Abstract (en)
[origin: DE19910971A1] 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 high-pressure pump (3) is provided for the higher system pressure and a second pressure accumulator (6) is provided for the lower system pressure. At least the first pressure accumulator (4) can be connected via a line to the injectors (10) of the individual cylinders of the internal combustion engine in order to effect a fuel injection. The pressure level of the high-pressure pump (3) is greater than the higher system pressure and the first pressure accumulator (4) has a first pressure control valve (5) leading to the second pressure accumulator (6), and the second pressure accumulator (6) comprises a second pressure control valve (7).
