Abstract
The control device of an internal combustion engine of the present invention is a control device of an internal combustion engine in which a bypass channel () for bypassing a throttle valve () of an engine intake system () via an evaporated fuel adsorption device is provided as a fuel emission path to an evaporated fuel adsorption device () for adsorbing evaporated fuel in a fuel tank (), and exhaust gas recirculation is implemented for recirculating exhaust gas via an exhaust gas recirculation passage () connected upstream of the entrance of the bypass channel of the engine intake system. An exhaust control valve () is disposed in the exhaust gas recirculation passage, intake control valves () are disposed in the bypass channel, and when the opening degree of the exhaust control valve is greater than a set opening degree, either the intake control valve is fully closed or the opening degree of the intake control valve is reduced in comparison with times when the opening degree of the exhaust control valve is equal to or less than the set opening degree.
