An air management assembly for a work machine, the air management assembly having a cooling orifice defined in a panel, a cooling fan generating a cooling airflow through the cooling orifice to a cooling package, at least one fixed screen positioned along an intake orifice, and a first baffle positioned at least partially between the cooling orifice and the intake orifice. Wherein, the first baffle directs the cooling airflow partially across the fixed screen to clear the fixed screen of debris.

An apparatus and a method are provided for an air filter cleaning wand for flushing contaminants from an intake air filter of an automobile engine. The air filter cleaning wand comprises a proximal flange, a conduit, and a distal end portion. The proximal flange is configured to receive a nozzle of a water hose. An interior of the conduit is in fluid communication with the proximal flange. The distal end portion comprises a plurality of longitudinally aligned vents in fluid communication with the interior of the conduit. Upon passing water through the water hose and into the conduit, pressurized water streams exit the vents along the distal end portion so as to flush contaminants from the air filter. The air filter cleaning wand advantageously is comprised of a material which is sufficiently durable and temperature resistant to retain its configuration during operation when coupled to pressurized water sources.

A precleaner system for an air intake system. The precleaner system includes precleaners each having flow paths that induce a rotation to air flow and separate out particulate matter. The particulate matter is ejected from an outlet port in each of the flow paths and out of a dust ejector. The precleaned air is collected into a plenum from each of the precleaners. The precleaned air can flow from the plenum to a precleaner system outlet and the precleaned air can be received by an air intake system. A cover can be used to block air flow through one of the precleaners to tune the precleaner system to the desired airflow.

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.

Systems for harvesting machines, transmissions for harvesting machines, and methods of operating systems for harvesting machines are disclosed herein. A system includes a drive unit, a cleaner unit, an aspirator, and a transmission. The drive unit is configured to produce rotational power in use of the system. The cleaner unit is fluidly coupled to the drive unit and configured to separate debris from air so that the air becomes cleaned air and provide the cleaned air to the drive unit in use of the system. The aspirator is fluidly coupled to the cleaner unit and configured to draw debris away from the cleaner unit and exhaust the debris in use of the system. The transmission is coupled to the drive unit and the aspirator.

In one aspect, an aspiration system for a work vehicle may include an exhaust tube extending defining an exhaust passage therein. The exhaust tube may include a venturi portion, with the exhaust tube further defining an aperture within the venturi portion of the exhaust tube. The system may also include an aspiration tube configured to be coupled between the exhaust tube and a separate component of the work vehicle. The aspiration tube may define an aspiration passage extending between the separate component and the exhaust tube. The aperture defined by the exhaust tube may fluidly couple the aspiration passage and the exhaust passage. Furthermore, the system may include a restrictor body positioned within the exhaust passage. As such, the restrictor body and the venturi portion may be configured to adjust a flow parameter of exhaust gases flowing through the exhaust passage.

Cleanable filters and methods of cleaning filters are described in the present application. The cleanable air filter includes a housing and a filter element installed in the housing. The filter element is configured to filter an operating fluid in a given application. The filter element is cleanable in-situ in the installed condition in the housing. The cleanable air filter further includes a cleaning fluid applicator configured to apply a cleaning fluid to the filter element while the filter element is in the installed condition in the housing such that the filter element is cleanable without being removed from the filter housing.

Assemblies, features, and techniques for pulse jet air cleaner assemblies and their operation are described. Techniques described include methodology and equipment for preferred pulse jet sequencing and operation.

The present invention generally relates to a process and apparatus for cleaning and removing particulate deposits in a particulate filter, in particular for the dry removal of ash deposits with a diesel particulate filter. Compared to the art known procedures, the method of the present invention is based on the provision of a two-stage process including a stage wherein the filter is exposed to a structural resonant frequency under pressure and a stage wherein the filter is exposed to a reverse flow. Combination of a structural resonance frequency with a reverse flow results in an efficient two-stage removal of the debris from the filter without causing any damage to the ceramic body of the filter.
