How to Read the Fuel Gauge in a Car?
1 Answers
On the fuel gauge of the car dashboard, the characters E and F are used. F stands for Full, and E stands for Empty. If the fuel gauge needle is at the F position, it indicates that the car's fuel tank is full. If the needle is at the E position, it means the fuel tank is almost empty. When the car is low on fuel, a warning light will illuminate on the dashboard. The fuel warning light usually resembles the shape of a fuel tank. When fuel is low, the warning light will turn yellow; in cases of extremely low fuel, the warning light will turn red. Some car models only display a yellow fuel warning light, in which case the driver should pay attention to the remaining fuel level and refuel in a timely manner. During refueling, it is not advisable to fill the car's fuel tank to the brim, especially in hot summer weather. This is because gasoline expands and vaporizes under high temperatures in summer, and the resulting vapor or even liquid can enter the carbon canister for storage. Overfilling the tank can cause deviations in the fuel gauge needle. Even after prolonged use, the fuel gauge needle may not drop and will only return to normal after some time. Effects of Low Fuel Level: Fuel sloshing causing the car to stall: When the fuel level is too low, fuel can slosh around on bumpy or winding roads, preventing the fuel pump from pumping fuel in time. This can lead to insufficient fuel supply, causing the car to experience shaking, jerking, or stalling. Fuel pump overheating: The fuel pump relies on fuel for cooling. If the fuel level is too low, the cooling performance of the fuel pump decreases, accelerating wear on internal components and potentially leading to short circuits or burning out. Clogging the fuel system: The bottom of the fuel tank contains more impurities. If the fuel level is too low, these impurities can enter the fuel supply system due to fuel sloshing, leading to clogged fuel lines. Impact on driving safety: Low fuel levels can easily cause the car to stall. If the car stalls while driving, both steering and braking can be affected. If the road is busy with traffic, this can easily lead to traffic accidents.
