IPC: F02M61/18
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic fuel injection valve capable of uniformly spraying fuel by promoting atomization of fuel spray. SOLUTION: Because a fuel passage 31a is formed so as to extend obliquely in a gravity direction at a substantially the same angle with a seat surface 33a by avoiding a center shaft of a guide part 31 from the radial outside of the guide part 31 to the inside, eddy current is formed within space from the fuel passage 31a to an orifice 33b in pressurized fuel just before an injection from a nozzle hole 33c and fuel flow velocity is increased, when a valve member 29 leaves the seat surface 33a. Further, because the orifice 33b is formed on the center shaft of the guide part 31 so as to be thicker than the nozzle hole 33c in diameter, revolution of pressurized fuel is intensified nearer to the orifice 33c and revolving speed is further increased between the orifice 33b and the nozzle hole 33c.  Therefore, fuel injected from the nozzle hole 33c is increased in spray spreading angle, fuel collides with intake air just under the nozzle hole 33c at high speed and fuel spray is uniformly atomized.
