A working vehicle includes an engine, an air blowing device, an exhaust gas post-processing device, and a guide device. The air blowing device is disposed in front of the engine. The exhaust gas post-processing device processes exhaust gas from the engine, and is disposed above the engine. The guide device lifts and guides at least portion of the air from the air blowing device to an upper side where the exhaust gas post-processing device is provided.

Working vehicle

A dump truck includes: a main frame that extends in a front-back direction of a vehicle body; an engine installed on the main frame; an exhaust aftertreatment device that is supported by the main frame and purifies exhaust gas from the engine; and a communication pipe having a first end connected to the engine and a second end connected to the exhaust aftertreatment device, in which the exhaust gas discharged from the engine flows to the exhaust aftertreatment device. The communication pipe includes: an upstream pipe extending from the engine to a lateral side thereof; a bellows pipe angularly connected to the upstream pipe and extending in an up-down direction; and a downstream pipe angularly connected to the bellows pipe.

Exhaust configuration for a vehicle

A dump truck includes: a main frame; an engine installed in the main frame; and an exhaust aftertreatment device that purifies exhaust gas from the engine. The main frame includes a vertical member in a portal shape which projects in a vehicle height direction of the dump truck and extends in a vehicle width direction of the dump truck. The exhaust aftertreatment device is supported by the vertical member. With this arrangement, maintenance of the engine can be conducted while the exhaust aftertreatment device is kept attached to the vertical member.
