Intake temperature control device for internal combustion engine

摘要

An intake temperature control device is provided for an internal combustion engine (10). An actuator (34) regulates a flow rate (Qf) of cooling fluid to adjust an amount of heat taken per unit time away from supercharged intake air in an inter cooler (18). The control device includes a flow rate setting device (60) and an operating device (60). The flow rate setting device (60) is for setting the flow rate (Qf) of cooling fluid at a larger value as an output of the engine (10) becomes higher, provided that a request to cool the intake air, which is supplied to the engine (10), is made. The operating device (60) is for operating the actuator (34) in order that an actual flow rate of cooling fluid reaches the flow rate (Qf) which is set by the flow rate setting device (60).
