  1. 2:17 8:17 Actually, no, the Wankel rotor doesn’t need to be a Reuleaux triangle. The curvature of the sides can be shaped to give a particular compression ratio. Remember, the rotor slides around the casing while spinning, it doesn’t roll, so the Reuleaux property is irrelevant. In fact, you can see the discrepancy between the curvatures of the Reuleaux and the actual rotor in that diagram at 2:17.
