摘要： A machine (2) is adapted for operation powered by any one of a plurality of interchangeable power sources (33). The machine (2) may include an undercarriage configured for supporting ground engagement members (4) that propel the machine (2) and an upper structure (6) rotatably supported on the undercarriage. The upper structure (6) may include a swing frame (22), with the swing frame (22) supporting an operator cab (24), any one of the plurality of interchangeable power sources, hydraulic components, electrical components, and a counterweight (126, 226) disposed at a first end of the swing frame. The counterweight (226) may include a hollowed out portion (222) facing toward the swing frame (22). The hollowed out portion (222) of the counterweight (226) may be centrally aligned with a center core portion (310) of the swing frame (22) configured for supporting any one of the plurality of interchangeable power sources (33), with the one power source being partially accommodated within the hollowed out portion (222) of the counterweight (226).

摘要： Provided is a machine body capable of preventing thermal decomposition of a liquid reducing agent in a reducing agent injector. The machine body includes an exhaust gas treatment device (24) that reduces nitrogen oxides in exhaust gas of an engine (21) provided within a machine room (19), and a reducing agent supplier (31) that supplies the liquid reducing agent to the exhaust gas treatment device (24). The exhaust gas treatment device (24) includes a reducing agent injector (28) that injects the liquid reducing agent supplied from the reducing agent supplier (31), and a cooling fan (35) that is installed in the vicinity of the reducing agent injector (28) so as to face the reducing agent injector (28). The cooling fan (35) performs cooling by blowing cooling wind of external air, which is taken in from the outside of the engine room (19), against the reducing agent injector (28) and its upstream side.

摘要： An injector injects urea water as a liquid reducing agent; a NOx sensor detects concentration of nitrogen oxide in exhaust gas; and an air duct including an inlet side opening and outlet side opening cools at least either one of urea water in urea water hose, NOx sensor or injector with cooling air introduced from outside of the machine room. A ventilation opening at the outside of the machine room communicates with the inlet side opening of the air duct using negative pressure formed in a circumference of exhaust gas flow by an ejector arranged in an exhaust pipe passage.
