SUPERCHARGING PRESSURE CONTROL DEVICE OF AIRCRAFT INTERNAL COMBUSTION ENGINE

摘要

PURPOSE:To change the opening of a waste gate valve to the opening where the target supercharging pressure is immediately obtained when the throttle opening is changed. CONSTITUTION:A waste gate valve 26 is provided in a bypass passage 24 to detour an exhaust turbine 20 of an exhaust turbocharger 10, and the supercharging pressure is controlled by this waste gate valve 26. The opening of the waste gate valve corresponding to the stored target opening is correctively controlled so that the supercharging pressure may be the target supercharging pressure, and the target opening is updated by the opening of the waste gate valve 26 where the supercharging pressure becomes the target supercharging pressure. Updating of the target opening is prohibited when the difference between the engine speed and the target speed is larger than the predetermined value.
