Abstract
In a circuit arrangement () for operating an injector arrangement () for injecting fuel in an internal combustion engine of a motor vehicle, in order to obtain information easily as to the degree to which each valve is open when the injector arrangement is in operation, a measuring signal (S) is superposed on a control voltage that is supplied to an actuator (Cpiezo, Rpiezo) and, based on an evaluation of the electrical properties of the actuator (Cpiezo, Rpiezo), a detection signal (S) is produced that is representative of the position of the valve body () relative to the valve seat ().
