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 (20), a bypass passage (24); flow amount adjustment means (25), operational state detection means (16), and driving time determination means (16). The. supercharger (20) is connected to an intake passage (6) of an internal combustion engine (1) and is driven by a motor (20a). The bypass passage (24) is provided for the intake passage (6) in such a manner as to bypass the supercharger (20). By being driven electrically, the flow amount adjustment means (25) can arbitrarily adjust a flow amount of air flowing through the bypass passage (24). The operational state detection means (16) detects an operational state of the internal combustion engine (1). The driving time determination means (16) determines a time at which the flow rate adjustment means (25) is driven based on a result of detection performed by the operational state detection means (16). <IMAGE>
