CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of suppressing the deterioration of exhaust emission and drivability by improving control responsivity when EGR amount is increased.SOLUTION: A control device for an internal combustion engine includes: a throttle valve 16 disposed in an intake passage 10; an EGR passage 40 for connecting an exhaust passage 20 and the intake passage 10 on an upstream side of the throttle valve 16; an EGR valve 44 disposed on the EGR passage 40; an air bypass passage 36 for connecting an upstream side of a connecting portion with the EGR passage 40 in the intake passage 10 and a down stream side of the throttle valve 16; and an air bypass valve 38 for opening/closing the air bypass passage 36. The throttle valve 16 and the EGR valve 44 are respectively operated to be target openings calculated on the basis of the opening of the air bypass valve 38, a target EGR rate, and target air amount. The air bypass valve 38 receives a predetermined acceleration request to switch its opening from an open valve to a close valve.
