Abstract
A device and a method for monitoring an interval between a first injection operation and a second injection operation of a combustion cycle in a cylinder of an internal combustion engine are described, in which it is determined whether an electrical actuator element has fully opened after the first injection operation and in which it is determined whether energizing sequences of the electrical actuator element overlap. Then, the interval between the first injection operation and the second injection operation is modified as a function of the determination results of the preceding determination operations.
