Note: In real life the U12 and X24 have 3-throw crankshafts (pistons are 120 degrees apart) and the 42-cyl has a 6-throw crankshaft. Those are a bit complex to do with Lego so I used simpler 2-throw cranks (180 degrees). Thus firing orders are not correct in those engines. Also the 42-cyl Zvezda M503 was done with radial-6s instead of the real life radial-7s because I couldn't find proper Lego parts for connecting pistons to the crankshaft. The Sherman 6046 U12 engine gearing and phase offset between the shafts were unknown to me so I just guessed them to be 1:1 and 90 degrees. In other ways the models should be correct (hopefully). The V8 has a flat-plane crank that were used in Formula One engines. Lotus 46 H16 flat-plane crank, gearing and phase between the shafts should be correct according to the schema image I found (shown in the video). The U12 has both crankshafts rotating to the same direction as was explained in mapleleafup forum.

@@spccadett I don't think high-cylinder-count engines are typically ran at higher RPMs anyways. There's so much torque going to the shaft already, it's more materials science than design engineering by that point.

this actually makes me wonder if most of the sound an engine makes from the front is coming from the parts moving, not the actual explosions happening

[@cmdrTremyss]

mind ~~blown~~ moved

[@daveolifent4477]

The biggest contributor to the sound would be the frequency with which it is happening. For example, a V6 engine running at 4,000rpm would have 24,000 explosions per minute, or 400 per second. So an output frequency (sound) of approximately 400Hz would be attributed to the internal combustion. Other frequencies that are mixed in with this frequency would be attributed to other variables, such as cylinder salience, engine vibration based on the torque moments, and imperfections in the engine balance, timing belt path etc. This video gives a good basic idea about different engine configurations, but is not accurate in terms of the cylinder timing (ie: angle offset and ignition timing of cylinders) as well as other variables such as crank angle, as well as the fact that engines use the cylinders to drive the camshaft, where as here he is using the camshaft to drive the cylinders.

So Lotus either used 2.0 liter Climax engines (enlarged 1,5 liter regulation V's), BRM 2,0 liter V8's and sometimes the BRM H-16, which BRM had designed for the own P83 F1 car first.

I just adore how these tiny plastic pieces start to sounds just like a real engine when up to speed.

[@NigelMarston]

Agreed, although the V8 was a flat-plane crank version, it had echoes of Ferrari V8s in it. Makes me want to try an S100 in the front of my car. :D

[@TransGirlGaming]

@@NigelMarston yeah it did lol, I always love hearing Ferraris flat plane V8s spool up

[@NigelMarston]

@@TransGirlGaming If you like those, I highly recommend you listen to a 4.5 litre TVR Cerbera. That has a flat plane crank with an unusually-narrow V-angle. It makes it sound very angry. Despite sharing many similarities with the modern Ferrari V8s, that narrow angle really twists the sound. I had one - still think it was the best sounding engine noise I ever heard. Not comfortably "woofly" like a cross-plane V8 but purposeful... something you imagine the Devil would drive.

[@TransGirlGaming]

@@NigelMarston oh I've heard the TVR cerbera a lot lol, my neighbor had one for years till he sold it at the start of Covid it was this beautiful Rose gold colour, but honestly any engine sounds amazing to me even the old factory I6 in my 81 C10 lol just something about a running engine keeps my mind at ease

that radial engine is amazing... i gotta start building stuff with that kind of equipment, holy crap.

[@moominpapa1980]

I must say the motion on that radial was somewhat hypnotic

[@Hybris51129]

This does a pretty solid job of showing how smooth some of these configurations can be and why some motors are better suited for higher rpms than others.

[@pinotgrizio3567]

Right but it seems backwards. Usually A 12 piston engine would be much smoother than something smaller.

[@Hybris51129]

@@pinotgrizio3567 I think that's more because the Legos aren't as solid or as stiff as a traditional engine block so any vibration is multiplied instead of just absorbed. Fewer cylinders + less gaps between Lego blocks = less vibration. At least that is my guess.

[@hiddensky1164]

@@Hybris51129 They need to be lubricated too. The reversed transfer of torque may also be a factor, instead of the engine spinning the shaft, the shaft is spinning the engine.

I wanna say, the U shaped tank engine sounded closely to a tank, too. Not at 3k RPM, as I'm pretty sure, most tanks never revved that high. But around baseline, lets say, 500 rpm, it had a similar vibe to the real deal.

realistically, a s100 would be nearly physically impossible to put in a car. A real version of that would probably be close to the length of a full size SUV, or school bus. Even if you make the engine 10 s10 engines side by side, it would still be impossible as there would likely not be enough room in the engine bay of a car. Still though, we can only hope

You'd be surprised to know that hypercars have more cylinders than Semi trucks. Most Semis have straight-six engines, though this comes down to Straight-Six engines being the longest lived and most durable cylinder layout.
