A method for producing a compressed gas tank for a motor vehicle includes inserting a bundle of heat-conducting elements through an opening in a housing of the compressed gas tank and exerting a force on the bundle that radially expands the bundle within the housing beyond the size of the opening. The heat-conducting elements may be helically wound about a central axis when inserted through the opening with a torsional force applied to unwind the elements while radially expanding and reducing axial length of the bundle. A compressed gas tank for a motor vehicle includes a plurality of heat-conducting elements including at least one tube within a tank housing that extend axially along the tank and radially within the housing to a size exceeding an opening of the housing. The tube is configured to circulate coolant to cool compressed gas within the tank.

A work vehicle in which hoses and the like are easy to handle and adequate routing of these hoses is possible. The work vehicle includes a traveling body which includes: traveling devices; and a connecting section which is configured to connect a working machine to the traveling body. The traveling body includes: a pair of left and right body frames which extends longitudinally; an engine which is mounted on the body frames and works as a driving source of the traveling devices and the working machine; a base plate which is provided on the body frames; a cooler which is provided on the base plate; and hoses which are connected to the cooler and routed, the base plate has a hose insertion hole into which the hoses are inserted, and the hoses pass through the hose insertion hole, extend below the base plate, and are routed toward the engine.

Filling methods and systems are provided for a conformable fuel tank. In one example, a system comprises an active thermal management arrangement for the conformable fuel tank. The active thermal management arrangement comprises one or more recirculation passage for mixing hot fuel distal to an inlet port of the conformable fuel tank with cool incoming fuel flowing to the inlet port.

The present invention relates to an integrated fuel tank assembly, and a process of manufacturing the same, for use in commercial vehicles, and more particularly, to an integrated fuel tank assembly that allows multiple components to be manufactured as a single integral structure, such as a single extruded device including a draw tube, a return tube, a fuel sender device, and a vent, for example.

A fuel supply system for supplying a fuel from a fuel tank to an engine includes a fuel pump for delivering a fuel from the fuel tank, a fuel pipe for flowing therethrough the fuel from fuel pump, a canister including an activated carbon capable of adsorbing and desorbing vaporized fuel generated in the fuel tank, a heat exchanging mechanism for performing heat exchange between the fuel pipe and the canister on a downstream side of the fuel pump, and a return pipe for returning the fuel from the fuel pipe to the fuel tank on a downstream side of the heat exchanging mechanism.

To make a reserve tank be hardly affected by the heat of an engine. An engine room (5) is totally covered by an exterior cover (9) including openings (44) at the upper surface, and includes in the inside thereof an engine (13), a radiator (24), a cooling fan (20) for sucking external air and cooling the radiator, and a reserve tank (30) for storing cooling water of the engine. The reserve tank (30) is disposed at a position above the engine (13) and facing the openings (44) and a position on the upstream side of the flow of the air with respect to the openings (44).

A vehicular propulsion system, a vehicular fuel system and a method of operating an internal combustion engine. A separation unit that makes up a part of the fuel system includes one or more adsorbent-based chambers such that the separation unit may selectively receive and separate at least a portion of onboard fuel into octane-enhanced and cetane-enhanced fuel components. A supply tank includes three compartments where the first contains the onboard fuel, the second receives a vaporized adsorbate from the separation unit and condenses at least a part of it into one of an octane-rich fuel component or a cetane-rich fuel component, while the third may either store the condensed and enriched fuel component or help condense more of the vaporized adsorbate. The condensing takes place through heat exchange between the onboard fuel and the vaporized adsorbate that are present within the various compartments of the supply tank. A controller may be used to determine a particular operational condition of the internal combustion engine such that the onboard fuel can be sent to one or more combustion chambers within the internal combustion engine without first passing through the separation unit, or instead to the separation unit in situations where the internal combustion engine may require an octane-rich or cetane-rich mixture.

A fuel cell vehicle comprising: a hydrogen tank which is mounted on the vehicle so as to have a center axis generally parallel to a front/rear direction of the vehicle; a high-voltage electric component which is positioned either forward or rearward of the hydrogen tank and which operates on high voltage; an aftercooler placed between the hydrogen tank and the high-voltage electric component to cool compressed air; and a fuel cell stack which is supplied with the cooled compressed air.
