Work vehicle with diesel particulate filter

摘要

A work vehicle includes a cooling fan, an engine, and a diesel particulate filter (DPF) purifying exhaust gas of the engine, placed under a hood in that order, beginning at the front. Exhaust gas from the engine is exhausted through an exhaust passage after passing through the DPF. The cooling fan supplies cooling air to the rear. The DPF is placed such that a length direction thereof follows a width direction of a vehicle body. The exhaust passage includes a first passage, a second passage, and a third passage. The first passage extends forward and upward from the DPF before extending along the length direction thereof on a front side of the DPF. The second passage extends downward from a downstream portion of the first passage. The third passage extends to the rear from a downstream portion of the second passage and also includes an exhaust outlet.

1. A work vehicle comprising, at a rear portion of a vehicle body, a cooling fan, an engine, and a diesel particulate filter which purifies exhaust gas from the engine,
the work vehicle being configured such that the exhaust gas from the engine is exhausted through an exhaust passage extending from the diesel particulate filter after passing through the diesel particulate filter, wherein the cooling fan, the engine, and the diesel particulate filter are placed in that order from a front direction in a front-rear direction of the vehicle body, the cooling fan is placed so as to supply cooling air to the rear while the diesel particulate filter is placed such that a length direction of the diesel particulate filter follows a width direction of the vehicle body, and the exhaust passage comprises: a first passage extending forward and upward from the diesel particulate filter before extending along the length direction of the diesel particulate filter on a front side of the diesel particulate filter; a second passage extending downward from a downstream portion of the first passage; and a third passage extending to the rear from a downstream portion of the second passage and having an exhaust outlet.
