    • PURPOSE: An attachment structure of an exhaust gas after treatment device for an agricultural vehicle is provided to install a bracket without changing a structure of an engine room or processing an engine case. CONSTITUTION: An attachment structure of an exhaust gas after treatment device for an agricultural vehicle comprises an exhaust gas after treatment device inside an engine room to purify exhaust gases from an engine. The exhaust gas after treatment device comprises a fixing member. The fixing member is placed parallel to an engine in an upper part of an exhaust manifold of the engine. A turbo charger(150) is placed in a lower part of exhaust gas inlet(210). The load of exhaust gas after treatment device is supported between the engine and the exhaust gas after treatment device. The fixing member comprises a bracket installed between a back side cylinder head(121) and a connection part(161) of a flange pipe(161).
    • 目的:提供一种用于农用车辆的废气处理装置的附接结构,以安装支架而不改变发动机室的结构或处理发动机壳体。 构成:用于农用车辆的处理装置之后的废气的安装结构包括在发动机室内的废气后处理装置,以净化来自发动机的废气。 废气处理装置包括固定构件。 固定构件平行于发动机放置在发动机的排气歧管的上部。 涡轮增压器(150)被放置在排气入口(210)的下部。 处理装置后排气的负荷被支撑在发动机和处理装置后的废气之间。 固定构件包括安装在后侧气缸盖(121)和凸缘管(161)的连接部分(161)之间的支架。

    • An entrance chamber (40) and exit chamber (50) for exhaust gas are constructed as an integrated inflow/outflow section (80), and a first post treatment device (10) having a DPF (13) at its central part and second post-treatment device (20) having a urea DeNOx catalyst (23) on its outer periphery side are constructed as an integrated catalyst installation section (70). The catalyst installation section (70), the inflow/outflow section (80), and a communication chamber forming section (30) are provided as separate bodies so as to be removable from each other, and the catalyst installation section (70) is made installable in a reversible manner. As a consequence, when the catalyst installation section (70) is reversed, the DPF (13) can be easily reversed without removing it from the central part, and further, when even the urea DeNOx catalyst (23) is also reversed at the same time, the direction of inflow of exhaust gas can be changed, thereby irregular deterioration of the urea DeNOx catalyst (23) can be prevented.
    • 作为排出气体的入口室(40)和出口室(50)构成为一体的流入流出部(80),在其中央部具有DPF(13)的第一后处理装置(10) 在其外周侧具有尿素脱硝催化剂(23)的处理装置(20)构成为集成催化剂安装部(70)。 催化剂安装部分(70),流入/流出部分(80)和连通室形成部分(30)被设置为分离的主体以便彼此可拆卸,并且催化剂安装部分(70)被制成 以可逆的方式安装。 结果,当催化剂安装部(70)反转时,DPF(13)可以容易地反转而不从中心部分移除,此外,即使在同样的情况下,即使尿素脱硝催化剂(23)也反转 时间可以改变排气的流入方向,从而可以防止尿素脱硝催化剂(23)的不规则的劣化。
