PURPOSE:To improve drivability ever so high, by controlling supercharging pressure in keeping a waste gate valve in an exhaust bypass passage under control in time of normal driving, while relieving suction air in time of deceleration and thereby reducing pressure at the upstream side of a throttle valve without lowering the driving force of a supercharger. CONSTITUTION:In time of normal driving, on the basis of each detection signal out of sensor 18-20, a suction relief valve 12 installed in a suction relief passage 11 is closed by a control unit 17 via a solenoid valve 16 and an actuator 13, while a waste gate valve 7 installed in an exhaust bypass passage 6 is also closed. At this time, if supercharging pressure is more than the setting value, the valve 7 is opened by an actuator 8, making a part of exhaust gas escape to the passage 6, and driving force of a supercharger 4 is restrained. On the other hand, in time of deceleration, the relief valve 12 is opened, making a part of suction air out of a compressor 4b escape to the passage 11, and supercharging pressure lying between the compressor 4b and a throttle valve 5 is lowered down to the desired pressure for decelerating compensation.
