Title:
FUEL INJECTION VALVE AND INTERNAL COMBUSTION ENGINE LOADED WITH THE SAME
Document Type and Number:
Japanese Patent JP2003148299
Kind Code:
A
Abstract:
To provide a fuel injection valve improved in atomization by effectively increasing an injection flow speed and effectively forming a eddy current in the upstream of an injection hole and making fuels collide with each other outside the injection hole, and to provide an internal combustion engine loaded with the same.
The wall of an external peripheral fuel radiation chamber 201 opposite to a plate member 111 is formed into an inclined wall surface 202 to form a flow passage cross sectional area smaller, as a fuel flows in the peripheral direction. Or, the wall surface of the external peripheral fuel radiation chamber 201 opposite to the upstream of the plate member 111 is provided with a stage difference 601 to form a eddy current 701.
