Abstract

The present invention addresses the problem of providing an engine device which comprises an exhaust gas purification device and which is capable of being efficiently disposed within an engine mounting space. An engine (1) is disposed below an operator's seat (219) in such a manner that a flywheel housing (10) is located at the front of a traveling machine body (216). An exhaust gas purification device (2) is disposed behind the engine (1) and below a radiator (24). The engine (1) is connected, on the left side thereof, to an air cleaner (32) for taking in fresh air and is connected, on the right side thereof, to an exhaust pipe (72) which is connected to the air intake side of the exhaust gas purification device (2).

Description

technical field [0001] The present invention relates to an engine device such as a diesel engine provided with an exhaust gas purification device, and more specifically, to an engine device mounted on a working machine such as a wheel loader, a backhoe, or a forklift. Background technique [0002] Conventionally, a technique has been developed in which an exhaust gas purification device (diesel particulate filter) is provided in the exhaust path of the engine, and exhaust gas discharged from a diesel engine is purified by an oxidation catalyst or a soot filter of the exhaust gas purification device ( For example, refer to Patent Document 1). In addition, in recent years, as an environmental measure, even in the fields of working machines such as construction machines and agricultural machines, it has been required to install exhaust gas purification devices in diesel engines used in the machines (for example, refer to Patent Document 2). [0003] prior art literature [00...
