If someone is interested in the Bishop rotary valve, I would recommend looking for Glen Horrocks' dissertation "A Numerical Study of a Rotary Valve Internal Combustion Engine",...

Any news here? :)

I am still working on my small rotary valve project... ;)

Nice that this thread is "back from the dead" :)
@D.L: Maybe he uses an oscillating design - but I think that you could achieve this behavior with cleverly designed openings of the rotary valves.

This is one reason for overlap. Which, of course, you don't need with many of the rotary valve designs.

Other reasons are, as Dzuari mentioned above, "dynamic supercharging" of the engine (exhaust...

Hm...
I still have a little bit of a problem with "more open time / area" + "less overlap" = better / more efficient... Please don't take this as a criticism!
I fully understand that you don't...

Thank you for the answer!
I'm curious to see your solution :)

First post in this forum, so hello to all :)
