Abstract

PURPOSE:To increase an output torque and miniaturize the device of the system by a method wherein a set supercharge pressure, determined by an acceleration requesting signal and the revolving speed of an engine, is compared with the actual supercharging pressure in a suction duct while the control of the supercharging pressure is effected by a signal based on the comparation. CONSTITUTION:When P1>P2 (P1: set pressure signal, P2: the pressure signal in accordance with the actual supercharging pressure in the suction duct 14), a signal to close a valve 6 is supplied from a comparator 11 to an actuator 13, the actuator 13 closes the valve 6 in a flow path 7 and the supercharging pressure in the suction duct 14 is increased. When P1<P2, the signal to open the valve 6 is suppplied from the comparator 11 to the actuator 13, the valve 6 is opened by the actuator 13 and the actual supercharging pressure in the suction duct 14 is decreased. When P1=P2, the actuator 13 keeps the opening degree of the valve 6.
