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.

A ventilation system is adapted to be used in a vehicle. The vehicle includes a vehicle body that defines an interior space. The ventilation system includes a vent pipe and a fan. The vent pipe is adapted to be disposed on the vehicle body, and has an outside communicating end via which the vent pipe is adapted to communicate with the outside of the vehicle body, and an inside communicating end via which the vent pipe is adapted to communicate with the interior space. The fan is disposed in the vent pipe, and is configured to be activated to produce airflow from the outside communicating end to the inside communicating end.

A hood air intake and water separation system includes a first separation chamber having a first inlet fluidly coupled to a hood intake vent of the vehicle, a first outlet, and at least one first drain opening. The first separation chamber is configured to separate water and air ingested through the intake and direct the separated water through the at least one first drain opening and direct the separated air through the first outlet. A second separation chamber includes a second inlet fluidly coupled to the first separation chamber first outlet, a second outlet, and at least one second drain opening. A third chamber includes a third inlet fluidly coupled to the second separation chamber second outlet, and a third outlet. The first and second separation chambers are configured to direct ingested water away from an airpath to the engine.

A hood air intake and water separation system includes a first separation chamber having a first inlet fluidly coupled to a hood intake vent of the vehicle, a first outlet, and at least one first drain opening. The first separation chamber is configured to separate water and air ingested through the intake and direct the separated water through the at least one first drain opening and direct the separated air through the first outlet. A second separation chamber includes a second inlet fluidly coupled to the first separation chamber first outlet, a second outlet, and at least one second drain opening. A third chamber includes a third inlet fluidly coupled to the second separation chamber second outlet, and a third outlet. The first and second separation chambers are configured to direct ingested water away from an airpath to the engine.

In one aspect of the present disclosure, a barrier is disclosed that is configured for connection to a vehicle dash assembly including an HVAC opening defined by a flange. The barrier includes a body that is configured to obstruct a flow of suds into the HVAC opening, and at least one clip that is supported on the body. The body includes open upper and rear portions to allow for continued airflow through the HVAC opening, and the at least one clip includes first and second clip members defining a receiving space therebetween that is configured to receive the flange such that the first and second clip members are positioned on opposite sides of the flange.
