<p>A method and a system for analysis of a function for at least one injection device 131...13N in a combustion engine is described. Spin-down times T1...TN related to injection devices in an engine are first determined. Subsequently, an adjustment device 144 performs an adjustment of the original amount Mpredet of fuel which is supplied to the respective cylinder, if at least one spin-down time of the determined spin-down times T1...TN differs from a spin-down time interval Tpreciet_1...Tpredet_N for the corresponding injection device. The adjustment, which is performed by the adjustment device for each one of the injection devices with a diverging spin-down time, is performed in accordance with an iterative algorithm, until an adjusted diverging spin-down time Tacijust_1....Tadjust_N for the injection device reaches the spin-down time interval TPreciet_1-Tpredet_N. Subsequently, an adjusted amount MadjUSt_1...Madjust_N of fuel, which is related to the adjusted spin-down time Tadjust_1-Tadjust_N, which is obtained with the use of the iterative algorithm, is determined.</p> |
