A fuel injection system (1) for internal combustion engines has at least one stroke-controlled injector (10). A pressure booster (9) that has a movable piston (26) is connected between the at least one injector (10) and a high-pressure working medium source (5). The movable piston (26) divides a primary chamber (13), which can be connected to the high-pressure working medium source (5), from a pressure chamber (8) that communicates with the at least one injector (10) and is filled with fuel. The pressure booster (9) generates a first fuel system pressure in the injector (10), which is used for the injection. The fuel injection system (1) has means for furnishing a further, second fuel system pressure, and these means can be used for injection without activating the pressure booster (10).
