摘要： A fuel injection controller includes an increase control portion applying the boost voltage to the coil to increase a coil current to a first target value, and a constant current control portion applying a voltage to the coil to hold the coil current to a second target value. A threshold is an energization time period that is necessary to reach a boundary point between a seat throttle area of a property line and an injection-port throttle area of the property line from an energization start time point. An initial-current applied time period is from the energization start time point that the boost voltage starts to be applied to the coil to a time point that the coil current is decreased to the second target value. The increase control portion controls the coil current such that the initial-current applied time period is less than the threshold.

摘要： Injectors and solenoid valves incorporating actuators with kinetic energy transfer armatures. A fuel injector includes a longitudinally extending injector body and a valve supported in the injector body. The valve is configured for longitudinal movement within the injector body. An armature is connected to the valve and an impact member is disposed between the armature and a solenoid, and moveably connected to the armature. The solenoid is operative when energized to sequentially move the impact member and armature toward the solenoid, thereby actuating the valve. The fuel injector further includes a return magnet located adjacent the armature and opposite the solenoid, wherein the return magnet is operative to maintain the valve in a closed position when the solenoid is not energized.

摘要： A dual-coil outwardly-opening fuel injector including a fuel tube connected at a lower end to a lower injector housing. Within the fuel tube are a lower (opening) solenoid pole piece, a specially-formed armature, and an upper (closing) solenoid pole piece. A seat assembly including an injector nozzle, swirler, and valve seat are adjustably threaded into the lower housing. A pintle assembly, including a solid pintle portion supporting a valve head and a tubular portion welded thereto, is axially disposed within the fuel tube and is welded to the armature which is spaced from the lower pole piece by a distance equal to the opening stroke of the valve. A return spring adjustment mechanism disposed on the upper pole piece engages the upper end of the pintle assembly for varying the closing force of the return spring. Opening and closing solenoid preassemblies are mounted external to the fuel tube for magnetically engaging the pole pieces and armature within in known fashion.

摘要： An electromagnetic fuel injection valve in an engine injects fuel by opening/closing a fuel flowing path with a valve element. A controller controls opening/closing of the fuel flowing path and changes magnetic force generated by a control coil driving the valve element so that the magnetic force is less during a valve open state-holding period than at an initial valve-opening time. The controller detects the voltage of a battery and applies the voltage fed from the battery to the control coil, while changing a time interval (Tc), for which current is passed through the control coil, based on the detected voltage, in order to change the magnetic force, without raising the voltage from the battery. The controller also detects increase/decrease of a pressing force on the valve element caused by fuel pressure and changes the time interval (Tc) accordingly.

摘要： In an electromagnetic fuel injector, when an opening valve pulse is turned ON by a command from an ECU, a first coil is energized and a first fixed core attracts a moving core and unseats a valve member from a valve seat to open a valve of the fuel injector. A time Tx before the opening valve pulse becomes OFF, a closing valve pulse is turned ON, whereby a second coil is energized and a second fixed core attracts the moving core toward a valve closing direction. As a result, after the valve starts to close, the urging force in the valve closing direction increases rapidly, the time delay from the start of valve closing to the end is shortened, and the valve closing responsiveness improves.

摘要： The present invention provides a fuel injector with an armature and a means for biasing the armature toward a first position. A primary coil is wound in a first direction such that, when energized, it develops a magnetic force that opposes the biasing means and causes the armature to move from the first position to a second position. A secondary coil is positioned coaxially with the primary coil. The secondary coil has an at least partially reverse wound portion wound in a second direction opposite the first direction, such that the magnetic field generated by the at least partially reverse wound portion at least partially cancels the magnetic field of the primary coil.

摘要： A solenoid actuator, adapted for use in a fuel injector, has a pole member, an armature associated therewith, and an energizable winding associated with the pole member. The solenoid actuator is latchable by residual magnetism between the pole member and the armature without the aid of a permanent magnet. The pole member and the armature are composed of steel having a carbon content of between 0.8% and 1.2% and an RC hardness of between 40 and 60. The armature is reciprocable between a first position in which the armature makes physical contact with the pole member and a second position in which the armature is spaced from the pole member. The armature occupies the first position when the winding is energized and the second position when the winding is deenergized. The armature is held in the first position by residual magnetism between the pole member and the armature when the winding is deenergized after being initially energized. The actuator may also be embodied in the form of a dual-acting actuator having an armature and first and second pole members. The armature and pole member(s) of the actuator may be formed via a heat treating method which is based on the recognition of the relationship between the hardness of the pole member(s) and armature and the resultant residual magnetism of those components.
