Abstract:
A fuel injection system (1) for an internal combustion engine, in which fuel is injected into the combustion chamber of the engine at at least two different high fuel pressures via injectors (10), wherein fuel is supplied directly from a fuel pump to each injector at the higher of the two pressures, andeach injector (10) has a fuel line (15) for the fuel to be injected and a local diversion unit (11) located in the fuel line (15), which local diversion unit is activatable via a valve unit (12) to generate the lower of the two high pressures from the higher pressure within the local diversion unit, so that fuel is supplied to each injector at the higher of the two high pressures when the diversion unit is not activated, and at the lower of the two high pressures when the diversion unit is activated.
