Abstract: An internal combustion engine control apparatus including a rotational speed sensor detecting a rotational speed of an internal combustion engine, an intake air amount sensor detecting an amount of an intake air supplied into a combustion chamber, a command detector detecting a command of a deceleration of a vehicle on which the internal combustion engine is mounted or a torque down of the internal combustion engine, and a microprocessor. The microprocessor is configured to perform: determining whether a retard condition of an ignition timing is satisfied based on a value detected by the rotational speed sensor or the intake air amount sensor when the command is detected by the command detector, and controlling an ignition part so as to perform an ignition-timing retard control to delay the ignition timing of the ignition part when it is determined that the retard condition is satisfied.

Abstract: A control device of an internal combustion engine is provided. In the case where a switch request for switching from all-cylinder operation to partial-cylinder operation is made, before a switch from the all-cylinder operation to the partial-cylinder operation is executed, an intake air amount increase control increasing an intake air flow rate of an engine by increasing an opening degree of a throttle valve is performed, an ignition timing retardation control retarding an ignition timing is performed, and based on a retardation limit value of the ignition timing at a time point when the switch request is made, a start timing of the intake air amount increase control is changed. As a retardable amount being a difference between an initial ignition timing and the retardation limit value decreases, the start timing of the intake air amount increase control is delayed further.
