Abstract
The present invention provides a cylinder head-integrated cylinder block in which assembly is easy and a thickness of an aluminum member is not increased even if an integral cylinder head is molded by using the aluminum member and which is lightweight and has strength at a high temperature and a process for manufacturing the cylinder head-integrated cylinder block. A cylindrical cup-shaped member with a bottom is molded of reinforced aluminum material having heat resistance and wear resistance, a cylinder head portion and a cylinder block portion are molded as an integral body by molding the molded cup-shaped member in casting aluminum material by enveloped casting, and the cylinder block portion in which the cup-shaped member is molded by enveloped casting is pressurized under a condition of a temperature at which a material characteristic of the reinforced aluminum material constituting the cup-shaped member does not change, thereby providing a cylinder head-integrated cylinder block in which the cylinder head portion having an intake port and an exhaust port and the cylinder block portion whose end face opening is closed by the cylinder head portion are integrated.
