Beschreibung
Zusammenfassung:	A fuel injection time is calculated from a flow rate of intake air to an internal combustion engine. A rotational speed of the engine is sensed. A desired recirculation rate of exhaust gas is determined by a central processing unit from the fuel injection time and the rotational speed of the engine using memory which contains a two-dimensional look-up table, each lattice point in the table being defined by axes of fuel injection time and rotational speed of the engine, and each lattice-point containing the value of a desired recirculation rate of exhaust gas.
