ABSTRACT:
A control apparatus for an internal combustion engine is arranged such that, for each of the operating condition sections (A, B, C) of an internal combustion engine (1), a deviation (K.sub.l) of a feedback control value in the section from a reference value is detected and written in a region in a memory corresponding to the section in the form of a map, and the deviation (K.sub.l) is read out such as to be used as a correction value when control is effected in relation to the corresponding operating condition section. In such control apparatus, whether or not the number of regions in the memory into which deviation values for operating condition sections (T.sub.p, N) have already been written has reached a predetermined value is examined. When the number has reached the predetermined value, a deviation value is written into each of the regions in the memory into which no deviation values have yet been written, this deviation value already being stored in the adjacent region in the memory in which writing of deviation data has already been completed, whereby the feedback control delay can be eliminated.
