- In the video, we will learn how an automobile rotary engine works, using the example of the structure of a Wankel engine. This engine was massively used in such cars as the Mazda RX-7 and RX-8. In 2012, the mass production of this engine ceased. In 2023, Mazda announced the return of this engine as a generator in the MX-30 R-EV.

Greetings! Wanted to post this video later. But given the announcement of the use of a rotary engine as a generator in the Mazda MX-30 R-EV, the right time to post the video is now:) Enjoy watching.
P.S. I don't know English very well, so please write comments on translation and/or voice acting. This will help make the video better! Thanks)
I've owned four RX7s since 1978 and this is the best, most concise vid on Wankel engines that I have watched.
owning four? what a dream
This is the most clear, correct, and complete Wankel rotary internal operation video that I have seen.
Except he got the name wrong. The intire engine rotates on a rotary.
@mr.donut2.085 there are many types of engine which are correctly described as "rotary". The antique reciprocating piston engine type with radially arranged cylinders rotating about a fixed crankshaft - the one to which you are referring - is a "rotary", because the cylinders rotate. Wankel's design with a three-sided piston orbiting inside an epitrochoidal housing is "rotary" because the piston rotates (instead of reciprocating). There are various other engines in which the housing or the pistons rotate, and so they are also "rotary".
By far the most successful manufacturer of Wankel-type engines in history, worldwide, is Mazda. They prefer not to use the "Wankel" name (Felix Wankel was not part of Mazda, and not even Japanese), so they call them... Mazda rotary engines. That's perfectly valid.
He even put "(Wankel engine)" in the title to make it perfectly clear which of the many rotary engines is being described in the video.
The Wankel KKM57 is NOT a Rotary type engine.
Mazda never manufactured the DKM54 or any other Rotary type engine.
@WilhelmKarsten The block does not rotate, but it is a rotary piston engine, meaning that the piston rotates rather than reciprocating.
@@brianb-p6586 It's not valid, and clearly an example where street slang and patois is absolutely false and deceiving.
Mazda became a Wankel-NSU licensee in 1961, paying _NSU Motorenwerkes GmbH._ to use the Wankel name, logo and pay a 40% royalty for ever Wankel KKM57 engine sold.
Mazda used the Wankel name and it appeared cast into every engine for the duration of the licensing agreement.
When the agreement ended, Mazda conjured up a new registered trademark "Mazda Rotary®" to avoid paying for the NSU (now Audi) trademark.
And questions son?
Thanks for all the videos, they are great!
Amazing ! Great explanation!
Very well made video, this teached me alot, thx😁
Nice animations!
another amazing videos..
Excellent explanation and animation of the process
3:55 Where's the "following videos", please, it's so good! 😭
Beautiful machine
This is very interesting
i love cars and wanna learn about them,you are a veryy underrated channel,i thought you had liek 300 k subs or more
Thanks for appreciating!)
I just started my way in the English-speaking segment, I hope the subscribers will slowly go up, I will be very glad to everyone :)
P.S. In their native language, in about 4 years, 400k subscribers signed up.
Please make a complete video on cooling system and suspension system..... 🙏
Very very good visal repentation of the how it works because it would take me hours to figure oit how this works on my own mostly because i work on the common 4 stroke engines (car engines) all ways wanted to know so thx
Amazing innovation 3D engines
Nice one
Could the exhaust pressure from first rota turned the second rotor. The animation is really good.
Now we have the Dingel Water Engine...Phil German Ingenuity...
Der Erfinder des Kreiskolbenmotor war Hanns Dieter Paschke (NSU Motorenwerke) , erst seine Konstruktion war überhaupt verkaufsfähig bzw.für den Einbau ins Auto geeignet. Felix Wankel's Drehkolbenmotor war eine Katastrophe die niemals ein Fahrzeug zuverlässig angetrieben hätte.
Der Wankelmotor müsste eigentlich "Paschke Motor" heißen .
I agree that Wankel's Drehkolbenmotor (DKM, "rotary piston engine") was not viable, and that the Kreiskolbenmotor (KKM, "circuitous piston engine") designed by Hanns-Dieter Paschke is the design used in all successful applications. While naming these engines "Wankel-Paschke" would make sense to me, credit for the fundamental concept of a three-sided rotor orbiting in an epitrochoidal housing as an engine belongs to Wankel; Paschke never would have designed the KKM if not for Wankel's work and the issues with his DKM design.
これを考えた人は天才！！！
A German engineer Felix Wankel first came up with the idea as a compressor in the 1920s. It was then turned into supercharger for motorcycles in the motorcyclist in the early 1950s. By the mid 1950s he was convinced he could turn it into an engine. By the late 1950s thru had their first prototype.
So before it was an actual engine, it was first a compressor, then a supercharger, then an engine.

This is informative but I was searching for how half bridged rotary engines work and what is the difference between a half bridged rotary and a normal rotary engine
Pump, control valve & swing &track motor ,pto pump working animation of excavator plz sir make a video on it .
Does the rotors friction against the middle / front and rear housing?
Yes, the rotors have seals along each curved edge (three on each side of each rotor) which slide against the end and intermediate housings (as well as the tip seals that slide against the rotor housing). The rotor itself does not touch any of housings.

Can i get the cooling system of this with two radiators
Instructions unclear i made a nuke
There are more than one kinds of rotary engines, so Wankel is not the rotary engine. It is a rotary engine. The liquid piston engine is a rotary engine.
3:24, rather than 720 degrees of rotation if it's compared to a standard 4 cycle engine. (not 360) a v-8 would have combustion every 90 degrees, a 2 rotor Wankel would be every 60.
Is it a good thing ?
it's good to have accurate information in an information video. I believe more frequent combustion is good. @@bigdaddyyute6472
There is one power stroke per rotor for each full turn of the eccentric shaft, so that's every 180 degrees for a two-rotor (that full rotation of the eccentric shaft is 120° of rotor rotation, as shown @3:24).
Any 4-stroke reciprocating piston engine does take two crankshaft turns (720°) for a full cycle; a Wankel rotary takes three eccentric shaft turns (1080°) for a full cycle (to get all three faces of the rotor through a cycle). That means:
V8: 720° / 8 cylinders = 90° per power stroke
2-rotor Wankel: 1080° / 6 chambers = 180° per power stroke
@@bigdaddyyute6472 the only significance is that more frequent power pulses mean smoother power delivery (so more cylinders is always smoother), and that in any 4-stroke the power pulse is less than 1/4 of the cycle so more than 4 cylinders (or rotary chambers) are needed for continuous power.
A two-rotor Wankel is equivalent to a 6-cylinder reciprocating piston 4-stroke engine in power pulse smoothness.
Are they inefficient bc the shaft spins at a high rpm then having to move what looks like gearing followed by the dorito?
No. The higher (compared to a typical 4-stroke reciprocating piston engine) main shaft speed is not a problem for efficiency, and neither is the gearing. The main problem with Wankel engine efficiency is the shape of the combustion chamber.
@@brianb-p6586It's a very serious problem and is the reason why the Wankel engine has such low mechanical efficiency
@WilhelmKarsten no, but I suppose if you're ignoring physical reality and working without data you can believe what you want.
@@brianb-p6586 No, it's basic geometry and mechanical engineering.
The piston of a reciprocating engine acts upon the crankshaft with a mechanical advantage (leverage) while the piston of the Wankel KKM57 engine operates with a mechanical disadvantage.
Any questions?
@@WilhelmKarsten I'm sorry you have difficulty understanding the geometry, but it still doesn't change physical reality.
The rotary engine is one of the best polution machine to every waste fuel. A 1.3 liter has the consumption of 5.7 liter engine is a major problem from factory engineers dance.
yes indeed...... only one of the three sides is responsible for the strokes....... totally accurate...... that was sarcasm a Rotary experiences three power strokes per rotation..... but it was good vid i guess
I just learn there is inline 3, inline 4, Boxer 4, V4, Inline 5, inline 6, boxer 6, Flat plne V6, Cross Plane V6, Vr6 , FPV8, CPV8, Inline 8, FPV10, CPV10, FPV12, CPV12, W12, W16, V16 and now i have to learn about another kind of Engine?
Which cars have this type of engine ?
Mazda rx7 & rx8
Here are some actual productiuon cars: NSU Spyder and Ro 80, Mazda Cosmos Sports Car, Mazda R100 Coupe, Mazda 'RX' series - RX2-3-4-5-7 and 8, and... the Citroën GS Birotor, to name a few. There were also some other production mazdas in there as well. Other manufacturers also made running prototypes for testing and investigation purposes.
Wankel engines have been out of production since June 2012.
💕💕💘💘❤❤
ok
Resumen: brap brap brap brap brap
#1408hpgoalpossible.
il est possible d'améliorer encore le moteur Wankel sur son étanchéité, son refroidissement, et surtout de diminuer le nombre de joints sur les multi rotors
No, it is an obsolete technology that reached the end of its development potential
@@sandervanderkammen9230 ok je suis d'accord pour la détente des gaz donc un mauvais rendement, mais pour l'architecture il est encore possible de l'améliorer
