    Abstract: A pivoting work vehicle includes an engine, an exhaust gas treatment apparatus, and a hood. The exhaust gas treatment apparatus is configured to treat exhaust gas from the engine. The hood is configured to cover the engine and the exhaust gas treatment apparatus. The exhaust gas treatment apparatus includes a DPF device and an SCR device. The exhaust gas is treated first by the DPF device, then by the SCR device. The DPF device and SCR device are each disposed so that the lengthwise directions thereof lie along the vertical direction. The DPF device and SCR device are arranged side-by-side in a direction orthogonal to the vertical direction.

    Abstract: An aftertreatment system for treating constituents of an exhaust gas includes: a housing defining a first internal volume and a second internal volume; an oxidation catalyst in the first internal volume and extending along a first axis, the oxidation catalyst configured to receive at least a portion of the exhaust gas via an inlet conduit fluidly coupled to the oxidation catalyst; a filter in the first internal volume and extending along a second axis parallel to and offset from the first axis, wherein an outlet of the filter is disposed within the second internal volume and configured to emit the exhaust gas into the second internal volume; at least one selective catalytic reduction (SCR) catalyst in the second internal volume and extending along a third axis that is perpendicular to the first axis; and a decomposition tube in the second internal volume in a direction parallel to the third axis.

    Abstract: An exhaust gas aftertreatment system includes a housing assembly, a first catalyst member, and a second catalyst member. The housing assembly includes an upstream housing, a decomposition housing, a distributing housing, and a catalyst member housing. The upstream housing is centered on an upstream housing axis. The decomposition housing is coupled to the upstream housing and configured to receive exhaust gas from the upstream housing. The distributing housing is coupled to the decomposition housing and configured to receive the exhaust gas from the decomposition housing. The catalyst member housing is coupled to the distributing housing and configured to receive the exhaust gas from the distributing housing. The catalyst member housing is centered on a catalyst member housing axis that is parallel to the upstream housing axis. The first catalyst member extends within the catalyst member housing.
