摘要

The invention relates to a fuel injection system (1) comprising a pressure intensifying unit (9) arranged between a pressure accumulation chamber (6) and a nozzle chamber (16). The pressure chamber (14) of the pressure intensifying unit is connected to said nozzle chamber (16) via a pressure line (20). In addition, a bypass line (28) is provided which is connected to the pressure accumulation chamber (6). The bypass line (28) is directly connected to the pressure line. The bypass line (28) can be used for to effect pressure injection and is arranged parallel to the pressure chamber (14) so that the bypass line (28) can be passed through regardless of the movement and position of a displaceable pressure means (12) of the pressure intensifying unit (9). The inventive fuel injection system increases the versatility of injection.
