    摘要： A system and method of optimally controlling ignition timings in an engine conditioned in first and second modes of intake control. A control unit includes an unthrottled operation control conducting the first mode by varying a closing timing of an intake valve and fixing a throttle position of a throttle valve, a throttled operation control conducting the second mode by varying the throttle position of the throttle valve and fixing the closing timing of the intake valve, and an ignition timing control determining different ignition timings to be used in the first and second modes.

    摘要： In control apparatus and method for an internal combustion engine having variably operated engine valves, a target vacuum pressure is calculated on the basis of an engine driving condition and an opening angle of an electronically controlled throttle valve is disposed in an intake air passage to achieve the target vacuum pressure. A target air quantity to be sucked within an engine cylinder on the basis of the engine driving condition is calculated and a valve closure timing of an intake valve of, e.g., an electromagnetic operation type is controlled to achieve the target air quantity. At this time, in accordance with the target vacuum pressure TBOOST(or in accordance with an actual vacuum pressure BOOST detected by means of a vacuum pressure sensor), the target air quantity to calculate the valve closure timing of the intake valve calculated on the basis of target air quantity is corrected or the intake valve closure timing IVC per se is corrected by a correction value of &Dgr;IVC.
