Title:
PISTON FOR INTERNAL COMBUSTION ENGINE AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2016/175448
Kind Code:
A1
Abstract:
The present invention relates to a piston for an internal combustion engine and a method for preparing same, the piston reciprocating inside a cylinder of an internal combustion engine and receiving high-temperature and high-pressure explosion pressure during combustion, thereby transmitting power to a crankshaft by means of a connecting rod. In order to enable easy removal of a core inserted into a body after casting of the body, a piston can comprise: one or more core discharge portions which are formed on one side of a cooling channel and from which a core melted by means of a melting material is discharged; and one or more covers which are formed in a shape corresponding to the shape of the core discharge portions, are inserted into the core discharge portions, and have formed thereon a refrigerant hole part through which a refrigerant can flow in from or discharge out to a refrigerant flow path of the cooling channel.
