System and method for adjusting air flow in an engine compartment of an off-road vehicle

1. An air flow control system for an off-road vehicle, comprising:

a first movable side panel configured to be positioned proximate to a first lateral side surface of a body of an engine hood of the off-road vehicle; and

a controller configured to:

receive a signal indicative of a temperature of an engine of the off-road vehicle;

access a desired engine temperature range from a storage device;

output a first control signal to instruct one or more actuators to move the first movable side panel laterally outward relative to the first lateral side surface of the body of the engine hood to enable a flow of air through a gap between the first movable side panel and the body of the engine hood when the first signal indicates that the temperature of the engine of the off-road vehicle is greater than the desired engine temperature range during operation of the engine;

output a second control signal to instruct the one or more actuators to move the first movable side panel to a closed position in response to shut-down of the engine of the off-road vehicle;

receive an operator input to close the first movable side panel via an input device; and

output a third control signal to instruct the one or more actuators to move the first movable side panel to a rear-facing open position in response to receipt of the operator input to close the first movable side panel while the signal indicates that the temperature of the engine of the off-road vehicle is greater than the desired engine temperature range during operation of the engine, thereby blocking debris and facilitating air flow under the engine hood, and wherein a rearward portion of the first movable side panel is positioned a first distance laterally outward from the first lateral side surface of the body of the engine hood and a forward portion of the first movable side panel is positioned a second distance, less than the first distance, laterally outward from the first lateral side surface of the body of the engine hood when the first movable side panel is in the rear-facing open position.

2. The air flow control system of claim 1 , wherein the one or more actuators comprises one or more of a hydraulic cylinder, a pneumatic cylinder, or an electric motor.

3. The air flow control system of claim 1 , comprising one or more bars coupled to and extending laterally inward from the first movable side panel, wherein the one or more bars include an adjustable portion configured to move relative to the body of the engine hood, and a stationary portion fixedly coupled to the body of the engine hood.

4. The air flow control system of claim 1 , wherein the first movable side panel is configured to move to an angled open position in which at least a portion of the first movable side panel is positioned laterally outward from the first lateral side surface of the body of the engine hood and in which the first movable side panel is oriented at an angle relative to the first lateral side surface of the body of the engine hood, wherein the angled open position is a rear-facing open position in which at least a rear portion of the first movable side panel is positioned laterally outward from the first lateral side surface of the body of the engine hood.

5. The air flow control system of claim 1 , comprising a second movable side panel configured to be coupled to a second lateral side surface, opposite the first lateral side surface, of the body of the engine hood of the off-road vehicle.

6. The air flow control system of claim 1 , wherein the controller is configured to instruct a display to provide a visual indication of at least one of a current position of the first movable side panel or a current movement of the first movable side panel.

7. The air flow control system of claim 6 , wherein the display is positioned within a cab of the off-road vehicle.

8. An air flow control system for an off-road vehicle, comprising:

a first movable side panel configured to be positioned on a first lateral side of a body of an engine hood of the off-road vehicle;

one or more bars extending laterally inward from the first movable side panel, wherein the one or more bars are configured to couple the first movable side panel to the body of the engine hood, and the one or more bars are telescoping bars comprising a stationary portion fixedly coupled to the body of the engine hood and an adjustable portion configured to slide relative to the stationary portion, wherein the one or more bars comprise at least one forward bar positioned proximate to a forward edge of the first movable side panel and at least one rearward bar positioned proximate to a rearward edge of the first movable side panel; and

one or more actuators coupled to the one or more bars and configured to move the adjustable portion of the one or more bars and the first movable side panel laterally outward relative to the first lateral side of the body of the engine hood in response to one or more signals from a controller of the air flow control system, wherein the at least one forward bar is coupled to a first actuator of the one or more actuators and the at least one rearward bar is coupled to a second actuator of the one or more actuators.

9. The air flow control system of claim 8 , wherein the first actuator is configured to adjust the forward bar to extend the forward edge of the first movable side panel a first distance laterally outward from the first lateral side of the body of the engine hood, and the second actuator is configured to adjust the rearward bar to extend the rearward edge of the first movable side panel a second distance, different from the first distance, laterally outward from the first lateral side of the body of the engine hood.

10. The air flow control system of claim 8 , comprising one or more slideable top panels configured to be positioned on a top surface of the body of the engine hood and to slide relative to the body of the engine hood between an open position in which at least a portion of an engine of the off-road vehicle is exposed and a closed position in which the portion of the engine is covered.

11. The air flow control system of claim 8 , comprising one or more hinged panels configured to be positioned proximate to a top surface of the body of the engine hood and to rotate relative to the body of the engine hood between an open position in which at least a portion of an engine of the off-road vehicle is exposed and a closed position in which the portion of the engine is covered.

12. The air flow control system of claim 8 , comprising a second movable side panel configured to be positioned on a second lateral side of the body of the engine hood, wherein the one or more actuators are configured to move the second movable side panel laterally outward relative to the second lateral side body of the engine hood in response to one or more signals from the controller of the air flow control system.
