Document Type and Number:
Japanese Patent JP2001132587
Kind Code:
A
Abstract:
To provide a fuel injection nozzle with a fine nozzle hole having a large L/D value and an easy manufacturing method for the fuel injection nozzle.
This fuel injection nozzle comprises a nozzle body section 2 made of an amorphous metal and a fine hole 3 formed at its tip section. A nozzle hole core 14 is arranged to form a fine nozzle hole 3 in a casting mold 11 for the nozzle body section 2. Molten metal M becoming amorphous metal by cooling at a critical cooling speed or higher is made to flow into a casting mold 15. Then the molten metal M is cooled at the critical cooling speed or higher to form the cast nozzle body section 2 made of amorphous metal.
