ABSTRACT:
An arrangement for the identification of the mass air stream supplied to the cylinders of an internal combustion engine. A controlled unit serves the purpose of controlling a prescribed relationship between mass air stream and fuel quantity, whereby a correction quantity (.tau.) from a performance characteristics memory is deposited dependent on at least one operating parameter. In accordance with the invention, this thereby involves a correction quantity which takes the dynamic behavior of the intake system, particularly its storage capacity, into consideration. Accordingly, the control unit identifies a corrected mass air stream which is smaller or, respectively, greater than the measured mass air stream by the sub-stream filling the storage or, respectively, flowing off from the storage.
