Method of and apparatus for controlling supercharge pressure for a turbocharger |
摘要 |
Apparatus for controlling supercharge pressure for a turbocharger comprising means for determining any of operating zones to which a feedback control is applied, means for calculating a deviation between actual supercharge pressure and a target or preset supercharge pressure in accordance with the operating conditions of the engine, and means for selectively controlling capacity changing means and exhaust gas bypass valve means in accordance with the results of decisions and calculations, in which a control amount for the capacity changing means can be controlled in the direction of gradual increase in the capacity of the exhaust gas turbine or in the direction of decrease in the opening of the capacity changing means after the control is changed-over from the capacity changing means to the exhaust gas bypass valve means. Various data corresponding to the control steps for realizing the method are stored in a ROM of a microprocessor of an electronic control unit.
