Abstract:
In a processing method for processing a cylinder block, a finish processing for the cylinder bore is performing, by pressing the portion of the bolt phase for fastening the cylinder head on the cylinder portion outer peripheral surface forming the inside surface of a water jacket, on the condition that the rigidity of the pressed portion on the cylinder portion toward the pressure from the side of the cylinder bore (the surface pressure from the grinding stones by honing process) is enhanced compared with the other portions.
