Abstract:
1. 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; wherein the information stored in the apparatus is ascertained by performing a plurality of consecutive injections having different activation times on the at least one fuel injector that define a plurality of test points of the at least one fuel injector, determining an actual injection quantity value at each one of the plurality of test points of the at least one fuel injector, and comparing the actual injection quantity value with a setpoint injection quantity value at each one of the plurality of test points of the at least one fuel injector, wherein the information stored in the apparatus includes activation times, wherein the information stored in the apparatus is used to determine an activation-time-correction map of the at least one fuel injector, and wherein the controller takes into account the activation-time-correction map of the at least one fuel injector to control the at least one fuel injector.
