Abstract: A fuel injector system designed to generate an ultra-high, injection pulse with an instant cut-off, the injector system including a distributor component for distributing high pressure fluid from a fuel supply to a fuel injector component and a connected booster component in which the high pressure fuel is increased in pressure to an ultra high fluid pressure by a piston mechanism having large diameter and small diameter pistons. The high pressure fuel hydraulically lifts a needle valve and is ejected through discharge nozzles at the end of the injector component. High pressure fuel in the injector component forces the reseating of the needle valve after fuel discharge.
