Abstract
An accumulator injector employs a shuttle piston assembly to produce a pilot injection prior to the primary fuel injection of the injector and to control the injection rate. The shuttle piston communicates with the control chamber and the accumulator chamber of the injector to provide a controllable pressure bleed means for controlling the valve needle lift of the injector.
