摘要： A work machine provided with an exhaust gas purifying device includes a selective catalytic reducing device that performs treatment on exhaust gas of an engine, and a reducing agent injection device that injects a reducing agent into exhaust gas to be supplied to the selective catalytic reducing device. The work machine is provided with a housing that delimits an engine room accommodating the engine and the exhaust gas purifying device. The housing includes a top board that covers the engine room above the engine, and an exhaust duct that is provided in the top board and discharges the air in the engine room to the outside of the engine room. A part of a reducing agent supply pipe for guiding the reducing agent to the reducing agent injection device is disposed in the exhaust duct in a position above the reducing agent injection device.

摘要： An oxidation catalyst device is placed so that a central axis of the oxidation catalyst device may be oriented along a right and left direction of a work vehicle; a reducing agent injection device is placed so that a central axis of the reducing agent injection device may be oriented along a front and rear direction of the work vehicle; and a selective catalytic reduction device is placed so that a central axis of the selective catalytic reduction device may be oriented along the front and rear direction of the work vehicle, in which the oxidation catalyst device, the reducing agent injection device, and the selective catalytic reduction device are arranged so as to have a relationship that the central axes thereof become the same in height, and the central axis of the selective catalytic reduction device is placed so as to pass through the oxidation catalyst device.
