WIPO Patent Application WO/2014/007060
Kind Code:
A1
Abstract:
An exhaust-gas aftertreatment device (30) disposed on an engine (7) comprises a first aftertreatment unit (31) and a second aftertreatment unit (32), which are provided as a left and right pair and into both of which exhaust gas from the engine (7) flows in a divided manner. The first and second aftertreatment units (31, 32) are each provided with a first purification device (33) on the upstream side, a second purification device (34) on the downstream side, and a line of connection piping (35) for connecting the first and second purification devices (33, 34). The first and second purification devices (33, 34) of the units (31, 32) are arranged side by side in the left-right direction in such a manner that the flow direction of exhaust gas flowing in the first and second purification devices (33, 34) is parallel to the front-rear direction. In a view in the front-rear direction, an outer rectilinear envelope (E) in contact with both the first purification device (33) and the line of connection piping (35) of each of the units (31, 32) is tilted as the outer rectilinear envelope (E) extends upward, so as to extend toward the center of the engine (7) in the left-right direction.
