ABSTRACT:
In the embodiment described in the specification, the fuel injection quantity for an internal combustion engine is adjusted for regulating smooth operation by recording a number of uneven operation fuel injection values for each individual cylinder during an observation interval, sorting the recorded uneven operation values individually for each cylinder operation according to their sign and magnitude, determining, individually for each cylinder, whether the median uneven operation value is lower than, equal to, or higher than zero, and increasing the injection quantity if the median uneven operation value is lower than zero, or reducing the fuel injection quantity if the median uneven operation value is higher than zero.
