Abstract
A method for controlling an injection of fuel in an internal combustion engine in which steady-state optimum injection parameters, in particular the start-of-injection angle, is corrected for non-steady-state operating phases. The correction is carried out by a transmission element to which the driver's request is fed as an input and correction parameters are determined therefrom. Using the correction parameters, fuel injection parameters obtained from a characteristic diagram that is optimum for steady-state operating conditions are corrected. In this manner, the behavior of the internal combustion engine is improved for non-steady-state operating phases.
