ABSTRACT:
A method of and an apparatus for controlling supercharge pressure in which a preset supercharge pressure is increased when an acceleration condition is determined or detected and the actual supercharge pressure can be feedback-controlled to a new target supercharge pressure in the acceleration condition through an electromagnetic valve and an actuator by a control signal from an electronic control unit including a microprocessor, in accordance with the detected parameters such as supercharge pressure, intake air flow rate. Any control errors brought about by variations in parts, such as diaphragm variations and variations during assembly of the exhaust bypass valve, as well as changes in engine performance with time, can be eliminated.
