I hope you enjoy my compilation of crazy Lego Pneumatic engines. If you want to build your own engine you can find individual Lego Parts on bricklink.com.
To make engines like the ones in the video, you need modified Lego Pneumatic parts. You can buy them here: www.greengeckoworkshop.com/ or modify them yourself. Check out the GreenGeckoWorkshop TH-cam Channel for modification instructions, or get an engine kit with ready made parts and building instructions.
A compressor is required to run these engines. I use a silent Implotex Airbrush compressor: surl.li/gjyvq, but even a bicycle pump with a soda bottle as air tank works well enough for smaller engines.

I LOVE YOUR VIDEOS!!!
Seriously, I´ve watched them all and enjoyed watching every single one, especially because I enjoy LEGO myself.
Always happy when you upload!
hey, I see you made my single cylinder lpe (engine #6) from my other channel, ludicrous brick studio:D
@@bric_dude yes, I added you to the credits. I tried so many engine designs. Sorry that I forgot to mention you. Great design btw.
@@BrickTechnology thank you:) I appreciate it👍
@@BrickTechnology Has #9 been sponsored by Audi?
this guy's gonna end up building a whole rocket ship made out of legos and fly to the moon with it
Honestly I wouldn't be surprised he's a genius
Ha
And I cannot wait until that video comes out!
If we look at the prices of Lego it would cost 100x more than a normal rocket
lol
Something these model engines show really well is how the rotation of an engine isn't constant in it's speed; the crank rotates faster when the crank is at 90degrees to the connecting rod, and slowest when it's perfectly in line with the connecting rod. That's why heavy flywheels are used in a lot of 4 cylinder engines, and why engines with more than 4 cylinders are so smooth.
Not if each piston is offset by 90°.
I tried making lego pneumatic engines when I was much younger, the old single acting cylinders moved much easier and so did the switches although the switches were still too stiff really (also theyre off in the middle). I like the pinched tube idea, Id like to see more of that.
Thank you for inspiring me to build my own model engine!

@Bully Maguire 🅥 thank you :)
It’s amazing seeing the I6 engine’s fixing the firing orders, from an unbalanced to a balanced version, solve vibration completely!
The 120⁰ for the Inline-3 and V6 was easy (albeit still very clever), but the Inline-5... You made a custom 72⁰ component. And here I was thinking that you couldn't get any more devoted and ground-breaking (other than finding a way to mass-produce and sell Lego sets of these while gaining a decent profit). I am forever impressed.
I feel like these engines would be a lot cooler with colored smoke and clear tubes so we can kind of see how they work
They run far too fast to make that help with visibility unfortunately, but that would be cool
The original lego car engine video they made also goes a bit more in-depth on how they work
@@BetaDude40 I've seen that, my thoughts were more for the slow mo, colored smoke would show airflow with little editing and explanation needed
most colored smoke i know is toxic xD
@@rafcion6726 even the stuff they use for photography?
The production value on your videos seems to have just jumped up considerably, this was really pleasing to just sit and watch (not that they weren’t already) and very interesting as always congrats
I love that I can hear the different engine sounds and compare them to ones I've heard around me out and about, the 135 degree v8 sounded more like a muscle car and the 45 degree v8 more like a truck engine to me. Thanks for making these!
Man what a huge amount of engines you designed for this video! This is exactly why I’m subscribed. Keep it up man, stay safe.
now that you've got an ender 5, you should try to print some shorter crankshaft pieces to get a stroke length shorter than 3 bricks. I would love to see what kind of speed you can get with a shorter stroke length. Those pistons seem to have some decent power; I could imagine maybe a stroke length as low as one brick could work.
Please tell us how you've mastered mechanics and engineering. mention the books or any other source that have had great impact on your journey.
up
probably school lol
Have you considered dry ice and water as an alternative power source?
Put it in a metal container to hold the pressure
Cool idea
I was thinking baking soda and vinegar
I like the idea of the pressure source beeing a phase change reaction, you'd need an expandable bladder of sme kind to keep the pressure constant
How about fumes from some flammable liquid?
@@zadovrus1624like oil
Its crazy how they all sound very simular to the real engines. And i listened to a lot of them
Your cat assistants are so cute!
This is really ingenious, I would have never thought this was possible with Lego!
2:00 thats a hard one... uhhhh hmmm hhhhh aaaa is it 1?
nah, I thinks its 1
8:34 sounded like steam train
Steam trains use hellishly long pistons
5:20 notice how it needed a bigger flywheel to start
That's how you know power was lost
3:23 Cat.
Cat.

Brick technology starts getting sponsors and not one negative comment about it. I love it, you keep the lego community satisfied with brilliant content and deserve the payroll. Congrats!
Id love to see you power a LEGO clock with an airtank❤could run for weeks
Hi!
I'm vrey happy to see these experiments with the air engines! Especially the firing order one!
Question:
Do you plan on using flat-plane crankshafts for your four/eight cylinder engines? You're using cross-plane ones now (90 degrees between each pin, while flat would be 180, basically the two outer pins being on one side, the two inner ones on the other). Flat-plane cranks are used in most 4 and 8 cylinder engines, the exceptions being some sports bikes, which still use cross-plane.
The best thing in this video is when you show applications for these engines, such as powering the pump! Awesome stuff as always
As someone with a love for lego, and a slightly more than casual interest in engines, I really enjoy these videos😊
u must invent that piece you've printed 7:48
I found it really interesting where you changed the valve timing, the firing order etc, i think making a full lego car with a pneumatic engine in and tuning it would be really cool. You could even make a dyno to test rpm
This incidentally really helped me to understand how engines conceptually work, thank you !
If your next video is a full-size working lego car, I wouldn't even be the least bit surprised. Incredible work!
Never opened a notification this fast
lol
Also this video is freaking amazing at describing how a engine actually works like for an example I didn’t know that’s why a flywheel exists
For me, the most impressive thing in the video was the adjustable angle motor! Great idea!
3:08 kinda unintentionally sounds like an engine running without a header or a manifold
1:54 sounds like a VW TDI engine😂
This is extremely well put together. It explains things very clearly and simply enough that a lot of people would understand. I love practical models like this. Amazing job!
Edit: Also has cats. A+
Thank you for sharing your process.
Question: could you do an experiment in a video to demonstrate the power of these engines compared to traditional Lego electric motors? I understand if the point of this is purely educational but since they're both available as LEGO building/engineering techniques it would be nice to see how these arduously-produced stack up to premade motors (drive sources) in terms of ... torque, I guess?
1:08 sick beat lmao
Something I’ve always wondered, does the orientation of the pistons matter? Like, does an in-line 6 vs a v6, vs a flat 6 make a difference beyond how compact it is overall, or is there a significant differences impact on torque, reliability, etc? Might make for an interesting video comparing them?
It indeed does. Inline 6 engines are notoriously more reliable and smoother because of less vibration and wear, flat sixes rev higher for whatever reason and v6s are cheap
I seem to remember 1-5-3-6-2-4 was the firing order of my dad's 1969 Falcon.
it was engraved in the engine block.
yes if you use a valve gear like stephensons or walschearts if i had more hoses i would 3:46
nah i4 be 1-2-3-4 and make it a crossplane
wow I love it. You should really develop a noise music piece out of these. Please write me if you are interested in performing those things live or if you are willing to share the plans for those machines so we can listen to them on a big soundsystem. I am Leipzig based so hopefully not too far away
Yes another video I’ve been waiting for this one I love your videos and there so high quality
I love how all of the "messing around with lego" type channels have cats who come and investigate the builds. definitely a crossover in demographics going on here.
Huge fan of these pneumatic engine videos
I used to build mini garbage compactors out of Lego using those yellow air cylinders. The compactor worked well.
Awesome inclusion of the turntable. Loved the camera angles and editing.
9:20 I find this but funny because you are using air pressure to make rotational energy to then turn back into air pressure to power the car!
This is so relaxing & kind of serene the engine sounds & acceleration are good & A1 :D
Those pneumatic engines are so cool!!!
Can you build a V8 muscle car with clutch and gearbox? Kind of like the truck you’ve made but bigger and faster ;)
And maybe you can create a pneumatic exhaust system like on the Dodge Challenger Daytona SRT e-muscle concept to give it a badass sound 😏
I love how the cats come by and get all curious. 😸
Nice experiments! I noticed that you zip-tied some of the hoses to the t-pieces to prevent them flying off. If this is the case, I would recommend using stepped/grooved t-pieces, since they grab onto the tubes much better and resist popping off at high pressures. Good stuff though!
3D printed lego parts is awesome! I can't even imagine how powerful he will be now
Awesome video! It would be interesting to see a comparison of torque output between 1 and 2 stroke engines, as well as switched vs non-switched valvetrains.
Next try to make an engine out of linear actuators
The effort you put into this is astronomical
7:15 i have a volvo 850 from 95 with an inline 5, and its nice to see those oddball engines configurations get some love
Not gunna lie, at 0:10 I thought it was vibrating rather then it being on a turn table. Keep it up!
Your editing takes this to an entire different level. Well done man. Love it!
Incredible work as always
It's so cool!, it sounds like an actual engine
If this guy was making cars, we’d never have an energy crisis
3:40 sounds lika a diesel to me)
Very, very cool presentation. Clear, understandable and engaging. Thank you.
car nerd here, love that you made a handful of real engine layouts!
i cant tell u how i love ur videos so much man amazing and interesting content
That I4s valve design is the most satisfying thing in the entire video
What a simple yet brilliant way to level-up the production value with lazy susan! Fun and interesting video once again, keep it up!
I'm all bricked up for this air engine videos!
I cant help but think some of these engines would be really cool in large rc boats
6:57 1.9 TDI
That electronic valve control is an interesting concept, it’s almost a hybrid engine
The in-line 6 sounds like a real i6 too! That’s amazing. It immediately reminded me of my old jeep Cherokee and a diesel engine
Air engines + lego = 👌⚙️
We need more air-engine content on this channel!
You should make a propellor engine for a lego plane with these. Edit: make the plane move with the engine.
I wanna see someone make a steam ship with this type of engine.
Awesome! Only need some vacuum engines on the channel now!
YES 3D printing has come into the mix!!!
13:10-13:19 the cat's movement synchronized with the engine noise made me think of some vehicles (particularly old cars) that do that sometimes.
i got an idea for your channel! make an engine with a gas pedal with pneumatics - actually do you have an engine that has a variable-controlled RPM or do all the engines have speed controlled by the psi? in any case, have a gas pedal and a clutch pedal that goes to a transmission like at 4:45... it would showcase how one is supposed to drive a manual car by showing the theory of operation in lego form.
I would love to see different vehicles tested with different varieties of engines. Though probably the only thing that can hold the engine is a large LEGO boat.
These aren't *just* engines. They're *masterpieces.* Every single *hiss* of these engines is like a *heartbeat.*
Immediate proof of why steam or air powered engines will always have more character and life than an ol' diesel or gasoline engine.
Can I be honest though
I can feel that with all three categories
Air/Steam
Gas/Diesel
Electric
They all have different dialects, but you can feel the joy of doing their job in their own unique way
I would like to know more about the reversable air engine. I cant quite get how it works
IVE BEEN WAITING FOR THIS
Flat\Boxer was most ballanced....Great job!
These videos are like a holiday every time
Wtf Bro eres un genio, el mejor contenido de lego y mecánica que existe
Underrated youtuber, he’s amazing
I'm looking forward to seeing your VR5 (some VWs), flat-6 boxer where left and right cylinders are 180 degrees apart on the crank instead of sharing a pin (Porsche), V10 (Viper), V12 (Ferrari et al) and of course W16 (Bugatti)
I didn't know there is a firing order for an engine. I always thought of the incorrect one, i learned something amazing from brick technology again.
Your videos are the best, I really enjoy the effort you put into every creation and video edition. You deserve everything good thing in your life. Keep doing these videos
Thanks a lot, this means a lot to me.
1K?!?!!!!!???
0:40 what happend to 6.1 😂
Ran out of buget?
The demonstration of the V8 was really cool, fancy how the angle of the cylinders relative to each other can make such a huge difference. The way you showed proper firing order of cylinders was also really neat and easy to understand.
I do still wonder about 1-stroke vs 2-stroke engines: it seems 1-stroke is more reliable, so why is 2-stroke even a thing? Easier/cheaper to build?
Actual one-stroke engines do not exist because they cannot complete the combustion cycle in just one stroke, you need at least two strokes. As for why we have four-stroke engines, because of emissions basically. The biggest engines in the world (those on cargo ships) are two-stroke, because two-stroke are more efficient in terms of raw power over four-stroke. Also racing bikes (those that do not have to comply with emissions standards) are two-stroke for the same reason.
What about building a gasoline engine like a steam engine? Combustion chambers on both sides of the piston head, would it work?
@@HB45175What OP and Brick Technology meant was "single-acting" vs "double-acting" engines
The i3 sounds identical to a Deutz F3L912! Great job!
Geeze, every episode is more impressive than the last
I had a crazy idea but if done right it could be the best idea. What if instead of a lego pneumatic engine powered by air, it's powered by water. There is a water pump pumping to the piston and when the piston retracts the water goes out. (Sort of like real life combustion engines but with water and would unintentionally cool the engine) (Most likely use a switchless mechanism) also test to see if it gives it more performance like torque and rpm. (Also try with big pistons if you have enough water flow) (This idea is dumb because it could damage it but could look cool and make the engine better)
my favorite channel because I love legos and engineering
Love it.
Next project: pneumatic clock?
I really like your channel, the presentation is awesome.
