摘要
An apparatus for variably controlling the fuel flow characteristics of a hydraulically-actuated injector during an injection cycle. The apparatus includes variable control of actuating fluid pressure and a spill control apparatus associated with the plunger and barrel assembly of the injector. The apparatus can control the initial rate of fuel injection and also provide continuous or split injection throughout the load and speed range of an engine. Performance is controlled by the geometry of the spill control apparatus along with the variably controlled pressure of the actuating fluid supplied to the injector. The apparatus helps reduce engine noise and emissions.
