Abstract
In a method of injecting fuel into the combustion chambers of an internal combustion engine having a plurality of cylinders, wherein a main injection process and a variable number of secondary injection processes assigned to the main injection process are carried out during one working cycle of a piston, a change of the number of secondary injection processes is initiated initially only for some of the cylinders, while the original number of secondary injection processes is maintained for the other cylinders. Subsequently, the proportion of the cylinders to which the change of the number of secondary injection processes is applied is increased.
