  "textContent": "A control apparatus for an internal combustion engine of the present invention switches a steady-state characteristic that defines a relation between an engine load factor and a throttle opening degree between a high atmospheric pressure steady-state characteristic and a low atmospheric pressure steady-state characteristic in accordance with whether or not the atmospheric pressure is higher than a predetermined value. According to the low atmospheric pressure steady-state characteristic, a throttle opening degree corresponding to an identical engine load factor is set to a smaller value compared to the high atmospheric pressure steady-state characteristic in a medium load region, and the throttle opening degree is set so as to increase as the engine load factor increases towards a full load in a region on the side of a higher load factor than the medium load region. When a request is not made to increase the intake air amount with a high response under a low atmospheric pressure, the control apparatus refers to the low atmospheric pressure steady-state characteristic and calculates a target throttle opening degree corresponding to a target engine load factor. In contrast, when a request is made to increase the intake air amount with a high response under a low atmospheric pressure, the control apparatus sets the target throttle opening degree so as to be a larger value than the target throttle opening degree calculated as described above.",
