Abstract:
An air intake system for a cab and engine of a vehicle is shown and described. In a preferred embodiment, dry, ambient air is provided to the cab and engine through a duct that is mounted to an inner surface of a vehicle hood such that the hood forms a top surface of the duct. The duct is relatively narrow across the width of the hood and flares into an air chamber on either side of the hood. An air inlet opening is provided on both sides of the hood such that outside air is drawn into the air chambers. The velocity of the air drops as it passes into and through the air chambers, causing the moisture in the air to separate and drain from the air chambers through an evacuator valve provided in the bottom surface of each chamber. Two openings are provided in the bottom surface of the duct. One opening sealingly engages an opening in the engine air cleaner and the second opening sealingly engages a cab air intake duct, when the hood is in a closed position.
