Abstract
A fuel injection system includes a pressure booster having a displaceable piston which can be subjected to pressure via a pressure booster chamber on the low-pressure side for compressing the fuel in a pressure booster chamber on the high-pressure side to be delivered to an injector. The stroke of the piston is controllable by the pressure in a differential chamber of the pressure booster and is used to vary the fuel pressure delivered to the injector. Means for continuously variable definition of the inlet cross section to the pressure booster chamber of the pressure booster on the low-pressure side or of the outlet cross section from the differential chamber of the pressure booster are provided.
