An air intake screen debris cleaning system may include an intake screen through which air is drawn in a first direction for cooling, a reverse airflow generation system to create a reverse airflow in a second direction opposite the first direction to clear debris from the intake screen, a sensor to sense debris that is collected on the intake screen and a controller to activate the reverse airflow generation system based upon signals from the sensor. In one implementation, the sensor comprises an emitter to emit a sensor beam that extends along a face of the air intake screen and which does not intersect or pass through the air intake screen prior to being sensed.

A cleaning apparatus of a work machine for cleaning debris from a screen mounted to a door of an engine cooling assembly. The cleaning apparatus includes a duct extending along the screen and along a first side of the door. The duct includes a duct end located at the door. A vacuum assembly is configured to draw a vacuum through the duct, wherein the vacuum assembly is detachably connected with the duct end. An alignment mechanism includes an aligner that extends from the duct to a frame of the work machine. The alignment mechanism aligns the duct end with the vacuum assembly to provide a seal between the duct and the vacuum.

The present invention relates to a method for filling a cooling circuit (2) of a motor vehicle (3) with a coolant (4). A simple filling of the cooling circuit (2) with coolant (4) and an increased operational safety are achieved in that the cooling circuit (2) is initially filled with ion-free water (13) and thereafter with a passivating agent (16), and wherein thereafter the cooling circuit (2) is rinsed with ion-free water (13) and subsequently filled with the coolant (4).

The invention, furthermore, relates to a system (1) for filling a cooling circuit (2) of a motor vehicle (3) with coolant (4).

Cooling and debris mitigation systems for use with work vehicle powertrains include a pressurized air source, a plurality of impingement outlets positioned proximate the work vehicle powertrain, and a flow network fluidly coupling the pressurized air source to the impingement outlets. A first vortex tube is positioned in the flow network and configured to separate pressurized airflow received from the pressurized air source into a hot stream and a reduced temperature stream. The first vortex tube includes a vortex tube inlet fluidly coupled to the pressurized air source, an exhaust port through which the hot stream is discharged, and a nozzle through which the reduced temperature stream is discharged. The reduced temperature stream impinges upon at least one of the targeted exterior regions of the work vehicle powertrain to provide cooling thereto and reduce debris accumulation thereon.

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.
