Abstract:
1. A method for controlling fuel injection by means of injectors in a multicylinder internal combustion engine, with the method comprising the steps of: activating the injectors sequentially in accordance with activation data for opening and closing in injection processes, with a specific injection segment in which injections are possible being provided for each cylinder in an operating cycle, executing a number of injection processes for the cylinder per injection segment, predetermining duration and temporal position in the injection segment for these injection processes, grouping injection processes for each cylinder into a number of packets of which the respective injection processes are executed directly after each other, and processing the packets during fuel injection in a sequence in which packets of different cylinders follow directly after each other, wherein a) In a distribution step the injection processes are distributed to the packets without taking into account an undesired simultaneity of the packets of different injection segments or cylinders, and b) In a collision correction step a modification or suppression of at least partly overlapping and thereby colliding injection processes is performed such that the condition will be averted.
