Wow you outdid yourself with this one Noah! The scale of your models makes them run with a facinating composure and it gracefully displays how insanely clever these contraptions actually are. Needless to say you've left us wanting more haha!
Thank you Lelle. Really just a test engine thrown together with spare parts I had sitting around. It all came together. I'm glad you like it. I still have the screenshots of the realistic single-cylinder you made on Studio.
Two stroke engines don't usually have valves, they just have holes in the cylinder that get covered by the piston when it goes up or down. But I suppose adding the valvetrain makes it more interesting and it wouldn't make sense to have a four stroke air-powered engine.
Wow, thanks so much for your thoughtful comment. I think of this engine as a two stroke engine disguised as a four stroke. It has the valvetrain of a four stroke that we all know and love (or is that just me? 😂) but to run well on airflow is uses a two stroke cycle. I'd like to see more LEGO engines that are two stroke air engines disguised as *two* stroke IC engines! Do you build? Thanks again for sharing the knowledge in the comment section!
You know, you're probably right that this engine would like that. It just felt like this flywheel was already so much with the train weights that it was hard to wrap my mind around even more weight until you said that haha
Thanks I appreciate it 😁 These gears and links were released in the 1970s and haven't been in production since 1981. The BrickLink part numbers are bb0076 for the link and g21 for the gear.
Sorry I accidentally replied to the wrong comment there 😝 The reply for you was - good eye! You're the first person to comment about that. I have a YT short called "Life-sized LEGO Engine" that shows the bearings more up close if that helps.
@@engine1ear151 no problem haha ^^ Yes I already saw the video. I find your creation truly fascinating lol. You use some master Building techniques I see. Like the torque wrench for example. One is very limited with the shapes of the lego bricks that are available, I know how much time and effort it takes to find and arrange the lego pieces to create the mechanism in such a small space. At first I thought, the torque wrench is a non working display model lol. I am very curious, with what you come up next. The engine you made is sick, never seen before.
@@guentherjuergen7304 your feedback really means a lot coming from an experienced LEGO gun builder. Your LLMG 3.0 looks like it also took copious amounts of time and effort. Had it not been for the engine building experience I had the wrench may not have come together. The test mule engine is spare parts thrown together from ideas accumulated over the course of years. I'm really impressed with how you capture both the form and function of your subject material. A kindred spirit!
@@engine1ear151 Many thanks m8! Yeah I put a lot of time into it lol, for my new project I also need to find some spare time^^ Okay so it is the best of your ideas basically. It's the same for me, you learn from the different iterations. You dont fail to impress me either haha:D
Thanks for asking! Yeah that's basically what it cam down to. I wanted to make a camshaft that matched the scale of the piston diameter and the diameters of the crankshaft journals proportionally. I stole that cam lobe from an engine MOC I saw on LEGO ideas!
A couple people have measured the power of their LEGO vacuum engines and it's usually less than 5 Watts or 0.006hp haha. There are a few impressive applications of LVE powered vehicles out there though. This particular one is not built for power but for realism.
That’s awesome! Just wondering though, why do you need to have a non-lego cylinder sleeve? Also, I don’t think it matters that much for aesthetic reasons but I really do think it would run a lot better with a cam-profile that has a longer duration and less lift. Very realistic!
Thanks for the thoughtful comment. It has a non-LEGO cylinder sleeve because I tested building the cylinder out of LEGO and there was too much friction for it to run even after break-in. And you nailed it with the cam lobes - this was the first iteration for this engine, made to look realistic and inspired by a LEGO Ideas "working four cylinder engine." When it ran with them, I was delighted and didn't want to change them :D
could u make the gear ratio a 2:1 instead of 1:1 cuz i think it would be even moe realistic but its very realistic and i love this build keep up the good work wit the channel man much love @@engine1ear151
@@MatthewBarnes-2023, I like the way you think. Yes, it would add points for realism to have a 2:1 gear ratio. Now let's follow that proposition through to it's conclusion. It would mean we have each valve opening every TWO crank rotations now instead of every ONE. That would leave a full crankshaft rotation (piston upstroke and downstroke) in which the air only gets in or out via gaps between bricks. This engine doesn't have amazing depression (sealing) but it has enough that the upstroke and downstroke mentioned above in the 2:1 ratio scenario would cause a pumping loss that the inertia of the flywheel would simply not overcome. Another way of expressing it is that 2:1 ratio would be making this engine a four-stroke engine, but there is no power stroke from combustion so the stroke normally known as the power stroke in internal combustion would only result in a mechanical loss. I could set up the engine in a 2:1 configuration to show it off with the extra realism, but without a significantly more powerful power stroke, or a design more resembling the four-stroke cycle, it wouldn't run. So I opted for it to run. I'd love to know any ideas you or anyone else has for solving the 2:1 ratio design problem on a LEGO air-powered engine. I've had some myself in the past and haven't yet tested them. Thanks for the comment :D
I appreciate you asking. I've noted your request and I'll keep tabs on if other people like this comment. Right now I'm working on some other projects :)
I appreciate the advice. This engine was more about crossing over the line - if it ran at all I was happy haha. It definitely has benefited from some optimization since then!
wow! a round piston vacuum engine that runs good! that is some excellent work you have done!
Thank you :D
Let’s gooooo! It sounds like a proper single cylinder

A very underated channel! hope you can get more peices for a 2 cylinder one :)
Thanks for saying so and yes I hope so too!
The best vacuum engine I have ever seen, this is incredible.
Wow, that means a lot, thank you. Do you build them yourself?
Man this is awesome keep up the good work.
Appreciate it :)
That's really great!!
5:18 put the video on 2x speed and listen
This is amazing I make Lego vacuum engines but I never knew they could be so realistic!! You got a sub!
Thanks! I had my doubts that it would run at this scale but this one proved the concept 😁 Perhaps this has given you some ideas?
Pls add a bigger flywheel, i can see the engine strugling to stay alive xD
You know, you're probably right that this engine would like that. It just felt like this flywheel was already so much with the train weights that it was hard to wrap my mind around even more weight until you said that haha
@@engine1ear151 u can see it almost completely stopping every rotation, whych is a sign of too little momentum in the flywheel
@@dominikvarholik7519 Yeah that and very little power hahaha
it's a superb piece of engineering work...congratulations...have you considered making a multi-cylinder version of this engine?
This is the single coolest lve i have ever seen
Thank you so much for saying so :D
that things massive
Almost the bore size of a briggs :)
Holy hell dude this is incredible! Looks like it could use a bit bigger flywheel though.
Thanks so much! I'm curious why you think so. Did you notice that I have some special parts in the flywheel for weight? 😋
awesome build man
Thanks 🙏
Brilliant, just brilliant. Definitely need to do instructions please.
I think I'll get there eventually, but for now I have some other projects I'm working on 😁
Woww this is quite amazing 🤩👍
Thanks so much 😀
Wow he’s back wow
we are the student you met at kics this very fun to see and build when we are bored !! 😁😁😁 Keep up the hardwork!!!
It was great to meet you! Enjoy designing and learning :D

Thanks bro 💪
your engines are absolutely awesome! i just have one question, what kind of chain are you using as timing chain?
Thanks I appreciate it 😁 These gears and links were released in the 1970s and haven't been in production since 1981. The BrickLink part numbers are bb0076 for the link and g21 for the gear.
just wow, you made an actual bearing out of lego, thats why it runs so smoothly. But I cant see which parts you used for it exactly
Nah I'll let the intern do that

interesting cam lobe design. was the lego part #6575 too small for your design?

i know its lego and its powered by air but how much horsepower would this make?

Wow at that scale we could make a real V8 you know
Do you know any V8s with that size piston?
@@engine1ear151 no no none at all I haven’t seen a single LVE this size ever. This is basically life size
Yeah so I was thinking, in real life, is there a V8 that has a piston this size?
@@engine1ear151 there are definetly v8 engines with this size or even bigger pistons out there
Most of them quite a bit bigger...
Please make a tutorial that would be amazing
In the meantime, I shared more images of this engine on Discord if you would like some help trying to build your own.
