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.
