A diesel fuel and DEF combination tank provides a supplemental storage of diesel fuel and DEF for a vehicle. In particular, the combination tank comprises a first compartment for diesel fuel and a second compartment for DEF. Each compartment is provided with a respective outlet port for dispensing the fuel from the combination tank. Dispensing of fluid to the vehicle's fuel system is conducted by gravity feed or alternatively by pumping.

An apparatus and a method are provided for a compressed natural gas fuel system configured to replace a motor vehicle's fuel system comprising a storage assembly comprising an enclosure, wherein the enclosure contains a plurality of tanks configured to contain compressed natural gas; and a chassis disposed within the enclosure and configured to retain the plurality of tanks, wherein the storage assembly is configured to be mounted to the roof of a motor vehicle.

A motor vehicle has a pressure vessel unit, the pressure vessels of which are arranged on both sides of a recess or depression in a passenger compartment floor.

The invention relates to a filler neck (1) for an auxiliary liquid reservoir for a motor vehicle, in particular for a urea reservoir, having a neck housing (9), which defines a mouth hole stub (10) for a filler nozzle (7) and a filling channel (11) leading into the reservoir, wherein a receiving structure for a filler nozzle (7) is provided within the neck housing (9). At least one venting path, which is of enlarged cross section, at least in a section or sections, and of chamber-like or labyrinth-like design, is formed within the neck housing (9), allowing a venting flow parallel and counter to the refilling volume to flow through the neck housing (9) during refilling.

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.

A refuse vehicle includes a chassis having a prime mover, a body assembly coupled to the chassis, a tailgate pivotally coupled to the body assembly, an energy storage device coupled to the tailgate and moveable therewith, 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 including at least one frame member positioned to direct impact loads around the energy storage device. The prime mover is configured to be powered by the energy storage device. The impact mitigation system provides a protected region within which the energy storage device is disposed.

An enclosed volume is provided for performing operations in space, or on any astronomical object, in a manner separated from aspects of the external environment. The enclosed volume can be a flexible container for a satellite. The enclosed volume can include a membrane having a fluid barrier layer and being configured to contain a propellant gas or fluid; and an expulsion device configured to expel material from the membrane. In a stowed configuration, the flexible container is contained within the satellite, and in a deployed configuration, the flexible container extends away from the satellite. The flexible container can inflate from one shape, in the undeployed configuration, to another shape, in a deployed configuration. The other shape can be toroidal or other appropriate shapes. The flexible container can provide bipropellant, blowdown, and gas/fluid metering functionality. Entertainment and game play can be enabled by the enclosed volume involving robots and other devices.

A fuel-mixing prevention filler neck device is provided. The fuel-mixing prevention filler neck device includes a fuel dispensing gun insertion unit that receives a fuel dispensing thereinto and a coupling unit that provides fluid communication with a bottom of the fuel dispensing gun insertion unit. The coupling unit is disposed on an exterior circumferential surface thereof with coupling protrusions for fastening with a plurality of slots formed in a filler pipe. Further, a first side of a lower portion of the coupling unit is open to form a coupling region. A misfueling prevention unit slidably moves to the coupling region to be coupled to the coupling unit. Additionally, the misfueling prevention unit is closed when a gasoline fuel dispensing gun is inserted and being opened when a diesel fuel dispensing gun is inserted.

A fluid system for a vehicle is provided. The fluid system is configured to couple to a chassis of the vehicle. A frame assembly of the fluid system is configured to couple with the chassis directly or with another component that is coupled, directly or indirectly, with the chassis. A cowling of the fluid system can enclose a fuel pressure vessel and an auxiliary fluid vessel. The auxiliary fluid vessel is configured to be placed in fluid communication with the component powered or operated by the fluid therein.

A mounting assembly for supporting a fuel supply on a vehicle, which is specifically adapted for the operable support and positioning of an auxiliary fuel supply. The vehicle with which the mounting assembly is utilized may vary significantly, but is primarily structured for use on mine haul vehicles, bulldozers, and other heavy duty commercial vehicles, wherein the operation thereof is significantly benefited or enhanced through the provision of an auxiliary, or alternate fuel supply such as, but not limited to, liquid natural gas (LNG), selectively powering the engine of the vehicle as determined by an improved electronic control system. The mounting assembly comprises a containment structure in the form of at least one fuel tank and a housing is structured to enclose the fuel tank. A base supports the housing and provides a pivot point about which the housing may be disposed between a first and second orientation.
