How to Check if the Fuel Tank is Full or Not?
1 Answers
Both analog and digital fuel gauges require the vehicle to be started before taking a reading. The analog fuel gauge is marked with two letters, E and F. E stands for Empty, indicating the tank is empty; F stands for Full, indicating the tank is full. The closer the needle is to the letter F, the more fuel remains; the closer it is to the letter E, the less fuel remains. When the fuel icon lights up, it indicates that there is not much fuel left, and refueling is needed as soon as possible. Here are some additional details: 1. Function of the fuel gauge: The fuel gauge provides a rough estimate of the fuel level and cannot display the exact remaining amount, serving only as a reference for the driver. For example, a digital fuel gauge might show a remaining range of 300 kilometers, but in reality, due to factors like vehicle condition and road conditions, the actual range might only be 150 kilometers. 2. Components of the fuel system: The fuel system mainly consists of four parts: the fuel gauge, sensor circuit, variable resistor, and float. When the fuel tank is full, the resistance value of the variable resistor connected to the float decreases, and the circuit current reaches its maximum. At this point, the fuel gauge needle is at its highest position. As the fuel level decreases, the resistance value of the variable resistor increases accordingly, the circuit current decreases, and the fuel gauge needle also lowers.
