A method of correcting a standard characteristic curve of a standard fuel injector (160) of an internal combustion engine (110), the standard characteristic curve representing a correlation between an energizing time during which the standard fuel injector (160) is energized and a fuel quantity injected by the standard fuel injector into a cylinder (125) of the internal combustion engine (110). The standard characteristic curve is used to inject metered quantities of fuel by said standard fuel injector (160), the method determines, from the standard characteristic curve, and for a reference energizing time, an associated injected fuel quantity, determines, from a master characteristic curve for the same energizing time, an associated injected fuel quantity, determines the difference between the master and standard curve quantities, calculates a correction value based on the difference and uses the correction value to adjust the standard characteristic curve. |
