Abstract

A method for controlling the displacement of a stack (2) of a piezoelectric actuator (1) for use in a fuel injector comprises determining a desirable amount of charge (”Q) to be added or removed from the stack (2). The method further comprises selecting a drive current level (PO, SO) and a drive time (t open , t close ) in accordance with the desired amount of charge (”Q) and an operating parameter, and driving the drive current through the stack (2) for the drive time (t open , t close ) in order to add or remove the desired amount of charge (”Q).
