Abstract (en)
[origin: DE10126686A1] The fuel injection system (1), for an internal combustion motor, has a pressure amplifier (4) with a sliding piston (6) which compresses the fuel from a low pressure zone (10) into a high pressure zone (9) to give the fuel its pressure to pass to the fuel injector (3). The piston stroke is controlled by the pressure in a pressure difference zone (7), to set the fuel pressure at the injector. A slit opening between the pressure difference zone and a leakage line (21), with an opening/closing piston, gives a cross section control of the outflow cross section from the difference pressure zone in two stages according to the stroke (h) of the pressure amplifier piston (6).
