EXHAUST DEVICE OF CONSTRUCTION MACHINE

摘要

An exhaust device for a machine is disclosed. The exhaust device may have an exhaust-gas purifying member and a cylindrical exhaust port disposed at a downstream end of the exhaust-gas purifying member. Further the exhaust device may have an exhaust passage member extending in a width-direction from a first end to a second end and disposed downstream of the exhaust port. The exhaust passage member may include a first outlet opening disposed adjacent the first end and a second outlet opening disposed adjacent the second end. The exhaust passage member may also include an inlet opening disposed between the first and second outlet openings. In addition, the exhaust passage member may include an exhaust passage leading from the inlet opening to the first outlet opening and the second outlet opening. a sectional flow area of the exhaust passage may be larger than a sectional flow area of the exhaust port.
