ABSTRACT:
Method for manufacturing a cast iron cylinder block including steps of moulding the cylinder block with a cylinder wall formed with one or more protuberances in areas that will be subjected to piston side thrust forces so that the cylinder wall possesses a structure having more advanced growth of graphite in the aforementioned areas than in other areas, and thereafter removing the protuberance to form a cylinder bore. The cylinder block thus produced has a high ability of absorbing piston slap noise.
