Thanks. Yes its a vacuum engine. The valve is simply connected to the piston with a rod that can freely move up and down through the piston. When the piston is almost at the top position the valve closes, the air cools and moves the piston downwards and keeps the valve closed until the piston ist almost at his lowest position.
Thanks. Its so hard to get flamelickers running because they are very unefficient (only about 3%). In my projects building flame lickers took less time then getting them to run.
This is VERY useful to me, since it shows how valve assembly can be very simple. This could fit on a tin can type of engine, and this brought me a step closer to just that. Like using a metal jar lid on the bottom of a tin can.. So sliding construction.
That's a *very smart design* and an awesome model! C.A.D. and C.N.C. machines have allowed for so much creative freedom. Awesome project you've got there. 2:44 I wouldn't stand there though!
Latheman666 Sorry, I got this engine confused with the one I watched beforehand. Another guy built an electric rotary motor and I meant for the comment to go on his video. My apologies. That is one very cool and creative model engine you've made there!
Very good engine and different. Actually I not known this model, but I could not understand the workings of the engine! He works as an engine vacuum? Greetings from Brazil, Leandro Wagner.
Just found your video, fantastic bit of model engineering. Congratulations on a unique and great running flame licker! Would you consider publishing plans for your engine?
Nice flame eater. If you put a small set of magnets and coils you could build a really cool battery charger for small batteries as i'm sure there is not much torque but may be enough to provide some mA or charging. Very cool
Congratulations !!! very interesting project two years ago I've tried something similar to this valve - but couldn't achieve perfect axial alignment for the valve and refused the project.:-( Now I see : this type of valve is possible. Thanks
Latheman666 Gotcha very efficient design after I build one that will work, I have set my sights on this model just for the unique design, and i have parts very similar at my disposal what appears simple often is not, I was thinking of turning down an engine valve, what do you think.
Hi, I just found your site, it's great! Ever thought of making a 2 or even a 3 phase flame licker motor? The exhaust stack on this video gave me the idea. After all it's really a hot air motor so like a 3 stage steam engine, this should work too. I'll get on it right away as soon as I finish my elbow engine. :)
Very nice engine! It runs smoothly. Thanks for sharing. However I do not understand the valve system. Can you send me a drawing of the operation? Regards, Douwe
+Marcel Shaffer Exactly :). The real power comes from the flywheel momentum *pulling the piston and flame in, then the valve seals as the fire extinguishes, and that depletion of oxygen results in a vacuum which pulls the piston back*. It's just like the "upside down cup with a candle in it" trick you may have seen, where it will suck in water as the candle dies and uses oxygen. *Literally "pulling" the piston instead of pushing like a gasoline would, pretty cool shit!*
Can you tell me where I can see kinematic connection between the piston and the valve. For me this project is very curious and would like to know more about it. Thanks in advance!
hmmm... valve and piston driven/driving crank, possibly a bit of play and spring on the valve itself so it seats properly, with a disc sliding on the valve stem acting as a one way valve inside the cylinder. and it needs to hang upside down not only to meet the flame nicely but also keep the valve closed...
Latheman666 I thought about that (as generally any solid or liquid expands when heated; in this case the cylinder). Thank you for a nice, sarcasm-free reply & explanation =)
+Brandon Veracka The problem is not the cylinder expanding, rather the air does not cool down in the closed space that much if the surroundings are warmer. This type of engine depends on air cooling and "sucking in" the piston.
{MLP} Rainbow Dash I think it's more a case of the metal heating-up from the inside (and thus swelling) that makes these motors start to slow-down so quickly, but I could be wrong. A fan might help a little, but the problem will still remain.
I think there’s a easier way to make a flame-licker engine. Increase the stroke of the piston, and install a ball-bearing check valve. You could also make a upside down funnel which is mounted in front of the air intake. So if you put the machine next to a campfire, more heat would be directed to the engine. And if you’re going to use a campfire, the diameter of the piston could be three inches. That would drive a larger generator. This machine could also be mounted on the side of a cast iron stove. It’s much simpler than a Sterling engine.
theyre utterly useless, a gimmick. the only power you have is the pressure of the atmosphere acting on the back of the piston, against whatever pressure the cooling gases of combustion reach... and as atmospheric pressure is only 14.7 psi, and you are very unlikely to get even half an atmosphere in the cylinder... you have barely any force on the piston. the larger the piston the better... the colder you can keep that cylinder, the better. yet at a certain size, the volume of gas being cooled exceeds the ability of the surface area to absorb it. they may be simple but they are obnoxiously finnicky and can barely run. 99.9% of the heat goes "up the chimney". a stirling is far superior... and even they suck. sadly the next progression, adding valves and pumping air through external heat exchangers with far better surface area to volume ratios with subsequent better heat transfer, seems to have been forgotten about. ericsson cycle, amongst others... which led to the development of the turbine engine... same idea but with no valves and the combustion fed into the working "cylinder", said cylinder driving the compressor, consuming a certain amount of power, and whats left over appears as "work". which as a piston based design by cayley, the "furnace gas engine"... was subject to valve failure for obvious reasons... it was 1850 or so, they didnt have stainless steels or inconels or other fancy metals... or machine tools. it had to deal with raw flame and ash of a furnace... they had the theory behind a turbine, they didnt have the materials until the 30s... with a single double-acting piston, and one cam operated valve, its pretty simple. replace "furnace" with "heat exchanger in fireplace". ericsson cycle. then you get into diesel cycles, akroyd hot bulbs... at which point "hot air engines" got left behind in the chase for more power which is dead simple now we focussed entirely on one architecture... burning the fuel with the air inside the working cylinder... steam? too complex, too dangerous, too inefficient. no matter what... 80% of the energy goes to waste, it simply cant be improved... water has a massive amount of energy held in its phase change from liquid to gas... constantly being boiled then condensed is the killer... pump the heat in... then dump it out, taking the cream off the top... you cant recover that heat, that energy. you cant use the heat of condensing water to boil water... as the temperatures get closer, theres less transfer. once the waters condensed, that energy is too "diffuse" to be of any use other than to slightly warm more water... never boil. takes six times more energy to boil water than it does to take it from ambient to boiling... the advantage of the stirling with the regenerator is how that "latent heat" is stored in the regenerator between cycles, and the majority of the "cream" alone is used, that bit of extra heat added and removed in the two stages. air only having a low thermal mass, and no phase change. at that point its limits are volume to surface area, pressures, density, and mechanical efficiency. its worth pointing out that you still lose half the heat out the chimney. you cant heat the hot end higher than the exhaust gas, and when the exhaust is half the combustion temperature, the maximum energy at the highest potential is being transferred. can heat MORE stuff to a lower temperature, can heat LESS stuff to a higher temperature, but halfway is the goldilocks zone... we ALMOST have the same thing in a fridge, its just the reverse cycle... pump the heat in to get power out. the stirling uses heat as it flows THROUGH it, a flame licker holds its hands in front of a bonfire...
I think it's the hot air escaping and allowing the cylinder to cool which draws the piston back in and allows the cycle to repeat so it would be counterproductive. I think. Don't quote this ;)
Fun engine! I have searched google for the plans, and your video comes up in a million different URLs - but no plans! Could you private message me the plans? I would like to make it
+BenAranMetroidkiller I don't know this particular design of vacuum engine, but usually if vacuum engine is adjusted corectly, it can run a DC motor and generate some electricity for sure. This one seems to be too slow/weak
I wanna have that fun. I wanna a flame gulping engine for about 3 years now... I don't belive i'm able to do any, and i could not find anyone selling one yet on my country...

@@paradiselost9946 I got it, but the part I don’t quite understand is the ‘cooling’ of the air when the valve is closed. It’s only a second or two. Couldn’t be much cooling. Thanks
@@johnr5252 thats the issue... have to keep the cylinder cool. gets worse as size increases. not much surface area either. and as theres still air in there, its doesnt really have much drop in pressure... unlike steam... its a VERY inefficient "atmospheric" engine. which only have 14.7psi of atmospheric pressure producing force to start with...
Syed Usama Manzoor it is a flame licker engine the engine sucks in the flame and then seals off the chamber that air cools and contracts sucking the Piston back in, then the cycle repeats
I turned attention that The concept of "previous" everyone uses 1/4 the power that offers the principle of action ... but will soon get everyone to understand what is missed
This could be refitted with a mechanical relay using solar power to run store and place dynamo generator to spin for redundancy feed back. If ONLY. Peltier teg could use heat to light a led up from excess heat absorption. Alternatively a parabolic mirror with a Fresnel lens could sterling drive effect this in another way just potentially not cost effective.
Great it looks,,but not one connected to a pump or generator because like stirling motors they only produce enough power to keep themselves running ,,no extra,,and that makes them useless,,,
This machine might be more efficient if the heat source were turned off as soon as the valve starts to close, and only opened just before the valve reopens.
That valve design is the simplest and yet the best I've seen so far
Thanks. Yes its a vacuum engine. The valve is simply connected to the piston with a rod that can freely move up and down through the piston. When the piston is almost at the top position the valve closes, the air cools and moves the piston downwards and keeps the valve closed until the piston ist almost at his lowest position.
The balance of this engine is exquisite. Beautiful work Latheman!
Poppet valve integrated with the piston.....good job Latheman, Can't get get much simpler!
or more inefficient. but less parts breakage too. Im ambivalent.
this is awesome! could imagine a like 7 cylinder radial like this, it would look so crazy running
superfunnyman123
but very hard to run

Great work! I like the weighted flywheel - it adds to the unique look of this engine. Thanks for the MIM reference. I'm going to look it up.

Greetings from Brazil,

thats a pretty dangerous bong
The ultimate SHTF fan. Awesome! Very Amishy.
So are you not showing the crank and rod side while it’s running on purpose? Would like to see how the valve mechanism works.
But can it run a load? Like a belt or gear mechanism?
Probably, with enough fuel
TheBikerScout the engines usually have like 0.001 hp :D probebly not
Nope. It barely has enough hp and torque to keep itself running
I'm legitimately wondering if the RPM of this machine would be higher if you would mix up some weed in the fuel source.
+thaGkillah What a waste. Both of weed, and of your time thinking up this dumb idea.
now you're thinking like a stoner, it just smokes it for you! automatic hot-boxing machine!
no no no .that's a puffer motor from jamaica man.
Why are people so triggered? He was just joking!
hahahahahahaha

Congratulations !!! very interesting project
two years ago I've tried something similar to this valve - but couldn't achieve perfect axial alignment for the valve and refused the project.:-(
Now I see : this type of valve is possible.
Thanks
Really nice work. Hats off to you sir!
I like how it's purposely unbalanced, well done
is that a flywheel or are you just happy to see me
FANTASTIC, very much like a piece of art,No ?? I Like it, now there is a second piston in is there not???
Only one piston inside. The thing that is moving outside is the valve.
Latheman666 Gotcha very efficient design after I build one that will work, I have set my sights on this model just for the unique design, and i have parts very similar at my disposal what appears simple often is not, I was thinking of turning down an engine valve, what do you think.

at 70 rpm.

Does it have vtec?
put a fire torch on the valve this thing will go crazy mad hahaha
Nice, what kind of efficiency are we talking about if we try to harvest some energy from the crank ?
majonesn Extremely low (
Latheman666 Kinda like an uncle spinny dervish?
wait... so does it make a vacuum... or what?
+Marcel Shaffer Exactly :). The real power comes from the flywheel momentum *pulling the piston and flame in, then the valve seals as the fire extinguishes, and that depletion of oxygen results in a vacuum which pulls the piston back*.
It's just like the "upside down cup with a candle in it" trick you may have seen, where it will suck in water as the candle dies and uses oxygen. *Literally "pulling" the piston instead of pushing like a gasoline would, pretty cool shit!*

Can you tell me where I can see kinematic connection between the piston and the valve. For me this project is very curious and would like to know more about it. Thanks in advance!
Supergut gebaut !
Can you tell me who made this? Incredible flame eater.
It seems like it comes down to the manipulation of air pressure by temperature gradients.
Reimu Hakurei you are correct
el aire frio entra sin impulso?????
Am I imagining think or it's getting stronger and stronger?
Hong An Nguyen it is slowly speeding up
Whats the working principle? Air expanding due to heat and pushing the piston out then cooling down and sucking the piston back in?
Pau Gasolina the engine sucks in the flame and then seals off the chamber the air cools sucking the Piston back in then the cycle repeats
Hi there , I'm about to make my first flame eater , can you give me an idea of the tolerances required between piston to cylinder .... Thanks
I can't say it in numbers, but the friction should be kept as low as possible, even at the price of tightness.
hmmm... valve and piston driven/driving crank, possibly a bit of play and spring on the valve itself so it seats properly, with a disc sliding on the valve stem acting as a one way valve inside the cylinder.
and it needs to hang upside down not only to meet the flame nicely but also keep the valve closed...
Quick question: Why does the engine slow down after it begins to heat-up, despite still having the flame going at the same rate?
+Brandon Veracka The efficieny depends on the difference of temperature. And it decreases as the cylinder heats up.
Latheman666 I thought about that (as generally any solid or liquid expands when heated; in this case the cylinder). Thank you for a nice, sarcasm-free reply & explanation =)
+Brandon Veracka
The problem is not the cylinder expanding, rather the air does not cool down in the closed space that much if the surroundings are warmer. This type of engine depends on air cooling and "sucking in" the piston.
+Latheman666 what if you added a small fan to the shaft? Could it then maybe run a little bit faster?
{MLP} Rainbow Dash I think it's more a case of the metal heating-up from the inside (and thus swelling) that makes these motors start to slow-down so quickly, but I could be wrong. A fan might help a little, but the problem will still remain.
How is power transmitted? I am only seeing the connecting rod to the valve, and am curious how this particular model operates
Oh, I see. The valve is connected directly to the piston via a spring, correct?
Could this run on sunshine. The side of a shed in direct suns gets incredibly hot.
+John Smith Not really, you need hot air to rush in the chamber. There are Stirling engines that run on sun shine.

Now add a turbocharger
Is there any way to prevent the hot air from escaping?
I think it's the hot air escaping and allowing the cylinder to cool which draws the piston back in and allows the cycle to repeat so it would be counterproductive. I think. Don't quote this ;)
DANGEROUS DAVE
K thnx
and what if the whole piston part was in an airtight chamber to suck the flames in with greater efficiency
What are the bore and stroke?
Que máquina linda.Genial . Parabéns 👏👏👏👍🙏🇧🇷
is the piston bigger than the valve? i want to build a flamelicker with a valve like this.
No. It is even a little bit smaller because the valve opens and closes the end of the cylinder in which the piston is running,
what material is the piston? how have xou made it?
Tobias Karas Please read the description of the video and get a copy of the model making magazine that I name there.
thank you for the information. i haven't seen the description until yet.
What is the pipe on top of the cylinder for?
water cooling... they have to keep the cylinder cold or they dont work... colder the better. and as theyre always sucking a flame IN...
Fun engine! I have searched google for the plans, and your video comes up in a million different URLs - but no plans! Could you private message me the plans? I would like to make it
have you tried hooking up a DC motor as a generator to it? Judging by its performance, its probably capable of driving 10-30 watts
nope it would probably struggle to light up a single 20mw LED

i like these toys
it seems very simple to buld
This machine might be more efficient if the heat source were turned off as soon as the valve starts to close, and only opened just before the valve reopens.
+Quientin Wadman Or another valve starts to open when this valve start to close.
