ABSTRACT:
In an engine air-fuel ratio controller, a target frequency of an air-fuel ratio oscillation is set to a value different from a natural vibration frequency of a drive mechanism, and an air-fuel ratio feedback correction coefficient is set so that the air-fuel ratio oscillation frequency coincides with the target frequency, and the air-fuel ratio is rich for a longer time than the time for which it is lean. In this way, resonance of the air-fuel ratio oscillation frequency with the natural vibration frequency of the drive system is prevented, the air-fuel ratio is prevented from remaining lean in the high load region for a long period of time, and decline of driving performance is avoided.
