| Summary: | The present invention relates to an apparatus as defined in the preamble of claim
, and a method as defined in the preamble of claim
, i.e. a method and an apparatus for charging a piezoelectric element.
Online optimization of injection systems having piezoelectric elements which are used, for example, as actuators in a fuel injection system of an internal combustion engine, wherein the piezoelectric element is activated by an activation voltage having a value set as a function of operating characteristics of the particular piezoelectric element, and based upon, for example, a correction value for injected fuel volume. |
