Abstract
A method for determining at least one injection parameter of an internal combustion engine, including the following steps: detecting a pressure profile in a time-resolved manner in an injection system of an internal combustion engine at least during an injection; providing a reference pressure profile for at least one operating point of the injection system; comparing the detected pressure profile with the reference pressure profile, and ascertaining at least one injection parameter as a function of the comparison.
