    摘要： A control device for an engine provided with a turbocharger properly uses a parameter used for controlling a center-of-gravity position of a heat generation rate determined by a heat generation rate as the amount per unit crank angle of heat generated by combustion of fuel depending on operating situations of the engine and a vehicle in which the engine is mounted. Specifically, an increase in a turbocharging pressure of the turbocharger is executed when a rotational speed of the engine and a speed of the vehicle in which the engine is mounted are lower than predetermined reference values in a case where the center-of-gravity position of a heat generation rate is further on a retard side than a predetermined crank angle and one or both of an increase in a fuel injection pressure and advancing of a fuel injection timing are executed when the rotational speed of the engine or the speed of the vehicle in which the engine is mounted are equal to or higher than the predetermined reference values in the case where the center-of-gravity position of a heat generation rate is further on the retard side than the predetermined crank angle. Then, fuel economy can be improved by the center-of-gravity position of a heat generation rate being maintained at a predetermined fixed value regardless of a load of the engine and/or the engine rotational speed while an increase in noise and vibration a user feels uncomfortable with is suppressed.

    摘要： To provide a control device capable of setting a plurality of combustion parameters changing a combustion state of an internal combustion engine to appropriate values and improving a fuel consumption rate regardless of an operation state. An engine ECU 70 sets a combustion parameter (main injection timing, pilot injection timing, fuel injection pressure, turbocharging pressure, or the like) such that a center-of-gravity position of a heat generation rate becomes a constant target crank angle regardless of a load of an engine 10, In addition, the ECU 70 estimates the center-of-gravity position of a heat generation rate based on an output of an in-cylinder pressure sensor 64 and feedback-controls the combustion parameter such that the estimated center-of-gravity position of a heat generation rate becomes equal to the target crank angle.

    摘要： A control device includes: a first phase changing portion retarding a first intake valve phase relative to a second intake valve phase; a throttle valve adjusting an intake air amount of the engine, and a control portion configured to perform an intake valve phase control which controls the first phase changing portion to retard the first intake valve phase relative to the second intake valve phase such that an air amount in the cylinder of the engine is reduced to a target value to perform rich combustion, and the control portion configured to perform a throttle valve closing control which controls the throttle valve such that the air amount in the cylinder is the target value or smaller after the air amount in the cylinder is not reduced to the target value or smaller by the intake valve phase control performed by the first phase changing portion.
