摘要： A delay device for use with a fuel injector, the fuel injector having an electric controller for controlling the flow of a high pressure actuating fluid responsive to initiation and cessation of a pulse width command, the pulse width command defining the duration of an injection event, and an intensifier being in fluid communication with the controller, the intensifier being translatable to increase the pressure of a volume of fuel for injection into the combustion chamber of an engine; the delay device includes an apparatus, shiftable between a first disposition and a second disposition over a certain period of time after initiation of the pulse width command, the period of time effecting a delay in initiation of fuel injection after initiation of the pulse width command. A fuel injector including a delay device. A method of controlling a fuel injection event, includes the steps of flowing an actuating fluid from the controller to an intensifier responsive to a pulse width command, pressurizing a volume of fuel by means of the intensifier, flowing a high pressure fuel from the intensifier to an injector nozzle, and interposing a delay in at least a portion of the flow of fuel to the injector nozzle.
摘要翻译：一种与燃料喷射器一起使用的延迟装置，所述燃料喷射器具有电控制器，用于响应脉冲宽度命令的启动和停止来控制高压致动流体的流动，所述脉冲宽度命令定义喷射事件的持续时间，并且增压器与所述控制器流体连通，所述增压器可平移以增加用于喷射到发动机的燃烧室中的一定体积燃料的压力; 该延迟装置包括在开始脉冲宽度指令之后的特定时间段内可在第一布置和第二布置之间移位的装置，这是在开始脉冲宽度指令之后实现燃料喷射启动延迟的时间段。一种燃料喷射器，包括延迟装置。一种控制燃料喷射事件的方法包括以下步骤：响应于脉冲宽度命令将致动流体从控制器流动到增压器，通过增压器对一定体积的燃料加压，将高压燃料从增压器流动到喷射器喷嘴，并且在喷射器喷嘴的燃料流的至少一部分中插入延迟。
