Abstract
A method for operating a fuel injection system of an internal combustion engine is described in which pressurized fuel is provided in a pressure storage device and a fuel pressure prevailing in pressure storage device is regulated with the aid of a pressure regulation, during a first measuring interval at least one fuel withdrawal from the pressure storage device taking place, and during a second measuring interval no fuel withdrawal from the pressure storage device of this type taking place, and during the first and the second measuring intervals a performance quantity of the pressure regulation being ascertained in each case, and the fuel quantity withdrawn during the first measuring interval being ascertained for the at least one withdrawal from a difference of the ascertained performance quantities of the pressure regulation.
