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?

    Had an RX8 for a tad. Rotary was fun, but reliability wasn’t there. Apex seals are a routine thing. Miss that car, but don’t miss the repairs.

    These rotary valves are totally different, but I can imagine the additional distance and air pathway from the valve to combustion chamber would significantly decrease compression ratio. Turbo/supercharged would probably be mandatory to compensate. Perhaps this tech would probably find it’s way on large displacement industrial engines first.

      Yep, this valve would have similar challenges to a rotary engine, since they’re effectively one big rotary valving system.
