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 portion, 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.

A fuel tank having one or more support domes configured to engage with, and assist in positioning, a fuel tank insert.

A first gap to be eliminated at the time of a compressive deformation of a fuel-tank main body is formed between a lower-side reinforcing member and an upper-side reinforcing member in a fuel-tank main body. A second gap to be eliminated at the time of an expansion deformation of the fuel-tank main body is formed between an opposed member of the lower-side reinforcing member and the upper-side reinforcing member.

The present invention relates to a flange that includes a base region, a first raised region, a second raised region, a first sloped region between the base region and the first raised region, and a second sloped region between the base region and the second raised regions, wherein the first and second sloped regions extend through a gap region between the first and second raised regions, and wherein the first and second sloped regions define multiple concave and convex regions in multiple planes of the flange so as to reduce stress within the flange.

The present invention relates to a plastic tank which provides storing of gasoline and urea liquid called adblue, used in automotive industry, particularly in vehicles which operate with gasoline and which reduces the damage of vehicles, which operate with gasoline, to the environment, in a single tank with two chambers, and relates to a special core heating system designed for production of this tank by using rotation technology.

The present disclosure relates to an apparatus for fixing a pressure vessel, the apparatus including: a frame part disposed separably from a subject and configured to support a pressure vessel; and a lifting device configured to selectively raise or lower the frame part relative to the subject, thereby facilitating a process of replacing the pressure vessel.

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.

The present invention relates to an integrated anti-siphon fuel filler neck assembly that includes wedge shaped apertures and a side wall that includes side wall apertures connected to the wedge shaped apertures, wherein the wedge shaped apertures and the side wall apertures are sized to prevent a siphon hose from passing there through.

A stiffness reinforcement structure for a fuel tank of a vehicle includes: a reinforcing column having an upper opening and a lower opening, and side openings arranged at both sides of an upper end and both sides of a lower end thereof; sliders fastened to the side openings of the reinforcing column; an upper thermal bonding member inserted in the upper opening and fastened to corresponding sliders; a lower thermal bonding member inserted in the lower opening of the reinforcing column and fastened to corresponding sliders with a bottom thermally bonded to an inner side of the fuel tank; and springs wound around outer sides of the reinforcing column and the sliders and providing elastic compression force to the upper thermal bonding member and the lower thermal bonding member.

The present invention relates to a curve-combined square pressure tank with which curves are combined so as to maintain internal high pressure, improve space efficiency, and reduce the weight thereof, and to a pressure tank, in which planes and curves are combined, formed by connecting flat plate members and curved members, having a plurality of aligned tension members for connecting the flat plate members facing each other, and having stress buffer parts formed at connection parts of the flat plate members and the curved members so as to enable internal pressure to be maintained.
