Dude, this is absolutely awesome! Not enough of the younger generation is interested in creating their own projects and building something like this. you did a phenomenal job man!
+Steven Meyer Thank you!
I used to daydream about doing this kind of thing, when I was your age (I am guessing you are somewhere in your teens). I didn't have the wherewithal, or skill. It's really cool that you worked out how to do all of this, and that you're obviously excited about it (I can hear it in your voice). Keep learning, and keep doing what excites you. And don't be afraid to move on when things have run their course. You probably don't care too much about what other people think, or you'd never have got to this point, but in any case, you'll encounter various naysayers who don't get the whole "journey of discovery" thing. Just ignore them. In order to learn, you have to re-trace old footsteps. At the same time, realize this is just a beginning.
P.S. I'm seriously amazed that a simple rubber o-ring will seal that piston and not melt in short order. Also amazed you can get anything like 5000 RPM. You're probably getting a better seal with that than the metal rings you see in a typical engine. "Blowby" is real, and "positive crankcase pressure" will pump oil right out of a typical engine.
+Brandon Lewis I'm 20 so just short of being a teen now! But I was 19 when I first got the engine working. Thank you! I'll keep it up!
I'm also surprised the o-rings hold up as well as they do. As long as you keep them happy with a little oil now and again they last a long time and do give great compression.
that lubricant dropper thing looks amazing !
+JellyfishJelly Thanks! It's just some pennies, cut up glass vials, and a aquarium air valve.
You said it all in those three word, ".....this is awesome." This is so far beyond home tinkering because you are doing the math calculations along the way. Great work. I like your ventilation system. It is a critical add if you are running this indoors. Good news about the new o rings holding up.
+Lidmotor LOL I guess that's one way to put it! Add a little math and now it's beyond tinkering! I never liked the term tinkering for some reason. I never refer to what I do as tinkering. I just don't like the word for some reason. Yeah the ventional helps keep the fire alarm from going off! :P
You have made your own IC engine with considerable power?! Wow, i thought your steam engine was great, but this is super crazy cool! Most people wouldn't even understand such motor, constructing it is impossible for 99.99% of people in the world... I mysel love all engines, but I was just able to put few stirlings together... Nice work man, keep it up.
+Bizzon666 Thank you! Yeah not many people have build IC engines let alone without a machine shop! Not many have even heard of Stirling engines before so it's pretty awesome that you've made some!
Well done, I watched all your videos making this engine. Very impressive.
This is kind of thing they should be teaching in high schools. A lot of the school metal and wood shop projects seem to be stuck in the past.
Absolutely amazing, you have a design of your own, crude but refine it and improve one step at a time. Seriously keep it up this astonishing!
It looks like the engine is generating about 0.02 hp. Very cool mini homemade engine made of scrap parts! Congratulations!
+Wayne Ashby nooo! Probably more because of the inefficiency of the generator! :D
+Makerj101
Good point, the horsepower at the direct output of the engine would more. I was calculating based on the 15 Watts at the final load end. Hmm, I wonder how much it is at the engine output? I wonder if there's a way to determine that easily.
+Wayne Ashby yeah I know! I've calculated it that way before as well! Easiest way would be to build a prony brake. Using the prony brake you could measure the torque. Then use a tachometer to measure rpm and then use those two values to get true shaft horsepower.
Makerj101
Sure, a Prony brake and tachometer could be used to derive the "brake" horsepower.
this is probably the best video I have watched on the Internet so far.
dude keep up the good work, i have no idea on how to build one and im 23. you keep up the good work and u will definitely succeed in life. you definitely blew my mind building this!
man you are so brilliant! i love to see how you make it work !! you must be very balanced to make things this way, i have no words for it ..bravo !!
Torque permitting, it looks like the efficiency of this system can be greatly increased by making your own rotor/stator setup, using the shaft directly instead of a belt (main benefit being that you're able to use stronger neodymium magnets (in acrylic wheels, for example), as well as wind your own massive generator coils). I don't know about internal combustion engine design to have any comments on that, but a positive side of this setup- if kept- is that the current bottleneck that is your stepper motor, can be replaced. (maybe even a multiplier gearbox setup can be used to get more power out of the same setup, again, torque permitting)
i think when you make it a 2 at 1 ratio to the alternator you loose less power on the crank shaft
Good stuff young man. You are smarter than your years. Keep it up. Can't wait for your next project. I'll be watching.
amazing!!! Good job! I love how not only do you build this, you also do the castings!!! #subscribed
The majority of Sterling (temperature differential) engines are made w/o machining - out of 'junk'. If you hadn't heard about the Sterling, a large variety of heat sources can be used. Solar, almost anything that burns, or redirected exhaust from, say, a furnace. Your enthusiasm and persistence are _admirable_! Keep going!
great design. amazing you built without needing a machine shop!
great job on the whole project, bravo!
Well done dude, amazing build and videos about it, learned alot and was fun to watch
+suicidal.banana Thank you!
This whole series was great. Thank you
Little engine that could.. Great job you did there , thank you for sharing.. amazing work .
Kudos to you, thanks for showing this productive creativity and an informative explanation!!!!!
I work a lot with small model car gas engines and i'm impressed! Awesome!
nice! double wall cylinder or at least a water jacket, old diesels used evaporating water quite often. very cool build!
Nice job! It actually runs pretty smoothly!
Very neat project! I would have loved to do a project like this when I was in school. Now I work on engines that are rated in megawatts but they still operate on the same principles.
Congrats, man. It works great!
outstanding !!!! also loved your fridge compressor engine both are very cool !!
Your absolutely brilliant bud. great job. now I want to make one
Well done ! What you've built is incredible. You've got talent and brains young man. Follow your bliss !! Life is short, and goes by so fast ! and the older you get...the faster it seems to go....so, live life to it's fullest !!
hey there young fella..amazing project there you accomplished..you got a good mind..id be proud to know you ..keep up the work i see a great future for you
Wow.... just absolutely incredible.....budding mechanical engineer in the making. PA has great engineering universities and they already have a spot for you. :)
+David W Thank you! Hahaha I hope so!
This is what UA-cam should be. A bunch of people sharing their random projects and how to videos.
I'm sure this kid isn't a kid anymore by now but, HELL YEAH KID!!!
i really do admire you're projects man. Im only 17 and im currently making a 3 1/2 guage steam train in my shed . i was inspired by youre origional steam engine so i worked extra and bought a small metal lathe and now i can make anything ! if you ever want any help thinking up project i can always help out and i mean youre quite the engineer so it would be interesting too compare some ideas. keep it up man
What a great project! nice job on everything! I wish I could've seen the video of the carburetor being built, and the assembly of the cooling system.
+SkaggnettiAnd TheRejects I will eventually have videos on all that stuff. I shouldn't have posted the video out of order...
Inspirational! Keep Rollin' !
Magical，I have a very high regard for your works
Two stroke engines are lubricated using the fuel+two stroke oil mix of about 20to1 using the metric system which we use in the uk which varies on manufacturers recommendation as that is a two stroke engine that system would be sufficient, good job.
Also that cold fuel is helping to cool your cylinder with every fresh charge.
bravo sir, i've been thinking about building my own engine for a while now and never actually did it because machine shop and such. i might have a go at this :)
+WheelH0rseC101 Cool! I think you should give it a try! I really want to see more internal combustion engines made without a machine shop! There really are not many. Best!
One word, that's really awesome!
+Green Silver Thanks!
+Green Silver 5 words total.
I am amazed that the soldered joints don't melt and make it all fly apart. Beats the heck out of all Sterling engines I ever made.
You made an engine? AWESOME!
+Gio Penguin I have a whole series of videos showing how I made it.
This is an excellent project; so many facets of science and technology to explore as refinements are made, and you've got metrics to help you figure out what works and what doesn't.
On its efficiency: In addition to fuel, other energy sources that the engine is using to run ought to be accounted for, else your numbers will be misleading. This includes the power required for the spark plug, and the power used to circulate oil and coolant. Cheers!
+Nevin Williams Thank you! Yeah you are right. There is some power used for the ignition. But it's not a lot. I will eventually use a magneto or something so that the engine is fully self running. I could just hook the HV circuit I have up to an inverter and run it off the battery... That would be the simple method hahaha There is no power used for coolant or oil yet... But I hope to add those soon.
dude you made my day if i had a lathe i would send it to you and make your day so anyone out there that has something you could donate to this kid do so hes all of our future and makes me proud im sure your folks are too good luck and motor on
+ric torres thank you dude! That means a lot to me :)
Wow that is one of the best selfmade engine you are the best
Totally awesome dude... I'm speechless...
I feel like I've been waiting for ever to see this!!!
+Kyle Coulson Hahaha only a couple of weeks! :P
+Makerj101 I know I just like catching your channel. You gotta make more vids more often ;) lol. cool shit man keep it up!! I always wanna try and make some stuff like this and then I watch your vids and I'm like.. Sheit I don't have any of this equipment lol.
+Kyle Coulson Thank you! IDK that's hard with school an all. About 2 videos per week is about the most I can really do unless I leave out all editing and go with a more technical v-log type style. LOL I don't have that much equipment! There's lots I don't have! I'd love to have a lathe... those things are big though.
+Makerj101 make more vids and you can buy a lathe with UA-cam money!! ;p lol
+Kyle Coulson IDK I'll think about it. I like the style of video I do now but I'm always up to try something new. Wood lathes are cool. I prefer metal lathes though. It would take a couple months of UA-cam earnings but I could do it. Prob would be where to put it. Since I will have to move out soon.
love this...you gotta do an updated video with the fixes you made..aka the check valve and how you built the oiler and carburetor. please lol
+Erik Weishaar Yeah i need to get the other part edited and posted
Really impressive!! What your getting here is real world experience at the physics, mechanics of these machines and all the complex engines you may encounter are just bells and whistles for efficiency or performance in one area or another!, so I say awesome young man!!! Very creative!!
Im suspicious your engine is delivering more than 15 watts. A thought,, maybe you know this as I haven't watched many of your videos but with a small DC motor you can connect it to a another DC motor and drive it as a generator. Shaft to shaft,,just some tape will work. This will allow you to load test it as all these small motors peak out as it were at generating. Short circuit the motor you are driving with an ammeter and a voltmeter and you can watch the current and voltage rise as you increase the speed of the driving motor. It will peak out and you'll know what the driven motor is capable of. All the best,, I'll be watching!!
Ya know it took me awhile to figure out your oiling and cooling method. The bicycle inner tube stretched around the cylinder and filled with water is so simple. It worked for these short runs. Boiling water stays a certain temperature. Simple science. Brilliant application. Using two pennies for the oiling chamber ends. Amazing.
+Lidmotor Exactly! It works great! I'm working on upgrading the cooling system right now! I think I'm going to make it super complicated with a water pump and everything! Yeah pennies were just the right size!
+Makerj101 try using a radiator pump and tank. like how you would cool a hot cpu.
+DoomedWalker_ That's not a bad idea. Problem is I would have to buy those since I don't have any water cooling stuff. I think I am actually going to make a radiator out of copper tubing. Sorta like this: i220.photobucket.com/albums/dd96/tcg001/b77d1b52.jpg Either that or chop down an AC coil.
+Makerj101 I have 3 aio water coolers lol.
+Makerj101 and that's just what have that's not in use lol.
Yes, I really enjoyed. Wonderful, young man. JB Weld FTW..
congratulation to you.
nicely done BIG thumbs up for that !
Thanks for doing this I just love it !!
very nice work. thanks for sharing. greetings from germany
make your ignition timed
it gives the engine more power
+robot797 I'm not sure about that. I will eventually get an ignition coil and test that but the constant ignition seems to give quit good results. How would it give more power?
becaus it burns the fuel bevore it has full compression
when the ignition is timed it fires only at the right compression
i dont know exactly were that is
but i do know that my rc car ran crap on my homemade cdi unit (continius arc)
and great on a timed arc
+robot797 Ah ok. It could have some improvement. I'll have to invest in an ignition coil and give it a try. So far out of all the ignition methods I have tried the continuous arc worked the best.
+Makerj101 if the piston is in the compression stroke and it fires before the piston is at the proper point ( slightly before top dead Center) than the piston has to fight the expanding gasses and you lose power and i know in a vehicle to advanced timing can cause serious damage to the motor
+Makerj101 Ignition timing is very important in ICEs. Because the mixture takes time to burn, the spark should ignite the mixture a few degrees before top dead center. Generally it's about 10 degrees advance, but it depends on the engine and various factors. Too much advance and the gas will reach maximum pressure before top dead center. Too little and the pressure will "follow" the piston, so not full power is transfered. Fun to play with for sure :)
I tried bubbling fuel before but as the gas cools it evaporates less so your heating water use a small pump and run the hot water through a coil in your gas to heat it your engine will be more efficient Brilliant work good job!!!! or if you want the water to boil instead of a pump look up how an old school coffee maker works you could percolate water through the coil in the gas to heat it.
absolutely amazing ..you built that from scratch ..new sub...
well done lad,, just watched the compressor video i have to say i love your videos i really want to make at thest a compressor jobby
You're a VERY bright kid, seriously.
I would call that by no stretch of the imagination a success
+JamesT Yeah, a slight success! :D
Dude, you are amazeballs.
This is basically how they figured out how to make a car. This is awesome
That's great, good work.
nice really fun and cool to watch!!!
Since you now have a working design you can experiment with other kinds of cylinders, i'd suggest trying to cast aluminum right on the copper cylinder tube with the ports and cooling fins all made in the styrofoam, this way you could even incorporate proper mounts for the cylinder.Good luck exploramenting !
+John Johnson That's an interesting idea. I think I may go with water cooling on this engine. Just because I like to make everything extra complicated! XD But maybe I'll try making an engine out of cast aluminum sometime. Definitely something I want to try.
I know this is a couple of years old now but I just found it. Wow! Very Impressive!!
I like the way you handled minimizing the crankcase volume (by not having one). A buddy and I tried to convert an old air compressor into a 2-stroke engine (almost 40 years ago now) but our crankcase volume was too large & transfer ports too inefficient to provide much of a charge volume so it wouldn't quite keep running (using a drill to start it, it would run but slowly slow down and eventually quit). It produced a net negative power output...
How is spark handled? Are you generating spark at a constant ~60Hz thus locking the rpm to ~3600 or do you have some sort of crank position sensor triggering the spark?
nice job makerj101
So beautiful! Just subscribed! =)
+Chris Fredriksson Thank you!
hi
i have watched all your previous videos on making this engine and i would really like to replicate this engine in the summer if you dont mind :) but i am wondering as i have never made an IC engine what recommendations do you have when making an engine? and also an ignition system that would work of this engine is a old magneto of a stationary engine :)
thanks
- olly
What a cool dude.I'm humbled.
+jtjjbannie Thank you!
you really made it, i like it....!
It took me a minute to see how the engine worked but it's definitely a two stroke and it's if the port-piston induction type. it's design is very interesting though. Unlike most small two cycle engines where the air-fuel mixture is drawn into the crankcase and then squeezed by the downward stroke of the piston until the induction ports open up and allow the air fuel mixture into the cylinder. This engine has the bottom of the cylinder sealed and that acts as the chamber where the fuel is drawn into and squeezed. I see the box of copper on the side of the cylinder must be the induction port. You should try adding more of these boxes to increase airflow and power. The carburetor seems to be of the vapor type. Very nice.
+Ben Heatherman you are 100% correct! You are the most observant commenter yet! I chose to seal the bottom of the piston because the stroke was very long in order to get the compression I wanted. I felt that the crank case would have been far too large to build up enough pressure on the down stroke to effectively push enough fuel through the ports. Like wise I felt the vacuum wouldn't be with to even open the check valve. I had to create such a long stroke because I designed this engine around a full size weed eater spark plug. There is a lot of area around the contracts of the spark plug so in order to create a high enough compression with such a small cylinder I needed a super long stroke. At least I have relativity high mean piston velocity. Might actually be way this engine is fairly efficient for being homemade. BTW you know what it piston is made from right?

I think you mentioned that the piston was made of JB weld correct? Yea making a crankcase with a smaller volume would be much more difficult than sealing the bottom of the cylinder. I don't know if you've ever had the chance to look inside a normal 2 stroke engine but the crank cases are VERY small for that reason. You mentioned you were using Viton "O" rings as piston rings. That's very neat I never thought of that using that, but I suppose it makes sense as many 4 stroke engines now use Viton for the valve stem seals.
Looks awesome
Not bad ! Have fun !
nice work man👍
try building twin or four cylinder ic engin, i would love to see that.
Nice to see it running. Did you mix some oil into the fuel to lubricate the piston?
+1shnitsel Nope. It's pure coleman fuel. The yellow color is from something that leached out of the cork seal I am using on the fuel jar. The oil comes from the drip oiler...
Great job - I've subbed.:)
congratulations im happy for you
Muito legal. Gosto de ver teus motores porque você não copia de ninguém e cria tudo novo.
That's pretty slick, have you thought about maybe doing a magneto igniter set up with it instead of running it on mains power?
+Danny Monarch Yep! I hope to get that working soon!
hey ! this guy is running amazingly!! next step fuel injection!
Seriously jelly jar "grandma I want a peanut butter and jelly sandwich" XD
Dang that's really cool!
yay sound like a proper two stroke :) now please make an expansion chamber for it :) would be really cool
+MrSlehofer I've thought about that. I'm not sure how to design it though. Do you have any idea how to calculate the shape or size I need for this engine?
+Makerj101 yes I do, this is the best for really small engines and it even has an app so you just enter the intake and exhaust port degree location and some rough exhaust temperature and fuel type and it calculates just perfectly: www.mh-aerotools.de/airfoils/javapipe_en.htm
........verey nice your work thank for your video
i think you should definitely return to this project and construct an expansion chamber for this engine
excellent job. also, I think you might be able to generate far more power with a bigger stepper motor.
What is the of valves you use in adjusting the ratio? I am building a lenoir cycle engine (non compression) and i will be using vapor carburetor too.
Really interesting, and how do the valves work?
amazing job!
There is a little flywheel energy calculator on the net if you search. I guestimated the figures for your flywheel at 800g 120mm and 2000rpm which give you a KE of 32 joules, about the right ballpark, ie 1/25 hp.
Never took one apart, but the cell phone charger probably works by rectifying the AC to DC and then cutting off anything over a desired voltage, probably 5.1 volts., so 20 to 30 volts DC input is fine.
OK. This kid is smarter than me and I'm 40.
What do the hours per gallon equate to?
This is freakin AWESOME!
Wow .good job kiddo . You should get in touch with JB WELD company and sell them the rights to advertise their putty with your device .And request also some big trucks loads of it .So you can scale up your project .
I think that you will find solder much superior to JB weld. Great project, very clever.
This is awesome. do you know how much torque it puts out with that wheel? It'd be really cool to see some wheels on it and have it drive around.
+Max V. I'm not sure. I've been wanting to make a prony brake to test that. But I just haven't yet. It would be cool to see it driving around! Something I also want to try!
good job ... i am impressed
+Raymond Lopez Thank you!
Well done....
now make a clock from a clock, thats some impressive meet the president shit.
+Brad Ferguson Where are all these clock references coming from? A whole bunch of people have just mentioned clocks in their comments and it's confusing me...
Friend:(walks in room with hands over his ears): WHAT IS THAT NOISE?!?
Maker J :(Yelling) IT IS JUST MY PHONE CHARGER!
P.S, Nice job I do not know any one that could do this even with proper tools an you basically used just junk and it runs great!
How are you timing the ignition?
If you can get a good neodymium magnet on the crankshaft. You could use a pickup coil to drive the spark. Move the coil to change timing. that's how mowers and weed whackers do it. Not sure if they have transformers built in to the coil. I think one coil of many turns might do it.
You could drill 2 holes in the side of the flywheel, one for magnet and an opposing hole to balance with lead.
+Mongrel Shark I'm not timing it! It fires whenever it wants to and somehow it seems to work very well. It blows my mind that it doesn't fire too early and self destruct. I've been thinking about a way to do the timing better. I might try going that route with the magnets or my other thought is to use an ignition coil and contacts.
Comprimise. Ignition coil, magnet, reed switch.
A reed switch would get murdered pretty quick at 3,000 rpm. Not even considering the back emf from the coil. I was using a momentary switch and it self distrusted when my engine jumped to 4krpm. I think I'm going to use a hall effect sensor and MOSFET. Should be able to handle things pretty well and be fairly efficient.
