Abstract (en)
[origin: DE19910976A1] The invention relates to a fuel injection system for an internal combustion engine comprising at least two different high system pressures, whereby a first pressure accumulator (4) which is supplied by a first pump (3) is provided for the lower system pressure, and a second pressure accumulator (7) which is supplied by a second pump (6) is provided for the higher system pressure. At least the second pressure accumulator (7) can be connected via a line to the injectors (10) of the individual cylinders of the internal combustion engine. The second pump (6) is connected on the entry side to the first pressure accumulator (5).
