Abstract
In an adaptation method of an internal combustion engine for optimized combustion, the actually supplied cylinder-specific air masses are determined by determining the change in speed of the internal combustion engine within a thrust phase and by assigning these changes in speed to the cylinder-specific compression phases. This enables the fuel quantity to be injected to be more precisely adjusted to the cylinder-specific air mass available.
