ABSTRACT:
An injector system for injecting fuel and/or water into the combustion chamber of an engine cylinder having a high pressure pump with a primary piston for pumping fluid to an injector nozzle and plurality of integral control cylinders having means for discretely controlling the displacement of pistons in the control cylinders for altering the effective volume of fluid pumped by the primary cylinder, the fluid pumped hydraulically displacing an injector piston in the injector nozzle for displacing a nozzle discharge stem allowing a divergent spray of fuel and or water to enter the combustion chamber, wherein the high pressure pump includes an associated regulating mechanism for displacing at least one control cylinder piston according to an input derived from the operator's power demand and the engine r.p.m.
