Part 5. DIY Internal Combustion Engine Made from Old Compressor - First Run and Copper Head Gasket
Вставка
- Опубліковано 11 сер 2017
- Part 5 is finally here! First we measured the compression ratio using a syringe and water. Then we made a new head gasket out of annealed 12AWG(0.0808 in)(2.05 mm) copper house wire. Then we soldered the ends together to make a continuous loop that would make a good seal. We then drilled a third hole in the cylinder which is the intake port(the carburetor will eventually be mounted on this hole). Then the most exciting part, I squirted some fuel into the intake after hooking the spark plug up to an neon sign transformer and used a piece of rope to start it. It sounds like an angry weed eater!!!
BTW sorry for the long delay in posting this video. I have been very busy. I was helping out a lot at my local makerspace, HackPGH. I was helping build a flying machine for the Red Bull Flutag. I was the pilot. Good thing I didn't die! If you noticed the scratch on my head in the closing that was from my craft.
Why? Because it will be a challenge and I like a little challenge. The main constraints that I have put on this project are limited power tools. I will only use a battery drill, hacksaw, and other common hand tools and materials. Working with constraints are what real world engineers basically do and I find it challenging and fun working in this way. There are three reason for trying to do this with minimal tools: 1. so anyone, even someone in a third world country can replicate. 2. to show what you might be able to do in an apocalyptic situation. 3. creative thinking. I hope you enjoy. Please leave ideas and suggestions in the comments below!

Boy I don't know who was more excited. Me or you. I'm 71. Enjoying your enthusiasm.
Hahaha
Holy cow. I have to admit, I was sceptical. Especially when drilling the hole for the piston-gated intake port, it seemed your drill alignment was pretty far off your mark.
That combined with the "I guess it would go here" placement if the transfer port and the exhaust port, I thought it didn't have much chance of actually running.
I stand corrected, you are a genius.
Haha I was winging it pretty hard, eh? Yeah I noticed how far off the drill was when I was editing the video! I never noticed that when I was actually drilling it. I'm surprised that didn't mess it up. Thank you for your kind words!
I'm surprised by the apparent stability for such a thing
@@makerj101 People like you who do often have an sense of whats right vs the textbook. *pat on the back* clapping way to go bro!
Running is one thing making power is another.. however this project doesnt seem to be about power.. just experimenting. Super cool engine man props!
Future build series " today I will build a nuclear generator out of a toothpaste container and a napkin."
"today I will cure cancer with a toothpick." :D
somerandomcamel hahaha MacGyver
Makerj101 more like today I will cure cancer with an upload
I cant believe you got that running that fast!
Yeah me too! It's pretty well balanced and being such a small engine it kinda has to be a fast runner. I'd guess it was easily going 6-8k RPM. Small nitro engines go like 12K RPM
I wish I could find a compressor myself and build along, it would make a neat rc engine.
Makerj101 Actually some 3,5cc nitro engines rev to 28k rpm, my modified 50cc moped revs to over 13k rpm
Lol I bet that moped sounds dope.
Ruben Olaussen actually rc engines rev up to 50000 rpm
15:14 now THAT'S what i call fuel injection!
15:40
Yesss I just got on the toilet, looks like I'm gonna be sitting here for the next 20 minutes
Hahahahahahaha 😂😂😂
me too lol
THE STARS HAVE ALIGNED, THE INTERNAL COMBUSTION ENGINE HAS HAD JB-WELD APPLIED
I'm surprised it ran that well on a constant arc. neat project.
Yeah me too! Thanks!
It should not work 🤣
This is great! With a proper 2 stroke exhaust and a good carburetor, this little engine can get very fuel efficient! With some old automotive parts, a simple ignition system shouldn't be too hard to fabricate. When you're going to use premixed gas, i recommend to use synthetic oil for this type of engine.
Ive been waiting so long for this. I've been watching your videos for a month now. I am 12 years old and always loved unique and homebuilt engine and you have inspired me to build a strling engine you are my favorite UA-camr and my biggest inspiration.
I apologize for the long delay. Cool! Contact me if you have any questions about building your engine! And definitely let me know how it turns out! I'd love to see a video of it running.
Proof of concept achieved, I applaud you man.
Dude, you're the kind of 'maker' that makes this country awesome. I have a job for you when you want one.
Great Job! I was planing to turn a 4 stroke engine into a 2 stroke engine and see if I can get more power that way, It was great to see your engine finally running!
Hmm well in theory you could because you are getting twice as many explosions. However you would also be loosing a lot of benefits of a 4 stroke.
Yeah it would be a cool experiment though, I was thinking of using one of those 212cc predator engines from harbor fright, maybe put it on a gokart and do a top speed run before and after, would make for a interesting video at least.
Sorry but it would be cheaper to buy a two stroke engine
well you can get one of those engines new with coupon for like $100, you cant find a 2 stroke engine that big for that cheap, but anyway that's not the point of doing it, mostly i want to do it because those engines are often used for racing go-karts and they sell many mods for them, but I could pretty much turn it into a 2 stroke for almost nothing and It would just be fun to see how good it works. (For entertainment purposes only)
a piston that size would cost mayby 50 bucks for a knock off winsco. the head atleast 100. by the time you get done with it you could of bought a CR500 off of craigslist
I would love to see your take on the rotary engine
If I can make it out of solid JB Weld then YES :D
XD JB Weld rotary. Now that I'd like to see.
Hehehe XD
I'll give it some thought
Makerj101 actually some aircon pumps were wankel, so you may be able to turn it into an engine fairly easily
OMG Thas is sooo cool, great work :)
Man you are going to be a great engineer, half the guys i go to college with dont have any where near the knowledge you do and I am an engineering student myself, I repect you a lot dude, keep up the good work.
Thank you! See that's the thing. I don't know if engineering is what I want to do. I don't know if my hands on skills will be used to their full potential by doing engineering. Good luck with your studies!
I am trying and struggling, like you i have a lot of hands on skill, but I am also very good with my mind, numbers and such. I love fabrication work and welding. I love your videos, and have been watching them a long time. Only one note; on the JB weld it tends to get brittle after a while, I am not sure how well it will wear, but the crank case isn't high pressure, so it should be ok for a while. I can't wait to see what you do with this.
Watched this 3 times now. We need part 6!
I was right there with you. "IT RUNS!!!!" Awesome job. Can't wait to see more.
Really cool stuff. Can only imagine what people walking by would think
It's a pretty normal sight in my garage by this point! :P
Awesome work man!!! I used to have 4 old refrigerator compressors lying around and always planned of making a 2 stroke but never thought it would work due to the short stroke. But you've prooved that it can be done!!! Congratulations!! Can't wait till the next update
For future reference, copper actually hardens when you let it air harden. It only softens when you quench it, best in water. Only carbon steel really hardens in a quench. I'm a hobbyist metalworker and knife maker, and I have messed up air cooling copper before and then cracking it when I bend it. It's a common misconception that copper anneals in the air. It hardens the crystal structure.
Great video by the way. I love this channel, I'm glad you've gotten so many subscribers. Here's hoping you get even more!
Very well-experienced for a young guy! Your tutor must be very proud of you.....more from you please...YOU ARE A GENIUS!
I got hooked on this series a few weeks ago after stumbling upon episode #1 quite by accident. This is an awesome little project. Reminds me of the kind of stuff we used to do for fun as youngsters in a world before XBoxes. We need more future engineers like you!
I'm so happy you got this running maker J. You put alot of time in this. This is incredible! I wish you much more success!
Anyone can go and buy a cheap wacker engine but that's not the point, it's the fun of making a engine out of nothing. Your parents must be proud of you. you are a genius
I just stumbled upon your channel. I backed up to Part 1 and watched everything from the beginning. Can't wait until Parts 6,7,8,9, 10, etc, etc!!!!!!
Hammering a centre drill with an adjustable spanner will have had some machinists rushed to hospital. Brilliant.
WOWWW THAT RAN WAY BETTER THAN I THOUGHT IT WOULD!!! DAAAAYUM!!!
That was awesome for a first try!
And you have absolutely no problems of worrying about no spark EVER with that constant spark thing going!!!
I didn't even know you could run it like that!
I believe we have a new MacGyver! Great stuff! Keep it coming. Thanks.
I always tried to build one of these engine i wanna to find on UA-cam some vid abaut this engine 1 year ago and there was nothing about
That i'm so Happy i found this channel, and You awesome guy i Hope You don't stop this project
There are actually quit a few of these engines on UA-cam that I have found after starting this project. They are really hard to find because most of them are in other languages so UA-cam seems to hide them from English viewers. For example: ua-cam.com/video/MmDKRtdGHQQ/v-deo.html
Thank you! I hope you go back to your engine project and get it working!
Congrats! That looks like fun. Nice build. I really like the way you work.
I agree that was Awesome. I was happy to see it run. Keep up with the great ideas it's very entertaining to watch. thumbs up!
That is really awesome!! I was hoping for something that would turn over once or twice, but after seeing that run, it looks like you will have an actually practical engine. That this was done by a young man as yourself with just basic tools is pretty amazing.
Thank you! Haha well that'd be down right disappointing and I'd never have even attempted this project if that was all I was expecting! I guess I will have to test the reliability of it too and see how many hours I can get on it before things wear out.
thats badass man keep it up!
Wow that's quite impressive. You've done quite well you can be very proud of this!
That is awesome! I didn't expect it to run that well on the first test and it definitely disappoint! I Can't wait to see it with an actual carb and ignition!
Wow.. I just found your videos.. and like em! You are like a real life Macgyver! Keep up the good work!
Wow, i really expected this to need Tons of troubleshooting before you even get your first ignition! Awesome that it ran that well first try!
Pretty cool work dude! After building engines for over 15 years thats impressive to me
That is pretty awesome dude! I guess I was as excited as you were when it ran!
You just inspired me to have a go at building one myself! Thank you for those awesome videos!
Soldering on a gas cooker? Now I've seen everything xD
I'm so glad it runs dude! Like you said, you definitely need a carburetor so you don't accidentally flood the engine (again haha). It might also be worth your time to design a proper exhaust pipe for this, since 2 strokes work best with a tuned exhaust; more power and much better efficiency due to backpressure. Pullstart is fine for now, I'd worry about making it work as efficiently as possible first before slapping a genny on it :)
Hahaha well since I'm trying to make this possible for anyone to make. And lots of people apparently don't have blowtorches sooo...
Thank you! And yeah carburetor is coming in the next video! I'll think about an exhaust pipe as well. That's a really good idea. Maybe I'll make an expansion chamber! :D
Wait really? I have a blow torch, but I don't have a gas cooker... haha
No worries bro. I'm so excited to see how you'll improve this engine. Good luck! :D
That's amazing, I never would've imagined it would work!
Just came across your channel by accident, 1 video and I'm hooked lol! Great video! 👍
Ok that is just awesome! Never expected it to run so soon.
I am so amazed that worked without spark timing, congrats!
Haha, it cracks me up how excited you get, because I would do the same. Nice work! :)
Tihs is the only series I fully watch on youtube!
Dude you make the sickest stuff man. Great work.
Thank you! :)
That is absolutely quality, love it good on you
Thanks man!
Awesome! I enjoyed your video series, great job in getting that engine up and running!
I love the enthusiasm, great job dude!
Succes tinere,dacă continui aşa viitorul îţi va fi plin de aventuri.
This is very exciting, I can't wait to see the carburettor. I also liked the copper gasket. When you made that, I was thinking, well, that's what they use in steam locomotives, so it should be good.
Well I haven't even started building the carburetor so I am excited to see it too! :D Yeah that's true, I hadn't thought of that. I thought of the idea when I was looking at the spark plug the one day and the crush ring on it.
you never cease to amaze me. Kudos.
It's a shame you don't live closer to me. I have a fully stocked machine shop. I shutter to think what you could do with access to all the proper tools to build whatever. Keep up the good work. You prove you can do a lot with a little.
Runs great! It will be interesting to see the carburetor.
Awesome job man! That's really cool.
Thank you!
Very cool project. Good luck!
This is pure amazing. I thought it could be done and now i know it can! Next hake a 2 piston compressor and do the same thing!
I feel like a kid on christmas morning when these videos come out
very nice job and congrats on the first start.
Very good job, I'm very impressed.
NICE !!!
Keep it on.. cant wait for part 6 and 7 :D
"Oil in my eyeballs", no, those were tears of joy :D Runs awesome considering the methods used to make it, goes to show that 2-stroke is as simple as it gets, pretty much.
That's some fine work! Color me impressed.
Woo-hoo! I've been waiting so long for this.
Love the "Its alive!" moment at 15:40
Im glad you got it working first time, hope the next video wont take so long :)
I'm really impressed. You're great !
That is awesome. Keep up the great work!
Thanks!
Awesome work!
This is awesome man. Brilliant.
That's awesome!! Why don't you mix a little bit of 2-stroke oil with your Coleman white fuel to help with lubrication
I'll save that for part 8 when I do the official run! This was only a test. :)
Makerj101 oh cool :)
Great idea but how do you classify this? 32:1 40:1 etc... ? I'd use Marvel Mystery Oil... I know a hot rodder who swore by it in his Chrysler 440 for top valve lubrication. Target sells it.
I'd use 25:1 for this.
Although a normal 2 stroke has ball bearings. This has bush bearings so will 2 stroke style lubrication be sufficient or will the bearings fail. Time will tell I guess. Running it on LPG/propane wouldn't dilute the oil like petrol would therefore maintaining the viscosity that those bearings were designed for.
Dude that awesome! Now I want to build one.
Excellent ! Many of the old spark ignition two stroke model airplane engines have a baffel across the top of the piston. This is to force the incoming fuel charge up and prevent it from simply shooting straight across and out of the exhaust port.
Yay. Been waiting for part 5!!
That excitement is precious...
Congrats man, that is awesome! Sounds better than my weedeater for sure!
Excellent, good work!
Good job! I'm surprised how easily this was turned into a running engine.
Yoooo that cylinder head is a slick idea!
Awesome to see it run!
Impressive little piece of work you have their kid! I predict you will one day be an engineer.
All the best!
Mike
You should get one of these cheap humidifier module to generate mist from fuel, it works really well
A generator you say? This interesting project is becoming very intriguing... we will be watching, always watching *ominous music plays in background*
Hahaha That's just great! :'D
I do my best.
I cannot wait until we see more of this project, I am absolutely enthralled by you and your process throughout all of the projects! please keep them coming :D
You did it! Awesome video series!
You did a very good job
Glad to see our country is still alive!
For part 7 you might look up MSD spark boxes which is basically what your neon transformer is doing. MSD = Multiple Spark Duration, iirc. Great project!
This is awesome! Keep it up.
well done dude ...good hard work
IT'S ALIVE!!!!!! Congrats on the first run. Glad to see you read my comment and fixed the compression ratio xD. Try to make a bracket to mount a small weedeater carb on, or just make one of your old jar carbs. If going jar use different tube diameters to adjust air/fuel mixture. Add smokeless 2 stroke oil to your fuel to keep it alive >_
Good for you that was impressing great job.
That engine is just awesome man!
And at the end when your dad was there i just couldnt help but laugh a bit, that moment when your engine is finally running and you excitedly shout at your parents to come and look xD
it's alive! congratulation!!
You got it man , Great job ! Thumbs up ..
That was great bro 👍
Awesome work 👍🏼
Great job. It is an awesome achievement.
I love your videos you are awesome and keep inventerizing
Thank you!
