Wankle engines actually don't use a true reuleaux triangle for a rotor profile. A Reuleaux triangle is composed of three 60 degree arcs with centers on the opposite corners. Wankle rotors use an arcs less than 60 degrees with centers beyond the opposite corners. This is important to note because while a Reuleaux triangle is a shape of constant width, a Wankle rotor is not.
