    • An air-fuel ratio imbalance among cylinders determining apparatus according to the present invention comprises an air-fuel ratio sensor having a protective cover and an air-fuel ratio detection element accommodated in the protective cover, and imbalance determining means. The imbalance determining means obtains a detected air-fuel ratio abyfs based on an output Vabyfs of the air-fuel ratio sensor every elapse of a constant sampling time ts, and obtains, as an indicating amount of air-fuel ratio change rate, a difference (detected air-fuel ratio change rate ΔAF) between a present detected air-fuel ratio abyfs which is newly detected and a previous air-fuel ratio abyfsold which was detected the sampling time ts ago, an average of the detected air-fuel ratio change rate ΔAF, and the like. The imbalance determining means determines that the air-fuel ratio imbalance among cylinders state is occurring, when a magnitude of the indicating amount of air-fuel ratio change rate is larger than an imbalance determination threshold.

    • When the ratio of the amount of vaporized fuel (purge amount) to be introduced into an intake passage of an engine from a fuel tank through a purge passage pipe, a purge control valve, etc. to the total amount of fuel (total fuel amount) to be supplied to the engine is large, an abnormality determination system acquires, as a parameter Pon, the air-fuel ratio imbalance index value that increases as the difference between the air-fuel ratios of the respective cylinders increases. When the purge amount is small relative to the total fuel amount, the determination system acquires the air-fuel ratio imbalance index value as a parameter Poff. When the difference between the parameters Pon and Poff is less than a predetermined value and at least one of these parameters is greater than a predetermined threshold value, the determination system determines that an inter-cylinder air intake amount variation abnormality is occurring.

    • An air-fuel ratio imbalance among cylinders determining apparatus (a determining apparatus) according to an aspect of the present invention, obtains a parameter X for imbalance determination which becomes larger as a variation of an air-fuel ratio of an exhaust gas passing through a position at which the air-fuel ratio sensor is disposed becomes larger, based on an output value Vabyfs of an air-fuel ratio sensor 67. At the same time, the determining apparatus changes a target air-fuel ratio which is a target value of an air-fuel ratio of a mixture supplied to an engine to “an air-fuel ratio (a target rich air-fuel ratio AFrich or a target lean air-fuel ratio AFlean) other than a stoichiometric air-fuel ratio” from the stoichiometric air-fuel ratio. Accordingly, the determining apparatus can obtain the parameter X for imbalance determination in a state in which a responsivity of the air-fuel ratio sensor 67 is not low. As a result, it can make a determination on the air-fuel ratio imbalance among cylinders with high accuracy.
