racefan105 Unfortunately I haven't done any research so it was harder for me to understand. But i'm sure i could figure it out if I just did a bit of research :)
@Blaik Lewis No, that's incorrect. Wankel engines are surprisingly low maintenance, the fatal flaw in its design is very poor reliability and durability.
You realize that Mazda didn't invent this, right? The basic design was done by Felix Wankel in the 1920's, developed into a running engine by Wankel, and further developed into a practical engine by Hanns Dieter Paschke, both working at NSU in the 1950's. Mazda licensed the design in 1961, one of many companies to do so, but the only one to sell an engine of this design in large quantities.
Piston engines have a clear boundary between engine oil and combustion room, but rotaries do not, engine oil will be consumed during the rotation. Meanwhile, the apex seals are problematic due to their limited size and shape; the sealed area is also way larger than a piston engine. Note, the entire rotary needs to move smoothly but also be highly sealed with the two housings sandwiched.
Not only that, but within that combustion room you have all 4 of the steps of the Otto cycle happening simultaneously, so if you don't have near perfect sealing of the different regions of the chamber, the bleedover will hurt engine efficiency as well.
+Mostafa Mamdouh I second that, really well made and easy to understand even for someone with close to zero car knowledge. I was a bit sceptic at first because of no commentary, but as they say: A picture is worth a thousand words, and this was a damn fine picture! :)
I did a report in the 70's (4th grade) on the Wankel engine . I was so intrigued with this design I eventually purchased a mazda with the rotary engine. I never put a tachometer on that little motor, but I did take to some ridiculous RPMs. No floating valves! It wouldn't keep up with my big block chevy, but it would definitely scare the shit out of the driver, lol.

Bassotronics The apex seals are actually quite robust except in the area of detonation. Even stock seals will last over 100k on a turbo motor. Its the coating on the inside of the housings that can chip and peel over time.
Exactly why its a pos. And inherently flawed design. "Look at me dorito motor durrr.!" A motor that needs new apex seals every 80-90k miles is not what I would call revolutionary. ....PS. The rx8 looks like and is shit. No wonder they gave one for free on fear factor that one year lolz

Thanks for the animation. I have never managed to get my head around how rotaries work--especially how the rotor manages to retain a seal all the way around--Your video hit it right on the head.
Matt Rittman A 9 year old video still getting views also has the owner taking his time away from his day to reply to comments, you are a wonderful person my dude. Plus this video blew my mind! I always thought the combustion happened inside the triangular thingy
I'm always fascinated at the "rotary" engine technology since my childhood days… …far less complicated and with a much better output with lesser headaches to maintain in peek performance than a regular "piston" engine.
Understandable despite no voice in this short video. I did not know very well how the shaft stably rotates in the rotor, but now really got it. Thank you!
Video is great, but I personally would change the music to some sort of jazz or soul, that DnB just makes me wanna kick somebody and be way too focused and concentrated.
Done well sir!!!! I just heard about his engine at work today. Was intrigued on how it worked. Your video explained exactly what my curiosity was looking for!!!! 2 👍👍
Brilliant! (Both the engine design and your animation.....music is an added bonus!) It's so radically different than a conventional piston engine I wonder how in the heck the designer came up with the idea. When I think of the tight tolerances needed to create the combustion required, while doing it with a rotary part spinning at thousands of RPMs, it boggles my mind. Very, very cool!
The real doktorbimmer If that's your opinion that's cool- but you should research gyrotor pumps. Same operating principle. I spent considerable time studying these principles throughout engineering school.
Twister051 There is a book called "The Wankel Rotary Engine" by John B Hege. It goes though the very early days with the housing spinning around the rotor to function as a pump. Intake cam through the center of the engine if I remember correctly. Follows as it started to be developed as an engine, much of the work actually done by another person working for NSU. Talks about all the various licensed prototype engines various companies made. The Corvette even came in a one off mid engine rotary concept. The book wraps up with the Mazda history with the engine. They where really the only company to see any success with the design. Very good read. It is on the Google Play store.
ok let me find the fragments of my mind cause I've been a mechanic since a kid in my dad's shop,I'm 36 now!!!...after all these years now I know why he wouldn't work on these. the design is insane. hats off to the designer.
@AYE OK SURE you are false: all Wankel as excentric shaft because cannot run without (the pistons doest turn round in the trochoïde...) and a WW1 rotary engine (Gnome design) as a rotary engine block (prop is drive from block), the crankshaft is fixed...
@@CThyran An aircraft radial and an aircraft rotary look the same, but in a radial the cylinders are stationary and the crankshaft (with the prop attached) rotates, while in a rotary the cylinders (and the prop with them) rotate around a fixed crankshaft. This should be called a "rotary piston engine" (because the pistons rotate), and often is.
I really wanted to wrap my mind around how the output shaft worked and i couldnt find anything, but when i saw this video i found out so much more. Thank you!
What are the advantages and disadvantages of this type of engine? Just looking it seems like it would work a lot better than a conventional reciprocating piston, but clearly it doesn't or everyone would be using this time of engine.
When it was used in cars, it had some design and fundamental problems. It wouldn't perform very well at low temperature, would have to be rebuilt very often and reach the end of its lifetime by 250k miles. Google the history of Rotary Engines for more info.
Eric Taylor They are gas guzzlers, people with heavy feet are lucky to break 20mpg.. The emissions are terrible.. There are apex seals which last 150k at best and cost about 2500$ for the dealer to replace..The Rx-8 renesis also had some bad side seal issues which could fail as early as 80k or earlier..+ the 4cyl cars of today make more power.. The last wankel rotary was built in 2012 and there is no expectation of it coming back due to its inefficient design and lack of popularity.We went from building the 1st airplane to sending a man into space.., in less time then we spent trying to perfect the wankle. It was time for it to go.
Eric Taylor The disadvantage of this engine is that it doesn't last as long really. If you pay attention to the Rotary Engine, you can notice that there is a lot more stress in going through it's phases just to get to the Exhaustion. By stress, I mean Stress on one Rotor. The APEX Seals itself are something that needs to be replaced regularly because of this issue. That being said, anyone who tells you that they don't make any power or lack performance are not too well educated on this motor. The Rotary engine produces A LOT of power and it sacrifices longevity for performance. Think about it. This 2 Rotor Engine (13B) is classified as a 1.3L. Let that sink in for a little bit. The 1.3L in the well known world is actually equivalent to a 2.6L due to the amount of revolutions a Rotor outputs via Phases. It puts out 2-3times more than 1 Piston does. Which is why the Rotary also lacks longevity. The reason why it's only a 1.3L is purely because of it's displacement but in terms of power, it actually displaces what a 2.6L engine would displace. So when we speak of Rotaries... The number in front refers to their displacement SIZE. There's the 10A 1.0L, 12A 1.2L, 13B 1.3L, 20B 2.0L (3 Rotors) and 28B 2.8L (4 Rotors). Now multiply their displacement size by 2 and you get their power of displacement. Just think about it, a 26B, the size of a 2.6L engine but displacement is more like a 4.8L, it's obvious why they don't last that long. GREAT for Performance however. The engine itself does well with HP/Torque Ratios once it reaches the 20B phase. In general, Rotaries are a different animal and a different beast. You're comparing Apples and Oranges when compared to a Piston engine. They do indeed have issues of their own but that can be said about any car to be honest. May have more issues than a Piston car though HAHA. P.S. For anyone who thinks Rotaries are 100% poop. Better check yourself before you look like a fool, have you heard of the Le Mans 24 hour race? In 1991, Mazda entered the race with the 787B 2.6L (26B) Rotary engine and dominated the race. Beating Mercedes and Jaguar by a huge gap. HUGE. Want to know what happened? They later banned the Rotary Engine from Le Mans. So there you have it, performance and 24 hours of harsh abuse.
@@sandervanderkammen9230 The Renesis (RX-8 engine) was new for 2004... but yes, it has been a while. There are the Renesis II (2007) and Skyactiv-R (2011) designs, but neither has gone into production.
The real doktorbimmer Oh, well yeah I'm very noob in this subject! I just keep hearing one my friend saying that his car it's a 2.0 car and it consumes a lot of fuel. (Ford Taurus) And he says that 1.6 ones burn a lot less, (he is a noob too, btw) So I saw this Mazda rx-7 FC3S and 1.3 seems pretty less, but yeah, it can burn low quantity but faster and in teh end it's the same... :/
How did U calculate this ? When it has 650 cc volume in one chamber and there is a ignition every 60 degrees like on a 12 cylinder recipro it must have 12 X 650 = 7800 = 7,8 L or not ? Actually the german government gave up this to calculate a displacement. In my papers of my RX 7 FC turbo from 1988 is stated: Hubraum - keiner - Wankelmotor ( displacement- none - Wankel- Engine )
I believe what he meant that they fire once every ONE rotation of the e shaft. yes, they are 4 stroke but are geared as 2 stroke. even if we use the 1.3L config for displacement, idk rather call it 2.6L for fair as they do double the combustions in one e shaft turn. hey, that's just my opinion. hope to get a rx7 (fc/fd) when I graduate.
ayyyyyyyyy man thanks for the good reply. but i was wondering if you could elaborate more on the degrees thing as i really did not understand. further more, I'm not the power type of guy and more of the experience type of guy. I've been researching the rotary engine and all its flaws (which i believe are due to yet to be discovered materials). it has something going for it in terms of maintenance. it needs at least 2 times to care and asks you to have fun with it in order to extend its life span (taking it to the crazy high redline). also for street purposes, illl probably buy one who blown engine for dirt cheap and rebuild it myself instead of spending the same money on a running one that i have no idea how it has been treated. i can tell you have experience on it from your huge amount of relatively "negative" comments on the engine. but your language seems to tell a different story to that "negativity".
+Asif Ifas it was invented in 1924, there was already engines based on pistons, so the idea couldn compete with the standrads that were already established.
Nice CGI, well done! Is there a prototype of that engine? Also, it would be cool to see R&D involving something else than fossil fuel combustion, but that's another topic. EDIT - From Wikipedia : "Sarich worked on the concept for a number of years without ever producing a production engine. A prototype was demonstrated, running on the bench with no load. The engine, which produces very high revs, has only one moving part. It can _supposedly be powered by compressed air or steam and can be run as a pump_. Only one "bench prototype" has been built, which worked, but without any load though.
doktorbimmer im sure thoses rx models still HAVE their wankel engine. unless morons like you were looking after them and destroyed them, then went out on a rampage on YT to prove a point and state the flaws in wankel engine without much understanding of how they work..
The real doktorbimmer damn dude, HAVE, present tense. Stop trolling all these comments. Just because they aren't manufactured anymore doesn't mean all of the RX7s magically disappeared
A friend of mine bought an RX 8, and he claimed that the engine could achieve very high rpms because, unlike a piston engine, the rotors could spin in one direction without having to overcome negative momentum of going backward with every stroke. That made sense to me. But he also said that while the engine could therefore deliver more torque, it was less fuel efficient than an engine with roughly equal combustion volume. That didn't make sense to me. Is that right? If so, why, and if not, why not?
+kev3d Yep, thats right. It uses more fuel simply because its running at higher revs. also it gets through lots of oil as its needed for the seals on the rotor.
+The real doktorbimmer I have a good question for you: Why are you on almost every technical video involved with rotaries? And why are you telling lies and starting arguments with people? Just cut you crap and and do some proper research, not what ever 1950's garbage you look at, and do yourself a favor and be the educated one here.
+NipNip The displacement of a rotary is skewed. When the first Wankels were built by the Getman company NSU, their displacement was measured by including all the chambers. In the late 50s, Max Bentele visited them and persuaded them to only count 1 chamber per rotor to circumvent European taxes on displacement. Later on in racing equate them to 4 stroke piston engines, 2 chambers per rotor were used, basing volume of an engine on chambers that completed a full combustion cycle in 2 crank rotations. To use a 13b as an example.... It has 650cc combustion chambers and 2 rotors. Using the Bentele "tax evasion" method, it gets labeled as a 1.3L (only 2 combustion chambers counted). Using the original method, it's a 3.9L (all 6 combustion chambers counted). Using the method inspired from racing sanctioning bodies, it's a 2.6L (4 combustion chambers completed cycles in 2 crankshaft rotations). The rotary is ingenious for how much displacement it has in a tiny package.
Luke Molnar Short for "gasoline." Just a different word for the same thing. Like, Americans have "acetaminophen" and Europeans have "paracetamol." Same shit, different word.
Luke Molnar Why do you call it "petrol" which is short for petroleum? I've never seen a car run on crude oil. I have seen cars run on "gas" which is short for gasoline...
@AYE OK SURE you don't as well, that's true that both Wankel and mazda are the ones who come up with the idea but they couldn't manage to make it work, and the mean problem for them was that the design blocked within the first movement, it couldn't turn. Just until the Moroccan Abdullah Shakroun came up with the solution. So I think that he's the inventor, since there is no innovation without making the invention possible.
At the same time your burning oil cause the walls have to be lubricated in order to keep it from seizing. So its more money out of your pocket for every quart of oil you put in it. Just saying

One of the best display of animations to perfectly describe how a rotary engine works, well done, even after 13 years!
By far the best explanation video I have seen. Tried to tell my girlfriend how different a rotary engine was and this worked out perfect for me.
I'm here for the same reason LOL
Thanks for the animation. I have never managed to get my head around how rotaries work--especially how the rotor manages to retain a seal all the way around--Your video hit it right on the head.
Thank you very much! I really appreciate that!
Matt Rittman i liked the bit when the triangle spun around in the circle.
Excellent video Matt! I've often wondered how the rotary engine works. Great animation and illustration! Thanks.
Just curious to know , How much time require to create the whole animation from scratch? Btw amazing videos
Depends. If you count creating computers and the software, probably a very long time.
I think this engine is more proper solution for aircrafts rather than terrestrial powertrains. Astonishing video.
Most definitely
What about 15 years

RUclips: suggests something made 12 years ago
Everyone: well well well lets find out then
I had a video from 2009 from random shts I never seen or have since 2014 like bruh.
I'm always fascinated at the "rotary" engine technology since my childhood days… …far less complicated and with a much better output with lesser headaches to maintain in peek performance than a regular "piston" engine.
Wankel engines are obsolete because they cannot match the efficiency, performance or reliability of reciprocating engines.
Understandable despite no voice in this short video. I did not know very well how the shaft stably rotates in the rotor, but now really got it. Thank you!
Dude awesome. Great animation and great sound track. A little DnB ties it all together.

@@LayJD_ looking for it as well
It’s very cool to see a unique engine in action like this!!
It's very simple, yet so complex. I'm sure the dimensions have to be more precise than a piston engine
I drove the 12A and 13B Mazda rotary engines for years. They were fun to drive. Every time the secondary rotor kicks in it's always a thrill.
Done well sir!!!! I just heard about his engine at work today. Was intrigued on how it worked. Your video explained exactly what my curiosity was looking for!!!! 2 👍👍
Such a smart design
Just insane this engine even works.
It may not have been the most reliable and fuel efficient engine, but it's one damn cool piece of work
Dorito legend lives on
Creator is Real Boss
amazing work, i got what rotary engine is in 4 minutes thanks
This how you learn more from You Tube than college
13 years later and you are still the most watched video on this. Haha, thank you.
That’s crazy, I thought for sure someone would have come along and done a WAY better one!
Very well put together video and quite informative. Thank you for the time and effort you put in to making a quality presentation!
Thank you!
Brilliant! (Both the engine design and your animation.....music is an added bonus!) It's so radically different than a conventional piston engine I wonder how in the heck the designer came up with the idea. When I think of the tight tolerances needed to create the combustion required, while doing it with a rotary part spinning at thousands of RPMs, it boggles my mind. Very, very cool!
Thank you very much! I spent a long time on the animation! Wish it was HD :/
Twister051
It was originally a water pump, similar to a gyrotor pump.
The real doktorbimmer
If that's your opinion that's cool- but you should research gyrotor pumps. Same operating principle. I spent considerable time studying these principles throughout engineering school.
Joko Engineeringhelp Gyrotor pumps... Maybe where Elvis got the idea!
Twister051 There is a book called "The Wankel Rotary Engine" by John B Hege. It goes though the very early days with the housing spinning around the rotor to function as a pump. Intake cam through the center of the engine if I remember correctly. Follows as it started to be developed as an engine, much of the work actually done by another person working for NSU. Talks about all the various licensed prototype engines various companies made. The Corvette even came in a one off mid engine rotary concept. The book wraps up with the Mazda history with the engine. They where really the only company to see any success with the design. Very good read. It is on the Google Play store.
Your animation skills are AMAZING! Your content is so insightful. Thanks for the great content man!
Thank you so much, seriously! 🙌🏼
ok let me find the fragments of my mind cause I've been a mechanic since a kid in my dad's shop,I'm 36 now!!!...after all these years now I know why he wouldn't work on these. the design is insane. hats off to the designer.

So this is the lore of rotary engines, fascinating.
This is a Wankel engine
Pretty ingenious
And impractical

Same boi😂
you should call this Wankel engine instead of rotary engine because that would be way more specific. rotary engines can also be built with cylinders
@AYE OK SURE you are false: all Wankel as excentric shaft because cannot run without (the pistons doest turn round in the trochoïde...) and a WW1 rotary engine (Gnome design) as a rotary engine block (prop is drive from block), the crankshaft is fixed...
@@leneanderthalien An airplane engine with the pistons in a circle around the propeller is called a radial not a rotary.
@@CThyran Wow! You don't have a clue what a ROTARY engine is.
@@sandervanderkammen9230 Look at was analyste was talking about before opening your trap.
@@CThyran An aircraft radial and an aircraft rotary look the same, but in a radial the cylinders are stationary and the crankshaft (with the prop attached) rotates, while in a rotary the cylinders (and the prop with them) rotate around a fixed crankshaft.
This should be called a "rotary piston engine" (because the pistons rotate), and often is.
I really wanted to wrap my mind around how the output shaft worked and i couldnt find anything, but when i saw this video i found out so much more. Thank you!
What are the advantages and disadvantages of this type of engine? Just looking it seems like it would work a lot better than a conventional reciprocating piston, but clearly it doesn't or everyone would be using this time of engine.
When it was used in cars, it had some design and fundamental problems. It wouldn't perform very well at low temperature, would have to be rebuilt very often and reach the end of its lifetime by 250k miles. Google the history of Rotary Engines for more info.
That Guy With the Pointlessly Long Username That You Are Wasting Your Time Reading Right Now
Thanks, love the username by the way.
Eric Taylor They are gas guzzlers, people with heavy feet are lucky to break 20mpg.. The emissions are terrible.. There are apex seals which last 150k at best and cost about 2500$ for the dealer to replace..The Rx-8 renesis also had some bad side seal issues which could fail as early as 80k or earlier..+ the 4cyl cars of today make more power..
The last wankel rotary was built in 2012 and there is no expectation of it coming back due to its inefficient design and lack of popularity.We went from building the 1st airplane to sending a man into space.., in less time then we spent trying to perfect the wankle. It was time for it to go.
Eric Taylor The disadvantage of this engine is that it doesn't last as long really. If you pay attention to the Rotary Engine, you can notice that there is a lot more stress in going through it's phases just to get to the Exhaustion. By stress, I mean Stress on one Rotor. The APEX Seals itself are something that needs to be replaced regularly because of this issue.
That being said, anyone who tells you that they don't make any power or lack performance are not too well educated on this motor. The Rotary engine produces A LOT of power and it sacrifices longevity for performance. Think about it. This 2 Rotor Engine (13B) is classified as a 1.3L. Let that sink in for a little bit. The 1.3L in the well known world is actually equivalent to a 2.6L due to the amount of revolutions a Rotor outputs via Phases. It puts out 2-3times more than 1 Piston does. Which is why the Rotary also lacks longevity. The reason why it's only a 1.3L is purely because of it's displacement but in terms of power, it actually displaces what a 2.6L engine would displace.
So when we speak of Rotaries... The number in front refers to their displacement SIZE. There's the 10A 1.0L, 12A 1.2L, 13B 1.3L, 20B 2.0L (3 Rotors) and 28B 2.8L (4 Rotors). Now multiply their displacement size by 2 and you get their power of displacement. Just think about it, a 26B, the size of a 2.6L engine but displacement is more like a 4.8L, it's obvious why they don't last that long. GREAT for Performance however. The engine itself does well with HP/Torque Ratios once it reaches the 20B phase.
In general, Rotaries are a different animal and a different beast. You're comparing Apples and Oranges when compared to a Piston engine. They do indeed have issues of their own but that can be said about any car to be honest. May have more issues than a Piston car though HAHA.
P.S. For anyone who thinks Rotaries are 100% poop. Better check yourself before you look like a fool, have you heard of the Le Mans 24 hour race? In 1991, Mazda entered the race with the 787B 2.6L (26B) Rotary engine and dominated the race. Beating Mercedes and Jaguar by a huge gap. HUGE. Want to know what happened? They later banned the Rotary Engine from Le Mans. So there you have it, performance and 24 hours of harsh abuse.
Advantage: compact size and power density.
Disadvantage: reliability and emissions.
Awesome engine. It's different and that makes it cool. Long live the RX7 and RX8. I hope mazda brings it back.
Mazda hasn't unveiled a new production Wankel engine in over a quarter of a century...
@@sandervanderkammen9230 The Renesis (RX-8 engine) was new for 2004... but yes, it has been a while. There are the Renesis II (2007) and Skyactiv-R (2011) designs, but neither has gone into production.
They do burn a lot of oil
:(
the motor is 1.3 , so I guess we compensate with less fuel use. I hope
I want a Rx7 so bad...
The real doktorbimmer Oh, well yeah I'm very noob in this subject! I just keep hearing one my friend saying that his car it's a 2.0 car and it consumes a lot of fuel. (Ford Taurus) And he says that 1.6 ones burn a lot less, (he is a noob too, btw)
So I saw this Mazda rx-7 FC3S and 1.3 seems pretty less, but yeah, it can burn low quantity but faster and in teh end it's the same... :/
How did U calculate this ? When it has 650 cc volume in one chamber and there is a ignition every 60 degrees like on a 12 cylinder recipro it must have 12 X 650 = 7800 = 7,8 L or not ? Actually the german government gave up this to calculate a displacement. In my papers of my RX 7 FC turbo from 1988 is stated: Hubraum - keiner - Wankelmotor ( displacement- none - Wankel- Engine )
I believe what he meant that they fire once every ONE rotation of the e shaft. yes, they are 4 stroke but are geared as 2 stroke. even if we use the 1.3L config for displacement, idk rather call it 2.6L for fair as they do double the combustions in one e shaft turn. hey, that's just my opinion. hope to get a rx7 (fc/fd) when I graduate.
ayyyyyyyyy man thanks for the good reply. but i was wondering if you could elaborate more on the degrees thing as i really did not understand. further more, I'm not the power type of guy and more of the experience type of guy. I've been researching the rotary engine and all its flaws (which i believe are due to yet to be discovered materials). it has something going for it in terms of maintenance. it needs at least 2 times to care and asks you to have fun with it in order to extend its life span (taking it to the crazy high redline). also for street purposes, illl probably buy one who blown engine for dirt cheap and rebuild it myself instead of spending the same money on a running one that i have no idea how it has been treated. i can tell you have experience on it from your huge amount of relatively "negative" comments on the engine. but your language seems to tell a different story to that "negativity".

Wankel hated this design.
I keep seeing the Coolant Jacket section like 3 times already
Nice CGI, well done! Is there a prototype of that engine? Also, it would be cool to see R&D involving something else than fossil fuel combustion, but that's another topic.
EDIT - From Wikipedia : "Sarich worked on the concept for a number of years without ever producing a production engine. A prototype was demonstrated, running on the bench with no load. The engine, which produces very high revs, has only one moving part. It can _supposedly be powered by compressed air or steam and can be run as a pump_.
Only one "bench prototype" has been built, which worked, but without any load though.

I can’t believe this was made 14 years ago and the quality is astounding
A friend of mine bought an RX 8, and he claimed that the engine could achieve very high rpms because, unlike a piston engine, the rotors could spin in one direction without having to overcome negative momentum of going backward with every stroke. That made sense to me. But he also said that while the engine could therefore deliver more torque, it was less fuel efficient than an engine with roughly equal combustion volume. That didn't make sense to me.
Is that right? If so, why, and if not, why not?
+kev3d Yep, thats right. It uses more fuel simply because its running at higher revs. also it gets through lots of oil as its needed for the seals on the rotor.
+NipNip Interesting. Thank you.
The real doktorbimmer
how can that be true when a small wankel engine produces almost double the power of a piston engine the same size?
+The real doktorbimmer I have a good question for you: Why are you on almost every technical video involved with rotaries? And why are you telling lies and starting arguments with people? Just cut you crap and and do some proper research, not what ever 1950's garbage you look at, and do yourself a favor and be the educated one here.
+NipNip The displacement of a rotary is skewed. When the first Wankels were built by the Getman company NSU, their displacement was measured by including all the chambers. In the late 50s, Max Bentele visited them and persuaded them to only count 1 chamber per rotor to circumvent European taxes on displacement. Later on in racing equate them to 4 stroke piston engines, 2 chambers per rotor were used, basing volume of an engine on chambers that completed a full combustion cycle in 2 crank rotations.
To use a 13b as an example....
It has 650cc combustion chambers and 2 rotors.
Using the Bentele "tax evasion" method, it gets labeled as a 1.3L (only 2 combustion chambers counted).
Using the original method, it's a 3.9L (all 6 combustion chambers counted).
Using the method inspired from racing sanctioning bodies, it's a 2.6L (4 combustion chambers completed cycles in 2 crankshaft rotations).
The rotary is ingenious for how much displacement it has in a tiny package.
The down side is their not efficient, Had a RX8 used gas like a V8 Camero
Why do Americans say 'gas' when most the time they actually mean petrol or petroleum? Or even 'fuel' makes more sense. Just sayin.
Luke Molnar
Short for "gasoline." Just a different word for the same thing. Like, Americans have "acetaminophen" and Europeans have "paracetamol." Same shit, different word.
Oh ok so 'Gas' doesn't mean gas. Got it!
Luke Molnar
It means what it means: gasoline.
Luke Molnar Why do you call it "petrol" which is short for petroleum? I've never seen a car run on crude oil. I have seen cars run on "gas" which is short for gasoline...
you are legend

Haha thanks :)
A perfect animation that clearly explains how the rotary engine works👍👍👍
The idea of this engine is for the Moroccan inventor Abdullah Shakroun
@AYE OK SURE you don't as well, that's true that both Wankel and mazda are the ones who come up with the idea but they couldn't manage to make it work, and the mean problem for them was that the design blocked within the first movement, it couldn't turn. Just until the Moroccan Abdullah Shakroun came up with the solution. So I think that he's the inventor, since there is no innovation without making the invention possible.

At the same time your burning oil cause the walls have to be lubricated in order to keep it from seizing. So its more money out of your pocket for every quart of oil you put in it. Just saying
