The video show a Briggs and Stratton running on gasoline alcohol and
acetylene, I wish it were possible to do this with the rotary to test
some ideas

Can you share those ideas Alex? :-)

I was thinking along the ideas and modifications you Frank and others
were talking about a few weeks ago, guiding flame fronts, additional
spark pugs (side by side) more complete combustion of hydrocarbons
instead of mixture igniting while going out the exhaust, changing
compression ratios with inserts, additional shapes to induce more
swirl for complete combustion.

If you could film it in real time what a great way to test these
ideas if it were possible to have a clear view on to the rotary
combustion chamber.

Attempts have been made to do that in the recent  past (2015) on the
rotary but due to the geometry and other temperature considerations
it has not been very successful.

What has worked recently has been CFD. CFD gives you velocity and
pressure. CFD is improving all the time. If somebody built my idea
of a multiple piece  rotor that bypassed squish air it would be very
very difficult to see that optically. It was CFD results that gave
me the idea.

Ford obtained some patents for a Wankel with plugs in the side plates, you can
easily locate it all in Espacenet, download is open and free of cost.
