Abstract
A fuel injection valve which injects fuel from a nozzle hole includes a cavitation generation flow path in which a cavitation bubble is generated in fuel flowing inside the injection valve, and a bubble storage flow path which is connected to the cavitation generation flow path and the nozzle hole and which stores the cavitation bubble generated in the cavitation generation flow path. A fuel containing the cavitation bubble stored in the bubble storage flow path is injected from the nozzle hole so that atomization of an injected fuel spray is enhanced.
