Abstract

Two sets of assemblies are arranged such that a diesel particulate filter device of the assembly, a selective catalytic reduction device of the assembly, a selective catalytic reduction device of the assembly, and a diesel particulate filter device of the assembly are located next to each other in this order. Exhaust tubes are provided to extend upward from gas outlets of the selective catalytic reduction device of the assembly and the selective catalytic reduction device of the assembly. The two exhaust tubes are located on a virtual plane orthogonal to longitudinal directions of the selective catalytic reduction devices of the assemblies. Thereby, an air intake position for an engine can be easily set to a position from which exhaust gas from the engine is less likely to be taken in, in a configuration provided with two sets of assemblies.

First claim

The invention claimed is:

1. An engine unit, comprising:
an engine;
a first exhaust gas treatment device treating exhaust gas from said engine;
a second exhaust gas treatment device treating the exhaust gas that has passed through said first exhaust gas treatment device;
a third exhaust gas treatment device treating the exhaust gas from said engine;
a fourth exhaust gas treatment device treating the exhaust gas that has passed through said third exhaust gas treatment devic…
