Control apparatus and control method for internal combustion engine

摘要

A control apparatus for an internal combustion engine in accordance with the invention includes a supercharger, a bypass passage, a flow amount adjustment device, an operational state detection portion, and a driving time determination portion. The supercharger is connected to an intake passage of an internal combustion engine and is driven by a motor. The bypass passage is provided for the intake passage in such a manner as to bypass the supercharger. By being driven electrically, the flow amount adjustment device can arbitrarily adjust a flow amount of air flowing through the bypass passage. The operational state detection portion detects an operational state of the internal combustion engine. The driving time determination portion determines a time at which the flow rate adjustment device is driven based on a result of detection performed by the operational state detection portion.
