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! Also, that running in the 90s jumpscare had me rolling! 🤣

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.

[@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.

[@Wilma5532]

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.

[@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.

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

Man wotta load of work ❤

[@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]

@@Leon_Strauss That can only take speed into account and not load. If it was that simple they would have been doing it in the 1930's

[@Leon_Strauss]

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

[@fransdebruijn6763]

@@Leon_Strauss If the engine was running at a constant load that approach may work however engines usually throttle with dynamic loads. The cam phasing is usually controlled with a multidimensional map by the engine management computer for this reason.

[@garbageman3992]

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.
