Systems and methods are disclosed herein for controlling cooling fans in a self-propelled work vehicle having a main frame supported by wheels or tracks. The cooling fans direct ambient air in accordance with at least one inlet in the main frame, and selectively operate in first and second opposing directions. A perception system is supported by the main frame and configured to provide perception data (e.g., perception data) corresponding to a field of vision which includes the at least one inlet and at least a portion of an associated working area. A controller obtains the perception data and automatically determines characteristics relating to contamination of the cooling system based at least On the perception data. The controller further generates output signals to the cooling fans based on at least one of the determined contaminant characteristics, for example a debris location, type, density, and/or quantity as relating to contamination of the cooling system.

A chassis and skin of a delivery Autonomous Ground Vehicle include discrete upper and lower thermal management systems. The lower thermal management system is indirect, as is moves air through a closed duct that is in contact with high-heat dissipating components via heat sinks. The upper thermal management system is direct, as it moves air into the interior cavity of the AGV to cool sensors and other electronic equipment.

Disclosed is an articulated harvesting combine of a forward power processing unit (PPU) and a rear grain cart, wherein the PPU carries dual axially mounted engines with oppositely opposed crankshafts with one toward the rear grain cart and the other engine away from the rear grain cart, there being no comingling of flywheel output power flow between the two engines.

A method of removing debris from a screen cover has a first mode of operation which includes: activating first and second fans to move first and second portions of air through screen cover and into a plenum, and moving the first and second portions of air from the plenum into a heat exchanger. A second mode of operation includes: deactivating the first fan for a first time period, activating the second fan for the first time period to move a third portion of air into the plenum, moving a first part of the third portion of air from the plenum into the heat exchanger during the first time period, and moving a second part of the third portion of air from the plenum through the screen cover during the first time period such that the second part of the third portion of air removes debris from the screen cover.

A front fender is provided in front of an air-cooled engine which is a drive source of a motorcycle. An air introduction hole which opens frontward is formed at a front part of a cylinder head of the air-cooled engine. A space around a plug attachment portion for a spark plug and a space in front of the cylinder head communicate with each other through the air introduction hole. A guide portion for guiding incoming wind toward the air introduction hole is formed at a rear part of the front fender.

A utility vehicle such as an agricultural tractor includes an engine, a heat exchanger, and a fan located under a hood. The hood is pivotable between a closed position and an open position. The fan is mounted to the hood such that, when in the closed position, the hood covers the engine and heat exchanger and the fan is positioned in an operable position to generate a cooling airstream through the heat exchanger. When the hood is in the open position, the fan is displaced from the operable position.

An electric vehicle comprises a vehicle chassis extending along a longitudinal axis and a rotatable vehicle drive axle disposed along a transverse axis and having opposed ends that are configured for attachment to a pair of opposed drive wheels. The electric vehicle also comprises a selectively movable electric propulsion motor comprising a rotatable motor shaft rotatable about a motor axis, the electric propulsion motor configured to be mounted within the vehicle chassis and operatively coupled to the rotatable vehicle drive axle and opposed drive wheels, the motor axis configured to be oriented in a substantially vertical direction.
