ABSTRACT:
A fuel injection system for an internal combustion engine, comprising cylinder which has a delivery plunger slidable therein, an injection plunger which is hydraulically actuated by the delivery plunger and which defines an injection pump chamber, a timing plunger which defines a timing pump chamber selectively connected to a drain and which is hydraulically actuated by the delivery plunger to control the connection of the timing pump chamber to the drain, a controllable electromagnetic control valve, balance timing orifice, non-return valve, fuel passage and metering groove feeding the fuel into the injection and timing pump chambers, and nozzle for injecting the fuel delivered by the injection pump chamber, the injection plunger and timing plunger being axially displaced by the fuel fed into the respective pump chambers, in directions opposite to the directions of the movement of the two plungers caused by the delivery plunger, through a stroke in proportion to the amount of the fed fuel.
