Abstract (en)
[origin: EP1138919A1] Fuel injection system and method for operating the fuel injection system, in which a piezoelectric element drives a valve for closing a pressurized fuel supply line by applying a voltage to said piezoelectric element, wherein the voltage necessary to close the pressurized fuel supply line is determined based upon the gradient or the derivative over time of the pressure in the pressurized fuel supply line. <IMAGE>
