Title:
FUEL INJECTION VALVE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2008019773
Kind Code:
A
Abstract:
To provide a technique to suppress adhesion of oil and accumulation of deposits to the vicinity of the injection hole of a fuel injection valve by a simpler structure.
A trumpetlike projection part 13 to foster generation of different gas flow (for example, Karman's vortex) when a fuel mist flow is passed through, is provided to the fuel injection hole 16 in the nozzle of the fuel injection valve. Draft such as Karman's vortex is thereby positively generated in fuel injection, and fuel droplets adhering to the vicinity of the injection hole 16 are easily moved therefrom and hardly deposited thereto by this strong gas flow.
