    Abstract: 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.

    Abstract: To reduce increase of the temperature of a control device of a supercharger and increase the lifetime of the control device of the supercharger, a work machine includes a variable geometry supercharger having changeable supercharge pressure and a working device. The work machine includes a variable displacement work hydraulic pump configured to be driven by an engine and supply pressure oil to an actuator configured to drive the working device; a supercharger control device configured to control the supercharger; a temperature detection device configured to detect the temperature of the supercharger control device; and a main control device configured to restrict, in case the temperature of the supercharger control device is higher than a first temperature, a maximum absorbing torque of the work hydraulic pump as compared to case the temperature of the supercharger control device is lower than the first temperature.
