A refuse vehicle includes a chassis having an engine, a body assembly, a tailgate pivotally attached to the body assembly, a CNG fuel system having a CNG fuel tank coupled to the tailgate and moveable therewith, the engine configured to be powered by the CNG fuel system, at least one of a non-structural conduit, a non-structural raceway, and a non-structural channel configured to contain at least one of wiring and a hydraulic line, and an impact mitigation system. The impact mitigation system is a passive system configured to direct impact loads around the CNG fuel tank. The impact mitigation system provides a protected region within which the CNG fuel tank is disposed.

An inerting system of a fuel tank of an aircraft includes an air separation module supplied at the inlet with air at a certain pressure to generate at the outlet an inert gas to be injected into the fuel tank comprising a certain flow rate and a certain oxygen concentration. A control method includes, at a given instant and at a constant air temperature and atmospheric pressure, (1) reducing the inert gas flow rate to a determined value, and (2) reducing the air pressure in order to cause an increase in the oxygen concentration from an initial value to a determined value. Decreasing the inert gas flow rate is performed by compensating for a loss of inert gas flow caused by the air pressure reduction, and decreasing the air pressure is performed by compensating for a reduction in the oxygen concentration caused by the inert gas flow rate reduction.

A container that provides for control of fluid flow in the event of a failure of the container is disclosed. In accordance with embodiments of the present invention, a container is presented that includes a container wall; and one or more flow impeding structures coupled to the container wall, wherein at least one of the one or more flow impeding structures is a multi-sheet layer that deforms to impede flow in a failure of the container wall. In some embodiments, the multi-sheet layer includes cavities formed between individual sheets.

A safety system for an automobile includes a safety device with containing areas in which two premixed liquids are stored during an initial state and which are in fluid communication with a fuel tank. Two valves are mounted internally in the safety device and are closed in the initial state to separate the premixed liquids. The valves are spaced apart at an initial distance, in the initial state, that is greater than a triggered distance, in a triggered state. A cylindrical ring is mounted in the safety device near the valves and has evacuation holes around its periphery that are adjacent to a respective pair of flow-mix channels. The flow-mix channels form a flow-path between the containing areas and a respective evacuation hole via which, in the triggered state, the premixed liquids are combined into a mixed liquid that is subsequently expelled for neutralizing fuel flammability in the fuel tank.

A method and system for forming a self-sealing volume includes an elastomeric composite structure. The structure includes layers of a cast polyurethane derived from a neat polyurethane monomer reaction mixture that does not substantially react at room temperature. The polyurethane monomer reaction layer includes a reaction product of an organic polyisocyanate and a reactive hydrogen-containing material reacted with a mixture of a monomeric polyol and polymeric polyols. The structure may further include one or more layers of a fabric that have been precoated with an aliphatic polyurethane, and one or more sealing layers. A fuel impermeable inner liner may be positioned in an inner region. The sealing layers may comprise at least one of partially vulcanized natural rubber (NR), polyisoprene (IR), styrene butadiene (SBR), or a blend of SBR with NR or IR. A dimensionally correct, self-sealing volume may be created by inflating the volume during its cure.

An explosion suppression insert for a fuel tank includes a hollow body having an inner surface and an outer surface, the hollow body being made of an explosion suppressing material; and a plurality of perforations defined in the outer wall. In some embodiments, a nonwoven explosion resisting insert for a fuel tank includes a body including a plurality of interconnected non-woven fibrous struts being made of an explosion suppressing material, the body having a first end and a second end; and a plurality of voids defined by the plurality of struts, the voids being configured such that the body has a porosity of between 5 pores per inch and 50 pores per inch. Methods of manufacturing explosion resisting inserts are also provided.

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 vehicle includes a plurality of tanks storing gas in the tanks and arranged in a longitudinal direction of the vehicle, and each of the tanks includes: a pressure relief device configured to open when a temperature of the tank becomes a predetermined temperature or more; and a release part releasing the gas in the tank in a predetermined direction by the opening of the pressure relief device, wherein the release direction of the gas released from the release part of the front tank located at a frontward position among the plurality of tanks is defined to be a direction directly facing a space between the pressure relief devices of the rear tanks disposed more rearward than the front tank, and a ground.

A transport refrigeration system having: a refrigerated cargo space (119); a refrigeration unit (22) in operative association with the refrigerated cargo space, the refrigeration unit providing conditioned air to the refrigerated cargo space; a first engine (150) configured to power the vehicle; a second engine (26) configured to power the refrigeration unit; a first plurality of fuel tanks (350) fluidly connected to first engine, the first plurality of fuel tanks configured to supply fuel to the first engine; a second plurality of fuel tanks (330) fluidly connected to second engine, the second plurality of fuel tanks configured to supply fuel to the second engine; and a single filling point (310) fluidly connected to the first plurality of fuel tanks and second plurality of fuel tanks. The single filling point (310) is configured to receive fuel.
