From what little I've read [1], it does not look anything like a Wankel engine. While they both confer similar engineering benefits (though not claimed fuel benefits) compared to a reciprocating engine, the Wave Disk Generator/Engine, 1. uses compression of air/fuel mixture for ignition (like a diesel engine), not a separate ignition system 2. has an exhaust system that is both radial and circumferential using centrifugal/centripetal forces to clear the gases. Essentially exhausting all the time. 3. has an intake central and orthogonal to the plane of the rotor. Essentially continuous intake. 4. has no "hot spot" fixed housing locations for different parts of the thermodynamic cycle like in a Wankel engine, so, there is no need for a separate cooling or heat distribution system.
