Abstract

The invention is directed to a method and an arrangement for synchronizing at least two power-adjusting elements of an internal combustion engine which are electrically driven independently of each other. For carrying out the synchronization, the intervals between the respective combustions or the corresponding segment times of at least two cylinders are detected to which individual power-adjusting elements are allocated and their deviation is determined. At least one power-adjusting element is adjusted in order to maintain this deviation within a pregiven tolerance band. A correction of the control of the power-adjusting elements is derived in dependence upon the adjustment. The power-adjusting elements are adjusted in mutually opposite directions.
