摘要： Transmission shocks and idling defects such as engine racing and rough idling due to aging of a throttle opening area are prevented from occurring. An internal combustion engine control apparatus for controlling an internal combustion engine that has an air flow rate sensor for measuring a rate of air represented as an actual air rate, the air flowing into a cylinder, and a throttle valve for adjusting the rate of air, includes a throttle valve controlling section for controlling a throttle opening of the throttle valve to reach a preset throttle opening set depending on a target air rate for realizing a demand torque, and a throttle opening correcting section for correcting the preset throttle opening on the basis of the target air rate upon fuel cutoff that stops a fuel from being supplied to the internal combustion engine and of an actual air rate measured by the air flow rate sensor.

摘要： Provided is a fuel injection control device capable of accurately detecting a valve opening delay time of a fuel injection valve, and implementing high-precision minute injection control. A valve opening delay time of a fuel injection valve is estimated on the basis of a plurality of valve closing delay times obtained when the fuel injection valve is operated with injection pulse widths that are different injection pulse widths from each other and with which the fuel injection valve is in an intermediate lift state.
