Description
図1は、本実施の形態に係る作業機械の一例であるホイールローダの側面図であり、図2は、このホイールローダ100の後部車体を主に表した平面図である。図3は、ホイールローダ100の後部車体を斜め後方から見た斜視図であり、図4は、ホイールローダ100の背面図であり、図5は、後部車体を左側面から見た図である。
ホイールローダ100は、アーム111、バケット112、タイヤ113等を有する前部車体110と、運転室121、機械室(エンジン室)122、冷却器室126、タイヤ123等を有する後部車体120とで構成される。後部車体120の後方にはカウンタウェイト124が取り付けられている。エンジン室122の前方には、作動油タンク125が設けられている。
排気装置400を構成する各装置410,420,430は、各々の長手方向、すなわち延在方向が車両の略前後方向となるように配置されている。これにより、各装置410,420,430を限られたスペース内に配設できる。また、図8〜10より明らかなように、排気装置400では、酸化触媒装置410と尿素SCR装置430との間で、正面視および側面視において尿素水添加装置420を酸化触媒装置410および尿素SCR装置430よりも高い位置に配設した。これにより、酸化触媒装置410と尿素SCR装置430との左右、すなわち車幅方向の距離を縮めることができ、排気装置400の左右方向の幅を狭くすることができる。各装置410,420,430をコンパクトに配設できるので、各装置410,420,430をすべてエンジン室122内でエンジン301の上方に配設できる。その結果、運転室122の後方の建屋の大型化を抑制でき、運転室122からの後方視界が確保できる。
図7を参照して上述したように、エアクリーナ310は、冷却器室126内で、隔壁160の直後に設けられている。このように、エンジン室122とは隔壁160で隔てられた冷却器室126内にエアクリーナ310を設けることで、エンジン301や排気装置400からエアクリーナ310への熱の影響を抑制できる。これにより、エンジン301で吸入される空気の温度上昇を抑制して、エンジン301での吸気効率の低下を抑制できる。
本実施の形態では、図7に示すように、尿素水供給配管425は、エンジン室122内での配設距離が極力短くなるように配設されている。すなわち、尿素水供給配管425は、後部車体120の後部左側の尿素水タンク127からエンジン室122内の尿素水噴射弁421まで配設されるが、できる限り尿素水噴射弁421の近くまで冷却器室126内を通るように、その配設経路が設定されている。このようにすることで、エンジン301や排気装置400から尿素水供給配管425中の尿素水への熱の影響を抑制し、熱による尿素水の品質劣化を抑制できる。
(1)上述の説明では、第1排気装置401には酸化触媒装置410が用いられ、第2排気装置402には尿素水添加装置420が用いられ、第3排気装置403には尿素SCR装置430が用いられているが、これは一例であって、本発明はこれに限定されない。たとえば、各排気装置410,420,430に、排気ガスの浄化機能のない消音装置等の他の種類の排気装置が用いられてもよい。
(5)上述した各実施の形態および変形例は、それぞれ組み合わせてもよい。
