Description:A FUEL TANK FOR A VEHICLE
FIELD OF INVENTION:
[001] The present subject matter described herein, relates to a vehicle construction and more particularly, relates to a fuel tank.

BACKGROUND AND PRIOR ART:
[002] It is known to provide a fuel tank for a vehicle to hold fuel to be used by an engine of the vehicle. Modern fuel delivery systems for automotive vehicles with engines having fuel injectors have utilized an electrically driven fuel pump in the vehicle main fuel tank. Typically, the electric fuel pump mounted in the vehicle tank is having a secondary fuel space or is mounted within a reservoir received in the tank.
[003] The reservoir supplies fuel to the pump in the event there is an interruption in the availability of fuel from the tank, such as when, under low fuel level conditions, cornering of the vehicle causes sloshing or movement of the fuel away from the pump inlet and to one side or the other of the tank, and/or when the tank is excessively tilted by vehicle inclination on severe grades, or when essentially all of the fuel in the main tank has been consumed or used. Such situations are undesirable as these interrupts a normal running condition of the vehicle due to improper fuel suction by the fuel pump, and improper fuel supply to the engine. For example, stopping of the vehicle, unwanted jerks, etc. may occur during improper fuel supply.
[004] Korean Patent publication KR101428208B1 relates to a fuel tank for a vehicle. More specifically, the fuel tank for a vehicle ensures the continuous suction operation of a fuel pump by integrating adjacent partition walls to the surface with the fuel pump of the fuel tank mounted on. Accordingly, the present invention integrally forms the partition walls of a predetermined height to adjacent areas of the surface with the fuel pump of the fuel tank mounted on from the floor surface of the fuel tank to allow the fuel to be stored in the partition walls regardless of the driving conditions (the backing, plates, left tilt, right tilt, etc.) to ensure smooth fuel supply to the engine by securing the continuous suction operation of a fuel pump.
[005] However, the assembly, shape, operation and location of the parts mentioned in the prior art are not similar to the present disclosure.

OBJECTS OF THE INVENTION:
[006] The principal objective of the present invention is to provide a fuel tank configured for providing optimum fuel supply to a vehicle engine during low fuel conditions and/or during a turning or cornering of the vehicle.
[007] Another object of the present subject matter is to provide a fuel tank with improved fuel level sensing.
[008] Another object of the present subject matter is to provide a fuel tank with improved stiffness against deformation.
[009] Another object of the present subject matter is to provide a simple, cost effective, and efficiently designed fuel tank that is distinct from all conventional designs.

SUMMARY OF THE INVENTION:
[0010] The present invention relates to a fuel tank for a vehicle. The fuel tank includes a top; a base separated from the top through a first-long wall, a second-long wall, and side-short walls, wherein the top, the base, the first-long wall, the second-long wall, and the side-short walls define a fuel storage space therebetween; a first barrier extending inside the fuel storage space up to a variable depth, the first barrier integrated with the base and the first-long wall, the first barrier originating from the first-long wall and terminating to a zero depth marginally ahead of the second-long wall; a second barrier extending inside the fuel storage space up to the variable depth, the second barrier integrated with the base and the second-long wall, the second barrier originating from the second-long wall and terminating to the zero depth marginally ahead of the first-long wall, the first barrier and the second barrier defining an integrated reservoir therebetween; and a fuel pump suspended from the top positioned substantially in the integrated reservoir.

[0020] Fig. 1 illustrates a cut view of a fuel tank 100 for a vehicle in accordance with an embodiment of the present disclosure. In an embodiment, the fuel tank 100 includes a top 102; a base 104 separated from the top 102 through a first-long wall 106, a second-long wall 108, and side-short walls 110. In an example, the top 102, the base 104, the first-long wall 106, the second-long wall 108, and the side-short walls 110 define a fuel storage space 112 therebetween.
[0021] In an embodiment, the fuel tank 100 further includes a first barrier 122 extending inside the fuel storage space 112 up to a variable depth. The first barrier 122 is integrated with the base 104 and the first-long wall 106. In an example, the first barrier 122 originates from the first-long wall 106 and terminates to a zero depth marginally ahead of the second-long wall 108.
[0022] Further, in an embodiment, the fuel tank 100 includes a second barrier 124 extending inside the fuel storage space 112 up to the variable depth. The second barrier 124 is integrated with the base 104 and the second-long wall 108. In an example, the second barrier 124 originates from the second-long wall 108 and terminates to the zero depth marginally ahead of the first-long wall 106. In an example, the variable depth of the first barrier 122 and the second barrier 124 is less than a depth D of the fuel storage space 112.
[0023] In an example, the fuel tank 100 is made of plastic, and the first barrier 122 and the second barrier 124 are molded in the fuel tank 100. In another example, the fuel tank 100 may be metallic, for example made up of sheet metal, and the first barrier 122 and the second barrier 124 are accordingly provided within the fuel tank 100. Further in another example, the first barrier 122 and the second barrier 124 may be welded with the fuel tank 100. In an embodiment, the first barrier 122 and the second barrier 124 define an integrated reservoir 126 therebetween. Further, the fuel tank 100 also includes a fuel pump 128 suspended from the top 102. In an example, the fuel pump 128 is a centrally mounted hanging type fuel pump. Further in an example, the fuel pump 128 is positioned substantially in the integrated reservoir 126. In an implementation, the first barrier 122 and the second barrier 124 being molded with the fuel tank 100 enact as beads or stiffeners configured to enhance stiffness of the fuel tank 100 against deformation. This prevents provision of additional bead shape or the like structures with fuel tanks 100, thereby providing a simple, cost effective, and efficiently designed fuel tank 100.
[0024] Fig. 2 illustrates different views of the fuel tank 100 as seen from the base 104. As shown, a profile associated with the first barrier 122 and the second barrier 124 includes a J shape. Alternatively, a profile associated with the first barrier 122 and the second barrier 124 may be one of a linear, non-liner, arcuate, semi-linear, semi-arcuate, L shape, J shape, C shape, S shape, I shape, T shape, or the like. As mentioned earlier, the profile associated with the first barrier 122 and the second barrier 124 provides the integrated reservoir 126.
[0025] Figs. 3a and 3b respectively illustrates orientation of the fuel tank 100 during left and right turning or cornering of the vehicle. In an embodiment, the integrated reservoir 126 is configured to hold a fuel volume V during a turning or cornering of the vehicle. Referring back to Fig. 2, the zero depth of the first barrier 122 and the second barrier 124 respectively defines gaps G1, G2 with the second-long wall 108 and the first-long wall 106, wherein during a turning or cornering of the vehicle the gap G1, G2 allows movement of fuel in the fuel storage space 112. Further, due to this movement, the fuel volume V accommodates in the integrated reservoir 126. Hence, availability of the fuel volume V in the integrated reservoir 126 provides an uninterrupted operation of the fuel pump 128 during a turning or cornering of the vehicle, and in turn of the vehicle. Further, the availability of the fuel volume V in the integrated reservoir 126 provides efficient fuel level sensing during a turning or cornering of the vehicle, especially during low fuel conditions.

Rather, the specific features and methods are disclosed as embodiments for the present subject matter. Numerous modifications and adaptations of the system/component of the present invention will be apparent to those skilled in the art, and thus it is intended by the appended claims to cover all such modifications and adaptations which fall within the scope of the present subject matter.
