Abstract

An internal combustion engine control apparatus in which upon detection of transient state of the engine such as acceleration, deceleration or the like, the amount of fuel supply to the engine is corrected by using transient correcting coefficients which are determined previously and updated through learning procedure. The correcting coefficient is updated on the basis of the result of comparison of the air-fuel ratio detected upon occurrance of the transient state with a predetermined reference value.
