Abstract: A system for aspirating a pre-cleaner of a work vehicle may include a fluid conduit in flow communication with an outlet port of the pre-cleaner for receiving an aspirated airflow from the pre-cleaner. The system may also include a double-walled flow pipe having an inner tube that receives a primary fluid flow of the work vehicle. The double-walled flow pipe may also include an outer tube surrounding the inner tube such that an annular passage is defined between the inner and outer tubes. The annular passage may be in flow communication with the fluid conduit. When a vacuum is applied to the annular passage, the aspirated airflow may be drawn through the fluid conduit from the pre-cleaner and directed to the annular passage. The aspirated airflow flows through the annular passage as the primary fluid flow is being directed through the inner tube.

A plurality of openings are spaced around the circumference of the tube adjacent the porous wall and a plurality of vanes are formed at a connection junction adjacent one edge of the opening to form vanes extending inward at an acute angle relative to a plane between the connecting junction and the longitudinal axis of the tube. Preferably, the vanes are concave on the surface extending inward to promote more effective mixing.

Abstract: A system for cooling charge air and excess fuel for a turbocharged diesel engine includes a charge air cooler having an inlet body, a heat exchanger that is disposed downstream from the inlet body and an outlet body that is disposed downstream from the heat exchanger. The outlet body defines a flow passage in fluid communication with the heat exchanger. The system further includes a fuel passage that is in thermal communication with the flow passage of the outlet body. A method for cooling excess fuel from the turbocharge diesel engine is also disclosed herein.

Abstract: An under-hood mounting configuration for a work vehicle may generally include an air intake component positioned upstream of an engine of the work vehicle. The air intake component may include a wall having an exterior surface and an interior surface. The wall may define a cooling port extending between the exterior surface and the interior surface. In addition, the under-hood mounting configuration may include a control unit having a housing defining an upper surface and a lower surface opposite the upper surface. The housing may be mounted to the wall along the exterior surface such that the housing is positioned directly over at least a portion of the cooling port. When the airflow is directed through the air intake component, a portion of the airflow may flow through the cooling port and may be directed towards the lower surface of the housing.

Abstract: A work vehicle includes an engine and a hood enclosure at least partially surrounding the engine. The hood enclosure may include a front grille and a secondary grille spaced apart from the front grille. The hood enclosure may also at least partially define an airflow compartment. The work vehicle may also include a heat exchanger disposed in the airflow compartment between the front grille and the engine and at least one cooling fan disposed in the airflow compartment between the heat exchanger and the engine. The at least one cooling fan may generally be configured to generate a reversible airflow within the airflow compartment between the front grille and the secondary grille.

Abstract: An exhaust system for an off-road vehicle including an outlet port configured to release exhaust gas and an outlet stack disposed about the outlet port, in which at least a portion of the outlet stack is radially spaced from the outlet port to form a gap between the outlet stack and the outlet port. The outlet stack is configured to direct a flow of exhaust gas from the outlet port toward a distal end of the outlet stack. The exhaust system further includes an exhaust shield in close proximity or coupled to the outlet stack comprising at least one opening and an electronic control unit (ECU) disposed within the exhaust shield. The gap is configured to establish an airflow path from the at least one opening to a region of the outlet stack downstream from the outlet port, and the ECU is positioned within the airflow path between the at least one opening and the gap to facilitate cooling of the ECU.

Abstract: A liquid cooling system for a work vehicle may generally include an expansion tank and a deaeration line having a fluid conduit which fluidly couples the expansion tank to a component of the cooling system. The fluid conduit defines a flow passage therein and includes an upstream portion, a downstream portion and an intermediate portion where the intermediate portion is defined between the upstream and downstream portions. The flow passage within the intermediate portion has cross-sectional shape which restricts liquid coolant flow between the component and the expansion tank during operation of the work vehicle.

Abstract: An air intake system for a work vehicle is disclosed. The air intake system may generally include a filter assembly having a pre-cleaner configured to separate particulates from air received within the filter assembly. The pre-cleaner may define a pre-cleaner outlet. In addition, the air intake system may include a blower having a fan and a housing encasing the fan. The fan may be configured to create a vacuum such that the particulates separate from the air are expelled from the pre-cleaner outlet and flow into the housing. The housing may define a blower outlet through which the particulates are expelled from the housing. Moreover, the flow of particulates through the blower outlet may be oriented non-parallel to a rotational axis of the fan.
