摘要：When it is detected that any one of a plurality of variable valve characteristic

mechanisms disposed for every cylinder groups is failed, an effective opening degree(valve lift amount, valve operating angle or the like) in a valve characteristic in the failedstate, is obtained. When the effective opening degree is judged to be a predeterminedvalue or above, the valve characteristic of the normal variable valve characteristicmechanism is controlled to be coincident with the valve characteristic in the failed state.When the effective opening degree is judged to be less than the predetermined value,there is performed a control for limiting the control to coincide the valve characteristic ofthe normal variable valve characteristic mechanism with the valve characteristic in thefailed state.
