Rotary != Wankel.

Accepted definitions are a bit vague, often having Wankel engines as
alternative meanings for "rotary". However, I doubt you'd want a true
rotary engine under your bonnet ;-)

Isn't the original meaning an engine with a stationary crankshaft which
the rest rotates round? Although it does seem to mean a Wankel these days.

Radial is the word our friend was searching for.
