| 简介 |
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. |
