Title:

内燃機関システムの制御装置

Document Type and Number:

Japanese Patent JP7444126

Kind Code:

B2

Abstract:

To provide a control device for an internal combustion engine capable of suppressing deterioration of fuel consumption efficiency with a guarantee of a front-rear differential pressure of a constant or higher EGR capable of re-circulating an EGR gas.SOLUTION: A control device 50 comprises: a target supercharge pressure control related amount calculation unit 51A for calculating a target supercharge pressure control related amount; an EGR maintenance control related amount calculation unit 51B for calculating an EGR maintenance control related amount; a supercharge pressure regulation device control unit 51C for controlling a supercharge pressure regulation device on the basis of, a final supercharge pressure control related amount based on the target supercharge pressure control related amount and the EGR maintenance control related amount; an EGR valve control unit 51D for controlling an EGR valve so as to be close to a target EGR rate; and a fuel ejection timing control unit 51E for controlling fuel ejection timing so as to perform ignition in target ignition timing. A suction/fuel corporation control unit 51F is provided for increasing an EGR gas amount and advancing the fuel ejection timing so as to perform the ignition at a position advanced from the target ignition timing in a case where an actual supercharge pressure is higher than a target supercharge pressure by a predetermined pressure or more.SELECTED DRAWING: Figure 1
