Title: Method of preoducing cylinder for two-cycle engine
Inventor: SUZUKI TETSUYA
IPC: F02B75/02
Filed: 1978-05-22
Abstract: PURPOSE:To produce cylinders for two-cycle engine efficiently in mass production by integrating to cast the scavenging port portion of a cylinder as a shell piece into a modular construction, inserting the shell piece and casting the cylinder body by means of a casting process by pressure metallic mold. CONSTITUTION:Casting sand prepared by mixing and kneading inorganic binder with sand is used to fill and rap in a core for forming a scavenging port cavity to thereby form a sand core. The core thus formed is set at a scavenging port shell piece casting GDC mold, and molten metal is charged into the mold to thereby obtain a composite scavenging port shell piece 1. This piece 1 is set in a cylinder casting DC mold, and molten metal is press-charged through a DC machine into the DC mold to thereby insert the piece 1 so as to thus cast a cylinder body 4. In this case, since the sand core 2 retained in the piece 1 as it is operates as a reinforcing material, the molten metal may not damage due to high pressure upon press-charging thereof into the DC mold but can be inserted with the piece 1 safely.
