The invention provides systems and methods for mounting a fuel system to a vehicle. In some embodiments, the invention provides systems and methods for mounting a fuel system comprising a fuel tank to a vehicle chassis using a bracket, which may be a multi-part bracket, and may be referred to as a “drop and go” bracket.

A vehicle is provided with an interior chamber apart from a passenger compartment, and a container chamber in which a high pressure gas container is accommodated. A heat generating body is accommodated in the interior chamber. Further, in the vehicle, there are formed introduction ports through which atmospheric air is introduced into the interior chamber, a communication passage that enables communication between the interior chamber and the container chamber, and a lead-out port through which the atmospheric air is led out from the container chamber. The atmospheric air that is introduced into the interior chamber through the introduction ports flows into the container chamber via the communication passage, and furthermore, is led out to the exterior of the container chamber from the lead-out port.

An apparatus and a method are provided for an alternative fuel system, comprising a plurality of fuel tank assemblies interconnected with fuel lines; the plurality of fuel tank assemblies comprising a CNG fuel tank and a fuel tank shield; wherein a first and second fuel tank assembly is disposed immediately in front of a rear wheel assembly, and a third fuel tank assembly is disposed immediately behind the rear wheel assembly.

An improved fuel tank is disclosed that includes a plurality of recessed ribs formed in the fuel tank adjacent a fuel filter. The fuel filter is received in a pocket formed in the lateral side of the fuel tank by a front side wall and rear side wall that extend from the lateral side to a recessed wall. The ribs include an inner portion, a transverse portion and an outer portion. The recessed ribs have upper and lower walls that converge toward a base wall.

A high-pressure hydrogen container is provided that has a simple configuration, requiring less labor for manufacture, achieving reduced manufacturing costs, and ensuring pressure resistance. The high-pressure hydrogen container includes a metal cylinder configured to store high-pressure hydrogen, a pair of lid parts configured to cover both end portions of the metal cylinder, and a plurality of fastening parts configured to fix the pair of lid parts in a state where the metal cylinder is clamped between the pair of lid parts.

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 work vehicle includes a front wheel, a rear wheel, a liquid tank, a front-wheel fender, a rear-wheel fender, a floor portion, and an electric-component room. The front wheel, the rear wheel, and the liquid tank are supported by a vehicle body. The front-wheel fender is disposed to surround a portion around the front wheel. The rear-wheel fender is disposed to surround a portion around the rear wheel. The floor portion is provided between a lower end portion of the front-wheel fender and a lower end portion of the rear-wheel fender. The electric-component room is provided on an upper surface of the floor portion, and houses electric components in a space formed with the floor portion. The electric-component room is disposed at an outer side of the liquid tank in a vehicle width direction of the vehicle body.

A fuel system is provided that includes a fuel system frame and in some cases access steps. The frame can be mounted to a vehicle frame rail. Bracket assemblies can be coupled to the fuel system frame at a plurality of positions. The fuel tank can be mounted at neck portions thereof and can be supported on the frame rail between the neck portions, e.g., spaced a distance from the neck portions in a longitudinal direction of the fuel system. The access steps can be non-rectangular to provide a wide stepping portion even if the fuel system includes large tanks. The steps can be directly supported by an outside surface of the tank.

Some of the present apparatuses include a frame defining first and second supports and at least a portion of a rigid tank mount laterally offset from the first and second supports, where the first support is configured to be pivotally coupled to a vehicle such that the frame is movable relative to the vehicle between a first position in which the second support is spaced apart from the vehicle and second position in which the second support is coupled to the vehicle. Some apparatuses include a frame mount having a flange defining a bounded opening configured to receive a fastener and a post extending from the flange and away from the opening, where the first support is configured to be pivotally coupled to the flange via the fastener and the second support is configured to be coupled to the post when the frame is in the second position.

A structurally integrated fuel tank and method of assembling is disclosed. The fuel tank may comprise a body and a neck disposed on the body. The neck may be configured to be coupled to an arm of a front frame of a machine. The body may comprise a cover, an endwall and a base. The cover includes a cover hitch that defines an upper pivot bore centered about a pivot axis. The upper pivot bore is configured to receive a pivot fastener about which the fuel tank is pivotable. The endwall may be disposed below and coupled to the cover. The base may be coupled to the endwall, and may include a lower hitch that extends outward and away from the endwall. The neck and the body together define a chamber configured to store fuel. The cover is a top of such chamber.
