- This is a model of a rotary engine (Wankel engine) made with Lego bricks. The model is based on the Mazda 13B-MSP "RENESIS" engine, which is mounted in the car Mazda RX-8.
This model is submitted to the Lego Ideas (August 19). I would like to ask your support:. I would like to ask your support:

This is the kind of stuff that Lego should sell as a product.
True, this stuff, and not this Ducati Race Bike (Only good for Parts restock) junk!
This could easily be a Lego Ideas set. And I would totally buy at least two.
Lego: 18-99
yes
I’d buy it. But I do have to say I built the bike. And it’s dope af
The addition of the light brick really makes this an excellent model. Good work.
LEGO technic: rebuilding modern technology with horrendous tolerances!
(In all honesty, I was impressed to see this made!)
Gotta say, thx for explaining to me how a rotary works! Also very nice build. Im pretty young too, so using legos rally helped!
*slightly lower tolerances than an actual rotary engine
@@sneab-jp6du That is true 😆 I did read once how rotary engines have a problem with the engine block heating unevenly...
Akiyuki! you are a genius!
Not to be meant but the rotary engine is old not new
The demonstration of the chamber shape @1:36 was absolutely beautiful!
lego has so much potential in teaching kids the basics of mechanics and electronics, this is the kind of stuff I'd love to see in schools
In my old school we had a robotics class.
I never got to take the class but when ever I had free time like during recess or before school hours I'd enter the classroom and play around with the vast legos, building and writing scripts to make the robots move around and complete tasks
Bro if THIS is the basics, I'm scared.
Instead we learn about 6 oranges that cost $99 for some reason is better than 8 oranges that cost $78. And how many John needs to buy for his dog to feed to his wife, that can eat 2 oranges at 8 miles per hour. Then we need to know how many seconds it will take to snort 87 grams of cocaine, which is what the person who that of these problems is on. Now we divide them to know how many cars are on highway 32 when it is 8:37.
ロータリーエンジンの動きを完全再限していますね。素晴らしい出来映えですお疲れ様です👏
Mazda: goes “hmmmmm...”
Lego at full speed goes: “whiRRRRR TICK TICK TICK TICK TICK....”
Braaaapppppppp
They need a Mazda Lego car that works properly with A controller
MORE PAA-WOOR BABY
Sorry who called?
@@deluxelemur do you watch donut?
3:14 we all waited for this lego BRAP BRAP BRAP sound😂🔥
As an RX-8 owner I appreciate the creative way you illustrated how this amazing engine operates! I just wish I could change MY Apex seals that easily!! Lol
To quote one of my friends, even the Wenkel doesn't like the Wenkel design. Physics loves to break it.
@@kirknay Wankel might not be fond of being a Wankel but god does she sound awesome! I mean, i dunno if ive ever heard a single rotor, and only know the 2, 3, and 4, but they all sound great up there at 10k+ rpm.
@@PRXFpv Ikr, there's a guy around where I live with a 4 rotor RX7 with a huge turbo on it, it sounds almost identical to a Mazda 787B, especially at idle. It's incredible.
Same here my man! 😁
@@kirknay that's why you gotta add another rotor :D It also doesn't like being a wankel because too much heat is bad but it makes a lot of heat, and almost all of it on one side of the engine

This would actually be a Rx8 engine or a 13b msp not the fd rx7 engine a 13b rew do to the side exhaust ports. 13b rew has peripheral exhaust ports.
技術だけじゃなくて見せ方、配色なんかも素晴らしい…

I always forget about this channel for a month or so, then return to find he’s been up to even crazier projects while I was out
This is literally the coolest thing I have seen made out of a child’s toy from the 70’s holy cow. The timings, maths, detail and coordination of the motion, sparks and more is mind blowing. Make this into a kit for me please lol!
Actually 60s lol, thanks courtesy of the replies!
It's on lego ideas there's a link at the end you should vote for it
It's not 70s lmao
@@Kuri0 yeah its 60s
Welp that’s true lol, just went through my uncles old toys recently and found an original 70s excavator kit. Cheers for pointing that out lads
@@mickb1470 This is literally the nicest reply section I have ever seen.
ちょうどLEGOでエンジン作ろうとしてたので助かりました！
That is most impressive! You really captured the motion perfectly
That was really cool but it was driving me insaine that the walls didn't stay in contact with the apex seals
I think that shape is just impossible to do in lego lol
Lol it’s realistic because most rx8’s don’t either 🤣
@@thereagan2001 LMAO
You should really submit this to Lego Ideas. It's amazing
The lego ideas link is in the description, currently on 108 votes
Thank you for notifying, it wasn't there four days ago
Aaaaaaaaaaaaayaaaayaaaaayaaaayaaaaauaaaauaaaaaayaaaaaaauaaaaauaaaayaaaaaa!!!!!!!!!!!!!!1!!!!!!2!!!!!!!!3!!!!4!!!5!! Oh ny
Came here just to admire someone's dedication. Little did I know this video would include the station gear ratio that would help me with my CAD project. SUPER AWESOME!
this thing has probably got about as much compression as my rx8's engine...
None???
Sander Van der Kammen It‘s a joke about the Apex seal lifetime
@@qymaenjajshelaalgrievous I wish it was a joke
Peter Armour I know
I just died😂
Guys this is almost halfway to 1000 supports on lego ideas, lets try and get this a set!
Looks like your apex seals went bad mid build, such a shame
It's a Rotary, it would get broken anyways
@@thytor756 Who you kidding. Rotaries are darn near bullet proof. It is everything around them that breaks. Usually from all the heat they produce. Mine was good well over 100K it was the radiator that finally broke that made me give it up. And only because replacing the radiator cost more than the car was worth.
@@koloth5139 sure bud
Koloth Most cars easily reach 300k. I believe the big failing point of wankel engines are those seals.
@@Engineer9736 And a rotary will easily reach 300k as well if you're doing the maintenance. The seals do wear, but not any faster than piston rings if you're changing your oil properly.
Lego Ryosuke Takahashi wants to know your location
That was the best explanation of how one of those engines works that I've ever seen.

If you listen closely you can kinda hear the exact same brap brap brap noise a rotary makes but higher pitched with I think it really cool
you are the best lego builder ive ever seen! keep up the good work.
if only lego had the bricks to make the proper rotor housing shape i reckon it could nearly hold some compression. insane dedication here
Next project: a real Capacitor Flux with Lego 🤣
Good idea!
Flux Capacitor you mean. Lol.
@@general_hammond right lol.
I was learning rotary engine when this came out. Why must everything i was thinking of became reality?!
*cough* TH-cam Algorithm is everywhere *cough*
Yes

Before i watched this video, i didnt know how the Dorito put the power to the transmission, but when you showed me, now i know. Thank you dude
Showing the combustion using the red light was genius!
this is what a lego should be. teaching people with fun
ありがとう🤗
とても良い物を観させて貰いました🎵
very thanks 🤗🤗
ロータリーエンジンって言ったらやっぱFDだね！
Wow! What an incredible build - and that light brick that you added near the end of the video finished it off perfectly! Keep up the great work!
Impressively accurate simulation of how the real Wankel rotary engine works, good job 👍
Plot twist: He blew apex seals shortly after the video
I'm an R3 owner and I approve this message.
As a long time rotary car fan (my first rotary car was an 85 RX-7 GSL) and even longer LEGO enthusiast, I salute you for an awesome video!
I've been wondering, how does this type of car engine work? You say you're a long time fan of these types, and I was hoping you could share some insight
TrainBoy227 YT Just like a typical 4 stroke engine that uses the up and down motion of the cylinders, connected to the crank shaft, to turn the drive shaft, the spinning rotors are connected to a crank shaft which in turns drives the drive shaft. Rotary engines have the benefit of putting out more horsepower for a given size engine (the Mazda R8’s 1.3 liter engine putting out 232 hp). Being smaller, the engines can be mounted further back (behind the front wheels) and lower to the ground meaning you can design a better handling car around a rotary engine. Also, rotary engines also have fewer parts.
However, rotaries are not as fuel efficient as their four stroke counterparts and require more dedicated maintenance. Failure to perform routine maintenance, like oil changes will result in premature failure. Lastly, the seals at the tips of rotors (the apex seals) will only last so long (60k to 100k miles - maybe a little longer if the engine not driven hard) and need to be replaced. However to do so means pulling out the engine and opening it up to access the apex seals.
All in all, rotaries are quirky engines and require more attention but they are amazing to drive and they love to be pushed to their redline. It is not an engine for an every day commuter that just wants a point A to point B vehicle, it’s an engine for a driving enthusiast that will appreciate its quirk and give it the maintenance it needs.
@@AstroNerd Another thing to point out is that the actual rotors inside the engine rotate at 1/3rd of the speed of the "crank" aka eccentric shaft, therefore if one of these were to operate at 10,000 rpm for example, the rotors themselves would rotate at less than 4,300 rpm to be precise.
Are you an engineer? What kind of engineer? Do you work in architecture? Are you a toy developer designer?
Sorry for the questions but this work is beyond professional. This can't be considered a hobby anymore. It's a technical art. There's a lot of analysis done prior to these designs. It's too exhaustive.
The beauty this has can't be described by words.
Is it possible to get a part list cause this would be awesome to have on my desk?
Exactly!
same would love to build this
Support it on the LEGO page link
It's on lego ideas you should vote for ir
You literally just watched a tutorial
Not a Lego guy but damn! The light brick just throws this build over the top.
Akiyuki: makes Lego Wankel engine
Me: he can't make it brap, can he?
Akiyuki: 3:12
This looks awsome. When you take a first look at it, it looks like the real one.
Thank you for showing me how a Wankel engine works. Your build is relatively simple yet extremely strong for that motion. I am impressed yet again at your work. おめでとうございます
I wish Lego would partner with Mazda to make it a RX7 model featuring new rotary engine parts to go alongside the piston engine pieces we are accustomed to. Great job and video!
This is a masterpiece! I wouldn't even expected something like this, which makes it even better. Well done!
Well done! Should be mandatory teaching and hands-on experimenting for 12-15 year olds to “spark” some curiosity in engineering for those who might not know they’ve got a knack for this sort of thing.
Imagine if they made a functioning Lego car, that would be so cool.
Until it breaks immediately... Lol
And then you step on all the little pieces, yikes.
Assuming you've never seen this th-cam.com/video/n-RtJOfFlZU/w-d-xo.html
you seen this? th-cam.com/video/_ObE4_nMCjE/w-d-xo.html
somebody already did make a functioning lego car that runs on air.
I've seen people make go carts out of lego
The engine would have to be made out of metal legos and then the legos would have to be welded together.
The light detail really impressed me, I love it!

Me when I buy a RX-8: oh yes
Me when I watch this video: What am I doing with my life
What’s wrong with buying an RX-8?
This is the perfect followup to the last video. Thanks again for such amazing content
First, rotary mechanism is an absolute masterpiece. But making it as good as you did with Legos, is just amazing. This deserves a 👍.
2:53 made me whoa with understanding
Keep in mind that he only shows one side of the rotor (equivalent to one cylinder), for clarity. In reality, all three sides of the rotor act simultaneously, similar to a three-cylinder engine.
Pyrrha Nikos And with 2 rotors, super smooth.
And then they added the light that was synced to it.
@@timehunter9467 I know... my first car was an RX-7 FC. Still kick myself that I sold it...
@Pyrrha Nikos big oof, I’d like a 787B just because it’s got 4!
thank you very much i just understood how the shaft and the rotor are revolving at different rpms while fitted to each other i realised that they are not mounted but just fitted to move the center of the rotor around the peripheral of the shaft only thank you very much
When you did the last video I wondered if this was next. This is absolutely amazing. It's lovely to see such an accurate car engineering example done in your genius Lego execution.
Kids with Lego: I’m gonna build the coolest car ever
The quiet kid: *haha magic triangle goes weeeee*
AHAHAHAH
I was planning on making one of these but it wouldn't be nearly as good as this, you should release instructions I want to make one like this.
He has Lego Ideas page for this, you should go support him.
@@littlebigparardise9245 I definitely will then, but I have already started copying this one lol. I'd still buy it though.
You explained the way this machine works better than all of my google searches combined
So can i use this to replace the real rotary engine in my rx8?😂
in a lego rx8
Rx7too
The coolest thing I ever seen built out of plastic bricks
Loving this. Should also add everyone's favorite - The APEX seals :D
so this is how a Wankel engine works. nice. literally explained it better than any other vid on yt.
This guy is a genius, no clickbait, pure content 🤌🏼
The way you use the blinking red light really brings the piece together
Man I need this, doesn't represent the rotary's smoothness but god daymn I would love to see you bridge port it
I like how the rotary was sped up and sounded just like irl
WE MADE IT BOIS, this is the best lego creation of anyone so far
Wwwww I have no clue where the boys go and what time are they coming back home so

Best example yet of the rotary engine and the potential of Lego as an outstanding learning tool
まず最初のパーツがない
Me learning how a rotary engine works from this better than an engineering channel
Fun fact: he had to replace the apex seals after this presentation
my grandfather helped create the real thing ,, right before ww2 and coming to America from germany.. My grandfather was a master machinist/engineer who worked with wankel .. they were good friends.. did me no good though,,im homeless ,,, just nice knowing that you have famous relatives.
"Do the Brap-Brap"
Holt shit that visual from 2:53 really is perfect at explaining how combustion engine works,,kudos
*THE RX-7 BOYS WOULD LIKE TO KNOW YOUR LOCATION*
Thank you for finally being the first person to explain to me how a rotary engine works.
Зачем я смотрю это в 5 утра?
Everything about this video is just crisp.
**Mazda has entered the chat**
初めにこの仕組み作った人控えめに言って天才だわ
何食ってたらこんなの思いつくんだよ
Ya know, it amazes me that if you blocked off pretty much all source of air escaping, (except for the intake and outtake) then you could actually make something move with this engine.
the most beautiful engine ever made
Bin Asperger Autist und habe meine ganze Jugend mit Lego technik meinen Tag verbracht (Das waren noch schöne zeiten)
The editing on this aswell as the demonstrations. So goood
This is honestly one of the prettiest lego builds i have ever seen i would buy this as a set in a heartbeat
That LEGO rotary probably last just as long as the ones in the pre face lift rx8.
I think this video alone is what kicked started my love for cars
The red light was a nice addition.
This was actually really cool. The light at the end was a great add. This actually taught me how rotaries work.
That moment you realize the children’s toy you assembled at your dining table has better compression than your actual engine
