Method of and apparatus for controlling supercharge pressure for a turbocharger

Patent ·
OSTI ID:5853942
;
This patent describes a method for controlling supercharge pressure of a turbocharger. The method comprises the steps of: detecting an acceleration condition of an engine based on an operating condition of the engine; performing a feedback control of the supercharge pressure by using a capacity changing means for changing the exhaust gas flow speed of the engine when the actual supercharge pressure has reached a first predetermined value after the acceleration condition is detected, the feedback control including correcting a control amount for operating the capacity changing means to control the supercharge pressure; and increasing a first target value of the supercharge pressure when predetermined time passes after the actual supercharge pressure reaches a second target value from the first predetermined value.
