Abstract
A device for correcting the injection behavior of at least one injector includes an apparatus for storing information relating to the at least one injector and means for controlling the at least one injector. The device takes the stored information into account in the correction, the information having been ascertained by comparing setpoint values with actual values individually at a plurality of test points of the at least one injector, the information being activation times for an activation time correction map of the at least one injector.

A device for correcting an injection behavior of at least one fuel injector, comprising:
- an apparatus for storing information relating to the at least one fuel injector;
- a controller for controlling the at least one fuel injector by taking into account the information stored in the apparatus;
- wherein the information stored in the apparatus is ascertained by comparing a setpoint value with an actual value at each one of a plurality of test points of the at least one fuel injector, and wherein the information stored in the apparatus is activation times for determining an activation-time-correction map of the at least one fuel injector.
A method for correcting an injection behavior of at least one fuel injector, comprising:
- ascertaining information relating to the at least one fuel injector, wherein the information is ascertained by comparing a setpoint value with an actual value at each one of a plurality of test points of the at least one fuel injector, and wherein the ascertained information is activation times for determining an activation-time-correction map of the at least one fuel injector;
- storing the ascertained information in a storage medium;
- and
- controlling, by a controller, the at least one fuel injector by taking into account the information stored in the storage medium.
