Running Lego Engines with Air 

Check out more engine experiments: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IUoZbKFbJo4.html

With each video we are getting closer to having a lego rocket sent to space.

the fact that he's getting the engines to vibrate and behave, even slightly sound like their real life counterparts is astonishing

I love that even lego air engines can suffer from incorrect timing case in point with the V6

I don't know what I am more envious of... your Lego collection, or the inquisitive nature of your cats

Love that subtle "like and subscribe figure". Needless to say, i did.

3:35 I love how it went from 'sad and struggling piston' to 'mid 20th century German belt-fed machinegun'. It really sounds terrifyingly like one, and i love every second of it. The engine is cool too i guess. ;)

As a machine mechanic, i got very impressed with the complexity and the sound is nice. Amazing work there.

nice video bro

As a mechanic, I can almost smell exhaust fumes if I listen to this with my eyes close. Amazing work

As someone who's done a lot of work with steam engines, I am in awe of your air powered motors. I had no idea legos had come so far! The radial engine is especially impressive.

I loved my legos 3 decades ago. Now, I'm watching someone use legos for engineering demonstration, as well as occasionally 3D printing their own pieces. Seems like a solid hobby.

The sheer commitment to experimentation, refinement and then scaling it up to the limits and beyond ---- astounding work. Bravo.

I love the fact that no matter what the format or fuel is, engines will always have the same kind of sounds when they operate.

I like how the engines sound like their vehicle counterparts except with alot less 'bass'

man the sound of these engines even in plastic form are music to my ears, i can keep listening to them all day

One of the best LEGO models for explaining the Hydraulic Engineering!

This video has everything. Extreme serial escalation, fully lubricated modded parts, decent mechanical principle teaching moments, immaculate build sequences, totally unhinged (heh) non 90 degree designs, and a radial engine that I was terrified was going to be a wankel, somehow. The car module? The *skid marks*??? Sublime! Animations! Pieces breaking! This is like the epic film genre of Lego builds.

I love how each engine, despite being air powered Lego, maintains a similar sound to its real-life gas/diesel counterpart.

It's amazing the creativity one can have. It becomes so much simpler when presented, but before the video I wouldn't have thought how I'd create engines from legos.

My Favorite toy as a kid was the "Air Blaster" buggy. My brother and I would put a light dusting of sand on a concrete driveway and race them. Straight out drag racing or you could set the steering angle and race speedway, lol. Ahhh the 80's.

The engineering is obviously impressive but I'm also always jealous of the parts bins these guys must have, and always in such uniform colors.

i love how this guy always just casually makes an engine of some sorts out of Legos and somehow it seems normal

This is absolutely incredible! Hats off to you, sir. What a treat to watch.

This is pure engine engineering. Congrats!!

It's a pity that LEGO does not provide us with sets like this. This is a perfect Technic set.

A parts list would make this truly amazing! Great work!

This looks amazing.

I really enjoyed how similar the harmonics of each Lego engine are to their corresponding real life engine. Great stuff.

When I was young I tried to do a science experiment that would make an engine that runs off of air. I was told it wasn’t possible. I believed that. Thank you for doing this. 👍🏼

Very informative video! Also love The editing style.

Also the amount of sound produced here is insane

There are some amazing stuff done with lego but this is definitely the coolest one i've seen so far

The sounds they make are so fascinating. It's intresting how reminicent the sounds are to their real world counter parts

the big round one at the end looked like a plane engine. sooo coooolll

Amazing. I love how I was like "oh, it moves like a V8 !"

I really appreciate the elegance of your constructions. Also in terms of color scheme. And not to forget the cats anyway.

Just waiting for him to build a fission reactor out of lego.

Amazing work! What a fine piece of engineering 🤌

Absolutely brilliant, great job. :)

I like how all of them sounded exactly as a real combustion engine on idle

I think the engines might run more smoothly if you altered the air delivery; instead of having a single air line with a junction branching off for each cylinder, splitting the air evenly (one air tube leading to a t-junction that splits the airflow into 2, then each of those lines splitting into 2 lines, before feeding into each cylinder of the 4-cylinder engine, for example). Though of course that would involve more pipes.

Vielen Dank für dieses tolle Video, mein Sohn und ich haben es uns gemeinsam angesehen und sind von deinen Techniken begeistert! Vielen Dank

It's amazing how close it sounds to a cold diesel start

Amazing how even in lego form, the engine still has its familiar roar.

2:27 really nice visualization of how the starter works

I'm so glad I found your channel. I'll definitely be subscribing for more content

I was really looking forward to the in-line 6 to see how it’s vibration characteristics stacked up

It makes sense that the smaller engines were more powerful/fast, because they had same amount of total air pressure as the radial, but way less friction. I think it’d be super neat to wire it up so that each piston got the same amount of total pressure between engines-that way it could more accurately represent increases in horsepower.

I’ve learned more about mechanical engineering in a 14 minute video about legos than in 12 years of school and I happily enjoyed every second.

Dude literally explained one of the engineering courses with Lego, absolutely genius!

he explained the operation of the engine without saying anything YES AND MORE FROM LEGO!

This is a true demonstration of how our forefathers thought of the first internal combustion engines, I imagine it was a tad bit more primitive. It's amazing that this is capable in the world of LEGO's~ You continue to show us what is becoming possible! Keep up the good work!

Crazy dude, love the engineering behind all of your videos

I actually remember getting one of the very first pneumatic Lego kits as a kid, back when technic was still pretty new. We didn't have a huge amount of money but my parents really encouraged my Lego hobby wherever possible. This among many other constructive interests and a level of parental guidance that I am extremely thankful for lead me to become the engineer I am today!

bro your videos are so relaxing and interesting that its amazing to see how far Lego has come

The amount of work he puts into this is incredible. Looking at this makes me think air powered cars could be possible, just that it will take a while for it to be a real thing.

The absolutely humongous difference in unlubed vs. lubed is outstanding my jaw dropped with anticipation as to what a complete one will look like

This guy... I'm just happy my level of knowledge is enough to at least hook up a simple pneumatic system 😅

I discovered this guy in 2020 and he made it sooo much better

Wow brick technology you're content is really interesting keep up the good 💯 work

Rating them purely on sound, the V6 sounded magnificent 🤌

This is some next-level stuff. The fact that Lego manages to hold up under all of that tension and rapid movement is nuts - the V8 and radial engines both look like they're actively trying to break into pieces. I also like the subtle color-coding of each engine so it's easy to tell them apart :) I found your channel a few weeks back and have been watching since. It's awesome how you recreate so many real-world mechanics using simple lego, without any crazy modifications. Your cats are also adorable lol

13:24 sounds exactly like my 6.7 powerstroke idling

Absolutely amazing videos. So much fun to watch them. I just discovered your channel.

Just think how Lego could help to teach and inspire entire generations or engineers and mechanics if they made these as sets for kids to learn from.

Okay, that radial engine is totally insane :D

man you are a genius i love your content

My gosh, they sound like car engines when you slow down the audio, which reminded me that “well yeah this is how car engines work except the expansions and contractions are provided by timed explosions instead of timed pulses of air” This is a remarkable explanation of engine types and advantages! And beautiful engineering!

The straight 4 in the montage sound like a 1,9 TDI. Truly magnificent.

Definitely one of the most amazing and cool things about this is how industrial it sounds. All coming from some plastic pieces moving and working together, its truly impressive.

One of my favourite lego videos of all time.

Wow the improvement after the modification of the cylinder! Just goes to show that everything's better with a bit of lube

The concept is so cool. You manage to create a real engine with Lego extremely realistic. Just another incredible build, well done 👍

3:07 BOYS WE MADE A MACHINE GUN

I think its the best lego video I have ever seen.❤

Well done. You sir have earned my RU-vid notification bell 🔔

Just amazing! Tuning all the pistons together must have been a pain

this man's hella underrated

God, how I love the roar of the engine!

This is, by far, the most impressive lego creation I've ever seen

I wish I could take this channel back in time to the 90's, it would have made my youthful brain implode. After years of learning about engines through owning and servicing vehicles, this still taught me several new things, most especially that you can hear how many cylinders an engine has from the syncopation. Thanks!

Great video, i love it. Keep it up. Idk, but for me it sounds like the diesel version of all the configuration

Wow! Using the gas expelled by the previous cylinder as input for the next cylinder is genius!

This is something that should be implemented in ALL public grade schools. The way this could be taught to kids is nuts. I grew up on k'nex which I contribute my thought process and how I figure out things purely thanks to the things I learned working with k'nex. If more kids could learn through this would be huge. Teaches just how mechanically things work, which can be used towards sooooo many things in life.

You should build some vacuum engines out of lego, really cool stuff actually. You run them with a vacuum cleaner, they sound like real engines!

Still can't believe how these sound like REAL truck engines. It's insane!

I can watch this all night

Even at lego scale, the sound of a V6 is incredible. Amazing video!

Quick Q&A: Q: Where do you get all these parts? A: I buy them individually on bricklink.com Q: Why do we not use air engines in cars? A: Compressed air is not free, it requires a compressor running on electricity, petrol, etc… Storing enough compressed air in a vehicle is not easy, the problem with short reach would be worse than with current electric vehicles. Find more info here: en.wikipedia.org/wiki/Compressed-air_vehicle Q: Isn’t this the same principle as a steam engine? A: Yes, just with compressed air instead of steam. Q: Why does the V8 have this weird angle? It is the only way to distribute 8 powerstrokes evenly across 1 revolution. The crankshaft angles divide the circle by 4 and the weird v- angle divides it again by 2. I hope it makes sense, it is hard to explain. The goal is to have each cylinder fire after ⅛ out of 1 revolution. Q: Why is there no inline 6? A: I ask myself the same question… no seriously. This video took so much time to make… I would have loved to make an i6, V12 or even an R9, but I can’t for time reasons. Q: Why is there no boxer? A: Compressed air engines work differently to regular combustion engines. The configuration of an air engine is the result of crankshaft angle limitations. Like described above, the goal is to distribute powerstrokes evenly on one revolution. A boxer would not help to achieve this since 2 cylinders would work on the same powerstroke. A boxer 8 would be the same as just making an inline 8 cylinder engine with 2 cylinders per crank pin. But 2 out of 12 cylinders from the R12 engine are basically a boxer. Q: Are there instructions or sets like this available? A: I do not sell instructions as of now, but there is a great shop that provides engine kits with parts and instructions that are similar to the ones in the video: greengeckoworkshop.com

Its always interesting to see pneumatic machines.

I hope you used a fair amount of lubricants because such speed and force will sure wear those pieces within minutes. Very impressive use of the cylinders!

Stumbled across your channel yesterday and binged all of your videos. You basically are the Primitive Technology of LEGO. Just quiet professionalism, engineering, patience, brilliant editing and creative genius. I have no idea how you managed to reach sublime standards like this from the get go, but I find that I do not really care all too much and simply long for more.

This is one of the coolest Lego builds I have ever seen! This would be perfect to show an automotive engineering class!

3:16 attach that to a table and make it stronger then connect it to a computer so everytime you shoot you can feel the recoil. XTRA REALISTIC

It’s cool that every engine has unique sounds!

One of the most interesting LEGO videos I've ever seen. Well done.

I love how the 4 cylinder sounded just like a shipboard diesel engine. Well done!

Didn‘t laugh so much in a long time, thanks! 😂

that was too cute when you pointed the air tub on your cat❤
