Method for learning a minimum actuation duration of fuel injectors of an internal combustion engine

A method for learning and determining a minimum injector-specific electric actuation duration for at least one fuel injector of an internal combustion engine of a motor vehicle. Starting with a predefined electric actuation duration which definitely does not result in an injection, the electric actu...

Beschreibung
Zusammenfassung:	A method for learning and determining a minimum injector-specific electric actuation duration for at least one fuel injector of an internal combustion engine of a motor vehicle. Starting with a predefined electric actuation duration which definitely does not result in an injection, the electric actuation duration is gradually increased in each engine stop and/or in each engine start in successive engine stops and/or in successive engine starts of the internal combustion engine up to an actuation duration in which an injection with a combustion occurs, and then this actuation duration may be determined as the minimum electric actuation duration. The invention also relates to a corresponding device.
