  "textContent": "Disclosed is an electromagnetic fuel injection valve capable of reducing dynamic flow variation relative to the pulse widths of individual units in a lower pulse region than under idling conditions under which the dynamic flow is adjusted. Also disclosed is an internal combustion engine control device that utilizes the electromagnetic fuel injection valve. The electromagnetic fuel injection valve includes a fixed core 107, a coil 105 disposed at the periphery of the fixed core 107, an anchor 102 facing the lower end of the fixed core 107, a movable element with a valve seat 116 formed on its lower end, and a regulator 54 press-fit into a through-hole in the fixed core 107, the fixed core 107 being a central shaft of the electromagnetic fuel injection valve. The regulator 54 is adjusted so that a dynamic flow is high within a tolerance of ±x% of a target dynamic flow when a static flow Qst is high within a tolerance of ±y% of a target static flow while the dynamic flow is low within a tolerance of ±x% of the target dynamic flow when the static flow is low within a tolerance of ±y% of the target static flow.",
