SUPERCHARGING PRESSURE CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

Abstract:

A supercharging control device of an internal combustion engine includes: a supercharger, disposed in the internal combustion engine, and configured to increase a supercharging pressure by changing a variable nozzle opening degree to a closed side; a supercharging pressure obtaining part, obtaining the supercharging pressure; a limit value setting part, setting a limit value which setting the opening degree of the closed side of the variable nozzle based on a pressure of a side of a turbine of the supercharger; and an opening degree setting part, setting the opening degree of the variable nozzle to the limit value when the supercharging pressure is increased toward a target supercharging pressure, and then gradually setting to an open side.
