An apparatus includes a tank having an outer surface, and panels of insulative material. The panels are positioned over the outer surface of the tank and extend adjacent to one another to form seams. An expansion joint is formed between at least a first and a second of the adjacent panels to allow expansion of the tank.

A tank for safely storing a fuel in a high-pressure gaseous state, and a method for manufacturing the tank are provided. The fuel gas storage tank includes a composite material that forms a tank shell and a liner disposed under the composite material. In addition, the liner has a structure in which a metal coil is integrally formed within the liner.

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.

The straddle vehicle includes a front wheel, a rear wheel, at least one tank, an internal combustion engine, a seat, and a steering handle. The front wheel is a steering wheel. The rear wheel is a drive wheel arranged located rearward of the front wheel. The tank is configured to be filled with a gaseous fuel. The internal combustion engine generates power using gaseous fuel filled in the tank. The driver sits on the seat. The driver performs the steering operation to the steering handle. The center of gravity of the tank is located closer to the steering wheel with respect to the center of gravity of the internal combustion engine.

A pressure vessel may include a body formed of a polymeric material. The body may extend between a first end and a second end. The body may include a center column defining a first inner volume extending between the first end and the second end. A wall may be connected to the center column. The wall may surround the center column and define a second inner volume therebetween. The second inner volume may be disposed annularly around, and fluidly separate from, the first inner volume. The pressure vessel may also include a first end cap coupled to the center column at the first end and second end cap coupled to the center column at the second end. The first end cap may close off the first inner volume at the first end. The second end cap may close off the first inner volume at the second end.

An in-vehicle liquid hydrogen tank includes: an inner tank that stores liquid hydrogen; an outer tank that accommodates the inner tank; and a heat-insulation material that is arranged in a heat-insulation clearance as a clearance between the inner tank and the outer tank and holds the inner tank to be separated from an inner surface of the outer tank. The heat-insulation clearance has: a vacuum area that is not filled with the heat-insulation material; and an area that is filled with the heat-insulation material and thus allows the inner tank to be surface-supported by the heat-insulation material.

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 pressure vessel for vehicle for containing and selectively providing pressurized air. The pressure vessel includes a first end cap and a second end cap connected to the first end cap to define an inner volume. In one example, a central shell is positioned between and connected to the first end cap and the second end cap. The first end cap and the second end cap each include reinforcement ribs and a mount positioned on each end of the pressure vessel to mount the pressure vessel to a vehicle. In one example an insert is used to reinforce the air ports or a drain port in communication with an inner volume of the pressure vessel. A mold cavity die for forming an injection molded pressure vessel and a method for inserting a reinforcement in an injection molded pressure vessel is disclosed.
