Abstract
A method for correcting the injection duration of injections is based on pressure fluctuations of preceding injections. The injection duration is determined on the basis of a mapping value and of a correction value. The mapping value is read out from a mapping according to the fuel pressure and according to the amount of fuel to be injected. The correction value is calculated according to the time interval between the subsequent injection and at least one latter injection. This enables a precise determination of the injection duration and thus a precise metering of the desired amount of fuel.
