My home made scratch built flame licker - go over

A little video showing you guys my flame licker engine these are also known as vacuum engines atmospheric engines and they all fall under external combustion engines, similar to a stirling engine.
I go over how it works and the problems I ran into while making this. Hopefully it might help someone figure theirs out.

[@nilamotk]

Look on my channel to see the updated video. Converted to run on propane, with the propane stored in the base.

[@robbyberry8911]

Boss you have been through some trial and error price of an education nice job that's what its about I'm mechineing a small engine my self its going to run on propane casting parts my self I know about the price of education do what you love and the fun will follow wonderfull job

[@blackout7615]

I'm curious if you could try a piston ring made from PEEK or Teflon. The type used in automatic transmissions. I'd scarf cut one and try it. I feel you could actually reduce drag between the piston and cylinder. It wouldn't exert force between the piston and cylinder the way traditional rings do. If it could handle the heat which I think if designed at the lower skirt of the piston where heat is lower they would last a long time.

[@nilamotk]

I resorted to using a solid graphite piston and and runs well, but it requires pre heating so that the cylinder expands to operating diameter. The graphite makes a good lubricant as well. I think you would have to machine it tight with teflon rigs as well. Ideally, make the piston and cylinder out of the same material, and in theory they will expand at the same ratio and work at all temperatures.

[@stanleydyer5227]

I'm building a engine myself, Measurements would be very healpful. Stroke, Bore, Etc. Beautiful work making the main bearings and crankshaft. Thanks for video.. Stan

[@malcytull]

Thank you very much for explaining how these engines work, also you are a first class engineer making that from scratch, well done, thanks again.

[@michaeljohnson6473]

The reason every flame licker (even graphite piston ones) engines starts tough is condensation. The sudden heating causes condensation. Try using a heat gun to pre heat every flame licker you ever use. Doing this will extend the life of a graphite powder lubricated engine. This is something they never tell you. I feel it should be somewhere.

[@nilamotk]

Michael Johnson that's not the case with this one. the reason it doesn't turn over o start up is thermal expansion. with the new graphite pistons it must be hot to turn over. and if it's hot condensation is not possible. this engine has been redone since this video has been uploaded. it not runs on propane instead of alcohol. it's alot more predictable.

[@michaeljohnson6473]

Dimple Sharma I am not exactly sure why exactly. But if the engine is cold, or room temp it will get the condensation at first. Once the metal is warm, the condensation goes away, and they run great. You can pre heat with a heat gun, or even a hair dryer. You can also light the burner, move it close to the engine. In about 3 minutes once it is warm to the touch, it's ready to go. Do you have a flame licker? I may make a video demonstrating this.

[@AtlasReburdened]

Michael Johnson Condensation forms because the burning fuel produces a surprising amount of vaporized water. When the burning fuel is sucked in and the walls are cold enough, the gas mixture gets cooled down past it's dew point because it has such a high humidity. It's the same process that forms clouds, fog and dew, except your cylinder wall is the cold morning grass.

[@syedusamamanzoor1838]

thanks a lot bro.... your video was the first one that actually gave some information

[@gwheyduke]

Well done ! Seems to run pretty good

[@bfarm44]

This is where I’m at just starting out making my own designs that I hope will run

[@Skoda130]

Look up "vertical Rebi engine". It's a flame licker, but instead of using a conventional piston, it utilizes bellows instead. Less friction, and just as important, a bigger surface area for the atmosphere to press against. I don;t get it, but somehow these engines are totally overlooked, while they are pretty powerful for what they are. kzbin.info/www/bejne/jWTFeIJuetp_rtU

[@k.i.e1206]

How do you made the pistons, tutorial pls

[@kedarpawar7430]

ur nails tells me how hardworking u r!!!!! inspiring to me...keep the good work!!

[@TalRohan]

thats very cool, I can see why it would be awful to set up right though...I wonder who thought these up originally...thats quite a thought process lol

[@therandomman6647]

You must not have very good aphonespheric pressure where you live

[@nilamotk]

1200' above sea level.

[@leerman22]

I think the piston needs to be fatter and you need more surface area on the exterior to cool better. Perhaps a water jacket or water reservoir on top?

[@nilamotk]

The Eh Team I just machined it to tighter tolerances there's another video on my channel where it's also converted to run on propane, the base is the propane tank. It runs pretty much perfectly now.

[@pocketchange3543]

Nicely done. I would think thinner cooling fins with a larger circumference may help keep it cooler.

[@benjaminandersen1097]

"scratch build".. give us a chance broh, that pretty pro build ;)

[@nikhilbhale79]

I made a similar engine. Saw some KZbin video and surfed the net. Got some basic information and build me an engine. But it doesn't work.

[@nilamotk]

They're insanely finicky. I have a pin of like 10 pistons and valves that didn't work. I ended up making a graphite valve and piston set. That worked best for me. With dissimilar piston and cylinder you need to account for thermal expansion. My engine is completely seized at room temp but runs great at temp. External valve versions are alot more forgiving and run way better

[@danglss76]

Water jacket,something small ,decorative even .

[@boomstick4054]

Maybe not as heavy as this one, but can order a fairly nice one for around a hundred bucks..

[@lillegitimate]

sister: is that dad pulling into the garage? me: no he's in the bathroom on his phone

[@kennymtfh8701]

Weedem BOISSS you stole this off of the vtwin engine video

[@alessandrogest3174]

Weedem BOISSS unoriginal. saw this last vid from someone else

[@NowAndyPlays]

imagine if this was what powered the industrial revolution

[@howardosborne8647]

If it was this that powered the industrial revolution it would never have caught on. The revolution would have been cancelled.

[@joebloe9901]

Great info!..thanks a bunch dude!

[@captainblack2684]

Брат скажи пожалуйста какой ход поршня и диаметр?

[@sasantarom]

Does an ice cold cylinder help ? Is there any thermo ratio? Good work.

[@nilamotk]

Its seized up at room temp. So ice cold would be "more seized"

[@MakinSumthinFromNuthin]

Very nice looking engine, great job :)

[@rogueart7706]

This is really nice. Not from a kit....much respect. You obviously did your research, don't listen to the desk jockey's criticism, you did a fine job. WD-40 IS a lubricant...just put it on some dry metal and feel how slippery it is. Thanks for posting. Thumbs up.

[@MR_R.o.b.o.t.o]

Really AWESOME JOB!! but your flywheels are too heavy. That's why it runs slow. Bit who cares. Your made it work!! You are a engine maker and builder. Great job Sir!

[@FredMiller]

New subscriber.. I have great respect for scratch builders. Since I retired I have made a number of model steam engines also all scratch built. Keep up the good work and drop in on my channel and take a look around, Regards Fred Ontario, NY

[@nilamotk]

Fred Miller thanks Fred I appreciate it. I'll definitely check out your Channel

[@UrgenthelpwithSubscriptionsHel]

Shut up 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

[@bensons999]

This looks cool, what is it? Flame licker engine eh? Made from scratch? Nice... *WUNG!* *WUNG!!!? I love you! Marry me!* _(Wait, you ARE a girl, arent't you?.. WUNG!.. Never mind, I don't care anymore)_

[@nilamotk]

I'd make a for a pretty ugly young lady.. 🤷‍♂️

[@MATECH-ds3vw]

i don't no what's your piston size but you try 22.00 mm the piston size. and polish cylinder 00.03mm

[@nilamotk]

entertainment the engine runs perfectly now I just changed the fuel type to propane and it solved all of my issues

[@howardosborne8647]

The weak performance of this particular piston valve design is caused mainly by the limited valve opening duration available and the inability to set the valve timing with any useful 'advance' of the power piston stroke. Flamelicker engines with the valve timing dictated by a separate eccentric cam and rocker arm give far better performance than this design. I have built one of these piston valve engines to very similar design from plans supplied by Jan Ridders and also I have built a Beng's 'Nick' flamelicker. The Beng's engine operates the valve by means of a cam with adjustable advance on the valve timing. It runs far superior to this piston valve design.

[@nilamotk]

Thats good Info, thanks but I will never have a patience to build another lol I'm on to mini river jet boats with too much horsepower recently. Lol

[@jakenbaked87]

holy shit thats impressive

[@kriseckhardt5148]

Ta wung it!

[@adam_-adam]

i want to order one of these on ebay, but would like to know if this thing at least has enough power to where if i put my finger on the flywheel lightly that it wont stop, was hoping it has at least a timy bit of power to it, like just a little more than what it takes to just spin the flywheel, any feed back would be appreciated

[@nilamotk]

adam a couldnt tell you that. I dont own the one from ebay, I built this one from scratch. Some flame lickers have some tourque but its all depends..

[@spencerblackburn7670]

Your pro

[@captainblack2684]

Бро, скажи пожалуйста, какой ход поршня и диаметр?

[@FoodCollectionGD]

อยากซื้อครับ ขายเท่าไรครับ

[@danbreyfogle8486]

This is a very nice looking engine. I enjoy seeing them run slow as it is possible to see all the parts in operation instead of them being a blur.

[@tyfitzpatrick3606]

Try using a valve with less mass... A significant amount of your power is going into moving your valve piston back and forth...

[@nilamotk]

If I ever mess with it again I might try this. But for now it's just a paperweight in my display case.

[@cottonperez339]

very nice work thanks for all the information.

[@MagnetOnlyMotors]

Excellent machine work, like the sleeve valve, great stuff, Bud!

which gas u used bro?can i use also kerosen or butane or candle?

[@nilamotk]

Markwesly Depena in the video its alcohol. Its been converted to propane tho. Theres a video on my channel.

[@DonovanBryant92]

i would use a weed eater piston and head to build a home made engine

[@nilamotk]

Donovan Bryant then half of its not home made ;)

BY THE WAY WD-40 IS NOT OIL

[@nilamotk]

I'm well aware, it's a water displacement agent.

[@daviddouglas4200]

Hi, can i suggest you look at two stroke oil ( as used for two stroke engines, mix with petrol ) this is a lubricant designed to be burnt & is low ash. Its very thin as well !

Cool i learnd a lot :-)
