Embodiment Construction

[0046] Hereinafter, embodiments embodying the present invention will be described with reference to the drawings. In addition, in the following description, the exhaust gas inflow side is simply referred to as the left side, and similarly, the exhaust gas discharge side is simply referred to as the right side.

[0047] First, refer to Figure 1 to Figure 9 The overall structure of the exhaust gas purification device will be described. like Figure 1 to Figure 5 As shown in FIG. 1 , a continuously regenerative diesel particulate filter 1 (hereinafter, referred to as DPF) is provided as the exhaust gas purification device of the present embodiment. The DPF1 is used to physically trap particulate matter (PM) and the like in exhaust gas. DPF1 is in the direction of exhaust gas movement (from figure 1 Diesel oxidation catalyst 2 such as platinum that generates nitrogen dioxide (NO2) and a honeycomb structure soot filter that continuously oxidizes and removes captured particulat...

Abstract

The present invention aims to provide an engine device which allows a gas purifying filter (1) as a part constituting an engine (70) to be highly rigidly mounted to the engine (70), which eliminates the need that each device of a vehicle has countermeasures for exhaust gas, and which enhances the versatility of the engine (70). The engine device provided by the invention is provided with a diesel engine (70) having an exhaust manifold (71), and also with an exhaust gas purifying device (1) for purifying exhaust gas discharged by the diesel engine (70). Filter support bodies (19) for supporting the exhaust gas purifying device (1) are provided to the upper part of a flywheel housing (78) of the diesel engine (70). The exhaust gas purifying device (1) is connected to the exhaust manifold (71) and also connected to the flywheel housing (78) through the filter support bodies (19).

Description

technical field [0001] The present invention relates to an engine device for a working machine such as a backhoe, a forklift or a tractor, and more particularly, to a mounting structure of an exhaust gas purification device with respect to the engine. Background technique [0002] At present, in the exhaust path of a diesel engine, as an exhaust gas purification device (post-processing device), it is known to install a diesel particulate filter (or NOx catalyst), etc., and the exhaust gas discharged from the diesel engine is passed through the diesel particulate filter (or NOx catalyst). NOx catalyst) and the like to perform purification treatment (see Patent Document 1, Patent Document 2, and Patent Document 3). Also known is a technique in which a filter case (inner case) is provided in an outer case (outer case) and a particulate filter is arranged in the filter case (see Patent Document 4). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2000-145430 [0004] ...
