Title:
CYLINDER BLOCK OF ENGINE AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JPH08177614
Kind Code:
A
Abstract:

PURPOSE: To cast the cylinder block of an engine by using a die casting method.

CONSTITUTION: One or plural substancially cylindrical inserts 151 made by die casting are arranged in line to form a insert line body 15. The inner peripheral wall 152 of the insert line body 15 is fitted in a mold for a cylinder block body 14 to be inserted. After that, a cutting work is executed to the thickness of the insert line body 15 from the inner peripheral wall 152 for forming a hollow domain 20 in the inside of the insert line body 15. A cylinder liner 16 is fitted in the insert line body 15 from its end part to shut the hollow domain 20 for forming a water jacket 21. Since a cutting work is executed to the die- cast insert line body 15, an inside shrinkage cavity or the like is exposed, but the cylinder block body 14 and the insert line body 15 stick fast to each other through a unmachined surface to secure sealing properties on a boundary face between. Therefore the cylinder block of a closed deck wet liner type engine having no trouble such as the leakages of water and oil can be manufactured.
