Engine device

Abstract

An issue of the present invention is to provide an engine device which is provided with an exhaust gas purification device, and which can be efficiently disposed in an engine installation space. A diesel engine 1 is provided with an exhaust gas treatment case 2 that treats exhaust gas, and an exhaust gas purification device 2 is disposed at an upper face side of the diesel engine 1. In addition, the engine device has a structure in which either the diesel engine 1 or the exhaust gas purification device 2 is provided with a temporary locking body 90, while the other one is provided with a temporary locking notch 92, in which a temporary locking body 87 or the temporary locking notch 92 is disposed below an attachment part of the diesel engine 1.

1 . An engine device comprising an exhaust gas treatment device that treats exhaust gas from an engine, in which the exhaust gas treatment device is disposed on an upper face side of the engine,
 wherein the engine device has a structure in which either the engine or the exhaust gas treatment device is provided with a temporary locking body, and the other one is provided with a temporary locking notch, and   wherein the temporary locking body and the temporary locking notch are disposed on a lower side of an attachment part of the engine.   
     
     
         2 . The engine device according to  claim 1 , wherein the engine device has a structure in which the exhaust gas treatment device is mounted on a flywheel housing, and a recirculation exhaust gas pipe as the attachment part extends between the engine and the exhaust gas treatment device. 
     
     
         3 . The engine device according to  claim 1 , wherein an exhaust outlet pipe is fixed to an exhaust manifold for the engine via a throttle device, and the exhaust outlet pipe is connected to an inlet pipe of the exhaust gas treatment device. 
     
     
         4 . The engine device according to  claim 3 , wherein the exhaust outlet pipe is S-shaped in planar view. 
     
     
         5 . The engine device according to  claim 1 ,
 wherein the engine device has a structure provided with an engine frame on which the engine and the like are mounted,   wherein an exhaust manifold installation portion of the engine is provided with an exhaust throttle device, and   wherein one side face of the exhaust gas treatment device, which faces the engine frame, and an outer side face of the exhaust throttle device are formed to be flush.   
     
     
         6 . The engine device according to  claim 5 , wherein one side face of the exhaust gas treatment device, and also an outer side face of an alternator with respect to an outer side face of the exhaust throttle device are formed to be flush. 
     
     
         7 . The engine device according to  claim 5 , wherein the exhaust throttle device is offset with respect to a gas inlet of the exhaust throttle device.
