ABSTRACT:
A method is described for regulating the fuel injection of an internal combustion engine, to which combustion air is fed through an intake tract, in which two final control elements which are connected in series in the intake tract and in each case control the air mass flow through the intake tract are controlled in respect of their position, an air mass flow (MF) into the intake tract and also an induction manifold pressure (P) prevailing in the intake tract between the final control elements are measured and measurement values are formed in the process, the actual position of both final control elements and the actual rotational speed of the internal combustion engine are sensed and model values for air mass flow (MF) and induction manifold pressure (P) are determined therefrom in an invertible numeric model and an alignment of the model is effected by means of the measurement values and model values, and desired positions for the two final control elements are ascertained from desired values for the air mass flow (MF) and the induction manifold pressure (P) by using a model inverted with respect to the aligned model, and the final control elements are set to the desired positions.
