FUEL INJECTION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a fuel injection system (1) for an internal combustion engine. According to the inventive system, the fuel is injected into the combustion chamber of the internal combustion engine via injectors (8) with at least two different fuel pressures. The injection system further comprises a central distributor (10) that distributes the fuel to the individual injectors (8) and a central pressure accumulator (6) for the lower fuel pressure. One valve element (13) each that switches between the two fuel pressures is centrally provided for every injector (8) The central distributor (10) for the higher fuel pressure is mounted parallel to the central pressure accumulator (6) for the lower fuel pressure.
