Variable Valve Timing Air Engine

In this video, I explore how Variable Valve timing works and how It can be used on an miniature engine such as this. Homemade mini air engines like this can benefit from VVT since it can alter the behavior of the engine.
I used 3d printing in order to design and make this air-powered engine.

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.

[@gabecimoch2160]

You should check out this air powered locomotive. It's really cool although it is basically a steam engine that doesn't use steam. Although I would love to see a steam engine build for making a generator. kzbin.info/www/bejne/qKallK2uadGrgtU&pp=ygUWYWlyIHBvd2VyZWQgbG9jb21vdGl2ZQ%3D%3D

[@paulroberto2286]

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!

[@JTCF]

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.

[@toma.cnc1]

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.

[@fabianreis3946]

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)

[@Sonriah4145]

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.

[@AlexLC409]

great video, keep up the good work.

[@CamdenBowen]

Thank you Testicle Inspector

[@Reverend_Salem]

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.

[@falin9557]

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

[@SG-yq7fm]

That’s actually what I was expecting him to do, though with all the moving parts and small gears, it’s just another point of failure. Probably best to stay simple

[@evanchapmanfanman]

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.

[@Leon_Strauss]

i think a centrifugal governor would work

@@fransdebruijn6763 The load would reduce the speed and the timing would then be automatically adjusted, right?

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

[@clemensruis]

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.

Don't forget you could also make the vvt system run off of centrifical force the same way a 4 wheeler clutch would work. Ball bearings could be placed with springs, when the centrifical force exceededs the spring tension it could grab the gear and turn on vvt!
