Abstract:
1. A motor vehicle equipped with an internal combustion engine held in a storage space provided in a vehicle front portion, the motor vehicle comprising: a heat exchanger provided in proximity to a forefront of the storage space and arranged to perform heat exchange between a cooling liquid used for cooling down the internal combustion engine and outside air; a first outside air introduction assembly arranged to introduce the outside air from the forefront of the storage space into the heat exchanger during driving of the motor vehicle; a second outside air introduction assembly arranged to introduce the outside air from the forefront of the storage space into the internal combustion engine during driving of the motor vehicle; a first adjustment assembly arranged to regulate an amount of the outside air to be introduced into the heat exchanger by the first outside air introduction assembly; and a second adjustment assembly arranged to regulate an amount of the outside air to be introduced into the internal combustion engine by the second outside air introduction assembly; an engine cooling liquid temperature detection unit designed to detect temperature of the cooling liquid in the internal combustion engine as an engine cooling liquid temperature; and a controller configured to control the first adjustment assembly to increase the amount of the outside air to be introduced into the heat exchanger with an increase of the detected engine cooling liquid temperature from a first temperature that is an upper limit of temperature range in which the cooling liquid is not supplied to the heat exchanger, the controller controlling the second adjustment assembly to increase the amount of the outside air to be introduced into the internal combustion engine with an increase of the detected engine cooling liquid temperature from a second temperature that is lower than the first temperature.
