Work vehicle with engine compartment and exhaust gas treatment arrangement
First Claim
1. A work vehicle, comprising:
- a cab;
an engine compartment disposed forwards of the cab, the engine compartment including a first lateral face portion and a second lateral face portion, the first and second lateral face portions disposed away from each other in a vehicle width direction;
an engine disposed in the engine compartment;
an exhaust gas treatment device having a first end adjacent the first lateral face portion and a second end adjacent the second lateral face portion and being disposed over the engine in the engine compartment;
a radiator disposed forwards of the exhaust gas treatment device in the engine compartment; and
a blower configured to generate an airflow passing through the radiator from back to front of the radiator,wherein the exhaust gas treatment device is slanted with respect to the vehicle width direction for increasing a distance between the first end of the exhaust gas treatment device and the radiator towards the first lateral face portion, andthe first lateral face portion includes an air inlet facing a space between the exhaust gas treatment device and the radiator.

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.
