Toroidal Non-Reciprocating Internal Combustion Engine

[@jondepinet]

if one wanted a simplified 4 stroke internal combustion engine one need not look farther than the Wankel rotary. and as much as i love that thng, its got its fair share of problems. some of them, particularly the side seals, this monstrosity borrows.

[@ericchapman8956]

@@jondepinet i just dont think engines today are really all that complicated, especially 20-30 year ago. Now, they are complicated in the way their VVT systems and emissions work but a regular old pushrod or overhead cam engine to me is pretty straight forward. I may be wrong but even including the wankel (which i dont have any problems with except durability amd efficiency, i think theyre a novel idea if those issues were addressed) i think we've nearly perfected the combustion engine. I dont see how we would be able to get much more power and efficiency than a 200 hp engine getting 40+ mpg and having a comfortable 200,000+ mile service range (Toyota). I know i sound ignorant, and i love seeing what new technology has to offer, but i think the internal combustion engine is just about perfect. I dont think we will improve all that much in the design department. But i might be wrong, and if i am, i cant wait to see it!

[@barfoom]

@@ericchapman8956 i agree, i think we've reached some kind of endgame with reciprocating engines. on one hand some brands have been experimenting with undersized piston rings to reduce drag at the expense of added oil consumption to keep meeting and exceeding fuel economy and horsepower standards, but thats been biting brands in the ass as far as i can tell. VAGs 2.0 TFSIs did this between 2011 and 2014 iirc. for example. on the other we are still getting some interesting innovations but like you said it seems to be limited to the valvetrain. Fiats MultiAir is an interesting system, as is Koenigseggs freevalve.

[@court2379]

@@ianbuilds7712 Actually gas turbines don't use exotic alloys in the bearings. Those are cooled by oil and therefore don't need to be. The blades in the hot section are where the expensive alloys are used. There would be no issues using a catalytic converter, it would just need to be sized for the flow rate. They are not used in cars because they are less efficient. They also don't have great response times, and would require more complex transmissions due to the high speeds. The would probably be better in an electric hybrid, coupled to a generator. Despite the lower efficiency, they are used in aircraft due to a huge power to weight ratio. As for this design. It would not work, practically. Sealing it would be nearly impossible, if you did manage to enough to get in to run, it would not be for very long. Lubrication is an issue too. Thermal expansion would be uneven causing the seals to open up around the heated sections. The piston would be hard to seal with the walls expanding unevenly. It is a good thought experiment at best.

Hey I suppose he's just looking into an interesting "out-of-the-box" way of approaching a problem. It's far from ideal but it's very interesting. Is'nt that what science is about, asking the questions an seeing what happens, even if it is just theoretical?

[@PKMartin]

@@morgadoapi4431 And if it was described as "far from ideal but an interesting thing to consider" I'd have no problem with it. I'm not saying this engine couldn't work, or that it's a stupid idea, or that you can't improve on reciprocating piston engines. I'm saying this video claims higher thermal efficiency than a reciprocating engine and that claim is definitely totally false. The captions clearly state "higher thermal efficiency" which is totally untrue with no compression stroke, because higher compression == higher thermal efficiency. A generic car diesel engine compresses the mixture 20:1, and that's after a turbocharger increases intake pressure. This design could never achieve that compression ratio.

[@cailco100]

@@PKMartin seem like you missed part of the video. There is a continuous power stroke. The fuel/air mixer is continuously provided and ignited. The valves just close after the position goes through to help keep pressure up. Exhaust gases are exhausted from in front of the position through the ring. You can see it after the fuel and air pipes are added. Watch again and read, don't throw it out the window until you at least understand where he's trying to go. Yes there are more than a few problems. But point to any engine that did at least have some when starting. 4-strokes had poor power to weight. We're heavy, had oil burn that would ask the us to invade and slow. Turbines and jet turbines were unreliable hard to keep going and even hard to make thrust from. Heck steam engines were a mess when they were first invented

[@PKMartin]

@@cailco100 seems like you missed part of my comment. I never said there's no power stroke, I said there is no compression beyond the turbocharger - at no point is the piston moving towards the mixture. The theoretical efficiency of an Otto or Diesel cycle engine is limited by the compression ratio, which for this engine design is much lower than a reciprocating engine so the thermal efficiency will always be worse. en.wikipedia.org/wiki/Thermal_efficiency Saying "petrol engines used to be bad" does not automatically mean this design will become amazing - this engine will always have poor thermal efficiency because of its design, but you need to understand some thermodynamics to appreciate why. It's ingenious and I appreciate the simplicity, but the claim of high thermal efficiency is absolutely wrong.

[@tjdjultima]

@@PKMartin exactly, well said, not sure how many more times Calico wants to get wrecked, but, if all of the valves are evenly spaced and alternate states after a piston travels through them, then there is maximum 2x compression of the current mixture. Even cars that run high boost pressures, like mine, need at least 10-ish:1 compression and spark to ignite pump gas. Also not clear that evacuating the exhaust gasses is efficient at all, the lateral load on the piston seal from centrifugal force would be immense, and it would be pulling a vacuum to get air in so even at 2:1 compression it’s likely barely above atmospheric in practice. Hope this guy got top marks for the animation though it’s pretty slick, but thumbs down for the ridiculous claims.

[@nanstolemybuds]

this is something i was also wondering, once the "valve" closes behind the "piston" the pressure of the air between said valve and piston would decrease not increase, resulting in no compression. or have I missed something all together? an incredibly creative design nevertheless :)

[@farruxbek]

the air is pre-compressed in turbocharger and takes part in combustion as soon as it enters the chamber.

[@agus2001]

Farrukh Sheraliyev doesn't matter, the air loses compression the further it travels away.

[@farruxbek]

I know, but you still thinking of it in an old cliche of reciprocating IC engines. The chamber is already filled with exhaust gases and its under high pressure while piston supplies more fuel and air to increase pressure further in order to continue its movement away from valve until it passes through next valve.

[@nanstolemybuds]

you don't ignite exhaust gases??? you compress the air and introduce a fuel and an an ignition source (spark plug), or in the case of diesels you have intense air compression wich in turn gives you the heat to also ignite the introduces diesel fuel?

[@sMASHsound]

it would have to have labyrinth-like seals like in a turbine or compressor. it could seal. i suspect there would have to be a disc bolted onto the rotor ring, on either sides. so each face of the rotor ring will form a sandwich, with the rotor ring, the toroid body between and the bolted disc.. my main concern is with the spreading/flaring of the gap in the toroid body for the rotor ring. in industrial designs, they would just make it thick enough that it would be very rigid... but i suspect my added bolted disc will help clamp the toroid in..

Awesome. Combine this with continuous burning to generate pressure... and it will work like a turbine. Inject 1 part air into the burn chamber, let the "flame" expand it 1000 times. A small diameter pump "injecting" air into the burner. A large diameter pump using the "exhaust" to rotate the main shaft. It becomes like a "high pressure turbine" or "low RPM turbine. The large radius wheel always has higher torque, to push a small amount of high pressure air into the burner... A high pressure, closed loop, continuous burning engine. Awesome. I found your video after having exactly the same idea as you have - "gates" closing behind the piston, and gates opening in front of the piston. Rotating gates - to keep it simple. Continuous drive, maximum torque, extremely efficient fuel burning, minimal heat loss... You got my support on it, for what that's worth.

Or if even the teeth on the gears wear down some, throwing the timing off.

Maybe there is some other great way to make a combustion engine that is yet to be designed. Coming up with anything is a start and is commendable.

I do not see a phase in your engine where the air is compressed before combustion?

[@WillYouVid]

Lots of people are talking sh*t but I think it's a nice idea, even if it will never become feasible and if it has design flaws like the seal and the friction it'd give out, there's little compression etc. I appreciate that you took the time to design it, you're gonna inspire somebody with your idea that's for sure

[@ahobimo732]

Everyone is criticizing this, but it's an entirely unique and original engine design. Sure, it's complicated, but you have to admire the creativity and intellect required to create something this complex. Personally, I'd love to see an actual working prototype of something like this. Whether it offers any particular advantages over a traditional IC engine or not, it would be cool just to see it working. Mechanical watches don't have many advantages over quartz, but we're still making those!

[@bvogel111]

How would you start this engine, because if the turbo is not spinning when you try to start, how do you get initial compression?

[@VasilyKiryanov]

The same way a piston engine is started - external 'kick'.

[@jubjub905]

A starter that turns the engine

[@nate0031]

A starter can turn the engine, but that is not going to spool the large turbo's needed to make this thing work. Only way I can see to start it is with air. Either you'd need a large tank of compressed air to spool the turbo and start the rotor moving, or a powerful electric supercharger to do the same.

[@lebommjohnson8101]

Lovely cartoons, to be sure ! Got one running yet ? I'll get seriously interested when that happens.

[@pocketchange3543]

How is the fuel compressed to help with combustion? How would you get a tight seal around all the areas in the cylinder walls to keep expansion in the chamber to force the piston around.

Nice thinking out of the box👍 Tip: use 1 gear exchange to a flex shaft to all valves. You remove 33 gears 66 bearings and add one shaft. I bet all your gears sound pretty wicked behind the quick fire exhaust tho😁

[@bryantb3391]

So how does this build compression? Also rotary engine from mazda does the same thing its a 2stroke so its pretty quick but u got mixed gas the piston is a big block of steel and the spark happens by scratching the cylinder they are bad engines that dont last

[@ianbarnard6184]

Talk about moving parts and wear, no lubrication, no rings for compression (lots of losses), heat causes expansion so ur gonna have to plan for that too.

[@whatmakesittick8362]

One simple question: How much money would it cost to engineer and produce these at high volumes? I work with aircraft engine parts (turbine) and regularly visit many aeronautical factories and shops in New England. The tolerances involved in your design in fact require a level of precision beyond the realm of consumer use. The cost of machine work to get the rotational section with pistons sealed against the stator ring would make the basic components of the design too expensive for mass production. The stator ring would also need to be made in two halves, requiring many fasteners around the inner and outer circumference, so that the rotor section could be installed. How would the inner circumference of the stator be secured half-to-half with the need for the rotor between them? Would the pressure of the compressed area between piston and valve when closed exceed the integrity of the gap between both stator halves? In my opinion, the stator halves would need to be quite thick to prevent the gap increasing under load. Or, a robust framework would need to be installed to help keep both halves true and square. Either way, more complexity and more parts required, adding weight and cost. The geared valve timing would also need to go, replaced with shafts, rings and pinions. Or add a timing belt or chain. I really do think this design is impressive and unique. Please don't let me be a damper to your creativity! I'm just telling you from knowing what it takes to actually produce finely machined products, it's very expensive and prohibitive for mass marketing and usually this sort of technology ends up in commercial or military use, which would place your engine design not in competition with car engines or other reciprocating engines, but instead would make your engine design compete against turbines, and let's just say you have about 100 years less experience (and .00001% of the cash flow) than a company like Rolls Royce, General Electric, or Pratt and Whitney. They all are now producing gas turbines with unheard of efficiency and the costs have been reduced by metal 3d printing and other new technologies. Even so, the impressive amount of effort that goes into each one to ensure it doesn't self destruct is eye-opening in my experience. Tolerances are made to exacting specifications and these engines turn thousands of rpm's for hours at a stretch and just cannot fail. Maybe you would be better served using some of what you have created here, some of the principles- and go back to the drawing board, and simplify this idea! Make it foolproof to machine and construct. THEN you're onto something big!

[@Unmannedair]

whatmakesittick this is very well put. I think you nailed a lot of my objections on the head. I'd still be interested in seeing a working version. I can see this as an adjustable efficiency engine by skipping valve closings.

How sealing of air or combustion gas are achieved between the toroid and the rotating wheel?

[@rick57hart]

I see a lot of sealing problems. Maybe it would be easier, to let three little jet engines rotate around a hub. That would give us a nice rotating motor.

[@omepeet2006]

I'm afraid regular jet engines wouldn't last in the configuration you proposed. Maybe it's better to use ramjets instead as they have no moving parts.

[@Totem4285]

Regular Jet engines would work better in this configuration as they do not need to spin at such a high rate to keep thrust and they would be fine with the g-load as many have been developed for aircraft to handle these kinds of stress. The issues with ramjets is they must have an intake air speed of at least mach 1 to be anywhere near thrust producing and even then any engine in this configuration (baring a rocket engine) would be pulling in the exhaust gases of the previous engine into the intake. The exhaust gases in the intake would cause compressor surges in a regular turbine engine and both turbines and ramjets would be starved for oxygen. The thermal efficiency of the ramjet would also be shit because it works on pulling in colder denser air to heat by burning fuel to get the air to expand. Fuel can only heat the air to be so hot and anymore fuel added does not cause an increase in thrust. This is why at higher speeds than about mach 5 ramjets start to shut down. The friction of the air hitting the inlet heats the air above what they can burn fuel to heat it. TLDR: Any jet engine (rocket, turbine, or ramjet) is almost utterly useless in a circle because of practical reasons. Just use the compressor shaft of a regular turbine engine. It makes more than enough horsepower to suit your needs.

[@mickmuzzmkmz1628]

That's similar to the experimental "tip jet" helicopters, which used small ramjets at the rotor blades' tips (hence the name, I know, dir!), in order to do away with the normal associated problem of torque produced by spinning the main rotor mechanically, therefore a tail rotor is no longer required. But I don't know if this configuration has ever been attempted to be used as an engine. Interesting!🤔

[@Wiiplay123]

Or just power the car with a single Tesla turbine. (The inventor, not the car company)

[@farruxbek]

When I made this presentation in 2011 the idea was very raw, unchecked, unproven, without any calculations and computer simulations. Just a hypothesis. But now, when I've finished the 7th version of the engine I could prove all theoretical parts of the problem. The mechanical part is totally different from what is shown here. I could make it even more simpler. The hot part of the engine, that is, engine thermodynamics has been proven by making simulations in ANSYS Fluent. Continuous combustion in a closed chamber with moving piston was too problematic in my early CFD simulations causing backflow of exhaust gases into air inlet ports, but I could solve those problems too. Engine efficiency is at level of modern IC engines. But I think it is possible to achieve better results by making some optimization.

The problem of how to achieve compression is also easily solvable and if you would like some help with the redesign of this innovative concept I am willing to help.

I really like your design. Sure, it won't work as presented, but it is an excellent example of what is needed in a Toroidal design, constant motion, no cat and mouse piston movements and constant leverage. I have referred to this video many times to inspire these three design goals, no other video has so held my attention. I have now completed a design which I believe solves all of the problems I have seen in the numerous Toroidal engines presented on the web. Yours is the video that sold me on the basic toroidal concept. Thank you for your efforts!

pressure opens spring valves into a combustion chamber ahead of the piston. It only needs 2 sections.?

Hey I suppose he's just looking into an interesting "out-of-the-box" way of approaching a problem. It's far from ideal but it's very interesting. Is'nt that what science is about, asking the questions an seeing what happens, even if it is just theoretical?

[@lukebengal1352]

This is extremely clever. I see only a few problems that can be worked around, for example as many people have stated before the lack of a compression stroke and lubrication, as well as pressures and vibration would be very difficult to manage. I propose, and while I realize this would remove the non reciprocal aspect, utilizing the pistons forward momentum to create it’s own compression through velocity. Theoretically, this could allow for greater and greater speeds, given that your cylinder is potentially infinitely long. You could have a compression stroke that lasts for four full rotations if your velocity and durability allow. You could also use this to inject even more fuel air mix into the cylinder prior to the compression. I’d think it would need to start out in a rocking back and forth motion, starting slowly with low compression. So, tackling this issue at a time, I propose this type of operation. Start the piston as a reciprocal, back and forth between two valves. We could control these via solenoid or electromagnetically clutched pulleys for the timing gears. (There’s probably some kind of mechanical way but for ease’s sake let’s use electrical.) The back and forth motion would allow us to build up compression until a threshold where the piston would reach a maximum velocity. At this point we open a valve and let it travel across a longer cylinder. We can then add more fuel/air mix, allowing heavier compression and a longer stroke. Now, for lubrication. What’s stopping us from running oil through the piston itself? Same with cooling, we can bore out the flywheel and run three lines, coolant, oil, and return coolant. For the oil, just use piston rings. Four(ish) rings, two sets on either side. The compression ring, the oil control ring, and two on the other side. Two oil control rings on a single cylinder, allows for no third ring(theoretically). Coolant runs through the piston, oil is controlled, and centrifugal force allows for an easier load on an oil pump. Finally, balancing. With the single piston you’d end up with a ton of vibration and balancing it would be near impossible without use of a counter weight. Simple solution, add a second cylinder at the apoapsis of the flywheel. Since we’re using valves anyway, this could potentially allow for still infinite cylinder length, but also if our valves don’t shift exactly as we need them to there’s no fuel/air wasted. It just preloads the second pistons return stroke more. If this is consistent there’s no issue, and it can be accounted for. In all likelihood, there’s probably a better way to do the valves. And managing exhaust would be a bit challenging, less you wanted to make it a classic four stroke and use the valve “float” (what I’m calling the gap between sealed and open) to vent exhaust gasses. I haven’t thought of a good way to inject fuel, and the best way I’ve thought of a spark plug is mounted in the cylinder head, but again, there’s probably a lot better of ways. Needing to rebuild the whole engine to do your spark plugs seems like a bad plan. Clearly there is much to think about, but there’s my three cents.

[@StompDeni42]

Too much hate by the commenters! No, it wouldn't really work in real life, most likely, but it's a very, very interesting idea and an amazing animation! I really enjoyed watching it. Thank you!

[@TexasHoosier3118]

I had this exact idea 30 years ago. I ran it past an engineer in the physics department and he basically said sealing and no compression

[@johnsmith4630]

I had this exact idea in 2005, the holy grail of a positive displacement piston engine without wasteful reciprocation. came to same conclusions. Cred to the boy for making the nice model. But sealing and friction. Lad doesnt even have compression in it, thinks a turbo could do that.

[@nashthomasson]

there is no compression?

[@fuge74]

the air is compressed, wouldn't need it anyways

[@S50Sinner]

No turbocharger can compress air to the level needed for detonation, the largest and fastest-spinning automotive turbos produce in the whereabouts of 100psi in a one-off diesel drag truck. The most seen in a non-diesel is about 40psi. compression in a modern naturally aspirated engine (about 10:1) provides about 147psi depending on your altitude. Considering that the turbo would have to be feeding air behind the piston for this design, the pressure would be dropping at the same rate that the space between the piston and valve increases. There is no turbocharger that can provide the pressure of a compression stroke, specially not one that can move that much air into an *increasing* chamber. I like when people think outside the box, but when an idea doesn't work, it just doesn't. If you try to develop an impossible design, physics won't just let it slide because everything else about it works and you've put *so much* effort into it.

[@johnsmith4630]

Ricardo yep

[@pja1991]

A pump similar to what is used on a merlin engine would provide more than ample compression but that also adds another layer of complexity and additional seal requirements. It is evident thr engineer put significant thought and effort into this design but I struggle to believe it would pass a simple cost benefit analysis.

[@geoffreykidder5694]

Not even plausible. The gear sets for the valve would fail easily and the valves themselves would be warping each time there is combustion.
