build a v12 in a sports car
Sensational
Absolutely pushing the limits to what you can do with lego
try V8 F1 car
cool but how are you so good at this
With each video we are getting closer to having a lego rocket sent to space.
I’ll do it, just give me 6 years.
*foreshadowing*
You got the right idea
Now we gotta make Lego Elon Musk
Or making an actual working full sized car…
i want to see thise happen !!!
I like how the engines sound like their vehicle counterparts except with alot less 'bass'
That is what an exhaust is for. :)
same it just sounds like a real engine it very weird though
@@BurningGodzillaJr yeah I was about to say that the i3 sounded a lot like our irl car
I wanted to hear an i6 for this reason but I guess the i6 design hit the cutting room floor
why are you putting fish in your engine
I don't know what I am more envious of... your Lego collection, or the inquisitive nature of your cats
I love that even lego air engines can suffer from incorrect timing case in point with the V6
hehe i didnt notice that
It makes me wonder if it would be more effect to have less pistons and bigger pistons.
the fact that he's getting the engines to vibrate and behave, even slightly sound like their real life counterparts is astonishing
I certainly could hear my old caddie when the v8 was running.
well to be fair what he is making is a real life engine just in legos. Just with air instead
Cause there's no difference between the sound of air being pumped and literal explosions
@Russell Phelan Subaru boxer sound is mostly due to unequal length headers
Goes to show just how much force actual engines apply.
As a mechanic, I can almost smell exhaust fumes if I listen to this with my eyes close. Amazing work
You right
lol
I'm a plane engineer, and I can confirm we can make a jet and fly mach 2 with legos
@@talonlol_easy right
That's... actually bad...
As a machine mechanic, i got very impressed with the complexity and the sound is nice. Amazing work there.

@Quinn Dehner pointless comment
I didn't.
Although that's only because I already had, this video is great and I was already subbed.
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.
And a Cat, dont forget the cat!
remember, the skid marks were NOT from the engine torque overcoming the grip, it was from the mass of the car overcoming the grip
@@jody024 TWO cats!
I love me a good radial engine
Someone made a Lego wankel engine that runs on compressed air.
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.
Especially the V6 in this video would make me believe that there was an actual car if I had to close my eyes.
Noise is always a byproduct and therefore inefficiency. Electric motors being silent tells a lot about their efficiency.

@@RCP-1136 it's sounds nice tho
The sound from the dual cylinder reminded me of Sebulba's podracer from Star Wars Episode 1. That chug chug chug chug is a sound I'll remember for life.
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.
These engine designs have been around for years, I like to use legos to build rc things, like submarines or cars. Or even ships.
Then you get the "Okay bye" I was frustrated. I'm old and this is awesome. Radials have no purpose in something of this scale unless the plan on Lego flying at 15,000+ feet
@@RevengeAvenger Now THAT I would like to see!
@@RevengeAvenger Hello I have a question. Why do radial engines have no purpose except in high altitudes? I just did a bit of reading on V engines and why we use them but I still don't fully understand why we wouldn't use engines of another design, like a Y or X. Couldn't someone technically engineer a radial engine with two 12-piston engines firing at opposing times to counteract the forces? I'm not questioning the fact that we use V engines in cars for a purpose, I just want to understand why they are the best option.
I think they're getting more sophisticated because you can 3D print the legos. That's what i think hmm
man the sound of these engines even in plastic form are music to my ears, i can keep listening to them all day
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.
I love how each engine, despite being air powered Lego, maintains a similar sound to its real-life gas/diesel counterpart.
the 4 cyl is so similar to a 4 cyl modern diesel engine
i was about to comment the same thing
Tbh, these are more akin to Steam engines, being single stroke engines.
afaik the tone a engine produces mainly come from the cylinders firing order
@@Tonyx.yt. I thought the same
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. ;)

Neat
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 know. If I did a channel like this, there'd be Ninjago lime green and neon orange in the mix.
he even reinstated how expensive some of these builds are
How does one even go about obtaining these sort of parts without collecting 100 unrelated sets and using a handful of pieces from each?
@@cavelord4766 Buying parts seperately from either bricklink or from Lego!
i love how this guy always just casually makes an engine of some sorts out of Legos and somehow it seems normal
It's sounds like an engine
@@BrowncoatInABox HOLY SHIT, The V8 version has the V8 sound to it.
1:37 What's fun about this is this is literally how steam powered/pnumatic systems work. This gives me "the way things work" vibes just without the narration.
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.
It's a pity that LEGO does not provide us with sets like this. This is a perfect Technic set.
They probably want to avoid it blowing up and hurting someone, or somebody missplacing 1 piece, breaking some crucial pieces, then crying on reddit about it
@@jnkara25 eww reddit
One of the accepted lego ideas set is a pneumatic steam engine
@@ghoulbuster1 theres a bunch of people on reddit who are really knowledgeable. i go there sometimes for help with computer issues or even vehicular problems theres a lot of car guys on there who know what theyre talking about. Reddits an awesome place with a bad name
@@SirFiggles I agree, but the bad name has an origin, a painfully real origin. The site has some real problems, which have just led me and many others to abandon the site entirely. You do you though, no doubt there are many good experiences to be had on the site.
A parts list would make this truly amazing! Great work!
I was really looking forward to the in-line 6 to see how it’s vibration characteristics stacked up
I really enjoyed how similar the harmonics of each Lego engine are to their corresponding real life engine. Great stuff.
Not impressed either. But the engine doesnt have to be what it strives to become, especially for wankers saying dumb things. If you dont have the creative mind to make change because youre already supposed to be.... or perhaps you're the epitome of all that behavioral thought shining in.... not even gonna finish that thought. You have fallacies of judgement in others. Passive aggressive tendencies to the point we could all just be waiting on a handful of you & you'd still be doing shit this way. Sideways from sideface. A hater who doesnt want anyone to know it so he plays his inocuous comments snuggled right up next to the best example for a daddy or therapist you could find to play your spoiled bratty part. Probably 75 tho.
Yes! The i3 and i4 both had a nearly perfect diesel idle rattle sound
Me too! The V6 sounded EXACTLY like my old jeep did while it was idling!
the inline 4 sounded exactly like my MGB
Yeah i was thinking the exact same thing, especially when I heard the v8.
The sounds they make are so fascinating. It's intresting how reminicent the sounds are to their real world counter parts
by the 4th cylinder, i was hearing a diesel engine xD
@@xXCursedWorgenXx yep, good old volkswagen golf 1.6 diesel :D
I mean this is literally just plastic machinery made from a standardized system
@@DovaDude That works without esential parts of the standardized process such as combustion, with contributes greatly to the noise
@@agustinnarvaez5251 most of the difference is just volume of exhaust. The lego is still producing exhaust it's just air from the cylinder instead of combustion gases. When you look at it like this it's easy to see where the sound resemblance comes from
This is pure engine engineering. Congrats!!
Looks and sounds like a mini engine, amazing!
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. 👍🏼
All you need is a powerful compressor powered by a battery, but there you’ve got an electric car
It's amazing what small pieces of plastic and air can do. Imagine what could be done with pieces of steel and hydrogen combustion. The energy and technological interests are evident.
@@arcosprey4811 how far can a tank of compressed air get you? On that note, if a tank of compressed air I could get you a reasonable distance. Rather than gas stations, how about compressed air refill stations. . . Idk lol
thats how all steam engines work
@@darkblade51224 dont you pump tyres using compressed air from petrol stations?
I really appreciate the elegance of your constructions. Also in terms of color scheme. And not to forget the cats anyway.
This looks amazing.
the big round one at the end looked like a plane engine. sooo coooolll
There are some amazing stuff done with lego but this is definitely the coolest one i've seen so far
@@eclipsemantis cool either way, even then, the commenter hadn't seen it yet so it doesn't matter that they have been around for a long time.
@@qwertasdf5044 Very true, my original comment was a bit harsh

As a government official I can confirm he's already on a watch list for beginning work on one xD jk
Amazing.
I love how I was like "oh, it moves like a V8 !"
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.
I read an article about a visit to an engine building shop that, in addition to a dyno, has an engine test stand that can just forcefully spin the engine without it actually running (using compression, just no fuel or spark). They also tested just valve trains this way (spinning, no compression). The author was struck by how much of the characteristic running sounds of each engine were still recognizable.
@@dennisferron8847 fascinating!
Here is a similar experiment with firing orders. Notice how the idle sounds near the end. th-cam.com/video/7oOF4lHAM9w/w-d-xo.html
i understand nothing cuz i don't know anything about machinery
Right?! I could hear the rough cam idle as he added load to the |2
I like how all of them sounded exactly as a real combustion engine on idle
Is this because piston strokes don't have a perfect circular motion? Or rather, perfectly constant movement during the stroke?
@@gameseeker6307 This series of development started off in the stage developed by James Watt. What followed were quite similar engineering mistakes, plus their respective solutions (and failures).
Each 'stroke' is a sinusoidal movement. Depending on the properties of the mounting frames, these movements translate into vibrations of which many transform into sounds.
@@frutt5k I want to note: sound is a vibration of many atoms at giving medium, usually happened from external force (example: collision, friction, etc).
Atoms not always vibrated from external force. If the atoms is energetic enough, it will vibrated on itself which we know as "heat". Overtime it lose a vibration for a little along with emitting a photon (mostly infrared).
@@haikalmiftah2529 Thanks for the note. You sounded runk.
Also the amount of sound produced here is insane
God, how I love the roar of the engine!

@@boneman9751 :D
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.
That's actually a good idea! But to correct you, it wouldn't even need more pipes. You just need to connect them different but it would still take the same amount of components. Maybe if you would go even further with optimizing pressure delivery to the valves go as far as building like a box as airtight as possible with as many outlets as you have valves to not constrict the airflow to much. Maybe even add a custom build valve to regulate the speed which has a little more cross section for air to pass but I'm not sure how feasible this would be with Lego to get it as tight as it would need to be. But definitely a cool video with a lot of potential for further development...
yeah or even like for the v8, using one tube for each half
@@scarrax0159 Also i think some kind of flywheel would help make them run smoother.
the limiting factor is generally friction in the valves and pistons
@@nuirueu definitely. In the end this is what flywheels are made for. Would probably also help for the 12 cylinder radial to put another one behind it with half a rotation offset to minimize vibrations. And it would be super cool if you could pull the cylinders further apart and create a hollow axle in the middle kind of like on those fighter planes where they then put an autocannon in the middle. But those are probably just dreams in terms of Lego feasibility...
Amazing work! What a fine piece of engineering 🤌
Wow the improvement after the modification of the cylinder! Just goes to show that everything's better with a bit of lube
2:27 really nice visualization of how the starter works
It's not how it works in actual automotive engines though. Still really cool
Ya, though the starter gear actually slides forward into engagement rather than moves in from the side.
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!
Same experience.
Same, the only difference is probably that lego shifted me towards civil engoneering
I had a similar storyline, and my engineer father kept fostering my love for such things (I had the blue pieces pneumatic set), but to his dismay I went into filmmaking and the arts.
Parenting done correctly! Yet these days your parents would probably be criticised for not letting you "just have fun" with TikTok and alcohol...
@Brad: Yeah, today's parenting has fallen far from what it once was, I've seen a show in which a mother said she raised her child *_gender-neutral_* and always evaded people's questions about what gender the child was!
I can tell ya, I'm thankful not to be that child and pity them (great, now I have to start talking like those freaks too!) for being offspring to such a lunatic! Wouldn't be surprised if 10 years from now I heard about said child having been bullied into suiciding by "normal" kids, tho I'm not sure if I wanna find out what "normal" kids will be like in 10 years.
Whatever the future looks like, I've made a rock solid decision not to have children and expose them to any of the current bullsh!t going on in the western world! I wouldn't wanna be the father of a child who suddenly came home from school and started talking about gender crap or critical race theory bullsh!t! Some countries may have banned all that, but they have other flaws to overcome.
Dude literally explained one of the engineering courses with Lego, absolutely genius!
i seriously LOVE this guys channel no annoying tts or voiceover just PURE video and subtitles
Without really speaking.
I like how the engines sound so realistic.
8:29 - That rocks.. That rocks a _LOT_!
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.
I think compressing the air to do that is the major problem to tackle in that case, takes a lot of energy
Rating them purely on sound, the V6 sounded magnificent 🤌
I was thinking the same thing!
Me too
Sounded oddly throaty like a hemi
My friend: let me introduce you to Formula 1, where the V6s can hit 16,000RPM.
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.
That would be cool to look into!
It's a tradeoff. More cylinders, less RPM, but more torque, so the optimal engine is dependent on your needs/wants.
@@fuery. only true for this case of Pneumatic Cylinders. If the cylinders otherwise had their own dedicated pressure source or if he had used a proper distribution manifold more cylinders would still generate more power albeit not at a linear rate due to friction.
@@aoyuki1409 next vid : Creating lego air distribution manifold :D
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!
It sounds better sped UP!
One of my favourite lego videos of all time.
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

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!
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.
This would be an amazing idea. Like, something of a build and learn set. Say a kid builds a V8/Inline engine. As they build the set and go through the instruction book, there's little boxes that talk about how an engine works and what some of the parts do. Ideas like this would be amazing
@@kyledragonheart3875 This way they could even make specialized switch parts that are more optimized for the task than the existing one.
I think the wear on the switches could run afoul of one of Lego's design rules, but forget about teaching kids, I would buy the V8 model for me.
The concept is so cool. You manage to create a real engine with Lego extremely realistic. Just another incredible build, well done 👍

i agree
Really cool that the engines sound like a real version just less deep

Just amazing! Tuning all the pistons together must have been a pain
It’s amazing to me that the Lego v6 and v8 engines sound so much like their real life counterparts. My car has a V6 and it sounds exactly the same when idling.
I think its the best lego video I have 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!
In the 80's my big Christmas gift was the Expert Builder car with an inline 4 and working clutch shifter. LEGO has come a long way from 1982. I used what I learned to make a working Ferris Wheel. The big tire wheel hubs from the Farm Tractor set were the center connectors for the Ferris Wheel frame.
As someone in their youth my brain is indeed imploding! Videos like these make me want to pursue engineering, sometimes...
I think I've never understood the basics between "I" and "V" all these years. And I think it shows me my mechanic father knew a bit more seat of the pants science than people would think.
Remember that the Lord Jesus Christ died on a cross for you because He loves you so much. He then rose up from the dead three days later
The Ten Commandments are called the moral law, (most of us are lying thieving blasphemous adulterer at heart and deserve hell) you and I broke the law, Jesus paid the fine. That’s what happened on that cross.
By believing that Jesus died on the cross and rose up from the dead 3 days later and not just confessing your sin, but also repenting of all sin you have done and putting all your trust in Him in prayer, He will grant you everlasting life as a free Gift.
It barely sounds any different above 2, but if you tap along with 2, 3, 4, 6, and 8 different fingers at the different RPMs you can really tell the difference.
I discovered this guy in 2020 and he made it sooo much better
man you are a genius i love your content
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!
Even at lego scale, the sound of a V6 is incredible. Amazing video!
Still can't believe how these sound like REAL truck engines. It's insane!
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
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.
im a 06 kid and my elementary school actually taught us a little this way, with lego!
I learnt more structural stuff with lego then mechanical but I still apply my thought process and that to how I think daily!
No way... Math and science is racist to Rihanna's kids.
I loved K'NEX - I built so much cool stuff with it as a kid. An air hockey table, a trebuchet, a repeating crossbow and an automatic full-circuit looping rollercoaster that went all the way around my bed.
I get sometimes frustrated at work if I'm trying to make something, as I know I could make it better out of K'NEX!
Lol you think schools are for education 😂
And that’s precisely why it never will be.
Schools aren’t meant for education; they’re meant for indoctrination.
This is one of the coolest Lego builds I have ever seen! This would be perfect to show an automotive engineering class!

cant wait for this guy to reinvent the universe in lego
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
Someone went one step further and created a fully functional car engine on air with LEGO
How much you want for the v8 one.

Man has an ingenious mind and I guess they will never grow too old for Lego :)
bro your videos are so relaxing and interesting that its amazing to see how far Lego has come
I love how the 4 cylinder sounded just like a shipboard diesel engine. Well done!
This guy...
I'm just happy my level of knowledge is enough to at least hook up a simple pneumatic system 😅
My builts would get your worst rating in a review, it's so complex even I had some Blackouts when cabling :D

It say me i win i price i think is a scam but comfirm pls
🤓
@@BrickTechnology dude this was awesome I wonder how a rotary engine would work with this system?
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!
this man's hella underrated
A Lego pneumatic engine kit like this would be a great tool for showing people all the basics and timing of making an engine run. Instructions for different configurations and detailed visual and written explanation of all the components could definitely supplement the set well!
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.
That primitive tech comparison is spot on!
I didn't know air engines need a catalyser, but i'm glad you added one at 3:42!
Bro that Inline 4 and V6 legit sounds like diesel engines that you’d find in a diesel powered pickup truck.
