作业车辆及作业车辆的控制方法
摘要：
作业车辆具备发动机、废气净化装置、还原剂罐、发动机冷却水回路、分支路径、阀、接受部、阀控制部、风扇、散热器、恒温器和风扇控制部。废气净化装置对从发动机排出的废气中的氮氧化物进行净化。还原剂罐储存向废气净化装置供给的还原剂。发动机冷却水回路包括通过发动机的驱动而使用于对发动机进行冷却的发动机冷却水在循环路径中循环的水泵。分支路径从循环路径分支，为了通过发动机冷却水在与还原剂罐内的还原剂之间进行热交换而设置。阀对发动机冷却水相对于分支路径的供给进行控制。接受部接受操作者的操作指示。阀控制部按照操作者的由接受部接受到的操作指示，对阀指示开动作。风扇在发动机室内生成冷却风。散热器通过冷却风对发动机冷却水进行冷却。恒温器设置在循环路径与散热器之间，在发动机冷却水的温度成为了规定温度以上的情况下，为了向散热器供给发动机冷却水而进行开动作。风扇控制部按照操作者的由接受部接受到的操作指示，使风扇的转速上升。
摘要（英）：

A utility vehicle provided with: a reducing agent tank that stores a reducing agent to be supplied to an exhaust gas purification device that purifies nitrogen oxides in exhaust gas; an engine coolant circuit that includes a pump that circulates, in a circulation passage, engine coolant for cooling the engine; a branched passage that branches off from the circulation passage and that is provided so as to use the engine coolant to exchange heat with the reducing agent inside the reducing agent tank; a valve that controls the supply of the engine coolant to the branched passage; a valve control unit that instructs the opening of the valve in accordance with an operational instruction from the operator; a fan that generates a cooling airflow in the engine compartment; a radiator that uses the cooling air to cool the engine coolant; a thermostat that is provided between the circulation passage and the radiator, and that opens to allow the supply of engine coolant to the radiator when the temperature of the engine coolant reaches a prescribed temperature or higher; and a fan control unit that increases the rotational speed of the fan in accordance with an operational instruction from the operator.
