Abstract
In a method for determining a filling difference between at least two cylinders of an internal combustion engine, e.g., an Otto-cycle engine, a power output parameter contribution made available by the respective cylinder to a total power output parameter of the internal combustion engine is ascertained for each of the at least two cylinders for different fuel quantities, and an air inhomogeneity between the at least two cylinders is ascertained on the basis of the power output parameter contributions, ascertained for the different fuel quantities, of the at least two cylinders.
