Abstract (en)
[origin: WO2022106188A1] The invention relates to a method for operating an internal combustion engine (1) in a powered operation, in which the internal combustion engine (1) has an intake valve device (10) and a sudden load variation is carried out in which a torque provided by the internal combustion engine (1) is increased from a first value to a second value which is higher than the first value. While the sudden load variation is being carried out, the intake valve device (10) is operated according to an operating method different from the Miller method and is thereby closed later than in the Miller method. After the sudden load variation has been carried out, and while the internal combustion engine (1), via its output shaft, provides the torque having the second value after the sudden load variation has been carried out, the internal combustion engine (1) is switched over from the operating method different from the Miller method to the Miller method, and as a result the intake valve device (10) is operated according to the Miller method and is thereby closed earlier than in the operating method.
