CONSTRUCTION MACHINE PROVIDED WITH ENGINE ROOM
Disclosed is a construction machine comprising an engine room (5) having first (15) and second (16) exhaust ports, preventing deterioration of air flows due to collision of exhaust airs through the first (15) and the second (16) exhaust ports, and reducing noise transmission on lateral sides of the construction machine. The construction machine comprises an engine guard (4) surrounding an engine room (5); an engine (6), a heat exchanger (7), and a cooling fan (8), which are installed in the engine room (5); and an exhaust air guide (19). The engine guard (4) is formed with exhaust ports including the first (15) and second (16) exhaust ports. The first (15) is opened in parallel to an axial direction of an engine output shaft (6a). The second (16) is formed in proximity to the first exhaust port (15) downstream of the first exhaust port (15) with respect to a direction parallel to the axial direction of the engine output shaft (6a) and opened upward below the first exhaust port (15). The exhaust air guide (19) has a shape to change a flow direction of the air discharged through the first exhaust port (15) in parallel to the axial direction of the engine output shaft (6a) into an upward direction at a position upstream of the second exhaust port (16).
