Automobiles in the present day are highly advanced. No need to introduce it. The developments are very high in terms of engine capacity, efficiency, BHP, lighting, braking and much more. The area of the automobile where there is a higher scope of development is “FUEL TANK AND ITS CALIBRATION”. Till date, there are only very few technologies which measure the fuel rate and the amount of fuel present in the tank. Moreover, the existing technologies are not cost effective.
Fuel Tank Calibration
The cutting-edge technologies of the present day in the field of “fuel tank and its calibration” still use float for calculating the fuel level in high-speed automobiles. Using float in stationary or idle containers gives accurate results. But using the same float in automobiles for measuring fuel level is nothing but foolishness. There is no proper methodology till date to measure the fuel rate accurately just because of moving fuel due to varying speed and acceleration due to which ripples are formed in the fuel tank and the fuel always splashes all the fuel tank. It is one of the major problems faced in today’s automobile industry. Every year thousands of complaints are being received by automobile companies regarding the inaccuracy in the measurement of fuel in the fuel tank.
PROBLEMS AND REMEDIES IN FUEL TANK CALIBRATION
Main obstacles are splashes of fuel while in motion due to variable speeds and velocities.
There are two ways to overcome.
- To collect the values of the splashes and deduct it from the float readings. This is very messy and not cost effective. The modern fuel tanks use this method to calculate the fuel percentage present in the fuel tank.
- Restricting the fuel to splash. How to stop splashes in the fuel tank?
We must keep the tank air free when the vehicle in use. Due to the low pressure in the carburettor, the carburettor sucks the fuel from fuel tank. The size of the tank itself says the amount of fuel in the fuel tank and the rate at which the fuel is used by the engine. This is highly accurate. This is also used to avoid the crimes in petrol bunks.
