An air intake duct is fixed to the lower surface of the rear floor panel of a vehicle. An oil cooler, which is an object to be cooled, is fixed to the lower surface of the air intake duct. An exhaust duct, which discharges air supplied to the oil cooler to the outside of the vehicle, is fixed to the lower surface of the oil cooler. The exhaust duct includes an exhaust port, which is open to the outside of the vehicle and is open downward from the vehicle. The intake duct includes an intake port, which is open to the outside of the vehicle and is opened at a position posterior to the rear tires of the vehicle, in other words, is opened in the rear wall portion of the rear bumper.

Vehicle duct structure

In a control devicefor a clutch unitfor transmitting rotation of a crankshaftof an engineto a water pumpfor circulating cooling water within the engine, it is determined that whether engagement or disengagement of the clutch unitwhen a request to start the engineis made, and the clutch unitis caused to be in an engagement state based on a determination result before cranking of the enginestarts.

Control device for internal combustion engine

A vehicle control systemincludes a water pumpwith an electromagnetic clutch, an oil relief device, an OCV, a water temperature sensor, and an ECU. The ECUcauses the electromagnetic clutch of the water pumpto be disengaged on the basis of the detection result detected by the water temperature sensor, and stops the coolant circulation. The ECUinstructs the OCVto adjust the lubricant pressure to low by an oil relief device. The ECUdetermines whether or not the adjustment of the lubricant pressure to low by the oil relief deviceis stopped on the basis of the detection result detected by the water temperature sensorwhen the engagement of the electromagnetic clutch of the water pumpcontinues for a given period.
