

[bobbedie]

kub kubi kowawah 2:17

it got funier every time i played it

[yontopapa]

May be you enjoy "The Best Rotary Engine" here in YouTube.

[evil13b]

awesome god bless the wankel

[trucker11686]

Rotary FTW.

Former two time FC RX7 owner myself.

[yontopapa]

I am sure the "Motor Rotativo Yonto 3", here in YouTube, is the best Rotary Engine.

yontopapa

[rayunseitig]

Thanks for posting this, I like rotary. I made a little video on one also.

[Daddy0089]

wao incredible video... amazing! Mazda LOVE!...

[ChetCampbell72]

Drivers seat and said "now you." I got on it and he is like "FASTER! Harder!" People, I never knew how much power that little freaking car had until it was driven like that. For the next couple of weeks he drove with me and taught me what the car could do, I shit you not, I took a turn at 80mph and that thing held the road and this was stock. These cars are no joke, small, unassuming, but it is all kick ass.

[ChetCampbell72]

The Germans and Japanese working with eachother.......where did we hear of that one before!!! j/k.

[MXtreme89]

Yeah, truth be told below. I hear of apex seals going bad all the time, and if abandoned can be catastrophic.

I don't want to rip out my engine to change seals every 60,000, that's for sure.

[ChetCampbell72]

The seals were a problem back in 1979, that doesn't happen anymore.

Besides, have you ever taken a rotary engine out before? The thing is about the size of a 5 year old and weights nothing. The labor is what costs, the engine is cheap.

[MXtreme89]

Nope, I never knew how they even worked until yesterday. That was just something I frequently heard of in the car buying market. But, now I know. Thanks for the knowledge. :)

[50fordman]

@ChetCampbell72 let alone the power output of a 1.3l rotary is 286 hp to where a honda or toyota 1.3 would be about 100 hp

[lvcsslacker]

I just hope mazda never gives the Wankel up entirely... It's a brilliant idea, really.

[LoneOarman]

Only 3 major parts, but over 100 seal related parts (problems).

[rockolutheran]

heh wankel is such an unfortunate surname :P

[thejunkman]

Its too bad that design is a pain to work on. Especially when the sealing surfaces wear and you start having compression losses.

[dsm664]

most of the sealing issues are caused by carbon buildup because of old ladies and wankers not giving it a good 9000 rpm run often. but yeah, if apex seal technology were to have a leap, then these engines would be 300,000 mile engines before rebuild.

[lvcsslacker]

I know you posted this 4 months ago, but just out of curiousity, do you think Mazda's idea of larger rotors will help it's longevity and fuel consumption?

[ChetCampbell72]

Those old ladies would be me. I was screamed on by my mechanic who was like a Father figure to me, he said "this is a sports car, it WANTS to be driven hard, and not that you have to drive like a freaking maniac all the time, but if you never do, carbon is going to build up and you will ruin the performance." To make sure I got the point he got in the car and "took a ride" with me. He hit the gas to the floor and shifted hard and this shit flew out the back, black shit. He then put me in the

[memeome]

How does MYT engine compares to Wankel?

[stuviman]

he he wankel

[dtbrown1978]

To bad their gas mileage sucks and they still burn oil. Still great motors.

[Marine475]

I don't think so, compare mileage on nissan 350 z and Mazda Rx8 and you'll see that it's not that bad. Sure it's not 1.6 honda civic but it has twice the power.

[de7ilznite]

is it possible to change a piston engine to a wankel one?

[crackerworld]

de7ilznite ..no, it's different architecture, you need another engine heheh

[vitaliH]

if im not wrong , i think he means , replace a whole otto engine to wankel ! and why is that inposible? sure he need to fix alot to fit that engine but its possible :) !

[crackerworld]

vitaliH, change a whole engine to a wankel engine is possible. To modify an existant piston engine is impossible.

[ViolatorRedRR]

thanks for the video the Wankel is a great motor. if you want to see the history of motorcycles i have it on my site all 9 parts. Thanks to the history ch. lol

[Oddman1980]

I have one of the first Rx-7's built in 1979... Very very fast little car. It used about a pint of oil for 1,000 miles. If your Wankel is "belching smoke" then your metering valve is out of adjustment, or you have a broken seal somewhere. I've seen these engines still running after 200k miles, and require no more maintanence (sp?) than a typical reciprocating engine.

[mystikalecho]

my dad told me that the Blades of the rotary engine will wear off - ranging from 150,000Km to 300,000km.

once you've done this many ks, your rotory engine will increasingly show signs of Deterioration in performance as you do more.

I ask my cousin, which is a another major Drawback but wasn't mentioned in the clip, he then tells me..."you would have to change the whole engine!"

I guess that's probably the reason why cars with rotory engines depreciates in value greatly. e.g rx-8

[Oddman1980]

No... you don't... They can be rebuilt, and they don't even have blades. They are rebuilt all the time. An older Rx-7 in good condition can bring about half as much as it sold for in the first place, sometimes they sell for as much as they sold for brand new. I'd not call that *Great* depreciation. Has your dad or cousin ever owned one, themselves?

[mystikalecho]

My dad fix and sells cars..and my Cousin is Mechanically inclined for his age, supposedly. he also wants to own a shop.

[allowdestroy2012]

i like that engines but they are very expansive to buy and to mateniance

[dustziggy]

New rotary's dont use much oil guys LOL. Thay dont have oil belching out of the tailpipe like a 2 stroke. In fact the new rotary engines use less then some piston engines. Only a few lts per 10000, who cares.

[dustziggy]

And no a rotary is not a 2 stroke, the combustion chambers are allways seperate so you dont get waisted fuel and oil like 2 stroke.

[mungoesmad]

It has a total loss oil system, like 2 stroke engines. They are almost illigal in our country because of the smoke belching out of them. Make one that does'nt burn oil and you'll become the next Bill Gates.

[willberg1]

If you ever drove a rotory, it feels so odd at first. The RPMs at idle are so slow, it almost feels like its not running. But Again, its a great engine and its still one great 100,000 mile runner before giving it new seals. Cost effective compaired to a piston engine, Very much So.

[mipmipmipmipmip]

I can confirm that, had a test drive in an rx-8. I tried to start the engine a second time because I didn't notice the engine was running already. If there would only be a way to bring the fuel consumption down. I guess the main problem is that it needs a lot of revs to get power, and fuel burns away with these revs.

I'd like a second hand rx-8, but it's hard to find one that hasn't been modded into ugly-ness by extra spoilers, etc.

[higgrobot]

I had a wankel just then.

[UncleGenghis]

was it good for you and did the ground move for you?

[higgrobot]

It was fast and noisy :)

[UncleGenghis]

LMAO sounds like you are using the two stroke method!!!!!!!

[Ruupie1982]

Great video.

Wankel engines rule ;)

[fc3sghost]

LOVE THE ROTARY ENGINE! Got to thank Wankel for it man. Plus if it wasnt for the dream of 1919 i dont think we would of had this beautifull engine. LOve it.

[panoulis20]

they guys face in 0:20 looks like the thing in 2:52..lol

[peterman81]

I love my RX8, for the money the best vehicle in its class BAR NONE - Who cares about gas mileage - it's a BLAST to drive, and its all because of this simple engineering marvel! Great Video.

[boostedclied]

almost made me cry dude....

[todor2112]

how come this ain´t the world´s standard for auto engines?

[FlakeyWaffle]

because its not as reliable and consumes more gas than a v8

[ParadoxZero]

first of all know what you are talking about. its more reliable then any piston engine because it only has one moving part it is LESS likely to break down. and it doesconsume alot of gas, i ur constantly reving it past 4000 RPM, if you drive a rotary engine as a normal car and not rev it too high it actually get pretty good gas milage.

[mystikalecho]

so...if you drive an rx-8 normally, which has a 1.3 rotory engine, what would it's fuel consumption be equivalent to in terms of cylinder piston engine cars? eg. 2 L car? 2.4L? 3.0L?

[ParadoxZero]

i can't tell you for sure but i would say around 2.6L engine because of it having 3 combustion chambers per rotor it would be like a 2.6 6 cylinder engine. but if you want to know for sure ask someone with an RX-8

[arytonjames]

go back to school, and pay attention this time. flake.

[ParadoxZero]

because it does have some problems, but 2 of those problems were solved with the RX-8 RENESIS engine. the problem used to be the seals which worked like the piston rings, would burn out because they are constantly under changing degreee varying +/- 26 degrees. i want to read up on the RENESIS engine to understand it more, but i havn't found too many websites with info on it.

[snowrocket]

1)High tech materials and expensive machining costs have kept manufacturing costs high. 2)At full compression, the combustion chamber has square corners. This makes it extremely hard to efficiently burn all the fuel in the engine. A 1.3 liter rotary gets the same mileage as a 3.5 liter piston engine. Still, I've owned three rotaries and they're fun to drive fast! They're racing engines tamed for the street.

[willberg1]

Fuel usage is compaired to a v6 say 3L but the engine will burn as much fuel as you can dump into the intake, which is why you see alot of racers running rotory. The fuel usage on a stock rotory is still controlled and can get 30mpg older rxs.

[hoser4]

On a 400 mile trip to Los Angeles recently, my '86 RX-7 achieved 28MPG, even though the sticker says it should run only at 24MPG freeway. Careful attention to RPMs while cruising up hills, and a religious fervor for never using the brakes (preferring coasting when possible) helped greatly to achieve this. I still haven't gotten over 17MPG city though. Oh well. :)

[tripledonkey]

I set my RX7 auto on cruise control on a trip back from Wales where my girlfriend was following in our old diesel camper van. It was set to 55mph the whole way back. I measured 40mpg and was highly impressed. Sadly, under 'normal' driving conditions where I put my foot down I get around 18mpg.

[ncw812]

Love it

[Lauren1184]

The first car with this type of engine was a NSU(NeckarSUlm), today it belongs to Audi. The Audi (A2), A6 and A8 were produced there in Neckarsulm today.

[artstuff]

POP!!!

[ninorx7]

"objects in the mirror are piston driven"

Wankel Engines are the best...

[acr474747]

I owned an RX7 for awhile. It was the smoothest engine I have ever felt. I loved that car until a problem developed that no one could figure out.

[golem72002]

mathmaticly prefect almost.

[Rl831]

actually wankels where used in airplanes because of there high RPM capabilities not because of power. As matter of fact.... a Rotor engine produce less torque then piston rod and crank engine.

[FallenEmber]

Not to mention if the engine fails up in the air, it usually still has some sort of compression, enough for emergency landings.

[krizsaywhat]

but they got that top end and they rev so much faster..just because one full turn of the rotor is 3 revolutions of the drivetrain.

[arytonjames]

go back to school, and pay attention this time.

[NotalesS]

LOVE thats all i can say! die u piston lovers

[DemonicUnicorn]

me 2. funny that they use them in airplanes.... just soo powerful and light

[diesellover]

i love the wankel rotary motor
