Abstract:
A perforation method and an perforation apparatus in which a hollow member of a fuel injection nozzle is filled with a filler such as a zirconia ball, and a laser light is applied to the hollow member to form an injection hole while vibrating the zirconia ball using an ultrasonic vibrator. After the injection hole is formed, the laser light is introduced through the injection hole to the inside of the fuel injection nozzle, and thereby is applied to the vibrated zirconia ball.
