Description:TECHNICAL FIELD
[0001] The present subject matter relates to a fuel tank assembly for a vehicle. More particularly, the present invention relates to a fuel tank assembly and the location of fuel sensors in a vehicle.

BACKGROUND
[0002] A vehicle generally consists of a chassis fixed on two or more rolling wheels, where at least one wheel is driven by a engine. The engine can be an internal combustion engine, or an electric motor. An internal combustion engine consists of a carbon-based fuel being burned in a combustion chamber under high pressure. The force being generated by the combustion drives a piston, which in turn drives a crankshaft, which is then transferred to the driven wheel. A lot of heat is generated in this process, and while some of it is converted into rotational motion of the crankshaft, a lot of the energy generated escapes from the combustion chamber, increasing the temperature of the engine, and especially the combustion chamber.
[0003] The common carbon-based fuels used in road vehicles are petrol and diesel. Other vehicles, such as aircrafts or sea vessels, may use other kind of carbon based fuels as well. Since the fuel is in liquid form, the fuel has to be stored in a sealed container so that the fuel is not lost or evaporated during the motion of the vehicle. Also, since the fuel is highly combustible, it needs to be protected from any source of heat in close proximity. One such source of heat is the engine.
[0004] Fuel is stored in fuel tank. The fuel tank is generally disposed above the engine. This is because fuel can either be pumped into the engine from the fuel tank using a fuel pump, or it can be fed into the engine by using gravity. The riders’ seat is usually disposed directly behind the fuel tank. This gives better ergonomics for the rider.
[0005] Sometimes, overfuelling can be dangerous. Thus, amount of fuel present in the fuel tank needs to be displayed to the rider. In some conventional designs, fuel level detector mechanisms are present. However, these mechanisms have their own drawbacks such as it gives inaccurate value while uphill and downhill riding of the vehicle.
[0006] Another drawback can be if the sensor is positioned in the vicinity of the center of gravity of the body, space for the other components is reduced, requiring volumes of the other components to be smaller or have intricate shapes. Generally, tilting of the vehicle occurs infrequently, and therefore the tilting sensor is activated infrequently. For these reasons, it is undesirable for the tilting sensor to occupy the space in the vicinity of the center of gravity of the body. In addition, brackets and electric wire are needed to mount the tilting sensor in the vehicle, increasing structural members, the number of components, and the overall manufacturing cost of the vehicle.
[0007] Thus, it is important to have a fuel tank assembly which can overcome the above-mentioned problems.
[0008] It is an object of the present invention to measure the entire volume of the fuel tank accurately.
[0009] It is an object of the present invention to make customer aware of the amount of critical fuel level. Critical fuel level is the minimum amount of fuel which is necessary to start the vehicle. Thus, it is important to make the user aware of the critical fuel level else he/she may face problems during the ride if fuel gets exhausted.
[00010] It is an object of the present invention to avoid over fuelling in the vehicle.
[00011] It is an object of the present invention to avoid noise and vibration due to mechanical parts.
[00012] It is an object of the present invention to reduce the overall weight and cost of the vehicle.
[00013] It is an object of the present invention to measure the fuel in the bottom of the tank.
