@@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.

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

[@IstasPumaNevada]

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.

[@scarrax0159]

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...

With the realization of ones own potential and self-confidence in ones ability, one can build a better world.

[@jdbrickcreation]

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

[@DarthRelkew]

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

[@alexweiman4749]

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.

[@LizzyTheProto]

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!

[@LOUDMOUTHTYRONE]

No way... Math and science is racist to Rihanna's kids.

[@drunkenhobo8020]

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.

[@trashheap5590]

When you grabbed the pinion at 10:05 to show the torque it sounded almost identical to a cammed v8 idle. Perfect chop.

[@hibernator8198]

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.

[@kyledragonheart3875]

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

[@henke37]

@@kyledragonheart3875 This way they could even make specialized switch parts that are more optimized for the task than the existing one.

[@burgeal]

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.

[@Dysiode]

It's amazing how much of the engine sound comes from the parts rubbing and not the combustion!

[@JustSushi0]

When they’re idling, they really do have some sort of hypnotic quality. You’ve tapped into something familiar yet fresh. The way they sound and look, just the overall aesthetic is really pleasing and impressive. So when are you throwing these in a car and running some tests?

[@skinwalker69420]

Have you, perhaps, found your fetish?

[@Admiral45-10]

11:45 If you're wondering why this happens, it's because of engine-alternator commutation rule. Electric engine and alternator use the same technology and physical principles to work, doing the exact same thing but in reverse: - electric engine converts electric energy into mechanical energy - alternator converts mechanical energy into electric energy ...so when you apply current to alternator it will work as an engine, and - as in this case - if you apply torque to an engine, it's going to produce electricity. They will be a little less effective than the other one in this new role, but it will absolutely work.

[@naturesoundsaustralia]

Its just amazing how these sound like a real motor…. Really makes you appreciate the design of engines in every day cars.

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!

[@CommissionerSleer]

Really impressive work. 1 suggestion: I couldn't see a counter-balance on the radial and it seemed to wobble a lot as a result. I think it really needs one to let it run smoothly. With careful balancing it might be able to get up to some serious rpm and power.

[@zchen27]

Radials also work much better with an odd number of cylinders so it can consistently maintain a 1 cylinder gap between power strokes. Although I'm not sure where you can find odd subdivisions of circles for Legos.

7:45 on a real I4 engine, you would always have the ignition offset. So cylinder timings 2 and 3 switched. This is for possible oscillations, which would be eliminated.
