    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 failed state, is obtained. When the effective opening degree is judged to be a predetermined value or above, the valve characteristic of the normal variable valve characteristic mechanism 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 of the normal variable valve characteristic mechanism with the valve characteristic in the failed state.

    摘要： The heat generating ratio for every crank angle is calculated as a combustion ratio for the total amount of heat generated by the engine, and the ignition timing is so corrected that the crank angle corresponding to from 10% to 90% of the combustion ratio becomes minimal or is so corrected that the combustion ratio at a predetermined crank angle becomes equal to or larger than a predetermined value. This makes it possible to so control the ignition timing that the engine produces a maximum torque.

    摘要： In an internal combustion engine provided with a variable valve mechanism that variably controls at least an operating characteristic (valve lift amount and the like) of an intake valve, a valve opening area AWm at a valve overlap time is calculated based on a valve lift amount (VCS-ANGL) and opening timing IVO of the intake valve, and a spit-back gas amount Wm at the valve overlap time is calculated based on the valve opening area AWm. On the other hand, a volume flow ratio (basic actual engine volume flow ratio) RQH0VEL1 in the intake valve, equivalent to an actual intake air amount of the engine, is calculated based on the valve lift amount and closing timing of the intake valve, and a basic residual gas amount Wcyl is calculated based on the basic actual engine volume flow ratio RQH0VEL1. Then, a resultant obtained by adding the spit-back gas amount Wm and the basic residual gas amount Wcyl, is set as a total residual gas amount of the engine. Further, in the case where an intake air amount control is performed by the variable valve mechanism, a target valve operating characteristic is set based on a target intake air amount which is set according to an operating condition of the engine, and the variable valve mechanism is controlled so that the valve operating characteristic of the intake valve reaches the target valve operating characteristic. At the moment, by executing a residual gas based correction to set the target valve operating characteristic, a high accurate intake air amount control is realized.
