  • Method of manufacturing cylinder head
    Patent number: 7100671
    Abstract: In a method of manufacturing a cylinder head having a partition plate for an intake port, there is prepared a partition plate having an intake-side distal end and a cylinder-side distal end. The partition plate is located in a core to form the intake port and molten metal is supplied to a periphery of the partition plate. After solidifying the molten metal, the core is removed. At least the intake-side distal end of the partition plate is located in an expansion-permit space that permits thermal expansion of the partition plate caused by heat of molten metal.
