A radiator assembly in a vehicle comprises a first coolant tank; a second coolant tank spaced apart from the first coolant tank; a plurality of moveable blades; a linkage coupled to the plurality of blades; and an actuator coupled to the linkage to adjust positions of the blades. Each of the plurality of blades has a first end pivotally coupled to the first coolant tank, a second end pivotally coupled to the second coolant tank and has a hollow body portion extending between the first end and the second end, and each of the blades is fluidly communicated with the first and second coolant tanks to form a coolant passage

In a heat exchange unit, a shutter device is disposed on a vehicle front side with respect to a coolant heat exchanger to open and close a passage for traveling air directed toward the coolant heat exchanger. A blower is switchable between a first blowing state in which air flows from the vehicle front side to the vehicle rear side and a second blowing state in which air flows from the vehicle rear side to the vehicle front side. In a case where a switch that makes a vehicle travelable is in an on state, a control unit switches the blower to the second blowing state, while an open degree of the shutter device is set at a closing side from a maximum open degree of the shutter device when a temperature of the engine coolant is equal to or lower than a predetermined temperature determination value.

A system for treating ambient air is provided. The system includes a flow control structure disposed on a vehicle. The flow control structure is adapted to control flow of ambient air received during movement of the vehicle. The system further includes an actuator operatively coupled to the flow control structure. The actuator is adapted to movably adjust the flow control structure. The system further includes a controller disposed on the vehicle and communicably coupled to the actuator. The controller is configured to control the actuator based on at least a quality of ambient air. The system further includes an air treatment component for selectively receiving ambient air from the flow control structure. The air treatment component is adapted to treat at least one pollutant present in ambient air.

A controller includes a forced-induction-device controlling section, an obtaining section that is configured to repeatedly obtain a temperature of the coolant in the intake-air cooling system, a determining section that is configured to determine whether the temperature obtained by the obtaining section is higher than or equal to a forced-induction limiting control starting temperature. On condition that the temperature of the coolant has risen to a value at which the determining section determines that the temperature obtained by the obtaining section is higher than or equal to the forced-induction limiting control starting temperature, the forced-induction-device controlling section starts a forced-induction limiting control to lower a forced-induction pressure. In the forced-induction limiting control, the forced-induction-device controlling section increases an extent of limiting of the forced induction as the temperature obtained by the obtaining section becomes closer to the boiling point.

A motor vehicle coolant heat exchanger having a modifiable covering system includes a support, a winding shaft mounted rotatably around a winding axis, a rotational drive, a roller-blind web, at least one pulling means winding body connected to the winding shaft to rotate together, and a pulling means. The roller-blind web is windable onto and unwindable from the winding shaft along a winding trajectory, which comprises a pulling crosspiece at its longitudinal end region located remotely from the winding shaft. The pulling means is unwindable from and windable onto the pulling means winding body parallel to the winding trajectory, which is connected at its longitudinal end remote from the pulling means winding body to the pulling crosspiece. The pulling means is guided around a deflection roller in such a way that its longitudinal end connected to the pulling crosspiece moves away from the winding shaft while it is being wound on.
