Various embodiments for an exhaust gas treatment device for a vehicle system are provided. In one example, the vehicle system includes an engine with a longitudinal axis, where a crankshaft of the engine is parallel to the longitudinal axis and an exhaust gas treatment device mounted on the engine, vertically above the engine such that a longitudinal axis of the exhaust gas treatment device is aligned in parallel with the longitudinal axis of the engine, the exhaust gas treatment device configured to receive exhaust gas from an exhaust manifold of the engine.

Device, method, and system for emissions control

Various systems are provided for supporting an exhaust gas treatment system vertically above an engine in an engine system. In one example, an engine system includes an engine; a support structure including a base and a plurality of mounting legs, a first end of each mounting leg of the plurality of mounting legs coupled to the base and an opposite, second end of each mounting leg of at least a portion of the plurality of mounting legs coupled to the engine, where at least three mounting legs of the plurality of mounting legs and the base form two triangles within a same plane of the support structure; and an exhaust gas treatment system positioned vertically above and mounted on the engine via the support structure.

Apparatus and system for directing exhaust gas flow

A controller for controlling emission of an internal combustion engine, that is configured to: determine an aging parameter(s) of the engine over a period of time; control an operating parameter(s) of the engine, based on the aging parameter(s); and then maintain emissions from the engine at a substantially constant value, based on the controlling. Also method of controlling emissions of an engine comprises: over a time period, determining a change in operating hours of the engine; emissions of the engine; and/or quantity of a fuel being dispensed by a fuel nozzle; controlling an operating parameter(s) of the engine during the time period, based on the determining, thereby maintaining the emissions of the engine substantially at a constant level during the same time period. A system and non-transitory computer readable media for controlling emissions of an engine are also disclosed.

System for controlling emissions of engine and related method and non-transitory computer readable media

System for controlling emissions of an engine is disclosed. The system includes a controller to determine one or more aging parameters of the engine, and to control one or more operating parameters of the engine, at least, based on the one or more aging parameters, such that the emissions from the engine are maintained to be substantially constant during a useful life of the engine. Method and non-transitory computer readable media for controlling emissions of an engine are also disclosed.

System for controlling emissions of engine and related method and non transitory computer readable media

Various systems are provided for a support structure. In one embodiment, a system comprises a support structure including a plurality of support legs, a first end of each support leg of the plurality of support legs coupled to a respective cylinder head of a plurality of cylinder heads mountable to an engine block, the plurality of support legs configurable to support an exhaust aftertreatment system.
