Abstract: An air-fuel ratio control device includes an air-fuel ratio sensor provided upstream from a three-way catalyst, and an oxygen sensor provided downstream from the three-way catalyst. The air-fuel ratio control device controls the fuel supply amount based on the output from the air-fuel ratio sensor, and compensates for errors in the air-fuel ratio sensor by correcting the fuel supply amount based on the output from the oxygen sensor. The fuel supply correction amount is calculated based on an integral term that integrates the deviation between the output from the downstream air-fuel ratio sensor and the target air-fuel ratio. When a fuel supply adjustment control is executed, the value of the integral term in the sub-feedback control is not updated for a predetermined period after the fuel supply adjustment control ends. The actual air-fuel ratio is thus brought to the target air-fuel ratio in an appropriate manner.

Abstract: An engine ECU calculates a rotational variation based on a required rotation time when a complete misfire occurs in a cylinder, a required rotation time when complete combustion occurs in the cylinder, and a required rotation time during the current combustion stroke, and integrates the calculated rotational variation.

If the amount of learning value deviation is equal to or greater than a certain amount, the engine ECU corrects a learning value of a sub-feedback control with respect to the air-fuel ratio.

Abstract: A control device for a spark-ignition internal combustion engine that sets ignition timing based on a target value of a predetermined combustion-related parameter correlated with a combustion state and operates an ignition device in accordance with the ignition timing thus set. The control device calculates an actual value of the combustion-related parameter from an output value of the cylinder pressure sensor and feeds back the calculated value of the combustion-related parameter to the setting of ignition timing. Further, in parallel with the above processing, the control device calculates a value of a predetermined combustion variation parameter correlated with the magnitude of combustion variation from the output value of the cylinder pressure sensor. If the calculated value of the combustion variation parameter deviates from an allowable range of the combustion variation, the control device stops the feedback of the calculated value of the combustion-related parameter.

Abstract: The present invention relates to an air-fuel ratio control device for an internal combustion engine, and makes it possible to maintain high purification performance by suppressing a decrease in the oxygen occlusion capability of a catalyst. When an O2 sensor output oxs is greater than a reference value oxsref, which corresponds to a stoichiometric air-fuel ratio, and smaller than an upper threshold value oxsrefR, a sub-FB reflection coefficient is fixed at a predetermined value vdox2 for providing a lean air-fuel ratio. When, on the other hand, the O2 sensor output oxs is smaller than the reference value oxsref and greater than a lower threshold value oxsrefL, the sub-FB reflection coefficient is fixed at a predetermined value vdox2 for providing a rich air-fuel ratio. The sub-FB reflection coefficient reflects the O2 sensor output oxs in the calculation of a fuel injection amount and increases or decreases to have a consequence on the air-fuel ratio of an exhaust gas.
