  • Patent number: 4594985
    Abstract: In the learning control apparatus and method for air/fuel ratio of an internal combustion engine operated with fuel injection of the type that the actual fuel injection time duration is modified according to the mean value of each two successive end values of the air/fuel ratio feedback complementing factor in the constantly increasing and constantly decreasing modes, the actual fuel injection time duration is further modified to be stepwise increased when the air/fuel ratio feedback complementing factor increases above a predetermined value during lean side operation of the engine, or to be stepwise decreased when the air/fuel ratio feedback complementing factor decreases below a predetermined value during rich side operation of the engine.
