摘要： An aftertreatment system for a work vehicle includes: a fluid injector configured to inject a treatment fluid; a selective catalytic reducer (SCR) substrate; and a mixer fluidly coupled to the fluid injector and the SCR substrate and including at least one scroll defining a scroll open area and configured to receive a flow of exhaust gas and the treatment fluid. The mixer has a fixed wall and a plate displaceably coupled to the fixed wall, the plate being associated with the at least one scroll such that a change in a flow rate of exhaust gas into the at least one scroll passively causes displacement of the plate to adjust a size of the scroll open area.

摘要： An exhaust treatment system for a work vehicle includes a reductant injector configured to inject an exhaust reductant into the engine exhaust flow flowing through a mixing conduit. A plurality of flow separation elements are located downstream of the reductant injector and are configured to separate a liquid reductant flow from an inner conduit wall of the mixing conduit for mixing with the engine exhaust flow flowing therein.

摘要： A cooling system includes a first frame, a second frame coupled to the first frame and positioned in front of a portion of first frame in a stacked arrangement, a first cooler supported by the first frame, a second cooler supported by the second frame, and a baffle system. The baffle system includes a bracket coupled directly to one of the first frame or the second frame, a baffle coupled to the bracket and positioned to facilitate selectively restricting airflow through at least a portion of at least one of the first cooler or the second cooler, and an actuator positioned to facilitate reconfiguring the baffle between a non-restrictive orientation and a restrictive orientation.

摘要： A system for cleaning an air intake screen of a work vehicle may include an engine air intake assembly having an air intake screen through which an airflow is directed for subsequent delivery to an engine of a work vehicle. The system may further include a nozzle provided in operative association with the engine air intake assembly and directed towards the air intake screen. Additionally, the system may include a pressurized fluid source configured to supply pressurized fluid to the nozzle. The pressurized fluid received by the nozzle is expelled from the nozzle and directed through the air intake screen.

摘要： A fluid tank that includes a housing. The housing includes a bottom wall, a top wall, and a side wall. The side wall couples the bottom wall to the top wall to define a cavity that receives and houses a liquid. A conduit guides liquid from a fluid source into the cavity. The conduit defines an inlet and an outlet. The outlet couples to the side wall. A vent coupled to the housing and to the conduit. The vent defines a vent inlet coupled to the housing and a vent outlet coupled to the conduit. The vent discharges gas from the housing into the conduit.

摘要： A system for controlling an airflow supplied to a cabin of a work vehicle may include a housing defining a mixing chamber and a recirculating chamber isolated from the mixing chamber. The mixing chamber is configured to receive fresh air via a fresh air inlet and recirculated air via a first recirculated air inlet, with the fresh air being mixed with the recirculated air within the mixing chamber to create a fresh/recirculated air mixture that is supplied through a mixed air outlet. The recirculating chamber is configured to receive recirculated air via a second recirculated air inlet and supply the recirculated air through a recirculated air outlet. Additionally, the system may include a gate movable relative to the first recirculated air inlet to adjust an amount of recirculated air supplied to the mixing chamber, and an actuator configured to actuate the gate relative to the first recirculated air inlet.

摘要： A vehicle including a cab having a frame with at least two support posts each including an airflow path therein and an airflow system supported by the cab and configured for increasing an airflow into the cab and decreasing a power consumption of the cab. The airflow system includes at least one air intake opening in the cab configured for intaking a fresh air, an air filter fluidly coupled to the at least one air intake opening, and an air outlet within the cab and fluidly coupled with the air filter. The fresh air flows into the at least one air intake opening, through each respective airflow path of the at least two support posts, is filtered by the air filter, and flows out through the air outlet into the cab.

摘要： In one aspect, an air intake system for a work vehicle may generally include a fan shroud, a fan disposed within the fan shroud, an intake duct for receiving a portion of the air drawn through a front grille of the work vehicle by the fan and a filter assembly in flow communication with the intake duct. The filter assembly may include a pre-cleaner defining a scavenge port. The system may also include an aspiration conduit coupled to the scavenge port and an aspiration scoop extending between an inlet end and an outlet end. The inlet end may be coupled to the aspiration conduit. The aspiration scoop may extend through a portion of the fan shroud such that the outlet end is positioned within the fan shroud at a location upstream of the fan. The outlet end may include an outlet opening defined by at least one curved wall.

摘要： A mixing conduit for use within an exhaust treatment system of a work vehicle. The mixing conduit is configured to receive engine exhaust and a mixture of engine exhaust and reductant. The mixing conduit includes an outer tube and an inner tube within the outer tube. Each tube extends lengthwise from upstream ends to downstream ends of the inner and outer tubes, respectively. The inner tube includes an exterior surface, and the outer tube includes an interior surface. The inner tube defines an inner flowpath within the inner tube. The outer tube and inner tube also define an outer flowpath radially between the exterior surface of the inner tube and the interior surface of the outer tube. The mixing conduit further includes one or more swirler vanes extending radially between the exterior surface of the inner tube and the interior surface of the outer tube and within the outer flowpath.

摘要： An operator cab for a work vehicle includes: a cab enclosure including a roof an operator chair disposed in the cab enclosure; at least one layer of noise-deadening material coupled to the roof; and a headliner coupled to the roof such that the at least one layer of noise-deadening material is at least partially disposed between the headliner and the roof. The headliner includes a noise-reflective material and a noise escape region that comprises at least one opening configured to allow sound waves to pass through the noise escape region into the at least one layer of noise-deadening material and reduce noise reflection by the headliner to the operator chair.
