<P>PROBLEM TO BE SOLVED: To improve productivity and reduce manufacturing cost by efficiently arranging two exhaust gas posttreatment systems in a limited space around an engine. <P>SOLUTION: A PM collecting device 16 is arranged so as to extend in a vertical direction, and an NOx purification device 19 is arranged so as to extend in a horizontal direction. Therefore, even if it is difficult to secure a large installation space only in the horizontal direction as in the surrounding of the engine 8, a small space extending in the vertical direction can be secured and the PM collecting device 16 can be arranged in this space. While, in a proximity of the PM collecting device 16, a small space extending in the horizontal direction can be secured and the NOx purification device 19 can be arranged in this space. Thus, the PM collecting device 16 and NOx purification device 19 can be easily arranged around the engine 8. <P>COPYRIGHT: (C)2013,JPO&INPIT |
