摘要： Air-fuel ratio control of an internal combustion engine is performed using sensors for detecting operating conditions of the engine, such as the intake air amount, engine rotational speed, or air-fuel ratio; a fuel injection valve driven by an electrical signal to inject fuel; and a control circuit for receiving signals from the operating condition sensors, performing predetermined operations and generating an electrical signal for driving the fuel injection valve. The control circuit performs a step of calculating an air-fuel ratio variation D(A/F) with respect to an optimum air-fuel ratio based on the ratio of a change .DELTA.F, of an air-fuel ratio correction signal F during acceleration under air-fuel ratio feedback control based on a signal from the air-fuel ratio sensor, to an acceleration amount A, and a step of controlling a transient fuel correction ratio f(AEW) based on the obtained air-fuel ratio variation D(A/F).

摘要： In an internal combustion engine, a base fuel amount is calculated, and an air-fuel ratio deviation for each region is determined by a predetermined engine operating parameter when the engine is in a transient state such as an acceleration state or a deceleration state. A transient fuel correction amount is calculated in accordance with the calculated air-fuel ratio deviation for each region determined by the predetermined engine operating parameter. A fuel amount to be supplied to the engine is calculated by correcting said base fuel amount in accordance with the transient fuel correction amount.

摘要： A method for controlling the air-fuel ratio in an internal combustion engine in which the correction value of a transient fuel injection amount is decided, at a predetermined interval, in accordance with the acceleration or deceleration state of the engine, and the amount of fuel injection supplied to the engine is corrected by the decided correction value. In the process of the correction, the deviation of the air-fuel ratio from a reference air-fuel ratio in acceleration or deceleration of the engine is detected, and the correction value of the fuel injection amount correction in the transient state of the engine in accordance with the detected air-fuel ratio deviation is determined. In the correction of amount of fuel injection in the transient state of the engine, the correction value is decided on the basis of a factor for deciding the correction value and the blunted value of the factor for deciding the correction value.

摘要： A system for controlling the air-fuel ratio in an internal combustion engine provided with a fuel injector. The system has an O.sub.2 sensor for issuing signals on two levels, one corresponding to a high air-fuel ratio, the other to a low air-fuel ratio, and a feedback control device responsive to the signal from the sensor. The feedback control calculates a correction factor for maintaining the air-fuel ratio to a desired value during steady operation and for indicating the deviation in the ratio from the desired value during transient conditions. This deviation is employed to generate a transient correction value which is selected to minimize the deviation during transient conditions.
