Method of controlling internal combustion engine, control arrangement, internal combustion engine, and vehicle

A computer program product stored on a non-transitory computer-readable medium, said computer program product for controlling an internal combustion engine, the internal combustion engine comprising at least two cylinders, wherein each cylinder comprises at least one fuel injector configured to inject fuel into the cylinder, wherein said computer program product comprising computer instructions to cause one or more computer processors to perform the following operations:

• controlling the fuel injection performed by the fuel injectors into the cylinders based on an estimate of a residual gas imbalance between the at least two cylinders, wherein said controlling the fuel injection performed by the fuel injectors comprises:
• advancing a fuel injection timing of a fuel injector if the estimate of the residual gas imbalance between the at least two cylinders exceeds a threshold amount of residual gas in the cylinder comprising the fuel injector;
• and
• retarding the fuel injection timing of the fuel injector if the estimate of the residual gas imbalance between the at least two cylinders is less than a threshold amount of residual gas in the cylinder comprising the fuel injector.

A control arrangement for an internal combustion engine, the internal combustion engine comprising at least two cylinders, wherein each cylinder comprises at least one fuel injector configured to inject fuel into the cylinder, and wherein the control arrangement is configured to:

• control the fuel injection performed by the fuel injectors based on an estimate of an imbalance between residual gas in the at least two cylinders, wherein said control of the fuel injection performed by the fuel injectors comprises:
• advancing a fuel injection timing of a fuel injector if the estimate of the residual gas imbalance between the at least two cylinders exceeds a threshold amount of residual gas in the cylinder comprising the fuel injector;
• and
• retarding the fuel injection timing of the fuel injector if the estimate of the residual gas imbalance between the at least two cylinders is less than a threshold amount of residual gas in the cylinder comprising the fuel injector.
