摘要： A method of minimizing the cold start delay and impact fatigue of an actuator includes calibrating the actuator by initially raising the temperature to a desired operating temperature through induction heating of the actuator rod. Additionally, a control system for a magnetostrictive actuator includes a rod of magnetostrictive material, a solenoid coil wrapped at least once around said rod, and a controller operatively connected to said solenoid coil wherein the controller detects an impact of the rod with another surface and adjusts the operation of the actuator to minimize the potential for additional future impacts. The rod may be segmented and include end caps to further reduce the potential for impact fatigue.

摘要： An apparatus for injecting fuel into a combustion chamber of an internal combustion engine. The apparatus includes a solid magnetostrictive material with a favored direction of magnetostrictive response formed into a shape with ends that are substantially parallel to each other and substantially perpendicular to the favored direction of magnetostrictive response. A fuel control valve element is located coaxial to the favored direction of magnetoelastic response of the magnetostrictive material, the element opening inwardly. A solenoid coil is located concentric with the magnetostrictive material and coaxial to the favored direction of magnetoelastic response, the solenoid coil adapted to excite the magnetostrictive material into mechanical motion. An excitation signal is provided within the solenoid coil consisting of a signal, before a main current signal, sufficient to cause magnetic domain alignment but not rotation, and finally a magnetic return path circuit is provided in magnetic communication with the solid magnetostrictive material.

摘要： A programmable diesel fuel injector that increases frequency response and control precision over desired fuel flow rates throughout each injection event. All valve frequency and motional requirements are met by a compensated direct drive, which is enabled by the durable capability of a rare earth alloy to lengthen in a magnetic field. A continuously variable electrical input waveform is predetermined to result in the desired fuel injection rate shape. A magnetostrictive transducer converts voltage and current into continuously variable force and displacement of a master piston acting upon fuel within a closed chamber. A slave piston responds to the fuel pressure changes within the closed chamber and acts upon the spool of a spool valve to eject fuel.
