摘要： When voltage changes occur in the battery used as a power supply in a fuel injection system, the amount of fuel injection also changes and the required amount of fuel injected cannot be obtained. To eliminate this problem, a fuel injector system is provided which has a fuel injection valve with at least one coil, a power supply, a power supply voltage detector, and a control unit for controlling the fuel injection valve. The control unit sets a reference value of a power supply voltages, and the above-mentioned fuel injection valve is controlled so as to obtain the required ampere-turns by reducing the resultant inductance of the coil when a power supply voltage detection value is less than the above-mentioned reference value, and the resultant inductance of the coil is increased when the power voltage detection value is greater than the reference value.

摘要： In a fuel injection valve used for an internal combustion engine, a valve closing lag time due to fluid resistance in a fuel path is shortened to decrease a minimum injection limit. More specifically, in the fuel injection valve in which an anchor is attracted to an end face part of a stationary core having a fuel path formed at a center part thereof by means of electromagnetic force, and in which a fuel injection hole is opened and closed by controlling a valve disc driven in conjunction with the anchor, there are provided a fuel reservoir part at a center part of an upper end face part of the anchor, a through hole extending axially in a fashion that an end part thereof is open to the fuel reservoir part, and a fuel path extending radially outward from the fuel reservoir part so that fuel is fed to a magnetic attraction gap between an upper end face part of the anchor and a lower end face part of the stationary core. Further, an opening part of a through hole that is open to an upper end face part of the anchor is at least partially opposed to a fuel introduction bore formed in the stationary core, and on the opening part of the through hole, a fuel introduction part is provided for capturing fuel running radially outward from a center side part of the anchor and for guiding the fuel thus captured to the through hole.

摘要： In relation to injectors used for internal-combustion engines, it is important to decrease valve closing delay time and also the minimum injection quantity, while these are affected by remanent magnetism in the fixed core, surface tension of the fuel, etc. With reference to a fuel injection valve with a pipe-shaped member to enclose a fixed core and a movable part and further with coils and yokes to cover up the above pipe-shaped member, the anchor to drive the movable member has a plurality of through holes for fuel passage extending in the axial direction, while these through holes are arranged at a certain intervals in the circumferential direction, and projections formed to constitute a contacting surface to touch the fixed core arranged randomly in between the through holes.

摘要： Using a swirl type fuel injection valve, a concentrated spray area and a thin spray area are formed, the position thereof are adjusted, and the spray is made to conform to the geometric shape of the engine and mounting position of the fuel injection valve, so as to reduce the fuel consumption and control the unburnt components in exhaust gas. The fuel injection valve is so constructed that a step is formed on the injection hole opening of the fuel injection valve, so as to provide two or more edge transition portions at the injection hole opening, resulting from the step, and the line connecting the edge transition portions forms an oblique angle relative to the wall formed by the step perpendicular to the injection hole center axis and the angled wall.
