A heat exchanger system for an agricultural vehicle. The heat exchanger system has at least two separate heat exchanger assemblies, where an adjustable baffle is used to vary the airflow between the heat exchanger assemblies, accordingly varying the cooling effect of the assemblies, based on system requirements. The adjustable baffle may be arranged to restrict or block at least a portion of a heat exchanger to reduce airflow through the exchanger, to provide a flow bypass of an exchanger, and/or to proportionally adjust the airflow through a pair of heat exchangers provided as part of a single heat exchanger assembly.

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.

The invention relates to a heat exchange module (402) for a motor vehicle, comprising: a first heat exchanger (404) comprising at least a first stage (404a) and a second stage (404b), said first heat exchanger being configured such that the first and the second stages are in fluid connection within the same cooling circuit (600) of the motor vehicle; a ventilation device (408) comprising at least one tangential fan (410) for setting in motion an air flow (F) intended to pass through the first heat exchanger (404), and wherein the first (404a) and second (404b) stages of the first heat exchanger (404) are arranged opposite each other, one behind the other with respect to the direction of flow of the air flow (F), so that the air set in motion by the tangential fan (410) successively passes through the first stage (404a) and then through the second stage (404b).

A heat radiation amount from the cooling water in the radiator is adjusted so that the temperature of the cooling water is less than a prescribed temperature that is a temperature higher than the threshold value if a load exerted on the internal combustion engine is not less than a predetermined load, while the heat radiation amount from the cooling water in the radiator is adjusted so that the heat radiation amount from the cooling water in the radiator is increased if the load exerted on the internal combustion engine is less than the predetermined load as compared with if the load exerted on the internal combustion engine is not less than the predetermined load.
