How Long Can You Drive Without Gas?

You can drive about 10 kilometers after the fuel gauge hits zero. Here's an introduction to how to read a car fuel gauge and how it works: How to Read a Car Fuel Gauge: Generally, there are two letters on the fuel gauge: E stands for empty, and F stands for full. Inside the fuel gauge, there are two coils, located on the F and E sides respectively. The sensor is a variable resistor controlled by the float height. The change in resistance determines the strength of the magnetic field in the two coils, which in turn determines the direction of the pointer's deflection. How the Fuel Gauge Works: There is a float ball in the car's fuel tank, which drives a sliding resistor. As the fuel level in the tank changes, the potential at the measurement terminal also changes. The car's instrument processes this signal and displays it, with the corresponding display value representing the remaining fuel in the tank.
