Problems solved by technology

Therefore, as described above, if the exhaust gas treatment device is housed in the engine room of the work vehicle, the space in the engine room will be narrowed.
In this case, the ventilation resistance of the air sent to the radiator increases, and as a result, the cooling efficiency of the radiator may decrease.

Abstract

In a work vehicle, an engine compartment is disposed forwards of a cab. An exhaust gas treatment device is disposed over an engine in the engine compartment. A radiator is disposed forwards of the exhaust gas treatment device (33) in the engine compartment. A blower is configured to generate an airflow passing through the radiator from back to front of the radiator. The exhaust gas treatment device is slanted with respect to a vehicle width direction for increasing a distance between the exhaust gas treatment device and the radiator towards a first lateral face portion. Further, the first lateral face portion includes air inlets facing a space between the exhaust gas treatment device and the radiator.

Description

technical field [0001] The invention relates to a work vehicle. Background technique [0002] The work vehicle includes an engine room on the front side of the cab. The engine compartment accommodates devices such as an engine, a radiator, and a blower. For example, as shown in Patent Document 1, an exhaust pipe is connected to an engine via a muffler, and the exhaust pipe protrudes from the ceiling of the engine room. The radiator is arranged on the front side of the engine. The blower generates an airflow that flows through the radiator in order to cool the coolant flowing through the radiator. In addition, a plurality of ventilation holes are provided on the side of the engine room. Here, the work vehicle performs various works with a work device such as a scraper provided at the front of the vehicle body, such as a bulldozer. In such a work vehicle, foreign matter such as dust easily enters the engine compartment from the front of the vehicle body. Therefore, in su...
