Abstract: In one aspect, an aspiration system for a work vehicle includes an exhaust tube extending along a flow direction and an aspiration tube in flow communication with the exhaust tube at an aspiration zone of the exhaust tube such that the aspiration tube is configured to receive an aspirated airflow. The system also includes an airflow area modifier provided in operative association with the aspiration zone and actuatable to adjust a cross-sectional flow area of the exhaust tube within the aspiration zone. The system includes an actuator provided in operative association with the airflow area modifier such that the actuator is configured to alter an orientation of the airflow area modifier such that the cross-sectional flow area of the exhaust tube within the aspiration zone is adjusted.

Abstract: In one aspect, a method for adjusting torque limits for a work vehicle may include controlling, with a computing device, an operation of an engine of the work vehicle such that a torque output of the engine is maintained at or below a baseline engine torque limit. The method may also include receiving, with the computing device, an input associated with a current hydraulic power requirement of a hydraulic system of the work vehicle, and adjusting, with the computing device, a torque limit for the engine from the baseline engine torque limit to an adjusted engine torque limit based on the current hydraulic power requirement of the hydraulic system. In addition, the method may include controlling, with the computing device, the operation of the engine such that the torque output of the engine is maintained at or below the adjusted engine torque limit.

Abstract: In one aspect, a system for controlling the supply of hydraulic fluid to an implement of a work vehicle may generally include a pump, a control valve coupled to the pump and first and second fluid lines provided in flow communication with output ports of the control valve. The system may also include a pressure control valve provided in flow communication with the second fluid line that is configured to regulate a fluid pressure of the hydraulic fluid being supplied to a hydraulic cylinder of the implement. Additionally, the system may include a bypass fluid line configured to provide a flow path for hydraulic fluid between the pump and the second fluid line that is independent of the control valve and a load sensing line configured to provide an indication of the fluid pressure of the hydraulic fluid being supplied to the hydraulic cylinder.

The system may also include a pressure control valve configured to regulate a pressure of the hydraulic fluid being supplied to the control valve such that the hydraulic fluid is supplied to the control valve at a first pressure for raising at least one ground-engaging component of the implement and a second pressure for lowering the ground-engaging component(s). Moreover, the system may include a bypass line in fluid communication with the pressure control valve such that fluid diverted through the bypass line actuates the pressure control valve to adjust the fluid pressure of the hydraulic fluid supplied to the control valve between the first and second pressures.
