Internal combustion engine control apparatus
This patent describes an internal combustion engine control apparatus comprising: idling operation condition detection means for detecting an idling operation condition of an internal combustion engine in which the engine is idling; rotational speed detection means for detecting a rotational speed of the engine; comparing means for comparing the rotational speed detected by the rotational speed detection means with a predetermined target idle rotation value at a time when the idling operation condition detection means detects the idling operation condition; control means, responsive to a comparison result of the comparing means, for controlling an idling speed of the engine such that the detected rotational speed coincides with the predetermined target rotating value; operation parameter detection means for detecting an operation parameter indicative of amount of air intake into cylinders of the engine when the idling operation condition detection means detects the idling operation condition and the rotational speed detected by the rotational speed rotational speed detection means is lower than a preset rotational speed.
