摘要： A catalyst is positioned in an exhaust path of an internal-combustion engine. A main air-fuel ratio sensor and sub-oxygen sensor are respectively positioned upstream and downstream of the catalyst. A main feedback operation is performed so that the output of the main air-fuel ratio sensor is fed back and reflected in the fuel injection quantity until the control A/F prevailing upstream of the catalyst coincides with the target A/F. A sub-feedback operation is performed so that the output of the sub-oxygen sensor is fed back and reflected in the fuel injection quantity until the air-fuel ratio of an exhaust gas flowing out of the catalyst agrees with a theoretical air-fuel ratio. Since a catalyst window varies in accordance with the intake air quantity, the fuel injection quantity is corrected so that the larger the intake air quantity becomes, the richer the control A/F is.

摘要： Internal combustion engine air-fuel ratio control apparatus and method in which the target air-fuel ratio of exhaust gas flowing into an exhaust-gas purification catalyst unit is controlled through at least proportional-integral control such that the correction amount per unit time of the oxygen amount in said catalyst unit is maintained constant. When the intake air amount is smaller than a predetermined amount and the air-fuel ratio detected by an oxygen sensor provided downstream of the catalyst unit is rich, the target air-fuel ratio is controlled to suppress an increase in the air-fuel ratio in the exhaust-gas purification catalyst unit. Accordingly, even if rapid acceleration operation is performed in a state where the intake air amount is extremely small and the air-fuel ratio detected by the oxygen sensor is rich, NOx in exhaust gas can be sufficiently removed through reduction reactions at the exhaust-gas purification catalyst unit.

摘要： An acceleration request is detected in accordance with an accelerator opening PA (time t3 in FIG. 5B). If the detected acceleration request is a moderate acceleration request, an idle opening TA0 is set as an actual throttle opening TA (FIG. 5E), and a request for retarding an intake valve timing VVT is issued (FIG. 5D). Recovery from fuel cut-off is achieved at time t4 at which a misfire limit value (combustion assurance VVT value L) is reached by an actual VVT value (FIG. 5A).
