摘要： In an injector used for an internal combustion engine, a favorable magnetic attraction force is obtained to reduce a controllable minimum injection amount of a fuel injection amount. In a fuel injection valve in which a fixed core and a moving element is contained inside a pipe-shaped member, and a coil and a yoke are provided on an outer side thereof, a space for placing the coil is placed so that an inner circumference length in a vertical section of the space becomes smaller than an outside diameter of the yoke, or a height of the space in an axial direction of the fixed core becomes smaller than a diameter of the fixed core.

摘要： To enable the inclination of the injection direction and the distribution of the penetration force of spray to be adjusted over a wide range, and an axially symmetrical spray shape to be obtained even when the injection hole is inclined, or the shape of the spray to be changed without inclining the injection hole, a fuel passageway 203 is provided as a swirling force adjustment means between the valve seat 201 and injection hole 101 of the fuel injector. This swirling force adjustment means adjusts the distribution of the swirling force of the fuel flowing into injection hole 101, and thus adjusts the spray shape obtained as a result.

摘要： A fuel-injection valve includes a fuel-injection hole, a valve element and a valve seat for opening and closing the fuel-injection hole, a force-applying member for applying force to the valve element in a direction of motion of the valve element, and a drive unit for applying force to the valve element in the direction opposite to that of the force applied by the force-applying member; wherein a secondary oscillation system, which interacts with a primary oscillation system including the valve element and the force-applying member, is added to the primary oscillation system, and the phase angle of force applied to the primary oscillation system by the secondary oscillation system is also staggered from that of force applied to the primary oscillation system, which is other than the force applied to the primary oscillation system by the secondary oscillation system, whereby the bouncing of the valve element during opening and closing of the valve is reduced, which in turn makes it possible to achieve very accurate fuel-injection control.
