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 (10; 61) with at least two different fuel pressures. A hydraulic pressure multiplicator (11) that generates the higher fuel pressure is provided in parallel to a by-pass line (19). Said pressure multiplicator (11) can be activated and deactivated via a valve unit (13). The invention provides a fuel injection system with an improved efficiency since the pressure multiplicator is not permanently operated and the losses through friction are reduced.
