Description

[0001] “AN ANTI-SLOSHING SYSTEM FOR A FUEL TANK” TECHNICAL FIELD: Present disclosure relates to the field of automobiles. Particularly, but not exclusively, embodiments of the present disclosure disclose a fuel stabilizing apparatus for a fuel tank. Further, embodiments of the present disclosure discloses an anti-sloshing system for the fuel tank. BACKGROUND OF THE DISCLOSURE: In transport industry, the vehicle such as ships, spacecraft, fuel carrying trucks, airplane helicopter and the like while being operated may be influenced by number of parameters that plays a vital role in the maneuverability of these vehicles. Some of the parameters include design of the vehicle, size of the vehicle, weight of the vehicle and the load being carried by the vehicle. The load of the vehicle may either be the number of goods / passengers carried by the vehicle or the fuel used to propel these vehicles. During the transport the vehicle accelerates and decelerates based upon which the velocity of the vehicle changes, consequently the center of gravity of the vehicle changes. Due to the change in center of gravity of the vehicle, the center of gravity of the load also changes. The change in center of gravity of load may cause the load to be unstable for example if the vehicle accelerates and decelerates the fuel inside the fuel tank due to the change in the center of gravity may experience a force which may lead to the instability of the fuel inside the fuel tank. This instability of the fuel inside the fuel tank is known as liquid oscillation or fuel sloshing. Therefore, the vehicle has to be designed in such a manner that the vehicle may easily maneuver with the loads. The fuel sloshing inside the fuel tank plays a vital role in the dynamics of the vehicle. It is important to control the fuel sloshing inside the fuel tank as the same may pose myriad problems including noise in the internal space of the vehicle, inertial loads during travel, structural vibrations, change in center of gravity of the vehicle, etc. Further, the fuel sloshing may also lead to a highly localized impact pressure on the walls of the fuel tank, leading to structural damage. Further, the fuel sloshing may affect the stability and maneuverability of the vehicle. To overcome the aforementioned challenges there are known devices that solve the problem related to the fuel sloshing of a vehicle, for example, a zig-zag arrangement plate defined with holes is installed in the vertical and the longitudinal direction of the fuel tank. The zig-zag plate reduces the sloshing by absorbing fuel movement and also acts as a barrier / partition plate inside the fuel tank. However, the zig-zag plate design is not very efficient during the high speed of the vehicle and the zig-zag plate also fails to prevent the fuel sloshing when the fuel inside the fuel tank is very low. Therefore, there was the requirement for a new type of device which can overcome the problems as disclosed above. Present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the known arts. The drawbacks / difficulties / disadvantages / limitations of the conventional techniques explained in the background section are just for exemplary purpose and the disclosure would never limit its scope only such limitations. A person skilled in the art would understand that this disclosure and below mentioned description may also solve other problems or overcome the other drawbacks / disadvantages of the conventional arts which are not explicitly captured above.
