Internal combustion engine apparatuses, systems and methods. The internal combustion engine system includes a cylinder block including a cylinder bore and a piston movably positioned in the cylinder bore. The piston is configured to slide in an axial direction within the cylinder bore. The piston includes a piston crown and a turbulence induction protuberance extending in an axial direction from the piston crown. The turbulence induction protuberance is positioned radially intermediate an axial center of the piston and a circumferential portion of the piston. The turbulence induction protuberance is configured to cause turbulence in a propagating flame propagating from a central region of the cylinder bore to cause the propagating flame to extend to a circumferential portion of the cylinder bore.
