It's not just another wankel engine tho, it's significant modification to the idea and comes with few interesting improvements (and some other drawbacks). Basically, the intake and exhaust is delivered thru the rotor, not ports on the sides, and the seals (the achilles heel of the wankel engines are on the outside of it which in theory would make it possible to both replace them without taking apart whole engine, and oil them directly, without putting oil into fuel. The bad part of it is that it would probably be pretty hard to make multi-rotor one
