ABSTRACT:
In an internal combustion engine, the fuel enters at least one combustion chamber of the internal combustion engine via at least one fuel injection device. A piezoelectric actuator moves a valve element of the fuel injection device. The function of the piezoelectric actuator is monitored and a malfunction is detected. To minimize the risk of damage to the internal combustion engine in the event of a malfunction of the piezoelectric actuator, the fuel mass flow to the fuel injection device is reduced if a malfunction of the piezoelectric actuator is detected.
