Title:
シリンダブロックの製造方法
Document Type and Number:
Japanese Patent JP4131371
Kind Code:
B2
Abstract:
A cylinder block production method is characterized by having, as a step prior to a cast-enclosing step of cast-enclosing a cast iron-made cylinder liner within a cylinder block body, an erosion-wash step of washing an outer peripheral wall surface of the cylinder liner and eroding a portion of a base structure of the cast iron forming the outer peripheral wall surface of the cylinder liner so as to form many small protrusions on the outer peripheral wall surface by jetting a high-pressure fluid onto the outer peripheral wall surface of the cylinder liner, in order to improve strength of adhesion between the cylinder liner and the cylinder block body. Since the base structure is partially eroded, complicated-shape small protrusions can be formed. Furthermore, sand and a mold release agent adhering to the outer peripheral wall surface of the cylinder liner can be removed. Therefore, the adhesion strength will improve.
