Abstract

A method for dynamic gas partial pressure correction of an internal combustion engine with external mixture formation. A mixture formation is carried out in an intake manifold upstream of the cylinder of the internal combustion engine, and in which in addition to the gas partial pressure of the fresh air flowing continuously into the intake manifold, the gas partial pressure of the fuel, fed discontinuously into the intake manifold, is also taken into account. The gas partial pressure of the fuel, fed into the intake manifold, said pressure which is assumed to be stationary as a function of determined parameters, is dynamically adjusted for each of the cylinder-individual, temporally successive injections, discharged into the intake manifold, by means of a correction factor and a fresh air correction filling value.
