A sealing element (10) of a deformable material for sealing an opening in a wall (16), which separates two different chambers, comprises at least one aperture (12) which is arranged in a sealing first region (20) and is designed to receive a tube (14), and a yielding second region (24) which is designed to be pressed against the wall (16), wherein the second region (24) is differentiated from the first region (20) at least in part by an indentation (22).

A grommet configured to pass through a vehicle wall and an acoustic mat is provided. The grommet includes first and second sealing segments, a mounting segment, and a pass-through segment. A flange configured to abut the vehicle wall extends from the first sealing segment. The pass-through segment has a NVH flap that is configured to abut the acoustic mat. The grommet has a grommet installation coupling that includes a mounting hole in the flange for receiving a mounting stud that extends from the vehicle wall and an engagement member that engages the mounting stud. The engagement member applies an installation force to the flange, which moves the grommet longitudinally from a first installation position to a second installation position and pushes the NVH flap against the acoustic mat so that the NVH flap is deflected back toward the flange as the grommet moves to the second installation position.

A motor vehicle comprises a vehicle body, an engine compartment housing an engine, a bonnet movably coupled to the body and arranged to provide a closure member for the engine compartment, the bonnet being movable between open and closed conditions to allow access to the engine compartment, and an engine air intake duct having an orifice through which intake air may be drawn into the engine. The vehicle is provided with first and second air flaw paths whereby air may be supplied to the air intake duct. The first flow path comprises an air inlet aperture disposed at a front portion of the vehicle for receiving ram air and an air outlet aperture aft of the air inlet aperture, the air outlet aperture being provided in fluid communication with the air intake duct orifice. The second flow path is provided by a gap between a side edge of the bonnet and the body of the vehicle, whereby ambient air may be drawn through the gap to the air intake duct.

A sealing arrangement for sealing at least one opening in a wall for the insertion of at least one tube through the opening, in particular in a dividing wall of a motor vehicle, with a sealing body having at least one first lead-through opening, wherein the sealing body has a circumferential groove having at least one sealing lip arranged in the area of the groove and surrounding the sealing body, and with a frame carrying the sealing body, and with a first frame edge formed peripherally on the frame and projecting therefrom. The first frame edge engages in a first recess of the sealing body in an axial direction and radially inwardly of the at least one sealing lip.

A battery cooling duct for vehicles includes a battery case mounted on a center floor panel of a vehicle, an inlet duct configured such that cooling air from an interior of the vehicle is drawn into a first area of the battery case therethrough, and an outlet duct divided into a plurality of noise reduction parts including an expansion section and configured such that the cooling air introduced into the first area passes through a second area of the battery case and is discharged outside through the plurality of noise reduction parts.

An outlet duct system for a vehicle air-cooled battery includes: a first duct fluidly connected to a battery assembly disposed under a floor of a vehicle, and mounted on a top surface of the floor; and a second duct communicating with the first duct, and having an outlet opening through which air is discharged to the floor, wherein the second duct includes a plurality of holes provided in a portion thereof adjacent to the outlet opening, and each hole has a diameter less than an opening area of the outlet opening.

A system of an insulated passage in an electrically driven motor vehicle includes a passage which connects a first region to a second region, wherein the first region is air-permeable in the direction toward a battery of the motor vehicle and wherein the second region is air-permeable in the direction toward a passenger compartment of the motor vehicle. The system further includes an insulating element which includes an expanded material, wherein the expanded material closes the passage against the first region and wherein the expanded material is a one-component thermally cured epoxy resin composition.
