I try not to link youtubers, but I'll make an exception for F9's Wankel video.

https://youtu.be/-3HBAvkc4a0?si=9NJd4B-VK1LxfXWy

Although he's basically a motorcycle blogger, the production values manage to pump a lot of great physics[1] / MechEng information into the entertainment. There's not many mediocre videos on his channel, but this is one of the better ones.

The gist of this video: the Wankel does have some[0] fundamental problems as a concept. There's workarounds (none of which I could find in the OP, although using a Wankel as an ePMU is probably ideal) but also a point of diminishing returns apart from specialized platforms like UAS.

Rotational, high-flow, high-rpm . . turns out you're already halfway to a gas turbine anyway.

[0] Rather a lot

[1] The host is a physics major, IIRC, rather than mecheng, which was interesting.

It felt like that video was targeted more at teenagers and/or immature dudes (which is totally fine, it just didn't resonate with me).

I really liked these two:

Yeah, I'll buy that. I use F9 to sneak some moto knowledge into my nephews, who have . . I don't even know what they call attention spans these days. . negative attention? Unless it's some incomprehensible card game. Anyway, good vids!

Both links go to “How rotary engine works”

Targeted at nerds who ride motorcycles perhaps? Other than the Revzilla guys, what motorcycle tech/errata video channels do you recommend for the discerning and mature?
