Provided is a vehicle engine room structure to cause high-temperature air in an engine room to be discharged outside, regardless of the presence or absence of rushing air. The structure includes: a baffle plate including a curved portion to surround a turbocharger of a vehicle from behind, when disposed in a vehicle, and an extending portion continuous from the curved portion and extending upward, when disposed in the vehicle. The baffle plate is disposed between the turbocharger and a lower dash panel of the vehicle. The baffle plate further includes a lower fixing portion fixed to the lower dash panel. The baffle plate and the lower dash panel define an installation space therebetween, in which in-vehicle components are installed.

The present application discloses an engine room structure of a vehicle including:

a partitioning wall configured to partition a storage space in which an engine is stored from a piping space to form an intake passage for supplying air to a combustion chamber of the engine; and an intake pipe which partially forms the intake passage in the piping space, wherein the intake pipe extends along the partitioning wall, the intake pipe being integrally formed with the partitioning wall.

A method and apparatus for noise reduction in a semi-truck tractor. The semi-truck tractor has hood cowling that is carried on an upper hood support mounted to a firewall of the semi-truck tractor. The invention includes applying a resilient sleeve to the upper hood support to eliminate a noise generated by vibration of the hood cowling when supported by the upper hood support. The resilient sleeve has an opening at a proximal end of the sleeve. The sleeve is dimensioned to surround an exposed face of the upper hood support when mounted to the firewall. The resilient sleeve provides a low friction barrier between the hood cowling and the upper hood support with the hood cowling in a closed position and supported by the upper hood support.

A snap-fit engine cover assembly provides multiple customized panels that cover and protect critical engine components which are revealed upon removal of engine component covers. Removing the covers from the engine block may be necessary for repairs, rebuilding, and storage of the engine block. The panels are shaped and dimensioned to substantially match the contour of the formed openings and crevices. The edges of the panels are sufficiently resilient and have recessed grooves that form a snap-fit relationship with the perimeter of the engine component openings. In addition to the snap-fit mating, the panels have fastener apertures that align with engine block apertures; thereby enabling fasteners to pass through for reinforcing the attachment of the panels over the formed openings in the engine block. A cardboard rectangular panel is also used along the sidewall of the engine block to protect against paint when painting portions of the engine block.

A system for noise and vibration sealing of a vehicle while providing reduced impact resistance includes a block of compressible material positionable between a vehicle hood and a support structure of the vehicle. The block of compressible material may include an attachment surface configured to be secured to a portion of the vehicle and an impact surface formed opposite the attachment surface. The impact surface may be positioned in the vehicle to be contacted by the hood or support structure during an impact event. An exterior surface may extend between the attachment surface and the impact surface. A cavity may be formed in the exterior surface. The cavity may have a first inner surface and a second inner surface opposing the first inner surface, and may be shaped to accommodate crushing of the block of compressible material during the impact event.

Disclosed are an undercover for vehicles with high elasticity and rigidity and a method of manufacturing the same. The undercover for vehicles with high elasticity and rigidity may include a needle-punched nonwoven fabric having a multi-layer structure of felt layers including a first PET fiber and a low-melting-point PET fiber, and each of the felt layers may have improved tensile strength and have optimized fiber alignment, to thereby improve the binding between fibers, mechanical rigidity and elasticity, as well as to reduce the weight of components, improve durability and secure harmlessness and inline workability.

A utility vehicle powertrain enclosure includes an engine and a transmission mounted to a carrier under a utility vehicle cargo box and substantially enclosed by the carrier and a plurality of panels. The carrier has a forward end pivotably attached to a frame member of the utility vehicle, and sides flexibly connected to panels alongside the engine, and a rearward end mounted to the utility vehicle with a pair of suspension members.

A vehicle lower structure includes an internal combustion engine arranged in an engine compartment of a vehicle; a lower cover arranged below the internal combustion engine and formed so as to cover a lower portion of the engine compartment; and one or more baffle plates arranged between the internal combustion engine and the lower cover. The one or more baffle plates are located within a range of the width of the internal combustion engine in the engine compartment with respect to the front-rear direction of the vehicle. The one or more baffle plate protrude toward the lower cover from the side of the internal combustion engine or toward the internal combustion engine from the side of the lower cover with respect to the top-bottom direction of the vehicle. The one or more baffle plate are formed so as to extend to the left-right direction of the vehicle.

A system for noise and vibration sealing of a vehicle while providing reduced impact resistance includes a block of compressible material positionable between a vehicle hood and a support structure of the vehicle. The block of compressible material may include an attachment surface configured to be secured to a portion of the vehicle and an impact surface formed opposite the attachment surface. The impact surface may be positioned in the vehicle to be contacted by the hood or support structure during an impact event. An exterior surface may extend between the attachment surface and the impact surface. A cavity may be formed in the exterior surface. The cavity may have a first inner surface and a second inner surface opposing the first inner surface, and may be shaped to accommodate crushing of the block of compressible material during the impact event.

A soundproofing device for a transmission according to the present disclosure is provided to transmit the power of one or more prime movers (for example, internal combustion engine and electric motor). The soundproofing device includes a Helmholtz resonator including: a wall that forms a Helmholtz resonance chamber; and an opening formed in the wall so as to cause the Helmholtz resonance chamber to communicate with the outside of the Helmholtz resonance chamber. The wall includes a transmission case that accommodates the transmission and a housing of a component mounted on the transmission (for example, PCU housing). The Helmholtz resonance chamber is formed between the transmission case and the housing.
