Yup, that too! This engine probably has it's challenges (like sealing the rotor) but it has several big advantages over reciprocating piston engines.

Another HUGE advantage is the force vectors of the power stroke coming just after TDC means that the most power is available at an awkward position of the con rod and the crank journal. No need to compromise the geometry by shifting the crank center - which improves the power stroke, but hurts the compression stroke.
