A fuel tank for a motor vehicle includes at least two parts that are joined together, each part being formed by an injection moulding process. The two parts form a receiving chamber for receiving fuel and form at least one other receiving chamber, the receiving chamber and the other receiving chamber being spatially separated by a portion of at least one part.

A tank made of resin provided with a barrier layer, which prevents the barrier layer from rolling up and has improved durability. In a tank made of resin that includes a barrier layer provided on an inner surface of a tank body made of resin, an opening part is provided in the barrier layer, a thick part projecting toward an inside or an outside of the tank body is provided in a resin layer at an outer peripheral part of the opening part, and the barrier layer and a casting flange part at a base of an oil filling port tubular part are molded with the resin of the tank body in a state in which the casting flange part is located at the thick part.

A compartment for storing fuel in a vehicle having a protective outer structure and an inner structure. The protective outer structure is maintained in position relative to the vehicle during normal operation of the vehicle. The inner structure, which holds fuel, is positioned in the outer structure. The inner structure is maintained in position relative to the outer structure and relative to the vehicle during normal operation of the vehicle. During an impact to the vehicle, the inner structure is configured to move independent of the outer structure.

A vehicle shown herein is a side by side utility vehicle having frame configured to effectively transfer various loads throughout the frame as whole. The vehicle may further or alternatively include a routing tray configured to retain various fluid lines of the vehicle, a transmission including a passive duct acoustical attenuation device, a door seal configured to allow the frame to contact the seal at an angle, a modular door actuating mechanism, and/or a modular skid plate.

A compartment for storing an energy source in a vehicle having a protective outer structure and an inner structure. The protective outer structure is maintained in position relative to the vehicle during normal operation of the vehicle. The inner structure, which holds the energy source, is positioned in the outer structure. The inner structure is maintained in position relative to the outer structure and relative to the vehicle during normal operation of the vehicle. During an impact to the vehicle, the inner structure is configured to move independent of the outer structure.

A dual-fuel tank houses one or more compressed natural gas (CNG) vessels and one or more diesel fuel vessels. The diesel fuel vessels are generally disposed laterally outwardly from the CNG vessels to provide a buffer that protects the CNG vessels from side impacts. The dual-fuel tank may be retrofit onto a diesel locomotive in place of the locomotive's diesel fuel tank to convert the locomotive into a dual-fuel locomotive. The dual-fuel tank may be provided in a ship.

An operating fluid container for a motor vehicle for accommodating an operating fluid. The operating fluid container has a compensation container that is at least indirectly fluidically connected to the atmosphere (ATM). The operating fluid container has the following features: the compensation container is situated within the operating fluid container in such a way that an outer surface of a compensation container upper shell is situated opposite from an inner surface of an operating fluid container upper shell; in the event of positive pressure in the operating fluid container relative to the atmosphere, a compensation container volume decreases; and in the event of negative pressure in the operating fluid container relative to the atmosphere, the compensation container volume increases. The operating fluid container is characterized in that the compensation container upper shell opposite from the operating fluid container upper shell has a shape, at least in sections, that is complementary to the operating fluid container upper shell.

A fuel tank in a vehicle. The fuel tank includes a protective outer shell and an inner shell. The protective outer shell has an inner shell receiving area. The inner shell, which holds fuel, is housed in the inner shell receiving area of the outer shell. The inner shell cooperates with the outer shell to maintain the position of the inner shell relative to the outer shell and relative to the vehicle during normal operation. During an impact to the vehicle, the inner shell moves independent of the outer shell and the vehicle, allowing a portion of the energy or the forces associated with an impact to be absorbed by the outer shell, reducing the energy or force transferred to the inner shell.

A method for manufacturing a fuel tank is described herein. The method includes subsequent to molding of a housing of a fuel tank, positioning a strut inside the housing. The method additionally includes snap-fitting a flexible projection of the strut with a corresponding flange section in a first wall of the housing, the flange section surrounding an opening in the first wall of the housing and the flexible projection including a surface overlapping an interior surface of the flange section subsequent to the snap-fitting.

A composite pressure vessel that includes a monolayer liner and a reinforcing structure arranged on top of the liner. The liner is made by injection moulding and includes at least two shells weldable together. Each shell is made of a polymer composition including at least 45% by weight of an aromatic polyamide relative to the total weight of the polymer composition, and at least 10% by weight of an aliphatic polyamide relative to the total weight of the polymer composition.
