Air intake system for an off-road vehicle

A method of operating an air intake system for an off-road vehicle:

• receiving a first signal indicative of an air intake flow rate of an engine of the off-road vehicle at a processor;
• determining, using the processor, a target number of open tubes for a pre-cleaner of the air intake system based at least in part on the air intake flow rate and a desired flow rate for each tube of a plurality of tubes of the pre-cleaner;
• and
• outputting, using the processor, a second signal to a component of the air intake system indicative of instructions to enable the flow of air to the target number of open tubes and to block the flow of air to the remainder of tubes of the plurality of tubes.

An air intake system for an off-road vehicle comprising:

• a pre-cleaner comprising a plurality of tubes configured to receive a flow of air and to filter particulate material from the flow of air;
• and
• a cover disposed proximate to an upstream surface of the pre-cleaner and configured to move relative to the plurality of tubes to enable the flow of air to a target number of open tubes and to block the flow of air to the remainder of tubes of the plurality of tubes,
• wherein the cover comprises layered shields configured to stack relative to one another.

• and
• a controller configured to instruct an actuator to move the cover based at least in part on an air intake flow rate of an engine of the off-road vehicle and a desired air flow rate of each tube of the plurality of tubes.

An air intake system for an off-road vehicle comprising:

• a pre-cleaner comprising a plurality of tubes configured to receive a flow of air and to filter particulate material from the flow of air;
• and
• a cover disposed proximate to an upstream surface of the pre-cleanser and configured to move relative to the plurality of tubes to enable the flow of air to a target number of open tubes and to block the flow of air to the remainder of tubes of the plurality of tubes,
• wherein the cover comprises layered shields slidingly coupled to a track supported by an outer wall of the pre-cleaner.

An air intake system of for an off-road vehicle comprising:

• a pre-cleaner comprising a plurality of tubes configured to receive a flow of air and to filter particulate material from the flow of air;
• and
• a cover disposed proximate to an upstream surface of the pre-cleaner and configured to move relative to the plurality of tubes to enable the flow of air to a target number of open tubes and to block the flow of air to the remainder of tubes of the plurality of tubes,
• wherein the cover comprises layered radial shields extending radially outward from a center portion of the pre-cleaner to an outer wall of the pre-cleaner.
