A multi-lobe seal for a sealing device for sealing an opening in a multi-layer wall of a fuel tank, the multi-layer wall having a layer of fuel barrier material and an opening in the multi-layer wall, the multi-lobe seal being fuel-impermeable and capable of being positioned in contact, at the opening in the multi-layer wall of the fuel tank, between the layer of fuel barrier material of the multi-layer wall of the fuel tank and a component, is disclosed. The multi-lobe seal includes, on the face capable of being in contact with the layer of fuel barrier material of the multi-layer wall, at least two protrusions, one of which leans on the layer of fuel barrier material of the multi-layer wall.

A fuel tank includes a built-in component having a head portion, a neck portion, and a shoulder portion, the built-in component being anchored to a tank body by blowing air from outside a parison to cause the parison wrap around the neck portion during molding of the tank body. A slit extending in one direction only is formed on a surface of the shoulder portion as an air vent path.

The fuel storage system includes a fuel tank fill assembly and a fuel tank. The fuel tank fill assembly is configured to conduct fuel to the fuel tank from a fuel-dispensing nozzle and may include corrosion-resistant components. The fuel tank stores the fuel for later use by an engine included in the vehicle.

A combined cooling and water braking system for a vehicle comprises a first water recirculation loop having a first heat exchanger configured to cool water flowing in the first water recirculation loop, the first water recirculation loop comprising a water conduit for transporting heat away from a propulsion device configured to generate a propulsion power for the vehicle. A second water recirculation loop having a second heat exchanger is configured to cool water flowing in the second water recirculation loop. A retarder is configured to be coupled to a pair of wheels of the vehicle. The second water recirculation loop may be selectively used for cooling the propulsion device and for providing water to the retarder for water braking. There is also provided a method for cooling a propulsion device of a vehicle and water braking a pair of wheels of a vehicle.

Provided is a roll over fuel-vapor valve is provided including a housing defining a valve having a valve inlet port extending through a wall of the housing and a valve outlet port and a float member disposed between the inlet port and the outlet port and being displaceable between an open position and a closed position the hosing further comprising a fluid flow channel extending along a top portion thereof and having a first end and a second end, wherein the outlet port extending into the channel such that in the open position fluid flow is facilitated between the valve inlet port and the channel.

A bodywork support structure for a vehicle includes two side sills that are spaced apart in a transverse direction where the two side sills have a reinforcing element that is disposed in a hollow space. A floor is disposed between the two side sills and connected to the two side sills and an energy store for storing electrical energy and/or a fuel for powering the vehicle is disposed under the floor. The reinforcing element is formed as a corner reinforcement disposed in a corner area where the corner reinforcement has a first connection area that is attached to an external wall, a second connection area that is attached to a lower flange, and a wall area that connects the first and second connection areas with each other across the corner. An open space is formed between the corner reinforcement and an internal wall in the transverse direction of the vehicle.

A method for determining a filling stop during a filling process of an operating fluid container whose operating fluid container interior can be filled with an operating fluid via a filling pipe opening into said interior, wherein a pressure sensor for determining a pressure within the filling pipe is arranged in the filling pipe, wherein the method has the following method steps: acquiring the time profile of pressure values acquired by means of the pressure sensor; and outputting a filling stop signal in accordance with the time profile of the pressure values. In addition, the present invention discloses an operating fluid container system having an operating fluid container and a filling pipe, opening into an operating fluid container interior, for filling the operating fluid container with an operating fluid, wherein the operating fluid container system has a pressure sensor arranged within the filling pipe and is coupled via a data line to an electronic control device for transmitting data, representing the pressure within the filling pipe, to the electronic control device, wherein the control device is designed to carry out the method according to the invention for determining a filling stop.
