Finally Upgrading my 3D Printed VTEC Engine, Then DYNO Testing it
HTML-код
- Опубликовано: 29 сен 2024
- As per viewer request, I decided to start working on my VTEC engine once again. I worked to make the engine's VTEC kick in automatically similarly to how it would on a typical Honda engine.
BTW, This video features me yapping a whole lot sorry
FILES: drive.google.c...
I forgot to upload the files until just now hehe, they're in the description
cool
How does someone like you not have 500,000+ viewers by now? I've been watching your videos and it's nothing short of quality. Keep it up dude. Youll go far ❤

I have an idea about the 3d printed gasoline engine I think the problem with the carb setup is that there is not enough air volume to suck up and atomize the fuel so I have 2 Ideas
1) use butane or propane as a fuel use the existing carb and plum butane into it and use some sort of valve driven by the cam shaft to open and close the butane tank as too much butane won't ignite
2) if you don't want to use butane as it's a gasoline engine try placing the fuel tank above the carb's fuel inlet and use some sort of valve similar to the one in butane setup
( I recommend that u increase the diameter of the intake valve as I think it's the main bottle neck) I hope this helps waiting for part 5 of 3d printed ice
Also I recommend that you get rid of the venturi setup and use direct injection into the intake and use a valve of timing of fuel
now run high octane through it
shi 93 octane that would sound amazing
A nitrogen tank
Nitromethane
Too little. He should rut it with nitroglycerin
Or E85
Man, its fun to see a series of progress on a project like this. And as you can see by the numbers, it is fun not just for me. If youre enjoying this, please continue
So he basically reinvented the 2 stroke power valves? Absolute legend ‼️
This series has been awesome throughout.
As a former auto tech, variable valve timing is one of those "damn, that's brilliant" things when you learn how it works.
After watching this video, I find it fascinating how I've gained an understanding of various concepts such as horsepower, torque, and the mechanics behind the dyno. Although I can't pinpoint the exact reason why
Has anyone else noticed we have seen an absurd jump of quality engineering related youtube channels? Feels like every other day I get recommended a video of some guy doing crazy things with a 3d printer and well edited videos with few subs lol
glad you blowing up i realy like your content and i woud like to see more of it specialy cuz your ideas are not that boring like other peoples
Nice af. You deserve all the attention.
@CamdenBowen You should reengineer it so that you can put oil in the engine. It won't heat up as fast as should lubricate everything. Might fix your crankshaft problem
A twin cam head would be sweet to see !!
Perhaps this could ultimately be powered by a pressure chamber that generates its pressure via mixing dry ice and water, or perhaps even liquid nitrogen and dry warm water. Then the system could be self powered. Air powered go kart?? 👀
That dyno took way more effort and money than an arduino and a hall effect sensor would.
Well, unless you're really bad at both programming and finding ready solutions online, then it's probably really hard.
If you're worried about user repeatability then finding solutions using materials and methods anyone could copy could help.
You could absolutely do things using metal.
Ive learned from watching youtuber/rc and aviation hobbyist that you can get all sizes of brass pipe and easily cut it with a hobby razor by rolling it. You could use these brass pipes as sleeving and bushings for the crank and cylinder walls and other wear locations to reduce friction and heat, as well as increase longevity. Plus, its cheap and anyone with an internet connection can acquire the right brass.
I wish you could make an opposed cylinder version (that would increase efficiency a LOT
Or a boxer one that would remove the fatigue issue you have with smaller crank shaft
Actually, PETG is not universally stronger than PLA. PLA is actually extremely stiff, but a bit less "tough." It's a little brittle, but for a crankshaft, where you're not taking impacts, the stiffness of basic PLA is going to be better. Actual crankshafts (and camshafts even more so) are hardened for this reason. Dropping a crank or a camshaft can be catastrophic because they're very hardened, and thus brittle. But in the rotational engine loads, that's ideal.
After I saw the first one, I was excited for the next. Nice video!
What you should do for the bottom end and piston is add a liquid lubrication system. An oil pump and filter to get the engine running smoother!
you could have a small air port direct compressed air at the crankshaft for a cooling effect
having seen most of your videos I think you should hone your cylinder tubes, and larger print the piston to hone on the dimension of the honed cylinder tube, and the cylinder head closer to the piston, a car with high-pressure heads gets more performance
I’m surprised lego engines are able to survive this interesting
Brilliant idea using the back preassure!
0.00629hp is about 4.7 watts, which isn't too bad for a 3d printed engine. Your biggest problem for making lots of power is speed.
I found this one channel, cant remember the name, but when I get to it I'll link it. Anyway, he made a modified version of Tom Stanton's diaphram air engine, and made 12 watts at 9000 rpm. If you can get your engine to rev to even 3000rpm, I imagine youll make a LOT more power.
I think what would have worked better for me too is having the flywheel directly connected to the crankshaft and skipping the coupler. It added helped with shaft misalignment but also sapped power
I don't know if you know this or not but if you increase perimeters rather than infill it will be stronger. Nice vid.
do a shaft with a hollow centre so you can insert a thin metal rod for structural support
You should try at least 1 more cylinder to make it naturally balanced also possibly make where you have like 3 different intake cam lobes and have a secondary vtec at even higher rpm?
Heres somethin I thought about the crank. What about using a cut 3/8 allen key with the center ground smooth? You have the hex of the allen to stop the crank from twisting on you and a smooth surface. Now if you really wanted to you could put a bearing on that (yes I know you are wanting this to be all 3d printed) Just some food for thought
They make hardened pins you know. No need to frankenstein one from a perfectly good allen key.
if you want to make a more stable engine, scale the whole thing up by 25% and make the cilinder another 25% larger, less stroke and a balanced flywheel are going to fix your vibration problem for sure
At first I thought the crank problem said destiny! Haha
How is this myth of PETG being stronger than PLA still around? PLA is stronger and stiffer, the only benifits to my knowledge are that PETG is better for is impact strength and heat resistance, it also deforms before breaking which may be a benefit depending on the application.
Based on things I have printed PLA seems like it doesn't bind as easily when parts are rubbing.
CNCKitchen on RUclips does several material tests and gives out tons of great info.
Otherwise, this video was awesome.
Maybe that is true, but in my own personal experience I have found that PETG performs longer under stress than PLA does.
Inline 4... And I'm waiting for that next video my dude.
You should attempt a 4 cylinder (with VTEC) next!
Try using bearings on the shaft and use a metal rod between the 2 crank arms or use a bearing
Bearings are amazing pieces of tech aye?
Love to see a 4 cly version
Honda needa hire bro!!
really cool video! Can you publish the stl files so we can print the Engine?
COOL VIBRATIONS
I wanna dance
Neat! If I can make a suggestion: replace the electromagnet + pickup with a rotary encoder. Something like the E6B2-CWZ6C is very easy to use with an Arduino (using eg. the "Encoder" library). You'll get resolution down to the level of 0.001 degrees and they can handle pretty decent speeds
From the comment on not wanting to get into technology I think he wants to avoid things like Arduinos and buying electronics components, something similar to a brush from a motor and a (small) battery could make a less fuzzy output readable by his recording gear
@@crestfallensunbro6001 But... why? The setup I describe above is super simple and will get very accurate results - much more accurate than he'd need. Would cost
@@harrisonlow its mostly speculation on my part for the wanting to avoid micro processors thing, what gave me that impression was the way he used an audio recorder to log the data (valid but slightly unusual choice) and the comment about avoiding a certain type of technology
Great printed project. But torque is in Nm not N/m. And use just P=T.w. P in Watt. And w in rad/s. And then convert to hp.
Crazy idea parts touching or rubbing each other possible to glue an aluminium foil to it?
its bad that i learned more things on this then i do in school.
sick compressor bro
Maybe print the crank at a lower infill then fill the void with resin after?
Walls>infill - walls are far far stronger than infill - just make your perimeter count high enough to fill 100% of the part next time you're going for strength.
Interesting, I actually never gave this much thought. I'll have to try this next time!
You should make one with 4 cylinders that looks like a b16a
you should integrate bearings into the crank parts
Counter weight on the crank might help
You should
Try make it a I2 so the crankshaft problem might not return
You could make a boxer style engine with both pistons connected to the same crank…
I would love to know what parts you used that aren't 3D printed, do you have a list of parts you used?
Excellent
you should add a bigger flywheel to it so the engine takes longer to rev up
you should make the VTEC inline four
What if you use metal filament but you should use a stronger nozzle for the 3d printer
Hi! ABS to PET-G have bad friction. Try to print engine body from ABS.
You should either supercharge it or turbo charge it
why do you divide by 5252? i didn't understand that part of the math. is that like the diameter in mm?
Drake Bell's evil twin
Why don't you print with a iron-based filament or a steel-based filament? It would make it much stronger while still leaving it to be 3D printed
Build A TURBO for this. Can Imagine It Would Make A Great Vid
✨Mm YeS hOrSePoWeR✨
I’m pretty sure the “tiredness of sound the engine “ is bogging but idkk
Is it just me or does it sound like a Jake brake when he pressed the VTech button. I need to see a air powered engine with a Jake brake
You should use polypropylene for the crankshaft?
O-Rings on the piston violate the all plastic rule?
Not really, by virtue of that the screws would violate it too. I was more meaning that I didn't want to design it in such a way that involves cutting and welding but instead a part that can be 3d printed
Could you test the power curve with VTEC permanently on? I don't think that there's any advantage to not having the high lift cam in an air engine (at least not in this one, maybe if it had way higher revs and very agressive timing advance and duration, it would make a difference)
Now more cylinders
i love your videos bro. also i love how you admit how bad your handwriting is, but what is funny is that my history teacher had about the same style and is sometimes worse that yours (2:09).
Maybe, Just maybe, you could put a Turbo on it... Im not really sure if a Turbo would work, But you should try it... Maybe...
Cool, now make a turbo
A double acting engine would work well,
I'm no master of electronics and programming, but if you want to, I'd be more than happy to help you to get a better and easier dyno reading. Let me know if you want me to help you. I don't need credits or mention or anything in return, tbh
4cyl vtec all 3d printed as a proof of concept > then make a gas powered vtech 4cyl you can try put in a lawnmower or something.
One thing you could do to have a stronger crank could be pressing a metal rod/pin through the center. Could also use a long screw to achieve similar effect.
And adding counter weights
Forged Carbon Fiber?
I was thinking some sort of high temperature rated fiberglass filament. Not sure if you need a different head to print that though
@@ianbaker4295I’ve printed a few different carbon materials… it would be great IMO for stiffness and strength, but would need some good lube or post process. Also not sure how it would handle heat…
You could possibly print counterweights on the crankshaft to make it not want to flex as much from the piston moving, as well as drilling a screw through the print to give it extra rigidity.
Thats what I was thinking. Something like a harmonic balancer. I also like your idea of putting a type of simple screw or dowel in the crank.
Agreed
Real crankshafts have this, don't know how much plastic would make a difference because it's so light anyway so counterweights wouldn't do much unless they were huge. But, may be the only thing for longevity.
I like the video Camden!
Just curious though, did you ever try making the piston airtight? I’m gonna guess you did so my question is more, how did it go?
You gona make airtight lve or why ur asking
@@Kippo6969 lol what?
I wouldn't say airtight, but pretty close. I left about a ~0.1mm tolerance between the piston and walls and just added grease to make up the difference
@@CamdenBowen isn't the grease gonna act like a semi glue? i remember making something and high viscosity grease make it harder to turn, or stroke, (i dont remember what i make) so i used watery oil instead,. not sure how you do sealing with more watery oil though
@@mr.2minutes161 Yeah I kinda thought about that too
A lighter con rod and piston would reduce the force on the crankshaft. Also, the closer the crankshaft bearings are to the con rod, the less bending moment the piston force will have on the crankshaft.
I'm excited to see where this goes in the future. Possibly more cylinders? Perhaps putting the E (Electronic) into VTEC? Maybe even continuously variable valve timing/lift?
E - exhaust
I just wanna say it's impressive and amazing seeing the difference in confidence you have on camera. In the earlier videos, I felt you were a bit tentative but now you're just hitting us with a slightly more manic but more genuine self. I love it! I've always wanted to make videos but get hung up on camera presence and the type of content people want to watch and this is a big inspiration / motivator, that if I could reliably upload stuff I would hopefully become more watchable!
Thanks Cam this is a sick project and congrats on more than 10K subs! I'm sure it'll soon be more like 20K+
Thank you so much! Speaking to a camera is a surprisingly difficult skill since you need to speak to an inanimate object as if it were a person. It sounds easy, but what makes it so hard is that the camera shows no reaction to what you say, making it feel awkward always. Glad you can appreciate the effort!
do you have the cad files for the engine?
In the description
I love the cassette dyno! Also, that diaphragm solution is very clever!
Thank you!
You should make a boxer 4, this might help to balance crankshaft forces a bit. Or make something weird with a wobble plate instead of crankshaft like e-rex😅
Even thou it is not too much power, the VTEC manage to increase it by over 20%. That's really good!
I feel like the valve activating the VTEC is limiting the power. Since it requires back pressure to activate the valve, the engine is basically fighting against that, which means its losing power. Try measuring without the self-activating vtec through the exhaust and activating the vtec manually to see if there's a power increase.
So this is pretty awesome, but again, it would actually be a good idea to actually add counter weights on the crank shaft to help reduce vibration
try and add counterweights to the crankshaft, that might fix the problem with the crankshaft bending
Something that could greatly increase the power, and reliability is desmodromic valves. I think part of why it was losing power was because of spring fatigue and valve float, both of which would be fixed by desmodromic valves, another is by giving the engine Aluminum Can Cylinder Liners. Instead of two abrasive Prints working down the outer layers of each other, friction could be reduced by the aluminum from the walls of a soda can.
or cutting pieces of metal pipe and inserting it inside of the block like sleeves are done, then adding O-ring or multiple O-rings to the piston (and little lubrication ofc) :)
@@AaroKo Yah, I think Reducing friction and adding seals in the block, and increasing control over the valves are the main way to gain power as of now
@@crazycat7760 yes indeed :)
(*PLEASE READ*) A small suggestion to make to exhaust sound cooler squeeze the middle and it will sound like a F1 car (poke small holes at the end with a thumbtack for better airflow and quality)
Graphite Powder? Good. Graphite powder AND grease? Cutting fluid! Oops!
As for helping make a stronger crank, try making an eccentric sheave rather than a classic crank. You'll have more friction and more bottom end mass, but it'll run smoother and be stronger. They were often used with steam engines for these reasons.
are you still working on the gasoline engine behind the scenes?
Maybe... :)
I love finding channels right when there about to get big
Awesome video- your delivery of the lines is entertaining making a great combo of comedy and education
Dang I didn’t expect your channel to blow up this much but I think you deserve it
Also, will there be any more videos on the 3D printed combustion engine project?
There might be :)
i love the explanation and the math behind it.
also clicking noise every now and then in the videos audio?
Have you thought about using carbon fiber filaments?
Not really, none of my printers are compatible with carbon fiber. That, and I haven't felt the need too
The method I'm using to make the "3d printed part" stronger is embedding a bolt inside that parts. Make a hole in the model and just tread a metal bolt in.
Funny ✅
Informative ✅

You need a flywheel on the motor aswell it will raise the torque and power
Bad ass. I've been subbed for 2 years. It's super cool seeing your Channel grow.
Thank you for the support!
you should use the integza way of measuring torque: tie a banana to a rope and see how fast it can pull.
I need my own schtick, like a demon core maybe idk
