| The invention relates to a fuel injection system for combustion engines that has a high-pressure part and a low-pressure part. In the high-pressure part, fuel is supplied from a fuel tank to a high-pressure accumulator (5) via a high-pressure pump (4) and a high-pressure line (32). Injectors (7) are supplied from the high- pressure accumulator (5) via high-pressure supply lines (6). In the low- pressure part, the injectors (7) are connected to a low-pressure accumulator (9) via injector return lines (8) whereby, in the low- pressure accumulator (9), a pressure greater than or equal to 50 bar is maintained by a pressure maintaining valve (11). When a pressure inside the low-pressure accumulator (9) exceeds the opening pressure of the pressure maintaining valve (11), the fuel is returned into the fuel tank via a return line (12). The low-pressure accumulator (9) is connected to the high-pressure line (32) of the high-pressure part via an overflow valve (15) and an overflow line (33). | ||||||

| The invention concerns a fuel injection valve, comprising a valve body (10), a control pressure chamber (16) formed therein that is closed on one side by an actuating element (14) for a valve needle (12), said needle being controlled by the actuating element and movable between a closed position and an open position, an inlet (18) to the control pressure chamber and an outlet (20) from the control pressure chamber, which is controlled by a control valve (24). The invention aims at enabling a partial opening stroke of the valve needle, wherein the amount of injected fuel is dosed in a highly precise manner. To this end, a movable throttle piston is provided that, in a first position, enables a partial opening stroke of the valve needle from the closed position against little resistance and which, in a second position, enables a residual opening stroke of the valve needle (12) into the opening position following the partial opening stroke but only against greater resistance. | ||||||

| A fuel injection valve control device controlling a fuel injection valve that injects a fuel into a combustion chamber includes an operation-condition calculation portion that calculates a fuel injection condition of the fuel injection valve based on a crank angle detected by a crank angle sensor that detects the crank angle of an engine, a current-waveform setting portion that sets a current waveform of a current supplied to the fuel injection valve on the basis of the fuel injection condition calculated by the operation-condition calculation portion, and so on. The current-waveform setting portion sets the current waveform so as to set a temporal change of a pickup current of a needle provided in the fuel injection valve to be equal to or less than a predetermined reference value when a fuel injection start timing is equal to or more than 180 degrees BTDC. The current-waveform setting portion sets the current waveform so as to set a temporal change of the pickup current of the needle to be more than the predetermined reference value when the fuel injection start timing is smaller than 180 degrees BTDC. | ||||||
