A display device also includes an available amount-of-fuel calculator for calculating an available amount of fuel, an average mileage calculator for calculating an average mileage from a consumed amount of fuel and a vehicle's traveled distance, an available travel distance calculator for calculating an available travel distance from the available amount of fuel and the average mileage, and a display unit for displaying the available travel distance. The available amount-of-fuel calculator uses a learned value based on outputs as a corrective value for correcting the output of a second sensor when the calculation of the available amount of fuel switches from being based on the output of the second sensor to being based on the output of a first sensor.

A work vehicle including a drive device (10) having an internal combustion engine (12) for driving a vehicle body (1) has: a first tank (32) that is disposed in front of or behind the drive device, and stores fuel (9) to be supplied to the internal combustion engine; a second tank (34) that is disposed below the drive device so as to be separated from the first tank by a predetermined distance, and stores the fuel to be supplied to the internal combustion engine; a first storage amount detection part (70) that is disposed in the first tank, and detects an amount of the fuel stored in the first tank; and a second storage amount detection part (80) that is disposed in the second tank, and detects an amount of the fuel stored in the second tank.

A fuel storage assembly includes a power source, a first tank, a fuel pump, an electric relay, a second tank, and a shut-off device. The fuel pump is adapted to remove fuel from the first tank. The electric relay is electrically connected between the power source and the fuel pump for terminating electric power to the fuel pump. The second tank is adapted to receive the fuel removed from the first tank. The shut-off device is located in the second tank and is electrically connected to the electric relay, and is configured to detect a shut-off level of fuel in the second tank. Upon detection of the shut-off level, the shut-off device effects shut-down of the fuel pump via the electric relay.

Estimating fluid related quantities of a first fluid compartment and a second fluid compartment disposed in or connected to a moveable platform. Measurements from the first fluid level sensor, the second fluid level sensor, the third fluid level sensor, the fourth fluid level sensor are combined into a unified calculation. The fluid related quantities are calculated from the unified calculation, the fluid related quantities comprising all of: (1) a fluid orientation estimate which is common to both the first fluid compartment and the second fluid compartment, (2) a first fluid height estimate for the first fluid compartment, and (3) a second fluid height estimate for the second fluid compartment, whereby (1), (2), and (3) form a set of results.

The present disclosure relates to a valve assembly adapted to be located at least partially in a body of fluid for controlling fluid flow from the body of fluid to a fluid outlet port. The valve assembly has an extension in a first direction and includes a fluid inlet port having an extension at least partially in the first direction. The valve assembly further includes a valve member being movable in the first direction relative to the fluid inlet port between an open position, in which the fluid inlet port is adapted to provide a fluid communication between the body of fluid and the fluid outlet port, and a closed position, in which the valve member covers the fluid inlet port such that fluid communication between the body of fluid and the fluid outlet port via the fluid inlet port is prevented.

A built-in support pillar for a fuel tank including: a support pillar main body that is configured to be disposed inside a box-shaped fuel tank, and that joins together mutually facing internal walls of the fuel tank; an engaging portion for positioning that is formed on an outer circumferential surface of the support pillar main body; and a bracket that is mounted on the support pillar main body, the bracket including an engaged portion configured to be engaged with the engaging portion, and a fixing portion to which a built-in component is fixed.

A fuel tank includes a fuel tank main body portion, a first supporting pillar portion, and a second supporting pillar portion. The first supporting pillar portion is provided at a vehicle rear side of an inner side of the fuel tank main body portion. The second supporting pillar portion is provided at a vehicle front side of the first supporting pillar portion at the inner side of the fuel tank main body portion and is longer in the vehicle vertical direction than the first supporting pillar portion is in the vehicle vertical direction.

A fuel supply system for a road vehicle and having: a fuel tank, which is shaped like saddle due to the presence of a central saddle and delimits an inner volume divided into an upper area, which is located above the central saddle, and two lower areas, which are located under the upper area and are separated from one another by the central saddle; two low-pressure fuel pumps, which each suck from the bottom of a corresponding lower area; at least one high-pressure fuel pump, which receives fuel from both low-pressure fuel pumps; a level sensor arranged in the upper area and configured to measure a fuel level only in the upper area; and two level sensors, each arranged in a respective lower area and configured to measure a fuel level only in the respective lower area.

A fuel storage assembly includes a power source, a first tank, a fuel pump, an electric relay, a second tank, and a shut-off device. The fuel pump is adapted to remove fuel from the first tank. The electric relay is electrically connected between the power source and the fuel pump for terminating electric power to the fuel pump. The second tank is adapted to receive the fuel removed from the first tank. The shut-off device is located in the second tank and is electrically connected to the electric relay, and is configured to detect a shut-off level of fuel in the second tank. Upon detection of the shut-off level, the shut-off device effects shut-down of the fuel pump via the electric relay.

Methods and systems are provided for a fuel tank mounted to a vehicle. Specifically, a saddle fuel tank comprising of a primary and secondary fuel compartment, each compartment having a module for mounting a fuel pump, fuel sensor and other accessories is disclosed. A first and second crimped opening formed on a top external wall and bottom internal wall, respectively of the saddle fuel tank may provide means for securely mounting a main and sub-side module to the fuel tank.
