A vehicle includes a chassis, a suspension system coupled to the chassis, a front axle, a first rear axle, and a second rear axle coupled to the chassis by the suspension system, and a powertrain coupled to the chassis and at least one of the front axle, the first rear axle, and the second rear axle. The powertrain is configured to drive the at least one of the front axle, the first rear axle, and the second rear axle. The chassis, the suspension system, the front axle, the first rear axle, and the second rear axle provide a payload capacity rating of at least 1,750 pounds. The vehicle has an overall width between 60 inches and 80 inches.

The invention relates to a an air supply arrangement (100) for supplying air from the atmosphere towards an internal combustion engine in a vehicle, the air supply arrangement comprising an air intake (101) for intake of air from the atmosphere, an air outlet (102) for outlet of air towards the internal combustion engine, and an air duct (103) for leading air from the air intake (101) in a downstream direction to the air outlet (102). A separator (200) is arranged in the air duct (103) so as to divide the air duct (103) into an upstream portion (104) and a downstream portion (105) for filtering of atmospheric air from debris by passage of said atmospheric air through the separator (200). The air supply arrangement (100) further comprises a compressed air delivery arrangement (300) being arranged to supply compressed air towards the separator (200) for cleaning the separator (200) from assembled debris.

An air filtration system comprises a filter housing that defines a collection chamber and includes an air inlet, an air outlet and a cleaning assembly opening in fluid communication with the collection chamber. The system also comprises a filter support mounted to the filter housing with each one of the air inlet and the air outlet being located on a respective side of the filter support; and a filter cleaning assembly mounted to the filter housing and including an actuation system; and a diaphragm assembly at least partially covering the filter cleaning opening. The diaphragm assembly vibrates upon actuation of the actuation system so as to displace air in the collection chamber to remove particulate matter from a filter engaged with the filter support. The present disclosure also concerns a combustion engine comprising an air filtration system and a method for cleaning an air filtration system.

An air filter system for a utility vehicle includes a filter housing, a coarse filter located on an inlet side and accommodated in the filter housing, a fine filter arranged downstream in a filter operating direction of an airflow to be cleaned, and a cleaning arrangement accommodated in the filter housing for purging dirt particles separated at least in the fine filter counter to the filter operating direction.

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.

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.

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.

A centrifugal air filter for an automotive system includes a plurality of single separators for setting an air flow passing therethrough in a turbulent motion and a separation area surrounding the plurality of single separators. The separation area receives particles from the air flow due to the centrifugal forces. A filter housing portion is located below a predefined or operation position for receiving particles from the air flow due to gravity, and an intake pipe is connected by an extraction line to a connecting pipe emerging on a filter housing and opening into the filter housing portion.

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 method of operating a cleaning process on a filter in a vehicle air intake includes passing air through the filter from an upstream side to a downstream side, and providing an exhaust duct having an inlet end adjacent the upstream side of the filter and an outlet end adjacent a cooling fan or other air-extraction device of the vehicle arranged to draw air through the exhaust duct from the inlet end to the outlet end. In a periodic cleaning subroutine, the rotational speed of the fan is increased from a first speed to a second speed, while a pulse of pressurized fluid is applied to a downstream side of the filter. The exhaust duct carries away material dislodged from the upstream side of the filter by the applied pulse, and the rotational speed of the fan is reduced to its original level.
