A fuel supply device includes: a sub-tank to be fixed on a bottom of a fuel tank, the sub-tank temporarily storing fuel in the fuel tank, an upper side of the sub-tank having an opening; a bracket attached to an opening side of the sub-tank; an electric pump that pumps up the fuel in the sub-tank and supplies the fuel to outside of the sub-tank; and multiple fitting portions arranged on an outer edge of the bracket and to fix the bracket to the sub-tank by being fitted to a plurality of receiving portions arranged on the opening of the sub-tank.

The present invention provides systems and methods for preventing fire outbreak and suppressing fire in liquid-fuel activated vehicles.

Intake arrangement for an internal combustion engine for the intake of a liquid medium from a container, having a strainer, via which liquid medium can be taken in from the container, and having at least one suction pipe which opens with a first end into the strainer and via which the liquid medium can be delivered towards a suction pump, which interacts with the respective suction pipe. The suction pipe is mounted at a second end that faces away from the strainer such that it can be pivoted about an axis such that the suction pipe follows a movement of the liquid within the container.

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 container assembly for a motor vehicle comprises a first container (20) for a fuel for the motor vehicle and a second container (10) for a liquid auxiliary agent, in particular for the reducing agent solution of an SCR catalyst. The second container (10) is integrated into the first container (20). A bottom-mounted removal device having at least one pump (11) for removing the auxiliary agent is provided in the second container (10).

A combined fluid tank used in diesel engine vehicles using AdBlue is provided, wherein the AdBlue is a urea-based chemical and the combined fluid tank is manufactured using a rotation technology from a polymer-based material. The combined fluid tank includes a first chamber for diesel and a second chamber for AdBlue positioned next to the first chamber, a double-walled impermeable chamber constructed between the first chamber and the second chamber, and a baffle located in at least one of the first chamber and the second chamber and the baffle provides sound and vibration damping, and to a production method of the combined fluid tank.

A fuel tank for a vehicle, having a plurality of chambers, the chambers fluidly connected to allow a flow of fuel between the chambers, where at least one of the chambers has a flexible fluid container contained within an expandable rigid outer shell.

A valve system of a fuel system for a vehicle may close a jet pump-side flow path when a pressure of fuel supplied from a fuel pump to an engine is lower than a prescribed fuel pressure at engine start-up, and open the jet pump-side flow path when the pressure of fuel is equal to or higher than the prescribed fuel pressure at the engine start-up, thereby improving cold startability of an engine, and may also allow the jet pump-side flow path to be kept in an opened state between a low load region and a high load region of the engine after the engine start-up, thereby smoothly keeping a function of the jet pump after the engine start-up.

suction system for a liquid reservoir (3) it is provided, the reservoir being defined by side walls and a bottom wall (30), the system comprising one layer of permeable material (2), and the system it is characterized in that it comprises fastening means (21) for fixing said permeable layer (2) onto at least one wall (30) of said reservoir (3); suction means (1, 10, 16, 17) of said liquid arranged within said permeable layer (2); and connecting means (14, 41, 42) of said suction means (1, 10, 16, 17) to a suction duct for sucking said liquid; the arrangement being such that an internal volume (23) it is defined between said one layer of permeable material (2), said fastening means (21), and said at least one wall of said reservoir (30), wherein the liquid it is sucked into said internal volume (23) through said layer of permeable material (2) and through said suction means (1, 10, 16, 17).

A fuel tank for a vehicle includes a main tank comprising a first tank volume defined by an outside wall and an auxiliary tank extending from an aperture provided in the outside wall. The auxiliary tank is formed as a pocket-shaped continuation of the outside wall into the first tank volume bounded by the outside wall. The auxiliary tank forms a second tank volume which is separated from the first tank volume and opens into a filler neck which runs inside the first tank volume and emerges on the outside wall of the main tank.
