Abstract:
A method of operating an internal combustion engine which has at least two separately controlled cylinder banks, an intake pipe leading to said cylinder banks, an air supply device for supplying combustion air to said intake pipe and said cylinder banks, said method comprising the steps of determining, as a function of a predetermined load (tl,desired) of the internal combustion engine, a desired pressure (ps,desired) in said intake pipe of the internal combustion engine as provided by means of said air supply device, determining for each cylinder bank at least one engine-related characteristic value consisting of at least one of ignition timing, beginning of fuel injection, duration of fuel injection, and opening and closing curves of the gas exchange valves, which affects the behavior of the internal combustion engine, comparing the characteristic values as determined for each cylinder bank and, in the event of a difference between the characteristic values of the cylinder banks, manipulating at least one engine operating parameter used to form of said characteristic values for at least one cylinder bank in such a way that the average of said at least one engine operating characteristic value equals a desired average value.
