Abstract

A method for the determination of a fuel mass of a pre-injection injected into at least one combustion chamber of an internal combustion engine by means of at least one injection under high pressure is characterized in that a corrective variable is determined for the pre-injection by means of a comparison between a measure for the actual amount of injected fuel of at least one test post-injection carried out for a predetermined target amount of a desired pre-injection due to a measure, and the measure for the target amount.
