Abstract: 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.

Abstract: An after treatment system (ATS) for a vehicle having an ATS module includes, fluidly connected in series, an inlet, a Diesel Oxidation Catalysts (DOC), a urea mixer and a Selective Catalytic Reduction (SCR), and an outlet. The inlet is fluidly connected to an output of an engine of the vehicle and the outlet is fluidly connected to an outlet tube of the vehicle. The inlet, DOC, mixer, SCR and outlet are arranged to define a substantial rectangular path of a flow (F) of exhaust gases flowing in the ATS, with the inlet and the outlet being positioned at a same vertex of the substantial rectangular path of the flow (F).

Abstract: An after treatment system (ATS) module for a vehicle includes, fluidly connected in series, an inlet, a plurality of chemical reaction modules and an urea mixer module. The chemical reaction modules are arranged to define a substantial quadrangular path of a flow of exhaust gases flowing in the ATS module. The urea mixer module is perpendicular to all the plurality of chemical reaction modules. The ATS module also includes deflector means configured to impart a swirling motion to the flow before flow enters in urea mixer module.

Abstract: An after treatment system (ATS) for a vehicle includes, fluidly connected in series, an inlet, a urea mixer and an outlet. The inlet is fluidly connected to an output of an engine of the vehicle and the outlet is fluidly connected to an outlet tube of the vehicle. The urea mixer is provided with a dosing module, an inner element and an outer element. The inner element is configured such that a first flow of exhaust gas flow flowing from the inlet into the urea mixer flows into an first volume defined by the inner element. The outer element is configured such that a second flow flows in a volume defined between inner element and outer element, wherein the first and second flows rejoin together in a mixing chamber fluidly connected to the volume and to the first volume downstream with respect inner and outer elements.

Abstract: A fluid tank thaw system that includes a fluid tank that receives a first fluid. A heating element within the fluid tank that heats the first fluid. A magnetic stir system that stirs the first fluid within the fluid tank to increase a thaw rate of the first fluid. The magnetic stir system includes a magnetic stirrer within the fluid tank. The magnetic stirrer rotates within the fluid tank to agitate the first fluid. An electric coil changes polarity to rotate the magnetic stirrer.

Abstract: A system for cleaning a grille of a work vehicle may include a grille defining an inner side facing towards an interior portion of a work vehicle and an outer side facing towards an exterior of the work vehicle. The system may further include a plurality of nozzles fixed relative to the grille and being directed towards the inner side of the grille. Additionally, the system may include a pressurized fluid source configured to supply pressurized fluid to the plurality of nozzles. The pressurized fluid received by the plurality of nozzles is expelled from the plurality of nozzles and directed through the grille.

Abstract: An exhaust treatment system for a work vehicle includes a selective catalytic reduction (SCR) system configured to react a mixture of reductant/exhaust with a catalyst to generate a treated exhaust flow. The system also includes a flow conduit in fluid communication with an outlet of the SCR system for receiving the treated exhaust flow and an exhaust sensor positioned within the flow conduit downstream of the SCR outlet. The exhaust sensor is configured to detect an amount of an emission gas present in the treated exhaust flow. Additionally, the system includes a flow mixer positioned upstream of the exhaust sensor. The flow mixer includes first and second sets of swirler vanes configured to impart a spiraling flow trajectory to the treated exhaust flow flowing between the SCR outlet and the exhaust sensor, with the first set of swirler vanes being spaced radially from the second set of swirler vanes.
