Abstract:
Either an exhaust gas treatment unit which treats exhaust gas from an engine or a working vehicle is provided with a selective catalytic reduction device, a connection pipe, a spray device, a first pipe section, a second pipe section, a first storage section, a second storage section, and a refrigerant pump. The spray device is mounted to the connection pipe and sprays a reducing agent into exhaust gas supplied to the selective catalytic reduction device. The first pipe section conducts a refrigerant to the spray device, the refrigerant cooling the spray device. The second pipe section discharges the refrigerant from the spray device. The first storage section is connected above the spray device to the first pipe section and stores a refrigerant. The second storage section is connected above the spray device to the second pipe section and stores a refrigerant. The refrigerant pump is driven by power obtained from the engine and supplies a refrigerant to the spray device through the first pipe section. The first pipe section extends upward toward the first storage section from the first connection section where the first pipe section and the spray device are connected. The second pipe section extends upward toward the second storage section from the second connection section where the second pipe section and the spray device are connected.
