It is described a method for adapting injector characteristics of fuel injectors (30, 32) of a multi-cylinder internal combustion engine (10) having combustion chambers (12, 14) with direct fuel injection, which injector characteristics are adapted for each injector (30) individually to compensate for deviations the individual injectors (30, 32) have from standard injectors (30), wherein fuel is injected by each injector (30) and the operation of the engine resulting therefrom is evaluated, and wherein the method further comprises: determining for each cylinder a value of the peak pressure or the indicated mean pressure, which pressure value occurs during a combustion cycle in the cylinder's combustion chamber (12, 14), and modifying the injector characteristics individually for each injector (30, 32) to minimize differences between the pressure values over said cylinders. |
