Also using an expansion chamber to let the liquid form to a gas fully before being expelled will help a lot with efficiency. Having the cartridge pointing downwards as you have it empties all of the liquid before it has a chance to turn into a usable gas

[@Mitz500]

[@jluvs2ride]

Or orient the cartridge with the outlet up.

[@ondradanek45]

I think that even just changing the thin rubber band for something like a gt2 belt would massively improve the performance. And also if you would use some kind of pressure regulation, spreading the CO2 discharge over a longer period of time (just a small hole the gas has to go through could be enough), it would also help

[@dusterthefirst]

I second the pressure regulation. The co2 cartridge is super high pressure and most of that is going to waste out the exhaust. Using something simple like a capillary tube (I think) could help regulate the pressure leaving the cartridge, meaning that the engine can convert more of the pressure to rotation.

[@Flare-nd]

i agree. He should 3d print a belt using bendy filament and make a belt pulley system. The engine has a lot of power bu the power is being lost due to the rubber band slipping out

[@Nworthholf]

It just needs a receiver of 2x the size of the bottle

@@integza you were losing a lot of power using the rubberband. the way it is bouncing around and not sticking to the axil. also recommend making the exhaust of the little vehicle point to the rear so you can use the rest of the power loss to help propel the car.

[@rainerandkatieniederoest825]

Is a regulator or gears would also reduce the waste.

[@Nominale_]

Also, seal the engine a bit better, and use a pressure regulator so you don’t waste so much CO2 making it more efficient (and not detonating the gears in the engine) With a pressure regulator you’ll be able to run the larger CO2 canisters without worrying about the pressure blowing up the engine

[@pseudotasuki]

And it can limit the torque to a usable level.

[@pseudotasuki]

Rather than just spinning the pulley on the engine.

[@FicusThreeSixty]

a better wheel and belt could be in order as the wheels and belt where slipping a lot.

[@potatosalad68]

Actually pressurized liquid can be better... maybe?... Just think about water rockets. They are more powerful than compressed air rockets.

[@DeuxisWasTaken]

@@potatosalad68 Sadly not. This works for rockets since increasing the mass of the exhaust gives more thrust, but here we don't care about the thrust produced by the exhaust and we're basically wasting liquid gas that would otherwise decompress still in the cartridge and give more power.

[@potatosalad68]

@@DeuxisWasTaken Oh, I meant it for the modified rocket car version, when he unplugged the wankel motor.

[@evilbrewer]

Also a pressure regulator or at least a decompression/expension chamber would go a long way for the wankel motor I think

[@cnc-maker]

Aside from needing a regulator to lower the output pressure, you also need to make sure that the neck of the cartridge is facing upwards. The cartridges are filled with liquid CO2, so you are expelling the liquid and not the gas. Turning them upright will give you more thrust and better control.

[@michaelseitz8938]

And maybe heat up the cartridge? Releasing the CO2 may cool down the cartridge so much that the CO2 remains liquid at ambient pressure? Or maybe not, these cartridges are fairly small ...

[@cnc-maker]

@@michaelseitz8938 the faster the gas is released, the colder the cartridge becomes, and the lower the internal pressure becomes. However, that is not entirely what causes a pressure drop. It takes time for the liquid to turn into gas, which is usually the most significant reason for the pressure drop. When you use a regulator, you extend the length of time that it takes for the cylinder to evacuate, which in turn gives the liquid more time to turn into a gas. Heating the cylinder will help the reaction somewhat, but typically not by enough to make a difference. If you're looking for a 5-10% difference, then heating the cartridge might be what you need. Good thought though!

[@christopherhauck4702]

yes "inetzga" can't seem to understand the wasted energy of liquid co2 coming out of the exhaust port he even knows liquid propane makes more flames than gas if he flips the bottle so why is he no noticing the same flaw in reverse with the co2 cartridges?

[@christopherhauck4702]

@@michaelseitz8938 nope 90% of performance issues is just the fact he has the pop side down rather than up while in a gravity field with a critical gas canister flip it and he'd get more stable and longer running 800psi flow with less issue caused by rapid loss of liquid co2 mass sure mild warming if he intends on using 800psi for very long might be needed in smaller cans but at about the 88-90g cans the depressurization of his projects at max flow won't be enough to chill anything bigger than a 16g can enough to lose performance plus he seemingly can get lots of propane which is a nice source of a stable phase change 150psi source so he could use propane bottles to run "pneumatic" engines on the go with much cheaper valves plus the flames from the exhaust ignited by "integzabot" would be a nice cosmetic touch

[@keagancunha8244]

Hey, some suggestions, use a small gear coming off the wankle's axle and a larger gear on the wheel's axel would be a better transfer of power. Also the exhaust from the motor could be redirected to help push the RC car. Also, reducing the the diameter of the pipe before the CO2 goes into the motor will let the motor run longer and put less stress on it

[@MrScorpnok]

Ooh maybe integza could try to make a pressure regulator himself, its basically just a spring that presses against the incoming gas - and a screw that squeezes the spring more firmly against the oncoming flow, thus making it adjustable - OH or he could try something whacky but fun and make a governor, used in steam engines - as a person who works with modern automation ive always been fascinated by governors

[@DeTNTonator]

You're using co2 wrong. Instead of feeding liquid gas that expands inside you have to let it expand before feeding velocity based engine. You may try redoing it with proper atomization onto heat radiator to speed up evaporation, or use it with more traditional piston engine which performance should be good on lower rpm with proper dozing. For the evaporation on liquid co2 i know there was airsoft gbb with very small gas useage that used cylindrical mesh which dispensed aerosolized liquid co2 inside small metal chamber before feeding. There was practically no visible fog coming out of it with preserved bb velocity compared to other types, and significantly reduced gas useage. You can basically apply similar rule to combustion engine... trying to add too much fuel will choke it and supress it's performance, or even cease it's operation. Basically do not try to hit highest rpm in first try, but make it work, then improve. I really want to see it explo... Eghem... work. And tomatoes are great!

[@SSingh-nr8qz]

Yes, exactly! That was what i was screaming at the screen while watching this. Most of the fuel is lost just getting the car rolling.

[@benholroyd5221]

Agreed, should stop the engine destroying itself every 5 minutes aswell

[@SuicideNeil]

That's what I've been thinking the whole time- he needs a way to control the flow rather than just dumping it all out at once. Expansion chamber and regulator set up is a must, and a gear-reduction unit for the actual drive from the engine to the wheels. This project has great potential, just needs a bit more development...

[@AJose-xj2tj]

Maybe a spool valve with a LPR to regulate/expand the CO2 to a gas. Add a point to the rotor to trigger the solenoid at the correct time. Maybe even some logic with the deadtime of the solenoid and everything like a ECU would handle.

[@jeffreylakey8052]

I think the CO 2 cartridge you are using is enough power. What I think you need after the valve is a pressure regulator. The pressure regulator will allow you to throttle the engine, And allow you to preserve psi while cruising but alow For higher psi out put, for climbing hills.

[@kabeerphulwaney]

Having a slow controlled valve, releasing the pressure gradually and having longer operational time would be great, also if you also point the wankel exhaust behind the car it’d improve the efficiency because that pressure from top adds huge pressure on chasis and unnecessary friction.

[@ricardojahns4348]

he also could print a few more chamber getting more power (making a bigger car, adding a trailor for additional weight??),and the fuel would be spread instead of going only to rpm. Also on other channels I saw that it makes the motor more calm, because vibrations compensate each other. Also I think from turbo freaks to add an expansion chamber (actually it is not liquid CO2, but solid), could be usefull to get more use from the fuel

[@kabeerphulwaney]

@@ricardojahns4348 another great idea 👍🏻👍🏻

[@bdeimen]

Friction is part of it, but additionally it looks like there's so much flex in the axle/chassis that the periodic jet from the engine is causing it to bounce and lose traction and the rubber band is too flexible for the amount of energy being transferred, so a ton of the energy is getting lost to wheels spinning in the air, rubber band flex, etc. I definitely think a slower, more controlled gas release would go a long way to solving the issues. It would give it a longer operational time, but it would also help bring the forces down to tolerances that the materials involved could actually handle.

[@independentpolicy3247]

Toothed belts to prevent drivetrain slip, tighter tolerances in the rotor and better seals on the apices of the rotor would greatly increases the torque and decreases blow-by in the engine. Add in some lubricant to fully seal the engine and he may have something a bit better for the application.

[@bigwendigo2253]

Not only that, but it looked like the belt going from the engine to the axel was slipping a lot, so printing a toothed belt or a chain would prevent that from happening as well

[@S85B50Engine]

Wait… what? Every production RX-7 I know of was a twin-rotor. There were three-rotor engines built for the Eunos Cosmo… and I suppose now with a bit more Googling, it seems like a few people have done a motor swap to put three-rotor engines into some RX-7s. But in this specific scenario, I don’t really see how using more rotors would solve any problems. Integza wasn’t facing any issues with vibrations really, but rather faced issues with the fact that the wankel rotor-by design-rotates three times as fast as the drive shaft. Multiple rotors help in increasing available horsepower/torque to the drive shaft at more and more offset intervals, but this often comes at the cost of much more complicated eccentric shaft designs (in order to enable assembly), while the rotational design itself already reduces vibrations significantly just from not being a reciprocating action. Adding more rotors to a compressed-air wankel probably also wouldn’t really make any sense, as it would just increase the static volume of the system and thus decrease the pressure of the system as a whole leading to less power… and as mentioned, still doesn’t solve the design principle that a Wankel rotor rotates at a speed 3 times that of the drive shaft.

[@JohnDoe-fk6id]

You need to turn the CO2 cartridge right side up, so that the outlet is at the top of the cartridge. The reason you're getting "snow" is that the liquid CO2 in the cartridge is being allowed out the bottom, instead of requiring it to boil, and releasing gas out of the top. You will get MUCH longer run times, if you do this. Adding a regulator would help, too.

[@cheerdiver]

No completely correct, dry ice is sublimated from the drop in vapor pressure. Though he can GREATLY increase the eff by adding heat on the secondary (ie loop) side of the pneumatic motor. The expansion of gas by a heat exchanger can be seen in early steam engine designs. Wonder if he's considered moving a liquid on the secondary side. Gravity may help reduce the sublimation, yet it's decompressing too fast.

[@JohnDoe-fk6id]

@@cheerdiver not quite accurate. The co2 is stored in the cartridge, under pressure, in liquid form. When the liquid is dumped out the bottom, it is no longer pressurized to the point that it can remain liquid. As the liquid instantly boils, the temperature drops low enough that SOME of the liquid solidifies, leaving "snow" of dry ice. This solid co2 doesn't contribute anything to the production of power. If the gas is taken off the top, then the solidification takes place inside the cartridge, and as heat is absorbed into the cartridge, the solid will sublimate, leading to continued gas production.

I printed this motor up and ran it and I’d suggest using just a drop of air tool oil in it. Doing so made it run so much smoother than with just graphite alone. I supplied it with 125psi off my shop compressor and the bypass tube on the side blew out. If you can add a bit more thickness in that spot I think it would handle it. It also has a balance issue that could be remedied with a flywheel. I would lengthen the shaft and have it protrude both ends of the engine and put a balancing wheel on the back and a drive gear on the output. All in all its a pretty good start.

Could have just said the degree of limitation upon the valve opening should work as a regulator without having to take the money for a real regulator. Correct me if im wrong but a valve half open releases half the air flow as compared to a fully opened valve.

Hey Joel: The slow-mo footage shows that you are gettimg a lot of slippage in the rubber band drive. This is likely due to the extreme rpm of the Wankle engine. Many model train engines use to use rubber band drives, so this type of drive can handle a lot of torque. I would first install a needle type throttle valve in the system, which would lower the pressure that the engine is seeing, and make the gas charge last longer. I would also consider either using "O" rings in place of the rubber bands, or go to a gear drive. The "O" rings are less stretchy and stronger than rubber bands, which reduces slip, but a geared drive has no slip. Cheers!

combust... air?

[@benjaminshields9421]

This system already does run on air with one of the simplest valves in existence

[@agentbarron3945]

what do you mean by combustion engine that runs on air without complicated valves? this could easily run on compressed air (co2 carts just have a bit more psi they can put out than most air compressors) or if you mean a literal combustion engine thats 3d printed, its gonna have as complex valves as a carbonated engine, as well, its gonna be one, and even then theres no way it could be 100% 3d printed

video idea: design and 3D print a .... 3D PRINTER! (using of course the components of a real 3D printer, logic board, head, etc.) but not the frame, gears and pulleys! The challenge is, once everything is printed, make a sample print (previously printed with a real printer 3D) and see the level of detail between the two!

Please do some metal 3D printing projects! There are FDM filaments you can print that are 80% steel and 20% plastic. You can put it in a kiln and the plastic burns away, and it sinters into fully metal parts. Check out Ultrafuse stainless steel 316L for example.

Integza, for the wheels, possible stronger rubber bands, or a tensioner pulley, and possible switch the drive to a rear wheel setup. (You could switch your intake and exhaust port connections around)

If you used a gearbox or a chain drive you could get a lot more power. The rubber band is slipping off the axle. 3D printed gearbox would be a neat addition to this.

Video idea: Try to understand the new Veritasium video about the wind powered vehicle the goes faster than the wind. I really want to properly understand the fenomena as it is still a bit confusing

[@hohenheimnokia4595]

I understand it like that, not sure though : Initially, the cart with propellers on is accelerated by the wind to the wind speed. In this process, the rotation of the wheels also cause the propellers to rotate. However, we were to compare the cart with another one of the same mass but not propeller, the cart with propellers takes longer to reach wind speed. There is therefore more energy in making the cart with propellers to moving to the same speed. This extra energy is stored in the propellers' rotation. When the cart reaches wind speed, it is no longer accelerated by the wind. Assuming here, that the wheels can rotate the propellers and the propellers cannot rotate the wind, the propellers now push air backwards. This further propels the cart forward. The propellers can be modelled as a spring which gains energy as the cart reaches wind speed. After that, it returns the energy to the cart increasing its kinetic energy. The cart thus can move faster than the speed of the wind for a short time period.

[@JamesManukonga]

Could you use this setup on a 'liquid piston' engine? They seem pretty promising, would be cool

That video my warped perception was complete garbage. That engine wasn't even running it was connected to an electric motor making it spin. Those guys are wasting time and money the engine will never come to fruition.

[@tomkay2907]

@@chillaxter13 Exactly my thought

[@bogdanungureanu8655]

Very cool idea. As a further project, I personally would try to install the engine in a rear engine layout and do so flat on its "face". You would conical gears to transfer the power to the wheels (which may be not a good idea considering the engine goes from 0 to full power in milliseconds), but it would theoretically be an improvement over the belt, and by not having the vehicle wobble up and down due to the rotor, the traction would be much better.

You could add an orifice after the valve to limit flow consistently and make it last longer. Plus maintain grip on the drive pulley to accelerate more efficiently.

[@fuzziau5669]

Definitely needs some structural stability, some silicon sealant in any seams of the engine, maybe also add a mini regulator for the valve too so you can control its output force. It obviously is just proof of concept but I feel like it’s such a beautiful and crazy design that should have a true representation of its ability. Even if it has a lot of vibration that mostly cannot be controlled, and a shape that is otherwise not that efficient on its own.

for the throttle you can regulate the air that comes out of the exhaust, by doing it that way you always have full power but the engine spins slower.

You actually can 3D print a whole drone, as it's potentially a cheaper (and quick) solution compared to buying the skeletal frame and casing for the DIY quadcopter to name one - some are ridiculously expensive. So 3D printer is obviously the answer for certain quadcopter builds. Not to mention the advantage of optimizing the center of gravity related to the weight of the avionics put onto the drone frame, ensuring it do its job well in the sky without falling straight down.
