Very good then may I improve on your design (got some engine knowledge)
@@Diesr Go ahead, that's what it's there for lol
@@CamdenBowen ait
@@Diesr any luck so far? Still printing parts out myself lol
Do you happen to have cad files or an assembly? I'm interested in looking at the design but it's challenging when it's in the form of STL files.
This little engine is getting more advanced every episode! Cannot wait for the next one!
same i cannot wait omg !
You know its a good day when a maker uploads a sick project
Man, keep up the great work. It's looking more and more like an engine each time!
Using nails for valve stems worked perfectly. I was able to make airtight valves that required little spring pressure! Thanks for all of your suggestions! Good luck out there!
Glad it worked out! Thank you!
@@CamdenBowen :D
Things are going to get so much more fun when metal 3D printing becomes more affordable.
I was really happy to see this video! I'm glad you haven't given up on it. It's cool to see the progress even if it isn't yet successful. I like where you are going with this. I believe reducing as much friction and mass in the gear train for the timing/valves could help, It may be that the piston can't overcome that load. Thanks for the video!
That's a good suggestion, The gears may create a lot of friction but from what I can tell most of its resistive forces are due to the compression stroke. Thank you!
LETS GO YOURE MY FAVOURITE RUclipsR
Cant wait to see where this project goes. keep up the great work
Lots of comments saying to 3d print in metal, or cast the parts, or you could use a 5-axis machining centre but I think the point is to see what can be done using what is at hand, a 3d filament printer, hand drill and a few tools.
Thanks for the series Camden
Loving this series. Convinced me to try my own 3d printed gas engine. Came back to see how you where handling the ignition timing, and spotted this new upload. Keep up the great work!
Thank you so much!!
This is getting so close to working! I think the only thing preventing it from working is the valve size. Maybe try increasing the bore of the engine so you have more room for the valves.
I was thinking of stepping the bore up, I just need to find a cylinder sleeve to use
@@CamdenBowen Maybe try and go to Lowes or somewhere and find a pipe
I think the reason why you keep running into issues with your engine is because you 3D print it out of FDM. Try SLA, which should help you get a much better engine due to its heat tolerance.
I own an SLA 3D Printer and once tried to burn some sample prints from my SLA 3D Printer. It didn’t really melt but anyways...
Hope that helps!
Also I’m thinking about taking on this challenge myself, although my 3D printer is broken at the moment.
EDIT: Oh yeah, another plus of SLA 3D Printers: they are great for air engines that NEED A LOT OF SEAL. Seeing that this engine probably runs into a LOT of sealing problems I think you should try using an SLA 3D Printer.
I do think that I need to try an SLA lol, I'm thinking of getting one myself for projects like these.
personaly I think its from the fact that its plastic
You and Tom Stanton are absolutely mezmerizing to watch. Keep it up man!
Your awesome. Youve got a lot of drive ☮️👍
Thank you so much!
@@CamdenBowen yw
Have you considered using a “bubbler” carburetor by drawing air through a closed bottle or something to mix the air and fuel vapor?
I haven't but it seems like a good idea, I just don't know if the engine has enough displacement to draw in enough air and fuel
This series has been sick asf to watch, I'm excited for episode 5
I kinda had a panic attack and then i clicked on this video and it went away thank you.
you should try a 2 stroke i believe it has less chaos but Im no expert keep up the good work
The first version I made was actually a two stroke, however it had a poor design and never worked. I wonder if I could try one now?
The way your engine backfired, I would look to the ignition timing. If you’ve got good compression, valve timing is good, but I believe ignition timing could be advanced a bit.
All of my model engines took a considerable amount of fiddling to get them running since scaling down makes for difficult running.
Also, butane, as well as all LPG products, tend to require s richer mixture than the longer chain hydrocarbons. This means a smaller venturi as opposed to one for naphtha (white gas, aka camping fuel).
Nice work, interesting trouble shooting methodology!
Thank you! The tolerance between the gears may have disrupted the expected ignition timing as well
Love how the project is coming along! Next time can you duck the volume when the drill is running? It was so loud I had to keep turning the volume down, then when you started talking again I couldn't hear you and had to turn it back up which was a pain and made the video difficult to follow
If I can ask, do you have a hearing problems or headphones?
@@cenreaper9127 I have auditory processing issues that make things like vacuum cleaner motors and electric drills painful to listen to, like the proverbial nails on a chalkboard
@@cemmy410 Oh. I'm sorry 😔 about that.
Sorry, My headphones aren't very good and I may not have noticed lol
The main problem is probably the air/fuel ratio. For the ignition you could try some 18650 batteries instead. I find them more reliable
Yea, these 9v are pretty unreliable after a while, but for short periods work fine
Must watch a bunch of Nile Red videos! 😂👍
Chemistry is that one class I was good at yet never liked lol
Put a metal pipe on the piston and cylinder in the carburetor to have a good seal. (Or just put some kind of a plastic membrane as a seal).
I could but I don't have any that size, it isn't subject to much pressure so it doesn't really need a perfect seal
@@CamdenBowen Maybe that low amount of pressure you ignore is making your engine still dead.
Realy nice, the videos on this project are always interesting. What are you gonna do with it when it runs?
Either modify it or just blow it up lol, It'll make a cool video
@@CamdenBowen might be cool to put it under load and see how it fairs. Maybe forced induction? :)
Nice episode again! I have something you could build im the future: A starter motor, then, you would not need a drill. I don't know how long it would take, but if you have a good idea, that is build fast, do it, would be really nice!
Thanks! The reason I chose the drill is it has enough torque and speed to make an appropriate starter, a starter motor would have to be pretty big to make it work right and it could be a bit of a hassle
@@CamdenBowen Yeah, sure, I understand, why you used the drill, but I thought, maybe you can find something, that would work as a starter motor.
Bro I was just reviewing your RUclips channel 1 hour and 27min ago
Making a engine with a really low bore-stroke ratio may be a good idea as it will want to run at a lower rpm and will give the butane more time to move through the intake and into the cylinder. And I know you already increased the weight of the flywheel, but increasing it even more may be a good idea. Single cylinder engines are not the best at idling smoothly (usually need to idle at 1500-2000+ rpm to be smooth) and with a weak power stroke I think it'd be hard to get it to run without an almost excessively heavy flywheel.
I really need to get my hands on a 3D printer, I've been thinking of experimenting with 3D printed ICE's for a little bit, which is the main reason I ever discovered your channel. You've come a good way from the first video, I'm sure you can make it happen.
I like to use Alcohol soaked nylon as temporary gaskets, works pretty well until I finish a prototype and want to actually buy proper gaskets and seals, even non-soaked nylon works decently since it's a softer plastic
Do you use it for metal on metal?
@@CamdenBowen Not usually, though I did use it as part of an attempt at making a compressor, rubber and silicon have much better seals, but nylon works as a temporary testing gasket. I think the only time I used a nylon gasket metal on metal was when I made an air powered dremel that blew up in two seconds because I didn't make it strong enough for anything over 40 PSI. It was basically an air engine with an aluminum pipe as the cylinder wall
evangelion music shinji get in the 3d printed alcohol engine
My man made a 3D printer forge burner lmao
Desperate times call for desperate measures lol
@Camden Bowen I chuckled so hard seeing the Itty bitty yet perfect burn on it
i thought it was a lego piece in the thumbnail
Is there any chance your intake valve is too small? The fact that you can hear popping says that the engine has all 3 components of combustion. I think the only thing you may still be missing is just more air and fuel. I know with your cylinder head design it may be difficult to increase the intake valve area, but if you could find some work-around, it may fire right up
I was thinking of stepping the bore size up and fitting larger valves, it may help reduce resistance as it will breathe easier
The results from your material test make sense. Nylon is the worst for absorbing moisture.
i see the playlist has 5 videos with 1 hidden. did you release next part? Great series :)
Actually no lol, it was an update video involving it where I did literally nothing important. Thanks!
The fly wheel needs gear teeth on the sides so you can build what amounts to a bendx you can spin with your drill
It's possible there simply isn't enough fuel in the cylinder to make enough power to kick it over
If it's run giving it a water jacket will be awesome
You can eliminate almost all shaft play while saving space by using two angular bearings in a tandem configuration
I think the problem is timing/the drill rpm is not fast enough.
I had a hit and miss engine kit and tried using a drill. I had to attach a wheel to the drill to start my engine.
keep on goin man fk yea
Plz part 5
I'm doing my own engine project. I'm still in the stone age trying to figure out how to make over head cams :P
A twin-cam setup would be pretty cool if you got around to it!
i would recommend to pull start it, the drill spins it too slow
It isn't going to spin much faster but also, it won't spin for long enough to start
love this project, are you still working on it, its been five months.
Probably not for a while, if I do it will be in a much larger displacement as I don't think this engine can run easily on a small scale
we need an update on the 3d printed motor
a tip i have is use pure alcohol or at least 98%. if you use 98% then it has that whoof like gasoline. 91 is pretty weak when it comes to flammability
Bạn phải làm lạy buồng đốt và pitong bằng đòng nó mới hoạt động chúc bạn thành công😀
you could try nitro mhethanol its mainly iused in rc engines or dragsters
I would love to print this awsome engine by my self and tets it. Maby you could upload them on Thingiverse.
Yea for sure! I will post publicly when the files are up
Can you upload the stl‘s somewhere?
I am going too soon I just need to gather the right ones
It feels like a timing issue not a fuel issue.
Try a rotary style valve instead of the standard push type. You may be loosing more compression than you think.
I thought about it, I would just need to figure out a design for a seal around the stationary parts of the manifold that seal against the disk
@@CamdenBowen use a roller pin style valve. Think a hallow tube with ports on the side. Then you can drive it like a normal cam 2:1 drive gear. Plus orings can seal it easy.
@@CamdenBowen you could try a reed valve for the intake. Then you only have to worry about the exhaust side.
3-D print a tesla turbine gasoline engine for another video
I love your ideas and i had the same project idea on making a diy gassolene engine. Any tips and your mind on linus tech tips?
My advice is to do plenty of research as well as practice, maybe consult forums about specific information you are unaware of it helps a ton! I watch a bit of linus sometimes!
@@CamdenBowen linus sex tips?
linus sex tips
@@CamdenBowen
i wish yor little engine working propeply :)
where do i find the files i wanna experiment and improve
I was going to upload them later on, I need to gather all the correct ones
@@CamdenBowen lol sounds awfully familiar (trying to find files)
Try to spray some brake/carb clean into intake
im sorry but what is PTEG? do you mean PETG?
Yes
dude butane is gonna melt that copper sleeve if that butane gets to its maximum
i don't wanna be that guy, but it's PETG not PTEG, sorry it had to be said
I had realized this after lol, too bad RUclips removed annotations
You gotta get that piston as close to the top of the cylinder as you can get it to make more compression there's just to much space in the cylinder
Internal combustion engines want at minimum around 15 to 20 psi of cylinder pressure to even run poorly
What fuel line did you go with?
It's just a pneumatic tube, I believe they are made from PTFE
when part 5?
The O-ring causes friction replace it with nylon rings and the rings has to be a 3D printed
hehe engine go broooom
brrrrrrrrrrrrrr
Did something happen to one of the parts in this series? I'm mostly curious, I don't want to be annoying
In truth, the project was for more ambitious than I was anticipating and I was getting bored. I'm much more satisfied with my more recent stuff
@@CamdenBowen You should list the video! I'd love to watch it despite whichever outcome came to light. I'm sure along with that everyone enjoys your new stuff along with it
It needs more compression most likely
Use a rc nitro carburetor style
I was thinking of it but In don't want to buy one lol
Make a hho generator and shove into intake becuase thé oxygène and fuel IS already there and seal it from outside World
I could but that would be too much work, making a whole hho generator for an engine that isn't running yet
@@CamdenBowen its not powerboost nor anything it will solve fuel problem to make running therefor its not a problem if engine wasnt running
@@laabarnaceur2134 might be dangerous running highly concentrated hydrogen and oxygen in a engine of this size. Lotta punch for plastic parts.
@@quesadilla7760 thé cylindre inside IS made out of copper
How about solenoid valves. Instead of cam driven valves.
A fun idea, but in practice on this scale would be likely to fail. On a larger scale however it could work
2:07 that is because your nylon is too wet in most cases.
It's PETG
I'm a mechanic and a self proclaimed engineer. Your rods and rocker valve trane isn't as accurate as it needs to be. Use a top draft carb. And a over had cam shim over bucket design
try fuel injector
its petg not pteg
Love watching the videos because of the content...but your production is so distracting
Microphone. MICROPHONE.
wtf happened to your hair?
better not be too successful with this idea otherwise car manufacturers might get some terrible ideas
Unfortunately I've already succeeded with it, dodge better not take notes
