ABSTRACT:
A fuel injection device (26) for an internal combustion engine (10) has a fuel inlet (40) and a fuel outlet (42). A plunger (58) is operable within a fuel pumping chamber (50) for forcing pressure-amplified fuel to open and pass through an outlet control valve (56) at the outlet. A (“fast-acting”) control valve (64) operates in timed relation to the engine cycle to allow control fluid from an oil rail (34) to force valve (56) closed when fuel is not to be injected and to disallow control fluid from forcing valve (56) closed when fuel is to be injected. A (“slow-acting”) control valve (72) is selectively operable in timed relation to the engine cycle to disallow control fluid from acting on plunger (58) when fuel is not to be injected, but allow control fluid to act on the plunger to force injection when control valve (72) is disallowing control fluid from forcing control valve (56) closed.
