WANKEL ROTARY ENGINE - STOP MOTION

Rotary Engine Assemble & Working Video.
OS WANKEL ROTARY ENGINE 49PI

[@djmz1969]

The best video ever of a representation of how an engine works. Excellent!

[@Aleksanti]

It was about time someone did a HQ video on these engines. Great video!

[@bluepond]

I found your stop-motion animation both educational and beautiful.

[@doktorbimmer]

I found the title inaccurate and misleading, this is a Wankel type engine... not a rotary type

[@DavidCurryFilms]

The stopmotion wool to show the engine cycle was very clever! Beautiful engine too.

[@poptartheroes]

That fuel pump was sweet

[@captainwallard2788]

This is awesome. Seriously who downvotes something like this?!

[@bradleyj.fortner2203]

The stop motion work was impressive. This must have taken a minute to make. Thanks for all your effort, it was really cool.

[@iguy]

Thanks for the compliments. Have a nice day...

[@Trumplican]

one of the coolest engines ever! i think the rotary engine was way underrated and never really given a chance

[@JasonStaggs99]

Dragon800 The efficiency is sub par compared to a piston engine

[@Trumplican]

Im saying with more research and design it could have accomplished great feats. I'm not talking about efficiency either I'm talking power. Look at the power of the 13b in the rx-7. Now Imagine today's version of a 4 or 5 rotor rotary engine if given the attention the piston engine was given in the previous decades.

[@homemadelemonade976]

Yeah but the efficiency was bad, the rotating piece was tough to seal properly and the seals would burn out quickly and required frequent maitenance. Did i mentiom that it burned oil too? You had skyhigh emitions, poor reliability and it spent as much oil as it did fuel. It was never succesful for a reason.

[@BrokenLifeCycle]

I read up that it's being experimented on as an aircraft engine. Apparently the power to weight ratio was just too good to pass up.

[@Trumplican]

technically it was successful. the RX Mazda's were very successful in racing especially.And if more research was put into the design such as the corner, side, and apex seal improvement they would have done even better.

[@mohammedsami7080]

Now thats a powerful and cute baby engine

[@doktorbimmer]

Cute little toy.

[@wisikahn]

The best video without stupid narrations and unnecessary blabbing...

[@JpLabs1981]

It would look fantastic on an RX7 RC model.

[@doktorbimmer]

yeah, it would be unreliable just like a real RX-7 too

[@BuilditRideit]

I really appreciate the effort taken by you in making this video, as a creator myself I understand how labour intensive it might would have been, great job congratulations!!

[@mikmerl1]

enjoyable, educational nicely made video ............. well done dear fellow

[@rodri949]

The engine itself and the stop motion are so cool. And being a mini engine makes it even cooler!

[@jtsikkness8878]

most def a cool ass video, I knew the premise of a rotary engine but never knew exactly how they worked. thanks man, appreciate the knowledge buddy, and the stop motion was dope for sure....

[@isigo]

Wow, that must have been a lot of work, dude! Awesome!

[@binodmenahihu8104]

Awesome... Didn't know anything about rotary engines until I saw this video... But it seems this rotary engine creates more vibration than piston driven engines...

[@laluisbacksamaans5222]

its actualy opposite

[@binodmenahihu8104]

laluisback samaans it just randomly looked like a lot of vibration is going on here.. And does traditional clutch and gearing system works with it..???

[@deusexaethera]

If you look closely, it only produces a lot of vibration at idle, and that's because the carburetor doesn't allow adjusting the fuel mixture at idle. This engine was designed for model airplanes, and model airplane engines don't need to idle smoothly because they only idle before takeoff and after landing.

[@doktorbimmer]

*The triangular shaped piston is relatively heavy compared to a reciprocating one, this creates a high osculating moment. Larger Wankel engines have balance weights, mass dampers and heavy flywheels to control vibration.*

[@deusexaethera]

From the look of it, his engine is missing the Woodruff key that fits into a slot on the crankshaft to properly align the front counterweight.

[@leemilica]

I love the nitro full throttle banshee scream.

[@justshino]

Where's the 4-rotor Rob.... oh wait, wrong video. Sorry xD

[@devon8419]

Shinobu Oshino perfection right there. Have a like

[@yuuuuuubi]

I can just imagine the amount of time put into this, good job it turned out great!

[@DearHRS]

Great video, just 1 advice try to do atleast 24 frames per second, it will making your stop motion more fluid.

[@illipticaltm6550]

Dear HRS it's not 24 fps 24 fps is way smoother this is what stop motion is supposed to be You idiot 😂

[@devon8419]

That would be way too putsy to take that many pictures

[@DearHRS]

VAGUE PLAYS oh then my bad, I used to watch another channel who used to do stop motion, he said that he has upgraded quality of fps, in 1 video he did 60fps, which was fun to watch and it looked like stop motion.

[@GIGABACHI]

COOLEST shit I seen in the whole day. Make MOAR. It was AWESOME.

[@rexxbailey2764]

IF ONLY EVERYONE WAS TAUGHT SCIENCE THIS WAY IN SCHOOL. ALMOST EVERONE WUD BE A SCIENTIST :-/

[@Sirabadie44]

I believe the counter balance was assembled in the opposite orientation. I assume the weight of the balance would want to face the corner not the side of the rotor. That might smooth up the operation.

[@DoitNXS]

Super cool video. Thanks for taking the time to make it!

[@JarcodeRover]

Wow! Such a nice video! I'm dreaming of this engine in a RC car, a Mazda ofcourse. Big respect for the input in making this video, it should have taken some hours!

[@iguy]

Thank you so much! Hope your dream is done.

[@chikenpaww]

I like aeromodeling and wangkel of course, this video has both

[@TCSC47]

Great video. However, I would say this is a "Wankel" engine, and not include "rotary" in the name. Rotary engines were typically used in WW1 aircraft where the cylinders rotated around the fixed crankshaft rather than what we consider normal nowadays. The Sopwith Camel in particular benefited (if you were a good enough pilot) by using the gyroscopic effect to give a very tight turn in one direction. Upon googling rotary engines I see that Wankel engines have been described as "rotary" by others and not just this utube. I think this is unfortunate because it blots out a lot of the history of IC engines and can be confusing. As an old guy, I have to admit to being mildly irritated by wet behind the ears kids coming along, showing they don't understand the valid history of what they are talking about by misusing terminology in this way. But good video anyway!

[@sirluoslive]

That was neat I'm glad you added the spark anime. Thanks for the video. F.y.i I'm going to build your pop bottle mouse 🐁 trap it's time for a new home buddy.

[@devondaviau]

I love how simple rotary engines are.

[@doktorbimmer]

*Compared to a typical RC engine these are more complicated and have more parts... its one of the reasons they are no longer sold.*

[@doktorbimmer]

*A full-sized automotive Wankel engine like the Mazda Renesis had over 235 moving and seal related parts, many of them very tiny and fragile... a significant disadvantage in both cost, maintenance and reliability.*

[@wph_k958]

doktorbimmer the 13b only has 3 moving parts. The eccentric shaft and 2 rotors I don't think there are 232 seals

[@doktorbimmer]

+Kelan Hume *Obviously you are just speculating... if you had ever seen one apart before you would know it has far more than just 3 moving parts.*

[@vasilipanin8978]

The oil and compression seals never worked except when new, and then not for long. Mostly because they were not rings. Rings last the life time of the engine Wankle seals need replacement like tune up parts. Spark plugs last longer.

[@Prandt100]

Its a legendary Wankel enginne, that was used on Mazda RX 7

[@doktorbimmer]

Rest in peace Wankel engine 1964 - 2012

[@doktorbimmer]

Legendary as a commercial failure... the Wankel never delivered on its promise to revolutionize ICEs and replace them... its a dead-end technology, abandoned and obsolete now.

[@Trumplican]

there are many projects currently using the Wankel design. Your such an idiot bimmer. You dont deserve to use the word doctor in your name even if it is spelled wrong.The Wankel engine is a rotary engine!

[@murat9268]

Wankel engine is lightweight and high torque, but less efficient engine. You can still use them for some applications. It is not commercial failure, it is failed by new stirgent emission standarts. VW is also failed at that test. Diesel engines will be at near future, also normal engines after that. Future will be hybrids and electric cars...

[@Trumplican]

wankels are high horsepower but fairy low torque.

[@joshacollins84]

Interesting video. Thanks for making it. I want one of those engines just to play with.

[@MaxPower-yg1uf]

Many moons ago when i was young i attached a 52" wooden propeller to a 10hp briggs n straton bolted to a table.. after about 5mins of running the propeller flew off the engine at about 6000rpms and blasted my neighbors car as she was backing out of her driveway😲 VERY SCARY!!! We can laugh about it now lol

[@Kameeho]

Amazing video on the rotary engine! Really shows how its inner world's work and all the other parts interraction! I really hope they don't give up on the rotary, if they can just figure out a way to remive is fatal weaknesses, i think it had a big potential as its amazing how small and compact the engine is compared to its power output.

[@doktorbimmer]

*Dude this is a Wankel engine, not a rotary Both the Wankel and the Rotary are obsolete.

[@Trumplican]

Wow and I find yet another comment from the village idiot!!! I gotta make a video on this its just to damn funny! WANKEL IS ROTARY YOU STUPID SHIT!!!!!! oh and if they are obsolete check out Mazda's new prototype!

[@1nkw3ll]

Kubi Kameho Rolls Royce experimented on a diesel 4-rotor several years back (2 rotors to power, 2 to basically supercharge the power), and that might strike your interest. The only real problem the rotary has is due to the burning oil, the seals wear due to constant metal fatigue that most Otto engines don't face so regularly. If there was such a lubricant that wouldn't really ignite but also wouldn't impede ignition, that metal fatigue would go down. Or perhaps a metal that has a higher tolerance for fatigue without absolutely destroying the chamber walls, may also work. Perhaps you could toy with the idea some, I can't think of anything right away.

[@doktorbimmer]

+Dragon *The engine shown in the video is not a Rotary... The Wankel KKM design does not have a Rotary layout.*

[@Trumplican]

Ok either your just saying things to get a rise out of me or you are truly confused. Come on no more mean comments do you need help understanding what a rotary engine is? The original wankel rotary the DKM both the rotor and the housing spun around on separate axes. It reached higher rpm and was naturally balanced but maintenance was complicated and had to be tore down just to change the spark plugs. Now the KKM that Hanns developed was simpler and had a fixed housing but it needed counter balancers to balance the engine and it wasn't capable of such high rpm as the DKM. However it was still a rotary engine. Felix was very angry to find that Hanns built the KKM behind his back and said "You've turned my thorough bred into a plow mare!" He was obviously referring to the much low rpm capabilities of the KKM however still higher that a piston engine was capable of. EDIT: my bad he stated "you have turned my race horse into a plow mare" By the way just a quick google search or wikipedia can help teach you about this stuff why dont you try that?

[@octanedemon5548]

[@martianpolarbeer]

Isn't this Wankel's rotary engine, used once in a Suzuki or Kawasaki bike too, but prone to breakage and very difficult maintenance?

[@doktorbimmer]

*Yes, its a Wankel KKM (the non-rotary version) made by Graupner until they went bankrupt. Graupner, Suzuki ans Kawasaki were all part of the original 26 Wankel KKM licensee's that bought the development rights from NSU (now Audi). All 26 have since abandoned development and production making the Wankel an obsolete design.*

[@doktorbimmer]

+Dandy Lion *Can you point out any comments that were either false or misleading? To my knowledge the Wankel design is in fact no longer manufactured by any legitimate engine manufacturing firm in series mass production. The last company to do so was Mazda who ceased all production over half a decade ago.. Would you disagree with that statement and if so do you have any evidence to back it up? Please provide it, I would love to hear about it. Or are you just in denial of these facts and posting some type of bitter protest from your refusal to accept the truth as it is presented, if so? What is the point of killing the messenger? I didn't kill the Wankel engine... I simply pointed out the obvious fact that it is dead.*

[@dandylion247]

Could you make a clear front plate and record the engine running in slow motion??

[@thaik56]

Where is the ignition coming from? I see no electrical connection.

[@RR67890]

There is No ignition. The plug that he showed is the glow plug. A 1/5 v battery causes the plug coil to heat up. This ignites the fuel, and the heat from the ignition plus catalytic action on the platinum coil keeps the fuel igniting on the compression stroke.

[@deusexaethera]

It's a nitro engine. It runs on methanol and nitromethane, which can be ignited by a combination of compression and a glowing-hot wire.

[@doktorbimmer]

*This is called GLOW IGNITION, the engine has no timed ignition spark and lacks sufficient static or dynamic compression to support auto-ignition as in the Diesel Cycle.*
