A method for operating an internal combustion engine. The method includes detecting a structure borne sound signal in a time-dependent manner for the at least one combustion chamber during operation of the internal combustion engine, and determining, in a predetermined measuring window, at least one evaluation parameter from the detected structure borne sound signal. The method also includes obtaining at least one comparative result by comparing the at least one evaluation parameter with at least one predetermined comparison value, and assigning to the structure borne sound signal, on the basis of the at least one comparative result, one of a knocking event in the at least one combustion chamber and an interference signal.

Method for operating an internal combustion engine having at least one combustion chamber and internal combustion engine for carrying out such a method

A method for operating an internal combustion engine, in particular a gas engine, having two cylinder banks, each of which includes multiple cylinders, wherein each cylinder bank is independently supplied with charging pressure, and having a device for actively deactivating at least one cylinder of each cylinder bank. When the operating state is switched from a state with at least one deactivated cylinder to an operating state with at least one other activated cylinder, the charging pressure is reduced prior to the activation of the other cylinder.
