A vehicle cowl structure includes a cowl body, a cowl panel, an air outlet, and a gas-liquid separation mechanism. The cowl body has a recessed shape with an upper opening when viewed in a longitudinal direction thereof. The cowl panel closes the upper opening of the cowl body, and has an outside air inlet. The outside air inlet allows outside air to be introduced into the cowl body. The air outlet allows air inside the cowl body to be discharged toward a vehicle interior. The gas-liquid separation mechanism is disposed between the outside air inlet and the air outlet and allows the air and liquid inside the cowl body to be separated from each other. The gas-liquid separation mechanism includes a lower blocker, an upper blocker, and an air suction part. The air suction part allows the air inside the cowl body to be drawn out.

A plenum assembly for a vehicle includes a plenum body, a plenum grid coupled to the plenum body, the plenum grid including a grid surface having a plurality of grid openings and a separation member extending from the grid surface toward the plenum body, and a vent port including a side surface extending from the plenum body and a domed surface formed integrally with the side surface, the vent port including an edge defining a vent port opening in the side surface such that a flow of air passes through the vent port and through the plurality of grid openings in the grid surface.

A cowl grille comprises a member portion which extends in a vehicle width direction below a front windshield so as to receive water dripping from the front windshield, a cover portion which is positioned in front of a member portion and covers over an auxiliary equipment, a partition portion which extends downwardly from the cover portion and partitions a space where an engine is arranged from another space where the auxiliary equipment is arranged, and a cowl seal which extends in the vehicle width direction and contacts a bonnet so as to seal between a vehicle outside space and an engine room. The cowl seal is positioned at a front part of the member portion, and the cover portion is made of a plate member and provided to perform heat insulating between a space positioned above the cover portion and another space positioned below the cover portion.

An apparatus and a method are provided for a multiple inlet air box to communicate an airstream through an air filter to an air intake duct of an internal combustion engine of a vehicle. The multiple inlet air box is comprised of a housing that supports the air filter within an interior of the housing. A mount portion within the housing fixedly receives a base of the air filter. Multiple air inlets couple with corresponding air inlet ports of the vehicle to direct the airstream into the multiple inlet air box. A duct directs the airstream from the multiple air inlets to the interior of the housing. A conduit communicates the airstream from an interior of the air filter to the air intake duct of the internal combustion engine.

An air handling system for a heating, ventilation, and air conditioning system of a motor vehicle includes a conduit configured to convey air from the air handling system to a vent of the air handling system. A control door is rotatably disposed in the conduit. The control door selectively rotates between a first position and a second position. The first position blocks passage of the air flowing through the conduit. The second position blocks passage of the air flowing through a first portion of the conduit and allows the air to flow through a second portion of the conduit. A control feature is disposed in the second portion of the conduit to control at least one of a volumetric flow rate and a pressure of the air flowing through the second portion.
