Title:
内燃機関の過給圧制御装置
Document Type and Number:
Japanese Patent JP7054716
Kind Code:
B2
Abstract:
The disclosure provides a supercharging pressure control device for an internal combustion engine that may suppress misfires of the internal combustion engine caused by a large amount of condensed water and freezing of an intercooler and suppress the decrease in supercharging response under the conditions that such problems are unlikely to occur. The supercharging pressure control device for the internal combustion engine includes a supercharger (turbocharger), an intercooler, a supercharging pressure control part controlling a supercharging pressure based on a target supercharging pressure, and an intake air temperature acquisition part (intake air temperature sensor) acquiring a temperature of the intake air as an intake air temperature, and executes a supercharging pressure reduction control when the intake air temperature is greater than or equal to a specified first threshold temperature or less than or equal to a specified second threshold temperature less than the first threshold temperature.
