ABSTRACT:
An air-fuel ratio controller, including: fuel injection apparatus to supply an engine with fuel, a quantity of fuel to be delivered by the fuel injection apparatus being controlled by an impressed fuel quantity injection pulse having an injection time width corresponding to a desired fuel quantity; engine status detecting apparatus for detecting a status of at least one of a rotation frequency, intake manifold pressure, and volumetric efficiency operating parameter with respect to an operation of the engine; basic fuel quantity calculating apparatus for calculating a basic fuel quantity according to the status detected by the engine status detecting apparatus; air-fuel ratio sensor apparatus for detecting an air-fuel ratio in an exhaust gas from the engine; proportional integral processing apparatus for integrally processing and calculating an actual fuel quantity according to the output from the air-fuel ratio sensor apparatus; learning apparatus for calculating, using an output from the integral processing apparatus, a learned value to correct the basic fuel quantity into a controlled fuel quantity; learned value correcting apparatus for correcting the basic fuel quantity by using the learned value from the learning apparatus; and, calculation prohibiting apparatus for prohibiting the learning apparatus from calculating until a predetermined time lapses after the engine starts, or until a predetermined time lapses after an engine cooling water temperature is detected to have reached a predetermined temperature level.
