Title: Method of correcting a standard characteristic curve of a standard fuel injector of an internal combustion engine

Abstract: A method and controller provide a corrected standard characteristic curve for a fuel injector to inject fuel into an internal combustion engine. A minimum fuel injector energizing time is determined where a predetermined parameter based upon a plurality of fuel injector energizing times and a plurality of master fuel injector energizing times is a minimum. An energizing time correction value is the difference between a reference energizing time and the minimum energizing time. The standard characteristic curve is corrected based on the energizing time correction value.
