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.
Claims11
A method for determining a fuel mass of a pre-injection that has been injected into at least one combustion chamber of a combustion engine with at least one injection under high pressure, the method comprising:
- measuring an actual amount of injected fuel of at least one test post-injection, the at least one test post-injection implemented based on a measure of a default nominal amount of a desired pre-injection;
- comparing the measure for the actual amount and a measure for a nominal amount of the at least one test post-injection;
- and
- determining a corrective variable for the pre-injection based on the step of comparing.
