Patent ID: 7216624

Claim:
A fuel injection valve for injecting fuel into an internal combustion engine, the internal combustion engine including a cylinder, a cylinder head, and a piston, the piston being movable along a wall surface of the cylinder, the fuel injection valve-comprising: a nozzle that is located in the vicinity of the cylinder head, the nozzle having a plurality of nozzle holes, wherein each of the plurality of nozzle holes is defined in such a manner that: each nozzle holes is opposed to an in-cylinder space defined in the cylinder; each nozzle hole has an imaginary injection line that extends from each nozzle hole into the in-cylinder space; the imaginary injection line is directed toward one of an upper surface of the piston and the wall surface of the cylinder; the in-cylinder space includes a plurality of divided spaces each including the nozzle and at least one imaginary injection line; the plurality of divided spaces includes a piston-side divided space and a head-side divided space; the piston-side divided space is adjacent to the piston; the head-side divided space is adjacent to the cylinder; and the head-side divided space contains fuel and air mixed at an air fuel ratio, which is greater than an air fuel ratio of fuel and air in the piston-side divided space.
