    Abstract: A preparation control for suppressing fluctuation of an output torque of the engine at the time of executing switching operation from the whole cylinder operation to the partial cylinder operation is executed when having made a switching request from the whole cylinder operation to the partial cylinder operation. The target switching time executing the switching operation is calculated in accordance with the valve operation phase after the preparation time is completed. The cylinder deactivation mechanism is controlled such that the switching operation is executed at the target switching time. The target switching time is set in accordance with the valve operation phase at the timing in which the abnormal noises are not generated.

    Abstract: A control system for an internal combustion engine having a throttle valve disposed in an intake passage of the engine. A target intake air amount of the engine is calculated, and an intake pressure of the engine is estimated. A wide-open intake air amount is calculated according to the engine rotational speed, and a theoretical intake air amount is calculated according to the wide-open intake air amount and the intake pressure. The wide-open intake air amount is an intake air amount corresponding to a state where the throttle valve is fully opened, and the theoretical intake air amount is an intake air amount corresponding to a state where no exhaust gas of the engine is recirculated to a combustion chamber of the engine. further, an exhaust gas recirculation ratio is calculated using the theoretical intake air amount and the target intake air amount, and a target output torque of the engine is calculated using the target intake air amount and the exhaust gas recirculation ratio. The engine is controlled using the target output torque.

    Abstract: An intake control system for an internal combustion engine is capable of ensuring a differential pressure across an EGR valve, and controlling an EGR amount with high accuracy. A target fresh air amount is set based on a demanded torque calculated according to operating conditions of the engine. A differential pressure across an EGR valve is set as a target differential pressure. When it is determined that the across-valve differential pressure is not in a state in which the target differential pressure can be ensured, an opening degree of the EGR valve is controlled to limit an EGR amount. An opening degree of a throttle valve is controlled based on the target fresh air amount, so as to ensure the target differential pressure.

    Abstract: A preparation control for suppressing fluctuation of an output torque of the engine at the time of executing switching operation from the whole cylinder operation to the partial cylinder operation is executed when having made a switching request from the whole cylinder operation to the partial cylinder operation. The target switching time executing the switching operation is calculated in accordance with the valve operation phase after the preparation time is completed. The cylinder deactivation mechanism is controlled such that the switching operation is executed at the target switching time. The target switching time is set in accordance with the valve operation phase at the timing in which the abnormal noises are not generated.

    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.
