Abstract
In a method and a device for the calibration of internal combustion engines, in each fuel injector, at least one actuator element () may be activated by an electric signal interacts with at least one injection valve () having an injection rate for the supply of fuel to a combustion chamber () via injection holes, and in the case of a flow characteristic curve () of the fuel flowing through the injection holes deviating from a target characteristic curve () in a flow-time diagram, a signal characteristic curve () of the electric signal applied to the actuator element () is altered in a voltage-time diagram relative to a target characteristic curve () by a controller.
