The baffle system includes a bracket coupled directly to one of the first frame or the second frame, a baffle coupled to the bracket and positioned to facilitate selectively restricting airflow through at least a portion of at least one of the first cooler or the second cooler, and an actuator positioned to facilitate reconfiguring the baffle between a non-restrictive orientation and a restrictive orientation.

A cooling apparatus for a vehicle includes air-cooling first and second heat exchangers that are placed beside each other. A coolant flow-out portion of the first heat exchanger from which a first coolant which is a cooling target of the first heat exchanger flows out and a coolant flow-out portion of the second heat exchanger from which a second coolant which is a cooling target of the second heat exchanger flows out are placed at ends at opposite positions separated along a diagonal line on a parallel placement surface of the two heat exchangers. A first cooling fan is placed opposing the coolant flow-out portion of the first heat exchanger, and a second cooling fan is placed opposing the coolant flow-out portion of the second heat exchanger. With this configuration, cooling performance of two air-cooling heat exchangers placed beside each other can be improved.

A method for operating a vehicle cooling system includes generating via a main cooling unit a main cooling air flow passing through a first heat exchanger arrangement being associated with a main cooling path, generating via a secondary cooling unit, located upstream in the main cooling path, a secondary cooling air flow passing through a second heat exchanger arrangement being associated with a secondary cooling path branching off upstream in the main cooling path, in a first operating mode, operating via a control unit both the main cooling unit and the secondary cooling unit in order to generate mutually independent cooling air flows, and in a second operating mode, operating via the control unit the main cooling unit and setting the secondary cooling unit to one of a stationary or an idle operating state.

An internal combustion engine includes an intake air temperature adjustment apparatus that adjusts the temperature of intake air, and a control apparatus that operates at least the intake air temperature adjustment apparatus. When the internal combustion engine operates in a stoichiometric EGR mode, the control apparatus operates the intake air temperature adjustment apparatus so that the temperature of intake air entering a combustion chamber enters a first temperature region. When the internal combustion engine operates in a lean mode, the control apparatus operates the intake air temperature adjustment apparatus so that the temperature of intake air entering a combustion chamber enters a second temperature region that is a lower temperature region than the first temperature region.
