BACKGROUND OF INVENTION
[002] The following description includes information that may be useful in understanding the
present disclosure. It is not an admission that any of the information provided herein is
prior art or relevant to the presently claimed invention, or that any publication specifically
10 or implicitly referenced is prior art.
[003] Internal combustion (IC) engines are widely used in vehicles, powering various modes of
transportation such as cars, motorcycles, trucks, and more. These engines consist of
numerous components that work together to convert fuel into mechanical energy,
15 propelling the vehicle forward. However, the continuous operation of IC engines subjects
their components to wear and tear, leading to potential failures and costly repairs. To
mitigate these issues, ongoing research and development efforts have focused on various
solutions to safeguard IC engine components, enhancing their reliability, durability, and
overall performance.

[004] Conventionally, to avoid any component damage such as a catalyst damage or malfunction
due to irregular fuel supply, a warning is provided in the Instrument Panel Cluster (IPC)
when the fuel level received from a floater-based fuel level sensor falls below a threshold,
typically around 10-15%. However, the current fuel system for fuel level indication has
25 certain limitations. The fuel level gauge used in the system has a large and inconsistent
least count or division, making accurate measurement of the fuel level challenging. The
correlation between the gauge reading and the actual fuel volume is established based on
nominal design specifications without considering part (i.e., fuel tank) variations in each
vehicle. Additionally, factors like vehicle inclination due to its position and volume
30 changes caused by external temperature fluctuations are not accounted for in fuel level
detection. Furthermore, the fuel level at the pump reservoir of the fuel tank is not detected,
3
leading to an inability to monitor steady fuel supply accurately. These above-mentioned
limitations result in an inaccurate prediction of the fuel supply rate and lack of fail-safe
mechanism to protect components from damage, such as melting of catalyst. Further,
implementing fail-safe mechanism like engine shutoff reduces the usable fuel volume and
5 driving range of the vehicle.
