A method is disclosed to determine the opening degree of injectors in cylinders in a combustion engine with at least three cylinders, wherein the injectors are connected to a fuel accumulator in a common rail fuel injection system, the fuel supply to the fuel accumulator is interrupted, and subsequently a test injection of fuel is carried out into at least two and at most all except one cylinder at a time, in different combinations, at such a time that the injection does not cause any combustion in the cylinders. The pressure decreases caused in connection with the different test injections are measured, and the pressure decrease which is attributable to at least one specific injector is calculated based thereupon, which is used in the determination of the injector's opening degree. |
