See? this comment is an improvement over your previous ludicrous comment of "No, you don't really have the right to disagree". Keep working on it. Meanwhile, read this. https://news.mit.edu/2014/liquidpiston-small-efficient-rotar... Especially, this part. "The X Mini is essentially an upgrade in design and efficiency of the compact Wankel rotary engine, invented in the 1950s and used today in sports cars, boats, and some aircraft."

Yes, I see how the article literally says this is not a Wankel, but rather an "inverse Wankel". Taking many of the main ideas behind another engine and using those ideas to make your own (with different key features) does not make it the same engine.

My saying you don't have the "right to disagree" was a response to your ludicrous assertion that an engine can be whatever you want it to be, not what it is. Any ludicrousness coming from that is purely a function of how ridiculous your original response was.
