    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： A difference is obtained between a cylinder pressure during the compression stroke when an exhaust gas recirculation control valve is opened, and a cylinder pressure during the compression stroke when the exhaust gas recirculation control valve is closed. An estimated value for this difference is set from a cylinder pressure detected under the closed conditions and an exhaust gas recirculation proportion. When the difference is smaller than the estimated value, it is assumed that the exhaust gas recirculation quantity is not changing in accordance with open/close control, and the occurrence of a fault in the exhaust gas recirculation unit is thus judged.

    摘要： A exhaust gas recirculation control value is forcibly open/close controlled at the time of steady operation. An estimation of whether or not the actual exhaust gas recirculation quantity has changed with open/close control of the exhaust gas recirculation control valve, is then made based on whether or not a change in combustion pressure accompanying the open/close is a value estimated for the operating conditions.
