I see that another displacement round was held while I was unfairly being
held captive in the hospital - so I will make a short rejoinder.
Displacement is not always related to output shaft rotation - ie all
the cam engines out there. I am sure you have no trouble computing
their true displacement.
Both German and Japanese developers were heavily motivated by tax laws to
exploit the potential confusion.
Each rotor is carrying three "charges" each representing about 600cc of
swept volume each in various parts of the four stroke cycle - just like any other 3
"cylinder". four stroke engine.
German and Japanese developers saved millions in tax dollars by claiming the
smaller
displacement - I wonder what the numbers would have been if the Wankel had
been developed by US manufacturers where displacement is a good thing?

That is not the reason. The displacement is what it is.
From near the end of the last discussion on this subject and from
now on I will let R.F.Ansdale do all the talking for me on this
subject. You will have to tear him apart piece by piece to prove
it to me. Furthermore Ansdale's excellent detailed and rigorous analysis
was sufficient to silence all of your former disciples :)

I wasn't going to say anything, but your last sentence requires some
comment. Ansdale hasn't silenced me, it's just that we are talking
about two different things. If I've tried to make any point at all,
it's that displacement is a measurement of
_volume_, not work or power
or anything else. As soon as you start talking about how to compare
the rotary to something else, you are talking about something different
than displacement.

16B is not 4.8 L it is 3.2 L.
In engine engineering displacement is precisely defined as the
volume of air processed and not the totally physical volume of all
the chambers. Andale addressed this confusion when he discussed
two cycle engines on page 55 and 56. The rotary is not a two cycle
engine.
