    Abstract: An object of the present invention is to provide a fuel injector which can promote convergence of a motion of a valve body while a valve is opened and promote stabilization of an injection amount. In the present invention, a fuel injector includes a movable iron core 404, a fixed iron core 401, a first spring member 405, a second spring member 406, contact portions 102c and 404b′, and a gap g1. The movable iron core 404 is provided relatively displaceable to a valve body 102. The fixed iron core 401 is opposed to the movable iron core 404. The first spring member 405 energizes the valve body 102 in a valve closing direction. The second spring member 406 energizes the movable iron core 404 in a valve closing direction. The contact portions 102c and 404b′ are in contact with each other in a case where the movable iron core 404 displaces in a valve opening direction with respect to the valve body 102. The gap g1 is formed between the contact portions 102c and 404b′ in a valve closing state. In a state in which the movable iron core 404 and the valve body 102 move in different directions after the movable iron core 404 collides with the fixed iron core 401 while a valve is opened, a spring force is not applied between the movable iron core 404 and the valve body 102.

In an electromagnetic valve control unit for controlling opening/closing of an electromagnetic valve by a drive voltage and a drive current to be applied, the drive voltage and the drive current applied to the electromagnetic valve are corrected on the basis of a detection time of an inflection point from time series data of the drive voltage and the drive current when the electromagnetic valve is opened/closed.

    Abstract: In a fuel injection valve, it is possible to obtain spray in which the penetrating force of injected fuel is suppressed.The fuel injection valve includes a valve seat that forms a gap with a valve body, the gap allowing fuel to pass therethrough, and multiple injection holes that are located further downstream from the gap. The fuel to which pressure is applied flows out from the injection holes.When the flow velocity of the fuel in the gap formed between the valve body and the valve seat is indicated by meters per second, the flow velocity is set to be greater than a value obtained by multiplying the square root of the pressure applied to the fuel by 28. In this manner, the flow velocity in the gap increases, and flow velocity distribution inside the injection hole is uniformized, thereby suppressing an increase in penetration.
