1. A method of determining a vibration-optimized adjustment of an injection device of an internal combustion engine, the method comprising the step of:

  • providing for a specific engine adjustment by the injection device for each cycle of the internal combustion engine a plurality of at least two individual injections per cylinder, each of which is defined at least by a relative injection instant and an individual injection quantity,wherein a time characteristic of a resulting pressure that is influenced by pressure waves caused by the individual injections is determined in a fuel-carrying part of the injection device, wherein said adjustment is determined by varying the injection instant of at least one of;

    at least one individual injection and an individual injection quantity of at least one individual injection in such a way that this adjustment is characterized by a reduced temporal fluctuation of the resulting pressure as a result of at least partially destructive interferences between said pressure waves.
