I had no idea this type of valve was a thing. Interesting to learn a little about. Maybe something like this would make electrically controlled variable timing more viable and thus improve the efficiency of ICEs?

Rotary valves are more present in the musical instrument world, where they are used on French horns, some trombones, and some tubas.

On the topic of unconventional valves in automotive engines, I'd recommend taking a look at Koenigsegg's Freevalve technology.
