Abstract
A rotor for a rotary internal combustion engine with a first face seal biased axially outwardly away from the first end face has opposed curled ends abutting a first end seal of a respective one of the adjacent apex portions, and a second face seal biased axially outwardly away from the second end face has opposed curled ends abutting a second end seal of a respective one of the adjacent apex portions. A rotary internal combustion engine and a method of sealing chambers of a Wankel engine are also discussed.
