摘要： An internal combustion engine control apparatus can reliably detect abnormality in a crank angle position signal to ensure a fail safe function upon occurrence of the abnormally. A fuel injection signal and an ignition signal is generated based on the result of cylinder identification performed by a cylinder identification part and the crank angle position of the crank angle position signal. An abnormality determination part determines whether the crank angle position signal is abnormal. The cylinder identification part includes a cylinder identification resetting part for resetting the current content of the cylinder identification performed by the cylinder identification part upon determination of abnormality. The cylinder identification resetting part includes a fuel injection and ignition signal stopping part for stopping the fuel injection signal and the ignition signal, and a cylinder identification information clearing part for clearing previous cylinder identification information earlier than the last crank angle position signal upon determination of abnormality.

摘要： In throttle control, a throttle opening is set with sufficient control accuracy in accordance with the operating state of an engine despite variations in a throttle body and various kinds of sensors. A target effective opening area is calculated from a target amount of intake air, an atmospheric pressure, an intake pipe internal pressure and an intake air temperature by using a flow rate formula for a throttle type flow meter. A target throttle opening is calculated from a correlation map. An actual effective opening area is calculated from the amount of intake air, the atmospheric pressure, the intake pipe internal pressure, and the intake air temperature by using the above-mentioned flow rate formula, and a learning throttle opening is calculated from the correlation map. The target throttle opening is corrected by a throttle opening learning value calculated from a deviation between the target throttle opening and the learning throttle opening.

摘要： A control apparatus for an internal combustion engine prevents variation of an air fuel ratio even upon introduction of purge air. A delay time occurring until the intake air detected, after having arrived at the combustion chamber through a surge tank, influences an air fuel ratio sensor, a delay time occurring until purge air containing evaporated fuel generated upon purging a canister, after having arrived at the combustion chamber through the surge tank, influences the air fuel ratio sensor, and a delay time occurring until fuel supplied by an injector, after having arrived at the combustion chamber, influences the air fuel ratio sensor, are represented by simplified physical models. A purge rate in the combustion chamber or in the neighborhood of the air fuel ratio sensor is calculated by using the physical models, and a purge air concentration and a fuel correction amount are calculated based on the purge rate thus obtained.
