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?

That's a great point! And maybe part of the reason they're not widely used. Not long after these came around forced induction took off in motorsport and now it seems everything is a small engine with a turbo or two.

I wonder if optimized electronic timing could rival a small engine with a turbo for commuter cars?
