A rotary piston for a rotary piston, internal combustion engine, said rotary piston comprising a plurality of contiguous, convex, arcuate peripheral surfaces which, in combination with the engine housing, define combustion-working chambers. Each of the convex, arcuate peripheral surfaces of the rotary piston defines a convex, arcuate rotor recess having a radius greater than the radius of the arcuate peripheral surface of the rotary piston.
