Sounds like it would take some rebalancing, and it might do funny things
to the mixture if you use an open plenum intake. The more I consider this
the more I have to wonder why in the world anyone would want to do such a
thing?
I was inspired by the 3 cylinder Bruch Porsche to actually considered
building a single rotor rotary engine. No cylinders to sleeve, but it would
drop my engine class from E/ to G/. Whatever I do I still have to deal with
having my engine displacement tripled since the Wankel is a
non-reciprocating engine. Then there are all the smaller piston engines
that have more potential than 1/2 a rotary, so this idea will most likely
stay on the drawing board.
Major changes in engine class would be the only reason I can see for such
an engine, but then why not change all eight cylinders to maintain the
engines breathing efficiency? I don't think it's the most practical idea,
but it's an interesting one. I'm curious to see what others have to add.
