Abstract
A method for manufacturing a cylinder having scavenging passages for a two-cycle internal combustion engine is disclosed which comprises the steps of forming bulged portions protruded radially outwardly in a portion of a cylindrical liner, and surrounding the liner by casting through a high pressure diecast method, thereby form a main part of the cylinder.
Claims2
