I love when it starts goings so fast that it outpaces the camera frame rate and appears to reverse direction for a moment
Even better when it happens twice on the same engine!
And then it starts looking like it's fading
It's called aliasing, and it's a really cool effect.
This has nothing to do with frame rate. What you mean is the shutter speed :)
@@BanterEdits Shutter speed has absolutely nothing to do with it, he is correct, it is framerate.
I really like how most of these actually sound like real versions only quieter
Exactly! The rotary engine actually sounds like an aircraft.

Ah yes, the humble 4-banger, inline four or I4. The heart of many, many modern automobiles. Economic commuter car, or screaming highway beast, these things are everywhere now.
The 900cc Kawasaki Eliminators from the '80s had straight 4's as well.
Almost 90% of all cars have this humble, reliable little engine.
I love seeing how even though they’re mini engines, the balancing and vibrations are still super accurate to the real thing, for instance the parallel twin vs v twins are a great showcase on why you’d prefer one over the other
The vibration difference between the 180° and the 360° S2 was astonishing
Makes sense though right? On 180° the forces are offsetting eachother while the pistons are "firing," while on the 360° both pistons are exerting force at the same time in the same direction
@@gobblu would the 360 degree vibrate expodentially more because theres nothing stopping it?
@@benevery no they would hit a max vibration travel and start moving of there own against the friction of the table, if youve ever seen a construction packer it moves off vibration
No Straight-6 though - that would result in no vibrations at all
@@gobblu An inline twin with phasing like that is uncommon. In a 2 stroke the pistons would be 180 degrees apart. and so would 'fire' evenly as every time a piston reaches the top, there's an ignition.
When motorbikes started moving to 4 stroke that kind of twin setup ends up not working well, as each cylinder only fires every second top, so you'll always have uneven spacing of the ignition. which also complicates the ignition system as well as making the engine feel 'lumpy'
The solution is to set the pistons 360 degrees, which means each piston still fires on every second top, but the ignitions are staggered so you still get one ignition per revolution. Vibration is taken care of by a larger countereight than on most engines.
Such a system has the same basic ignition a single cylinder uses, it simply fires both plugs at the same time but because one will be at the top of the exhaust stroke it does nothing, hence the term "wasted spark ignition". Wasted spark is used on all sorts of engines, even modern ones where pairs of pistons both reaching TDC together, but on different phases, spark together, which can greatly simplify the ignition system.
In twin cylinder 4 strokes there is a more illusive "big bang" set up which if you mess with the cam shaft you can put both pistons in a pair into the same phase and they fire together acting like a big single. People do this mainly to make the bike feel punchier, though there's no extra performance to be gained as double the power is offset by double the time between firing.
The Radial Six one had so many issues in filming it because it was trying to take off and fly around the room.
the radial engine, knows where he belongs, the sky
@@IamJmc1992 the only thing that grounds them is a tank, like the M-18 Hell Cat
So is the M4 series for a while
Jokes aside though, those things are pretty much just attached straight to the propeller with nothing really in-between (with a little exception during WW2 involving a certain model of Sherman tank), so not to surprised that it shook the test rig to pieces, when the angled tail shaft got involved. It was very cool to watch
@@moohooman I mean, it's not really a "certain model" of Sherman. The majority of them used radial engines. The weird Shermans are the ones that *didn't* use radials. Like the one that was used some of the British Fireflys, 5 car engines strapped to one flywheel.

radial-6: *sweating intensifies*
that's why engine balancing is big deal just look at flat boxer 2 and straight 2 180° they don't need additional weight for balance
@@3rdDanPrime The best balanced engine layout is straight 6, they dont need balancing shafts at all
Part 2 : piston order and crankshaft tweaking. Flatplane vs crossplane V8 for example
I bet the U2 & H4 engines would be smoother if the 2 cranks were 180° apart
I would have thought that he would just naturally offset them by that but ig not
@@hurlaky43 you would have less vibration, but the force would be turned into torque instead of linear force, which if it were a real engine may be less desirable

I've made a cross plane V8, but I had to cut a piece shorter to make it.
A flat plane V8 us just two of the inline 4s sharing a crankshaft, so has all of their properties.
The cross plane is smoother, as it doesn't have the secondary imbalance than a flat plane has.
I'd love a straight 6.
V8s irl are super cool...
Straight 6 doesnt need counterwrights, but its impossible to make with lego becouse you can only put the lego pieces in 4 different direction, i6 needs dividability by 3

The radial engine actually sounds like a propeller plane
now we need an R18
Maybe because this is propeller engine? Hm...
Some WWII propeller planes (mainly naval aircraft) used radial engines. Those meant for land warfare mostly used inline engines.
Radial engines in aircraft I’m familiar with used an odd number of cylinders, that might be an interesting comparison. Are there “modern” radials with Ann even number of cylinders?
@@h8ter1927 Given propeller planes are hardly used nowadays because jet engines have taken their place, probably not. The advantages of a radial design in WWII planes are that the structure allows for more airflow over the pistons, aiding in cooling. Also, because more cylinders are used, there is greater redundancy in case of damage from enemy fire. These points are largely moot nowadays, so I think this is unlikely.
reminds me of the single piston car i built out of technic lego back in the early 90's as a kid. Had a drivetrain, steering rack! Lego Technic has come a long way since then. Great content! Keep it up :)
This actually helped me learn a thing or two about engines.
Nice
This is a perfect way to see how actually balanced each engine is.
I was waiting for the straight-6 and its exquisite balance.

Incredible video! I never understood the basics of how engines work and now i do👍🏽💯😁
I love how this video demonstrates the importance of counteracting forces.
Do a wankel rotary next! (If it's even possible with legos)
I love that this is a perfect demonstration of in phase and completely out of phase waves and how engineering is just infected with it. Everything that deals with movement at some point pretty much deals with wave forms and that’s apparent in looking at the I-4 and boxers stability vs the radial engine which is hardly able to be contained.
For the radial engine, he put a relatively large mass on the throw of the crankshaft and then only supported the crankshaft on one side. There was only going to be one ending to that.
You can actually use Legos to test the balance and durability of an engine design... what the fuck
@@pneumaticslap3344 To a certain degree? of course you can. Anything with weight will be able to have its fundamental physics checked as long as the movement is the same as the full-scale machine and all parts weigh the same in relation to each other..yes of course it's a good design.
Yes, although I4 has great primary balance but a pretty bad secondary balance. Also he should have held the assembly in place from both ends not just one on the radial.
This is the best explanation of how engines work there is on the internet and the dude doesnt even talk. Respect.
This isn't really an explanation of how engines work. However, it _is_ an explanation of why certain cylinder configurations are more stable than others.
Those are jus the shapes
no
Building one of these engines for the batmobile was so satisfying. Watching the pistons move as the wheels turn is so fire.
Extremely engaging. Thank you.
Everyone talking about how stable the Inline 4 is, and I'm out here staring at the S2 180 barely even moving.
It's okay baby, I see you.
@Vrylle Llagas Yes it look lot more stable when both cylinders have different momentum.
The I2 design won't be ideal in a typical Otto 4 stroke design. Because the power stroke is not displayed here the balance is good but in reality the near 180deg of no power rotation makes the design questionable.
E.g. Fiat tried to make a 1.0L TwinAir 2cyl turbo for the 500 city car back in 2011. It was a novel concept but alas it idled rough and was far less refined than the 1.2L 3cyl and the MPG gain over the TwinAir was negligible. Needless to say the Twin Air was discontinued from the Fiat lineup by 2017.
Just imagine how stable the straight-6 would be.
The H4 should have been the same, had the lower pistons moved oppositely to the upper ones, as they did in the real engine - and as they did in the various "square four" engines, which were similar. A square four is probably more accurately described as a U4 engine, though.
The 180° twin is very common in motorcycles because of the balance improvement and where the uneven firing isn't a problem, it simply adds character. 270° sounds sweeter, though - like the 90 degree v twin.

@@Trades46 and more efficient than use more than 6 cylinders, the known Castrol Supra had a inline 4, also rally cars usually have turbocharged I4 engines

This whole channel is just the answer to the question "what can you do with an unlimited Lego budget and a mechanical engineering degree"
You you taught me about engines in such a good way, that i didnt know i was learning
cute that the pastic lego mock zylinder housings have cooling fins
It’s cool seeing how some configurations are so much more balanced.
Yeah them being more stable is some of the big reasons certain engine designs are used more
Here are the S2 180°, the boxer and the 4 banger, most of configurations aside of that are imbalanced because mass displacement is not compensated.
In real life they're always balanced by adding counterweights, if necessary
I like how stable the S4: Straight-Four Engine looks in motion compared to all others (why isn't it in the compilation at the end?).
It looks like the pistons should be in opposition of phase when going in the same direction and in phase when in the opposite direction for the "engine" to be stable. I think the one you mention is extra stable because of the symmetry that the similar two piston one doesn't have for instance
Actually the boxer engine is even more stable because the pistons go in the opposite direction basically mirroring each other. The 2 cylinder model shown generates almost no vibration and manages to do so with 2 cylinders less than the straight 4.
@@Robozgraggi yes but it's also less powerful, and as well the "consistentency" of the power begin generated should be taken into account, As I believe the less consistent the power the easier to stall.
Ofc I am not an engineer or mechanic and thus discovering the "Efficiency" and value of these engines is just speculation on my part.
I just wish he went up to an inline 6, as that is the most "naturally balanced" engine configuration possible.
Similarly a v12 (basically 2 inline 6 engines) which is why both configurations are both loved so very much
@@Nessinby I have no idea what you mean by "consistency" and "less powerful". In terms of overall performance the boxer engine is better. But it's more complex and expensive than an the inline engine.
It's so satisfying to watch this and you can learn from this video
These are all awesome, but I think my favorite to watch is actually the Opposed-Piston engine
This just shows how so many configs are screaming and trying to desperately tear themselves apart.
Meanwhile, inlines just tbe chilling.
Hope to see a followup video with even more engine configurations
and even higher RPM
It's so cool to see which configuration have most and least vibrations. Also most of them had a RPM sweet spot where the forces almost cancelled eachother out and they ran smoothly. A V8 with 90 degree vs 180 degree crankshaft comparison would also be awesome.

This was great! Two suggestions/requests:
-I was hoping to see a straight-6 engine, since it's naturally smoother than other configs (unfortunately, one of these benefits comes from a 120-degree crankshaft offset, which can't be as easily done in lego; perhaps that could be a challenge to set yourself against? Maybe using part 4265a and some short shafts held together with longitudinal restraints?)
-Those shaft joints you were using transmit power unevenly if the input and output shafts aren't parallel, I think; this might be a neat demonstration to do.
I love it when the engines start to spin at a speed that is a multiple of the camera speed.
