摘要: In a method for operating an internal combustion engine, a first data quantity is derived based on a signal of a first sensor which detects the pressure in a first combustion chamber of a plurality of combustion chambers, and a second data quantity is derived based on a signal of a second sensor, which second data quantity is a function of the pressure variation in at least one of the plurality of combustion chambers. The first data quantity and the second data quantity are functions of the pressure variation in the same combustion chamber, and a drift of the second sensor is ascertained from a change over time in the second data quantity with respect to the first data quantity.

摘要: A device and a method for controlling an internal combustion engine are provided, in which a first actuating variable of at least one first actuating element is adapted on the basis of a comparison between a first cylinder-specific variable characterizing the combustion process in at least one cylinder and a setpoint value for this variable. On the basis of at least one second variable, at least one deviation value for at least one additional cylinder is determined. Based on this deviation value, a second actuating variable of a second actuating element is adapted.
