Kinda cool Wankel Rotary video
Yeah, yeah, we know, they suck...apex seals, blah blah. And yeah, missing a finger.

I agree though, I love these slow mo clear cover videos. Really hits home how the various types of engines work for me.

Very neat! Amazing how good those apex seals are (for now), considering the motion of the part and the contour they have to follow.

Its all about power to weight/size in a sports application, so in that they are the best. And in every other way they are the worst. Poor reliability/longevity, poor fuel mileage, use a lot of oil etc etc.

Very cool video!
Rotaries are neat/cool and all. But hideously impractical. Fundamental issues with massive inefficiency due to broad rotor faces rejecting heat and problems creating reliable sealing. F20C reconfigured as a V4 would be nearly as compact as the 1.3L rotary and about the same weight, while giving a bit more power and 1.5x the fuel mileage. The novelty of the rotary is just not worth it...
It sucks that Mazda's "Vision" concept car is saddled with the rotary. That car would be *brilliant* at 2750 lb. with a ~275hp 2.5 liter NA V4, which would be totally doable...

They may not make great car engines, but I see the military is looking at rotaries for remote power generation and other things where a really light and compact engine is beneficial. The one in the video is for a RC airplane. I wonder if small rotaries might make a good engine for small power equipment like weed wackers and chainsaws. And I wonder where that guy's digit went.
