摘要:
Fuel injection valve with conical valve seat surface that abuts a valve body to seal fuel, fuel injection orifices having an inlet opening formed on the valve seat surface, wherein fuel sprays injected from the plurality of fuel injection orifices include a first fuel spray constituted by a fuel spray injected from at least one fuel injection orifice and a second fuel spray constituted by a plurality of fuel sprays injected at an outer periphery of the first fuel spray, and a fuel injection orifice that injects the first fuel spray constituted with a plane that includes an orifice axis connecting a center of an inlet with a center of an outlet of the fuel injection orifice, parallel to a center axis of the fuel injection valve intersecting a plane, a conical apex that forms the valve seat surface to form an inclination angle that is larger than 0°.
