A control device of an internal-combustion engine

Japanese Patent JP6232890

B2

PROBLEM TO BE SOLVED: To suppress a rise of an outlet-side intake air temperature of a mechanical supercharger accompanied by the close fastening of a bypass valve.SOLUTION: A control device 16 of an internal combustion engine comprises: a mechanical supercharger 8 which is arranged in an intake passage 2, and driven by being constantly transmitted with an output of the internal combustion engine 1; a bypass passage 9 which makes an upstream side and a downstream side of the mechanical supercharger 8 of the intake passage 2 communicate with each other; a bypass valve 10 which opens and closes the bypass passage 9; and a throttle valve 12 which is arranged at a downstream side rather than a merging part between the intake passage 2 and the bypass passage 9. Then, the control device 16 comprises close fastening detection means 16 which detects the close fastening of the bypass valve 10, and when detecting the close fastening of the bypass valve 10, sets a target opening of the throttle valve 12 to an opening larger than a prescribed opening, and performs fuel cut control for controlling fuel injection.
