    摘要: In an intake-air quantity control system of an engine employing a variable valve operating device capable of controlling a cylinder intake-air quantity by variable control of an operating characteristic of an intake valve, in a normal intake-valve operating mode a target operating characteristic of the intake valve is determined based on a target cylinder intake-air quantity calculated based on a target engine torque. In a predetermined high-load range, in particular, at full-load operation, the target operating characteristic is switched to a high-load period valve operating characteristic, preset to be suitable for the predetermined high-load range.

    摘要: An internal combustion engine control apparatus basically comprises a reference intake air quantity calculating section, a maximum intake air quantity calculating section and an engine control section. The reference intake air quantity calculating section is configured to calculate a reference intake air quantity corresponding to when an intake air is taken in as a sonic flow. The maximum intake air quantity calculating section is configured to calculate a theoretical maximum intake air quantity. The engine control section is configured to control the engine by using an intake air quantity function between a first value obtained by dividing the reference intake air quantity by the maximum intake air quantity and a second value obtained by dividing an actual intake air quantity corresponding to the valve characteristics of the intake valve by the maximum intake air quantity.

    摘要: At the time of obtaining a difference in intake air amount between right and left banks in a V-type engine, a target value of a lift-amount/operation-angle-varying mechanism provided for each of the banks is set to a target value at which flow velocity of intake air passing through an intake valve becomes almost sound velocity. In a state in which the flow velocity of intake air passing through the intake valve becomes almost sound velocity, a difference in the intake air amount in the right and left banks is detected and, to reduce the difference, a correction value for a target value of a valve lift is set for each of the banks.

    摘要: In an engine provided with a valve lift amount variable mechanism and a center phase variable mechanism for an intake valve, a region between a region where a flow rate of an intake air passing through the intake valve reaches a sonic speed and a region where an intake air amount does not substantially change relative to a change in an opening area of the intake valve is made to be a learning region. Then, in order to resolve an error in intake air amount in the learning region, a correction value for correcting control process of the valve lift amount variable mechanism is learned. When the learning of the correction value is converged, the learning correction value is corrected with an occupied rate of the valve lift amount variable mechanism in the influence ratio between influences on the two mechanisms in relation to the error. Further, based on the error occurring in a state corrected with the learning correction value which is corrected with the influence ratio, a correction value for correcting control process of the center phase variable mechanism is learned.
