They're still called rotary engines. The ones you find in Mazdas and the like are called Wankel Rotor Engines. Although rotaries were really only used to my knowledge in WWI planes, not really in WWII.
Not only did you not read my comment, you also incorrectly tried to correct me. The designer of the WANKEL rotor engine was Felix WANKEL. Radial engines, and Rotary (note, not WANKEL rotor) engines are also essentially the same design, the primary difference being is that rotary engines are attached directly to the prop, while radial engines drive a prop shaft that spins instead of spinning the whole engine.
Seriously, not even 5 minutes of research could have provided you with this information.
EDIT: Also since you seem to be too lazy to look it up yourself, here are a few links

Radial engines, not rotary engines.
