Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide: a member for an internal combustion engine which sheds deposit while evaporating liquid fuel which has adhered, that is, which can rapidly evaporate the liquid fuel which has adhered and prevent adhesion of the deposit; a piston, a valve and a fuel injection valve each utilizing the member; and a production method of the member for an internal combustion engine. SOLUTION: The member for an internal combustion engine comprises a substrate on which a carbon coating film is formed, the carbon coating film containing fluorine and having a thickness of 10 μm or less. The member includes an intermediate layer containing carbon and silicon between the substrate and the carbon film coating. The piston utilizes the member for an internal combustion engine, the piston being provided with carbon coating film on its crown surface. The valve utilizes the member for an internal combustion engine and is provided with carbon film coating on its stem portion, head portion, surface on the side of a combustion chamber or the like. The fuel injection valve utilizes the member for an internal combustion engine, the injection hole of which is provided with carbon film coating. The member for an internal combustion engine is produced by coating the carbon film coating by a gas-phase film forming method. COPYRIGHT: (C)2006,JPO&NCIPI
