It has come to my attention that it was in fact not an LED, whoops

Gosh, the editing, pacing, humour... These were some of the most enjoyable 12 minutes of my life!

You are very underrated. You have good editing, upload schedule, and are smarter than most engineers. It would be cool if you found an engine that works, and 3d print it out of metal. I would also like to see one scaled up and used in a small vehicle, like a dirtbike, four wheeler, or gokart. Edit: Just for clarification, I meant the gas engine that he built. The air one would probably not work as well as you would have to put a heavy compressor on the vehicle or purchase a really long compressor cord which would lose all of its pressure by the time it reaches the engine.

I know it wasn't just my idea, but I know I mentioned it so I'ma say thanks :)

That is not an LED, that is an incandescent bulb from old christmas tree lights with a "fail safe" feature, namely when the filament cuts off the "arms" widen and short out since there is a coil at the bottom of the light bulb. Have a look, maybe it is already blown. BTW they were 12V each back then.

I was definitely not expecting any of the jokes in the video, I even jumped when the eyes in the dark caught me off guard. Incredible video and intelligent humor. Keep doing videos like this!!

You should try using PA6 GF30. It's really resistant plastic (fuel, oil, friction, and most importantly, temperature). it's similar to the stuff they use to make intake manifolds nowadays. Glass fiber reinforced.

I'm not a 100% sure, but that looks more like one of those low voltage bulbs instead of an LED. Try adding a variable resister to the drill motor leads, this should allow you to vary the load, allowing you to demo the effect VTEC has. Awesome video as always! Also, that running in the 90s jumpscare had me rolling! 🤣

I have a few more ideas for variable valve timing: 1. I've seen it in a lego pneumatic engine video, where the whole valve control assembly was tilted relative to the whole engine. 2. Using a differential, you can have shaft input on one of the three sides, output on the other and adjust the timing by twisting the third (which would stay stationary most of the time). I guess this idea can also be applied to planetary gearboxes.

"The belt saw something it wanted" honestly is the funniest thing this week, the jokes in this video where top class, and the engine was awesome

I'm absolutely not into engines, but your videos are so entertaining and I couldn't stop watching them. Very nice editing, humour and still very teachable. You also never complain about how long it takes to do stuff behind the scenes - printing and designing parts, assembling, testing, fixing, filming, filming again, commenting, cutting... I know how much time goes into that and I just want you to know I appreciate it. Hope you continue dude, big thumbs up!

I love how every video you release gets more and more refined and ambitious! There aren't taht many people (none as far as I know) that would take up making a plastic engine, let alone one with VVT! Can't wait to see what you were teasing at the beginning!

love the aggressive chopping it sounds so powerful

resin 3d printing has to be the answer to your combustion engine melting, and you can get them MUCH MUCH MUCH cheaper than a metal 3d printer, and is only slightly more expensive than the ender 3! good luck! (brilliant video btw)

I am enjoying the commentary and your ability to ad lib as you go, and show your mistakes, you earned a follower keep up the good work.

I love your content my guy. You take 3d printing to its limits and it’s guys like you that help create great things. Keep up the good work man.

Clever design on the vvt phase adjuster. Nicely done.

This channel is unreasonably entertaining and generally interesting, and we're literally watching the production getting REALLY good every video. Why don't you have more subscribers!!!???

great video, keep up the good work.

the slowmotion part goes incredible hard, amazing

Absolutely awesome video bit you spoke over every time you pressed the vvt button so didn't get to hear the change in revs, super interesting content, live the build videos, i can't get closer to your 3d printing quality

I just checked your channel to see if I've missed a new video 10 minutes before you posted this. Great timing!

Discovering your channel on this video, Very interesting, thanks for your work! Your design makes a very educational support for VVT valves !

an inline 2 cylinder with a 180° offset might help with the vibration by providing an opposite force, canceling out the force of the piston. or build a balancing shaft. either way the vibrations are definitely causing issues and likely led to some of the failures because of the repeated stresses. also the stopcock should be isolated from the inlet, as the big brass valve is putting quite a bit of strain on the inlet, which is what likely let to the intake cracking.

You should do the thing where you bake the parts in fine powder to strengthen the plastic. This may help with some of your part failures, though it would mean re-finishing some of the surfaces.

You are a genius, briliant humor and fantastic engineering. I dont know how I haven't see your channel before

Video is 🔥 I love your stuff brother! I love your applications of 3D printing!

This video was hilarious, and also super cool engine design. Looking forward to seeing this video hit 1M!

MAN, please, do not sweat about running or not, the procedure of your approach to the problems is more than enough and fascinating to see, really, really cool. What is extremely complicated was given on a plate a baby can eat it up, bad metaphor, but you get it. Make more of this content. Subbed, engineering and designing takes time, its not university. We are here for that said process, not results.

Love your stuff, and love the clever VVT cam gear!

The belt saw something it needed 😂 you are hilarious, love your videos hope to see a nother one soon

Your content is great. Ups and downs, failures and successes, and humor strewn about. I really hope you become successful with the KZfaq thing

Man video quality improved so much. Keep at it your doing amazing stuff

You seriously have the videography skills of much larger youtubers. I wouldn’t be surprised if this channel blows up soon

maan you're doing some god's work, and I mean it! your videos are very obviously progressing in quality of everything really, the storytelling, the editing, the humor.. glad to see you improving AND making interesting things I've always been fascinated about myself

This man went from a Subaru EJ25 AVCS gear style design to a 2jz. I love your thinking, it somehow makes my brain be at ease and it just makes sense. Thank you for providing me with this 3d printed form of entertainment 🤧

"The belt saw a thing that it wanted" got me so good! That fail montage was gorgeous!

Videos always are worth the wait RIP AIR ENGINE but variable valve timing finna go crazy on the combustion project

the car edit thing scared the crap out of me lmao. nice video! you are up there on my top 10 most favorite content creators to watch!

Awesome! Please continue uploading, your channel is very underrated.

The fact that the car flying through the air caught me off guard as much as it did pisses me off😂😂😂 great video!!! Kerp up the good work bro!

You could make a variable timing using a differential or planetary gears. In a differential, if you use one output as input and the other as output, moving the input will change the "phase" of the output relative to the input. Extrapolate to planetary and you'll get it

dude let's go, hyped for the upload. good work

this is incredible. So cool!!

this guy combined integza and IDAT and earned himself a subscriber. cheers

10:17 "the belt saw something it wanted" got me.

As someone who’s worked on 2JZGE engines that was very cool to see it duplicated on your model. I always had GE NON-VVTI motors so I never understood the system all that well. Cool vid

Hahah you calling that bulb an LED was the highlight of my week

Thoroughly entertaining video, keep it up!

Very good. I need to try something like this!

You do everything I wanted to see when people started 3D printing little airhogs-esque engines

Your so underrated man. How are you not more popular

Hey man just stumbled across to your channel wow I can't believe only 50000 subscribers keep it up man I love all the educational KZfaq's you have a niche I like your style don't stop press forward

I WAS WAITING FO TTHIS FOR SO LONG!

This guy makes the coolest mostly functional engines

Broo you inspired mee for it and also confident for my work of making air engine

That engine slo-mo video is what a migraine feels like.

The calm, collected chaos is top notch. Also, you did us dirty with not only one, but two, jumpscares.

Man with every video the quality just keeps improving, and not just the actual engine. The editing, the jokes, the storytelling.. way to go man!

Your humor tickles me in weird places. But also the home brew VVT is dope.

That's awesome I love stuff like that

NICE WORK

your videos have gotten soo good. your editing quality is awesome, good upload schedule. very interesting videos. love it all! also an interesting Idea is to use an Arduino and hall effect sensor to measure rpm and use a servo to allow the Arduino to adjust the valve timing for the most power at any rpm. this is difficult because it requires dyno tuning to determine the tuning which I cant help you with because I haven't gotten a mini dyno working properly either but even without a dyno a lot of trial and error can result a a decent power curve. I do some air engines and I have an Arduino with a hall effect sensor (and sometimes a coil and magnet) to measure rpm and a servo to adjust intake pressure and it works great, extremely simple to code and easily keeps up with even my 7k rpm engines. My engines are small so i cannot implement a vvt system, iv been trying to make that same style vvt system smaller than 1cm for a while so instead I have permanently set very advanced intake timing and a servo controlled intake pressure to suit the rpm. it results in power similarly steep to a 2 stroke but the Arduino system works flawlessly. plus there are plenty of other benefits of an ecu as you can really do anything you want.

Amazing video!

Vehemently valuable variable Valve-timing

I recommend changing the belt situation as in changing to a rubber belt and adding more gears including a rolling gear to help keep the belt under proper tension and prevent it from flying off

I had to rewatch the eyes in the shed part a few times! Too funny to me for some reason 😂

this is truly amazing... I know its not looking too good, you NEED to work on trying to add vvt to that other engine!

Really cool design. Maybe you could use a centrifugal actuator for automatic valve timing, that would advance the timing the higher the rpm is.

Great video! Love your work! too bad about the light bulb ... Im happy to see you now know the difference :-)

Great video!

8:53 The background music perfectly syncs with the sound of the piston going up and down

underrated creator right here

the dry comedy alone is enough for me to subscribe

GREAT VIDEO DUDE

"The flywheel kept rolling away, then the belt saw something it wanted" i laughed soo hard at that! Great video man!

haha i love your vids, i love the touches of humor too, "the belt saw something it wanted" XDDD

I just came up with a way to implement variable timing in a possibly simpler way by modifying the tensioner. Instead of tensioning only one side, it has to be a dual-design, tensioning both sides of the belt (like pinching the belt before and after the wheel). Once tensioned, the offset can easily change by moving the tensioning assembly to either side and therefore shortening the belt on one side, and lengthening it on the other side, thus effectively changing the offset.

Man wotta load of work ❤

Loved the video as always, keep innovating! Also, my comment made the video 🥳

Nice engine i wish i had 3d printer

That flaming laptop bit was golden! 😂 Your effort is appreciated! Edit: Nevermind. The whole video is golden! 😂

This is super interesting to me especially since my car has a V6 with VVT-i

"the belt saw something it wanted" that shit sent me into a laughing fit hahahahha

finally, another episode, but you should add some oil so the engine doesn't blow up

Pneumatic engine with a turbo that uses the exhaust air to spin a turbine to then push more air into the intake, idc if its not effective or efficient, the world needs it right now.

Dude i just fucking love your videos i hope to see more in the future!

This guy is very impressive

Bro is going to explode in fame in the near future

Yo I need a 3d printer I wanna 3d print this this is amazing bro omg ur my only source of satisfaction on yt ❤️😁

There are a lot of cool, innovative VVT designs in the motorcycle world. You should try some of those out!

Here is a comment for the algorithm to help you blow up which is inevitable. You are doing great! Cheers!

It wouldn't quite match up with combustion engine technologies, but you could set up a lever based continuously variable cutoff. Much like the reversing gear on a steam locomotive. Which would also work if you made it a double acting piston.

You've made a Toyota BEAMS in 3D-print, impressive; most impressive.

It seems plausible that one could make a centrifugal mechanism that will automatically depress the spline gear to advance the timing. Depending on the spring strength, one could control when the engine will begin to change timing, similar to how the mechanical advance works in an automotive distributor. One design idea would borrow from a mower engine flyweight governor. The center pushrod would already move in the correct direction and depress the spline gear.

"World's dullest pipe cutters (tm)" - oi, I got the same ones! Well, my neighbor does anyways xD 4:49 am I the only one that's terrified (for a short moment) when "Running in the 90's" suddenly starts playing? 10:15 "the belt saw something it wanted" - I love your style of editing

I can’t wait until he reaches 100k subs

You could've also changed the belt tensioner. 1 auto-tensioner and 1 manual adjusting tensioner on the opposed moving side. Very easy and reliable

This was nice

You are the most canadian man I have ever seen
