A fuel tank inerting system includes an air separation module with an oxygen permeable membrane and a variable vacuum source in fluid communication with the air separation module. The variable vacuum source provides an adjustable vacuum to the permeate side of the oxygen permeable membrane in the air separation module, driving production of inert gas for fuel tank inerting or fire suppression.

A pressure vessel stores fuel. The pressure vessel includes a liner, a fiber-reinforced layer, at least one end piece, and at least one outlet. The fiber-reinforced layer surrounds the liner, at least in some regions. The end piece is covered by the fiber-reinforced layer, at least in some regions. The at least one outlet is used to carry fuel that has collected in a boundary layer between the liner and the fiber-reinforced layer and is to be drained. The outlet surrounds the end piece, at least in some sections. The outlet is arranged and formed in such a way that the fuel to be drained escapes from the boundary layer into the outlet.

A fuel tank in a vehicle. The fuel tank includes a protective outer shell, an inner shell and a crush sleeve. The protective outer shell defines an outer tank. The inner shell defines an inner tank which holds fuel. The inner shell is housed in the outer shell and is isolated from the outer shell by a space. The crush sleeve is provided in the space between the outer shell and the inner shell. The crush sleeve supports the inner shell and maintains the inner shell in position relative to the outer shell. Wherein during an impact to the vehicle, the force of the impact causes the outer shell and the crush sleeve to deform and the inner shell to move relative to the outer shell.

An apparatus for controlling an engine start during refueling of a hybrid vehicle includes a controller configured to: stop an engine to block the engine start by sensing whether the vehicle enters into a refueling state in accordance with a fuel injection port open or closed state, a vehicle speed, and brake pedal state (BPS) information, and start the engine to release blocking of the engine start in accordance with a switchover to a hybrid electric vehicle (HEV) mode by sensing whether the refueling state has been released in accordance with the fuel injection port open or closed state, the vehicle speed, and acceleration pedal state APS) information.

A transport refrigeration system (200) including: a first engine (26) configured to power a refrigeration unit (22); a first fuel tank (330) fluidly connected to the first engine (26) through a first fuel line (332); a first shut off valve (450) located within the first fuel line (332) proximate the first fuel tank (330); a second shut off valve (72) located within the first fuel line (332) proximate the first engine (26); a sensor system (80) configured to detect at least one of a crash of the transport refrigeration system (200), a crash of the first fuel tank (330), a fuel leak in the first fuel line (332), and an engine stall in the first engine (26); and a controller (30) configured to close the first shutoff valve (450) and second shutoff valve (72) when at least one of a crash of the transport refrigeration system (200), a crash of the first fuel tank (330), a fuel leak in the first fuel line (332), and an engine stall in first engine (26) is detected.

Various techniques are provided for an expandable energy absorbing fluid bladder. In one example, the fluid bladder includes a primary portion and a secondary portion. The secondary portion can be configured to expand or increase in volume when the fluid bladder is subjected to a pulse greater than a threshold pulse. Expansion of the secondary portion can allow fluid or additional fluid to flow into the secondary portion and thus decrease a peak pulse and, thus, avoid rupture of the fluid bladder.

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 one 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.

A fuel gas tank arrangement in a vehicle. The fuel gas tank arrangement comprises a fuel gas tank for holding a pressurized fuel gas volume, and a valve configured to ventilate fuel gas from the fuel gas tank into ambient surroundings. The valve comprises a controllable valve actuator communicatively connected to a control unit. The valve actuator is configured to open the valve to a determined opening degree for controlling a flow rate of ventilated fuel gas. The disclosure also relates to method for safety ventilation of fuel gas from a fuel gas tank arrangement.

Fluid containers to evacuate spilled fluid from the interior of an enclosure of the fluid container are disclosed. An example system includes an enclosure and a fluid container within the enclosure. The fluid container includes a fluid capture area at a top of the fluid container and a channel at a side of the fluid container. The fluid capture area directs the fluid to the channel, and the channel directs the fluid from an interior of the enclosure to an exterior of the enclosure.

A fuel tank in a vehicle. The fuel tank includes a protective outer shell, an inner shell and a crush sleeve. The protective outer shell defines an outer tank. The inner shell defines an inner tank which holds fuel. The inner shell is housed in the outer shell and is isolated from the outer shell by a space. The crush sleeve is provided in the space between the outer shell and the inner shell. The crush sleeve supports the inner shell and maintains the inner shell in position relative to the outer shell. Wherein during an impact to the vehicle, the force of the impact causes the outer shell and the crush sleeve to deform and the inner shell to move relative to the outer shell.
