Abstract

In a method for operating an internal combustion engine, the fuel is supplied to at least one combustion chamber via at least one injector, which method includes the following steps: a) a total injection is divided into a basic injection and at least one measured injection; b) the injection time of the measured injection is successively decreased and the injection time of the basic injection is successively increased so that a total injection quantity ascertained from a valve characteristic curve remains the same.
