Abstract
In one aspect, an aspiration system for a work vehicle includes an exhaust tube extending along a flow direction from an upstream end to a downstream end. The exhaust tube defines an exhaust passage extending from the upstream end of the exhaust tube to the downstream end of the exhaust tube. The exhaust tube includes a venturi portion. The aspiration system also includes an aspiration tube in flow communication with the venturi portion and configured to receive an aspirated airflow. The system further includes a flow adjustment mechanism provided in operative association with venturi portion such that the flow adjustment mechanism is configured to adjust a cross-sectional flow area of the venturi portion of the exhaust tube.
