Adaptation method of an injector of an internal combustion engine

An adaption method of an injector of an internal combustion engine, in which an actually injected fuel quantity is adapted to a target injection quantity, may include: actuating the injector using a test injection pulse in at least one segment of an injection cycle; detecting a change in the rotatio...

Zusammenfassung:An adaption method of an injector of an internal combustion engine, in which an actually injected fuel quantity is adapted to a target injection quantity, may include: actuating the injector using a test injection pulse in at least one segment of an injection cycle; detecting a change in the rotational speed signal due to the test injection pulse in the segment associated with the test injection pulse; and correcting the injected fuel quantity based on the detected change in the rotational speed signal, wherein the method is performed during a normal operating state of the internal combustion engine.
