ABSTRACT:
A known control system for adjusting the lambda value of an internal combustion engine includes a corrective value ROM for transient operation wherein corrective values are stored for correcting the injection times for transient operation. In contrast thereto, the system according to the invention includes a corrective base value ROM 30, an adaptation value RAM 35 and an adaptation unit 34. The values from the corrective base value ROM are not utilized directly for correcting injection times; instead, these values serve as corrective base values which only become adapted corrective values by means of multiplication with adaptation values. The adaptation unit adapts the adaptation values in the adaptation value RAM. For this purpose, the adaptation unit determines the lambda value control deviations during a transient operation. If a control deviation is established, then the adaptation unit supplies a change value which is so dimensioned that an adaptation value, which is present for the monitored transient operation, is so corrected that for the next occurrence of a transient operation having the same initial operating conditions, only a smaller control deviation should occur and in the ideal case no such control deviation should occur. The control system according to the invention makes it possible to obtain very low toxic gas quantities also during a transient operation.
