Abstract

A method and a device is described for controlling an internal combustion engine using fuel metering. The fuel metering is divisible into at least a first partial injection and a second partial injection. In the second partial injection, a fuel quantity variable, characterizing the fuel quantity injected in the second partial injection, is corrected on the basis of at least one pressure variable, characterizing the fuel pressure, as well as of the fuel quantity variable and at least one further variable.
