Abstract
A device and a method for controlling an internal combustion engine, in particular a diesel internal combustion engine, having at least one solenoid valve, are described. On the basis of a desired quantity of fuel, an actuation period is determined for the solenoid valve and a signal for fixing the end of actuation is prescribed on the basis of the actuation period. Depending on the operating state of the internal combustion engine, the actuation period is determined either by means of a pump characteristic table or the desired quantity of fuel is used directly as the actuation period. Moreover, depending on the operating state of the internal combustion engine, either an uncorrected or a corrected signal is used for fixing the end of actuation.
