'The main problem I was running into a lot, was just sealing this rotor' - every rotary engine owner ever
Apex seal goes BRAAAP BRAAAP BRAPP BOOM
when norton created their version of the wankel rotary, they listed the seals as a service item and had a sort of two stroke oil injection.
this was a very good engine, as soon as the seals started to wear. funnily enough, the new seals performed poorly until they became 'worn'.
Don't forget to put some 2 stroke oil in the gas 😂😂
Dump some pencil lead into the gas tank.
The Apex of the issue lol
Video Idea: You should design, print, and make a fully 3D Printed drone! The challenge will be to make it as light as possible but at the same time sturdy and stable in the air.
Tomatoes are disgusting!
this would be cool
@@mikevandebunt811 Yes, you are right but the challenge will be making it yourself; different from these models!
@@alessnespoli but Integza usually does things that HAVEN'T been done with 3D printing before.
@@mikevandebunt811 I agree but I think it would be very cool plus if you think about it, also the Wankel Rotary Engine 3D Printed isn't something new as he said at 1:13
Hi Alessandro! Congratulations you won a 3D Printer! Send me your info (Name, Address, Zip Code, Phone Number) to integza@gmail.com.
The reason why it's working better with the inlet angle changed is because you're effectively running it as a turbine. You should try just switching to an efficient turbine.
This is exactly what I was thinking the entire video.
@@Aybman if using the co2 again you may try your original small bore adapter as it seemed alot of the energy could not get transferred so was wasted
13:58 I love that Snape is right next to Tesla in the background.
Now 3d print the rest of the Mazda
Also, my apocalypse skill is kidnapping Integza so that he can do everything for me
hahahaha 3d printed compressed air powered mazda
Damn stole my video idea. Enjoy your 3d printer
I want a 3D printed 787b
You already have a 3d printer don't you.
ah yes Integza is now your personnel creator! jk :P
Integza: I hate tomatoes
TH-cam: we know, here’s an add for Hienz Ketchup.
Not to worry, ketchup is made from 100% brutally murdered tomatoes. They are skinned alive and then boiled, can you imagine that?
i like drinking dead tomato bodies mixed with sweet things and other ketchup ingredients
lol
Sus
Hmm... a pneumatic wankel blender
I really enjoy your channel. What a cool thing you've put together. There are a lot of maker channels, but not many are as entertaining as yours! Thank you for everything you're doing!
Love this! Great work. Just want to point out though after watching the slow motion with the acrylic cover, the current position of the compression stage bypass allows the compressed air to also escape past the piston and out the exhaust in the second half of the cylinder rotation. Have a watch of the piston movement in slow motion. From what I can see you're only really getting drive from the point the air enters the cylinder to the point where the cylinder tip reaches the start of the bypass. Maybe a 4 tip piston or adjusting the position and size of the bypass would solve this. But this is an awesome project and congrats on the success so far! Keep up the great work!!
Video Idea: 3D print other types of engines with similar displacement and test their horsepower for a certain PSI
Edit: or just banana power
Congrats
Ur winning dude
Yes! Although, not horsepower.... bananapower!
@@BRUXXUS Hahaha yeah good idea
@@BRUXXUS and rate every engine in rotten tomatoes score later
You should use the motor to make a tomato-grinder
I came here to suggest a rotary powered blender with various tomato assassins falling to their death
Nah I'd try with something that require more rpm capability than torque, that's the peculiarity of the wankel
FUxckyeah
or just like the viral 2018 trend of shredders
Great work! Rotary engines are some of my favorites! I’m intrigued by the functionality of such a small, but complex engine. If I had to suggest anything, maybe see if it could move a bicycle using regulated co2 canisters which release periodically to conserve pressure. It would probably have to be put on a horsepower ratio for more torque, but that part should be straightforward. Keep it up!
Yea he said easy engine... Not so much tho
First time I've watched you. Brilliant!!! I don't think I've heartily laughed watching a maker video before. I really, really enjoyed your skills and presentation style of skills. Thanks. Oh, and I learned a LOT! Doesn't get much better than that.
I think the video idea is obvious you should collab with Tom Stanton and make a mini helicopter using this design and your brains
Plane, Plane, Plane, Plane,
Yes
Why should they put their brains in a mini helicopter? It's not very practical, a person's brain should stay inside their skull
I personally don't want to see Integza's brains.
They might be made of banana....
I’ve been a car enthusiast for a while, and it made me really happy to see you use graphite on the apexes. In most of not all rotary engines the apex seals are actually graphite.
ahh, the infamous apex seals. I have been trying to get into the rotary car scene but I have to save up to get that car.
Save up plus 3000 bucks ,apex seals are fun 😂
@@sbeve9820 they make newer apex seals which last a lot longer, different material
@@sbeve9820 they should be made from tungsten carbide, would last much longer, but the price would be well higher as well.
Harder materials left "chatter marks" in the interior wall. Mazda engineers called them "the devils fingernail marks" - I have to imagine tungsten carbide would fall into that category.
You should create a puzzle box that solves itself when you blow air into a tube or use an air compressor. It could be like a rubiks cube idea in simple terms that when air is added it spins back to a solution or certain pattern. I think this is an awesome idea and would love to see it come to life in the future on your channel!
I think it would be cool if you made a remote-controlled plane using one of these engines. Obviously those little CO2 cartridges and that bicycle pump (almost the same one I have actually) probably wouldn't be enough to make it fly very far though.
"The air gets exhausted, because it did soo much work " you've gained a subscriber
That was a very natural add placement for solideorks. I loved that.
I thought that was the sponsor until skill shared came up later
Very cool. You managed to copy nearly every single characteristic, even the reliability!
You got my subscription with the "shut up" line and the banana bit lol
Everyone else: Don’t Try This At Home
Integza: You can’t try this at home? I will give you a 3D printer.
"Don't try this at home, unless it's in the attic"
haha that's a genius way of taking this xDxD just for the honour of your hands: just dont build burning/exploding things xD integza's sacrifice is enought xDxD let's keep watching this tomato do funny stuff like that in his attic :P xDxD
@@JannisDesigns he moved house and no longer has to use the attic
The BALLS OF STEEL having a propeller spin that close to your hand
I think directing exhaust of decompressing CO2 onto your hand is more of a problem here.
I was actually thinking that 1 half of the propeller will eject once the centripetal force was sufficient. good thing it didnt. dont want them to get hurt
@8A Benaiah Dandel you
And A
Integza, you are one of my favorite makers. I enjoy your failures as much as your successes. You have a fantastic attitude towards failure. You cannot succeed without failure and we fail to learn
I was looking for such a film about a rotary air engine. Thanks for this movie.
I actually really like the graphite as the apex seals. That’s a nice touch.
Just like the real deal
I'd make it spring-loaded on top
@@The_Wack I thought the real deal used spring loaded steel pins?
@@bagochips834 they used graphite as an apex seals on the older model like rx1 & rx3 I think while the rx7 are usually made of metal, and are pushed against the housing by springs.
Will it not wear down fast?
I'd love to see this develop with a two rotor design like in the Mazda 13b
Or a 4 rotor
@@nickrusso5058 like a 787b?
Dorito boys
I've watched several of your videos now. Good stuff man! I can't explain why, but this is the one that convinced me to subscribe. ;)
Hey the low temperature came from the co2 when the gaseous form of co2 gets compressed it creates dry ice and you can see the tiny pieces of dry ice in the time stamp 12:59 to 13:04 thankyou love your videos.
There’s lots of ads for Skill Share out there, but “your survival in the apocalypse is contingent on how useful you are” is the best one.
this is the only dude that can get me to watch an ad and enjoy it
I agree 😂
I also agree!
@U w U it’s just a personal thing from everyone ig lol
I think 3b printing a strandbeest and powering it one of your 3b printed compressed air engines would be really dope to see!
You could create a RC plane that's powered using cardridges and the Wankel engine from this video. Would be really nice to see something like that! Or you could use this Wankel engine to propell a RC boat!
You should send a few of these to Tom Stanton and let him make a compressed air quadcopter with his bottle setup. Challenge him to lift a banana.
Tomato
I agree it would be great to couple this with a feeder mechanism lightweight enough to fit into a copter or plane.
Yeah, or just send the files...
The air gets exhausted, because it did so much work. I love it!
Check out the "liquid Piston" engine. It swaps the rotor and stator shapes giving three chambers (three expansion points per revolution) and a long blowdown period (high efficiency). It would work on compressed air just as the Wankel does.
Have you considered making a basic dyno for these engines. Could be as simple as coupling a small DC motor to the test engine and placing a resistive load across the motor terminals. By measuring the voltage and current produced you can calculate the power output of the test engine. Graph this against engine rpm and add a correction factor to accommodate for the rotational losses of the DC motor generator and you'll have a pretty accurate way of measuring each test engines performance.
Make the “integza engine” come up with your own idea for an engine whether it’s combustion or whatever and make a miniature version of it
i have a feeling ur gonna get a 3D printer
Bruh lemme get one too
@@Chris-eb6id lemme hold one
"haha just invent a new type of engine" wtf is wrong with you? Are you brain damaged?
@@beastlymace2214 someone else has already won but I will be commenting this on the next video since I was kinda late to this video so look out for the comment when the video comes out😉😂
so it is 1 banana power engine
Not to be *that guy* but since 1hp is equivalent to lifting weight in m/s if your "weight" was one banana I'd imagine the engine powered with co2 could output several BananaPower™️
And we all know bananas are radioactive, so it's basically a nuclear engine!
I’d say this engine is at least a 10BananaPower (10BP) engine
How much Llamathrust is that? 🦙
This is not an engine. The power is coming from the pressurized air!
You may want to put parchment paper (wax paper) down before you print parts. I believe it will handle the heat and let the parts separate easily.
You could have just put in a rubber seal around the drive shaft.
Put some saran wrap around the drive shaft then put a rubber compound around the lid.
Just like an intake manifold runner length and some other stuff on a naturally aspirated rotary engine greatly effects the total power and powerband
“After that the air gets exhausted, bc it did so much work”
Best joke ever
“If things go according to plan”
The integza equivalent of “what could possibly go wrong” 😂
@Macho Sancho he is a good TH-camr
I worked on a job years ago where there was an Amish trim carpenter and he had a modified DeWalt miter saw that was converted to run on air. It sounded like a motor from an air powered impact gun, without the impact sound. It worked okay but the RPMs were lower than the electric version. He had a gas powered air compressor outside that ran it. He hired someone to modify the saw. It looked mostly like a normal saw except that had a connector for an air hose coming out of the motor cover.
I’m fascinated as if you can build a engine like this powerful enough and strong enough to power a car
Using graphite "pencil rods" is very brilliant !!!
The only issue is that graphite is porous
as a car guy, i love you for making this, us JDM boys love rotaries
True
*Y E S*
Lol I love rotaries and suggested the idea on an earlier vid but ig he never saw it cause I didn’t get a shoutout😢
DORITOS FOREVER!
Not when the Apex seal broke😂
The concept was very well demonstrated , thanks
Your videos got me back into "hobbying"(?) again! love it!
I can't imagine what would happen if you and Tom Stanton would collab: it'd be a mix of english neatness with mediterranean chaotic talent: I'm hoping it'll happen some time in the next future!
Video Idea: "Make multiple Triangular engines and stick them together (with some kind of camshaft) to power a vehicle, and they put that vehicle through a series of tests (Offroad, Acceleration, Maenuverability etc. etc.)"
He should use it on his boat
Put a pressure valve on the engine it's really cool can't wait to see more
A very small adjustable pressure regulator if its going to be used in an air craft design or a union capable of installing washers with different size holes in order to restrict air flow.
imagine the power you could get with two triangular rotors that counter-rotate to cancel out vibrations...
Make a helicopter XD
Idea: you should make an air driven car using this engine and compete with Tom Stanton !
Yes a rc car with this engine would sound great.
It has to drive for more than 20 sec without a compressor
try using a big bottle for it to hold compressed air so when u stop pumping air it use the compressed air in the big bottle u can 3d prin the connector from big bottle to ur engine
Since I love this type of engine I would love to see it with more rotors.
I'd recommend to connect it to a flywheel, since the movement wasn't that smooth, and after that, you could try to hook it up to a little generator
use high-pressure air instead because it will not solidify when exiting the tank
And the generator is hooked up to a compressor, which will then power another Wankel engine
@@der.Schtefan Or could it power itself ?!?!? (I think it is not possible?)
Video idea: contact your friend Tom STANTON to use your engine in one of his projects, or if not possible just make a tomato shredder ⚙️🍅⚙️ 😁
i would suggest that exhaust to be saved and pushed on a piston, also needs an idea to reduce noise and vibrations. for noise and vibration I guess bigger case with some rubber or vinyl coating the application, which will get us into weight problem!
Look into the Liquid Piston Rotary Engine. It is somewhat similar to a Wankel but it tends to use a rounded surface, for the contact area between the rotor and the casing, instead of vertex seals.
There are a variety of alternative engine designs out there which are, increasingly, amenable to 3D printing in polymer for testing / proof-of-concept work. Naturally, if you can get a plastic version of the engine working with compressed air, you have a basic design which may be amenable to building and using with internal combustion.
Look into the Quasiturbine, as well. The inventor on that was talking about using it, for forklifts, etc. running on compressed air. You really don't want those using internal combustion, since they tend to run indoors.
I'm really hoping that the ice you're seeing from using the CO2 cartridge is water ice. When you release the pressure in the CO2 cartridge, the pressure drop causes the temperature to fall. This will condense humidity out of the air and, if the temperature is low enough, freeze that condensation. If you were actually handling dry ice with your hands, you'd likely end up with burns to your skin.
Edit: well, shoot. I just saw your liquid piston engine video. You beat me to it. I only discovered your channel a couple weeks ago and I'm still catching up on your videos.
Do a race where all your builded engines race against the others an look who`s your strongest/fastest engine
Make a 5-speed transmission for the engine controlled by a servo. You could make a series out of something like building a small car with every component per video.
Well, you have a high speed pressure to rotary converter. It can be regulated by controlling flow and pressure. Time to make a food chopper. You could also use this concept to make a fully pneumatic lathe controlled with stepper motor valves and an Arduino.
For more power you could mirror your intake and exhaust on the other side instead of linking and wasting those chambers and that would give you an extra power stroke every rotation
I like how it's easy to forget that Integza is an extremely talented and smart engineer.
is he?
@@remiclaeys9136 are you?
@@sufferr2914 i think i am
@@remiclaeys9136 good for you
Now I wanna see a Three stage rotary engine, that's probably like a 100xtimes banana strength.
Have you seen rob dahm's 3 and 4 rotor? Absolutely nuts lol
Edit: spelling
If you continue with the co2 carriages with this system you should make a plane that utilizes the extreme exhaust pressure as propulsion.
Or you could have a version that uses compressed air in a bottle but also has two extra co2 cartridges for boosts while flying s and also have the entire thing remote controlled
Yeah, I was wondering if that exhaust velocity could be used for something. Just pointing it out the back of an aircraft would be interesting. If it was a fixed-wing prop plane, probably the exhaust velocity would make the plane outrun the prop. But if it was a rotor-wing providing the lift, and the exhaust providing the propulsion... hmm...
You should attatch a second rotor in order to use the output gas of the first rotor as power source, since it seems to have a lot of cinetic energy.
I wasn't expecting much from this as I'd understood that Wankel engines were very sensitive to tolerances at the seal but using the graphite pieces was just inspired and the engine really worked very well. Impressive.
There's a story, probably apocryphal, that Wankel intended to use the recently "discovered" ceramic silicon nitride seals because it's highly heat resistant and can be made extremely hard and smooth, a perfect bearing material for engines (where it's used a lot today). However, at the time it was only made in the USA and was considered a "strategic material" because of its military applications so no US maker was allowed to sell it to foreign companies. Hence Wankel had to use inferior materials that meant the seals had to be replaced too often to make the engine commercially viable despite several carmakers giving it a try.
Since Integza's engine runs cold, graphite was indeed an inspired choice.
For your next video, make a dual turbo fan rocket 3d printed. It creates lots of pressure and uses liquid fuel, so those would be your 2 main issues
Wankelmotor is a fourstroke-motor. You can drill holes on one half or make two intlets and outlets.
An internal combustion engine has 4 phases; intake, compression, ignition, exhaust. An air pressure engine uses just two; expansion, exhaust.
If I'm not mistaken you could set up an airpowered rotary to have double the "powerstrokes" of a combustion rotary, aka 6 per revolution
When the project works the first time:
Something's wrong, I can feel it.
Imma only say one thing: *WANKEL ENGINE POWERED BANANA TREBUCHET*
no wait. tomato trebuchet to send the disgusting tomatoes flying through the air and smashing into the ground!
Slow down, I can only get so turned on~
You should make a "giant" rc car with it powering it, maybe even putting multiple of them together (2/3/4-rotor). But would have to put a mini air compressor inside as well
remote-controlled rotary-powered drag racer.
This is amazing btw
Yes! That would be so cool
There's an inverted design: oval inside, triangle housing that mostly solves the apex sealing issue by bypassing it. Maybe give that a try as well?
I just Googled that. There's a company called LiquidPiston who has funding from DARPA. It looks very interesting.
@@JonS sick aye, warped perception made a slowmo vid with a clear cover on the engine.

Integza, you should try to make tomatoes useful (in a disgusting way) and make a biofuel, then use that in a liquid rocket motor (or something else, it’s up to you)
yes
Lmao yes
This is a hard one: Print a gearbox and lift your car with the rotary engine
Lets get this comment to the top
he'd need to use metal parts which he cant manufacture or very heavy duty plastic parts that are expensive. either way, it probably wouldn't make for a profitable video, so i don't think he'll do it. also that engine has barely any torque, so the inertia and friction of a gearbox with that large of a ratio would probably instantly stall it. not saying it can't be done, just saying he'll probably fail/not try.
If you’re on the highway, you have a constant pressure. If you use a funnel you could possible increase this pressure. It won’t push the motor much because of the law of thermodynamics which means it will always go slower than the car’s engine if under the same load. This could, however, recycle some of the energy not being used currently and especially at high speeds. It’s more environmentally friendly, but I highly doubt that it would be cost effective.
you can make a teeny teeny teeny tiny inlet for the cartridge to last and maintain stable rpm
build a compressed air cannon that will launch tomato’s to their doom
Tomatoes

I think that the most incredible thing you could do with a 3D printer, would be something that you can either communicate with another person somewhere else, or creating contact from one island/continent to another island or continent
I reckon you could make something that flew subsonic.
Just an idea, if someone is thinking about using this or something similar to build a compressed air airplane, I would make a 2 rotor either counter rotating with 2 shafts inside each other with 2 props or 2 180° offset rotors on one shaft. This helps with vibrations. Also if you use 2 shafts you can solv the roll problem a fast engine like this causes with props.
Day five of telling integza to 3d print a resin shell for the ceramic vortex cooled engine to prevent leaking
I've told him an sent him links to 2hr fire proof drywall mud an it doesn't harden like other mud it's kinda rubbery.
BANANAAA! Awesome video Integza and thanks for the shoutout. Looking forward to see what you do with it next
Hi!
The CO2 gas expanding is an Endothermic reaction (It absorbes heat) which is why it gets cold enough to freeze solid.
Having the CO2 container submerged in warm water to provide some of the heat will help it maintain a little higher pressure for longer.
since the air your letting out stil has allot of preasure, meaaning you could attatch maybe anothe engine to it and even one more to that one to get even more power
or connect a few scuba tanks and see if you can power a smal kayak by air
You should get a cnc machine like a shapeoko. Being able to work with aluminum and large pieces of plastic would be really cool. They are also cheap enough to be easy accessible.
And get a lathe and a mill
Sounds like it's time to collab with Tom Stanton to turn your engine into a viable RC plane.
I wonder if u could make some sort of RC car with this? Maybe one powered by a controllable compressed air kind of like the PC duster cans but with a controllable valve on an rc car, or on a large scale you could even use a paintball gun air tank for some huge over powered rc truck
You should harness the exhaust pressure if using it on a toy car by placing the engine in such away that the exhaust pressure points backwards for some extra energy
Idea: Make a compressed air powered plane with the Wankel engine and check how much time it could stay flying.
Jet engine is better
When I was a kid, Air Hogz had an airplane that ran off of compressed air. You would pump it up using a bike pump, spin the propeller to start it and then throw in and it would fly until it exhausted the compressed air. It sounds very similar to this project. You should totally make your own, maybe even make it run on the co2.
