whaddya think about these studies?
on top of Papa's comments concerning charge lag issues in the carb:
I would imagine that to compensate for charge lag in the block, you would want to maintain cross section area and mass flow in balance with pressure gradient. so i think the coolest problem that you could run into is intake tract resistance.
let's say instead of conventional style reed block, you could use duckbill valves. you have an intake manifold that leads from 1 - infinite valves. (e.g. one big gulp straw, or 4 regular straws, or 20 coffee stirrers. and on). so each one of these has a duck bill valve on the end of it. a series of tubes (-_-) is real nice to think about from a fluid dynamics perspective, compared to the transition to a big square thing.
you can start to imagine the pros and cons of more tracts vs less, how much to increase the cross sectional area, how far the valves have to open, tract surface area resistance. and on and on.
I think you'll always have the lag issue of when your charge is expanding sideways, it is not moving forward.
unless you have regulated forced air induction, and could tune your intake charge to overcome these tendencies, but I don't really understand how forced intake works on a reed valve.
that being said, rotary vs reed depends a little on the application. from a singular peak HP perspective, i believe rotary is superior, but reeds are a great "problem solver" of low rpm blow back and power harvesting. making them generally more usable. i bet they are also easier and cheaper to manufacture.
as far the "if it worked they would've already done it..." i disagree. Most of what we have is fueled by market, application, cost, politics, cultural training, and necessity. remember how young the combustion engine really is! i think we see a lot more of "if it isn't broken, don't fix it"
diminishing returns...what gains are there? is it worth it?
interesting exercise though!
