The fuel gauge light is on, how far can the car go? Can you burn a gasoline pump?

If the fuel gauge light is on during driving, it means that the car is running out of fuel and needs to go to the gas station to refuel. However, in this case, you can usually drive about 80 kilometers to 100 kilometers, which is enough to drive to the gas station to refuel. If you keep driving a car without oil, it won't damage the gasoline pump of the car. However, it will cause the car to run out of gas. If you don't refuel in time, you can only wait for rescue, which will undoubtedly increase a lot of extra expenses.

In fact, the capacity of the fuel tank mainly depends on the model and grade, specifically on the displacement and grade of the vehicle. Then the displacement of small cars is 25 to 40 liters, compact cars are about 40 liters, and larger gasoline cars are 50 to 70 liters. If the fuel tank is full, the driving distance of light cars and small cars is about 300 to 400 kilometers. If the displacement is higher than 2, you can travel about 500 kilometers. Nowadays, in order to improve fuel efficiency and indoor space efficiency, the fuel tank of family cars is getting smaller and smaller.

The design of gasoline pump is very clever, as long as there is fuel flowing through the pump body, it can dissipate heat. As long as the fuel quantity can be maintained, the combustion pump of the engine will not be damaged. When the fuel in the fuel tank is completely drained, no fuel flows through the pump body to dissipate heat, which may cause the oil pump to burn out. In other words, as long as you don't run to the front of the car and turn off the engine, you don't have to worry about burning the oil pump.

For gasoline engines, in order to ensure the normal injection of fuel by injectors, the oil pump needs to provide a large supply pressure. However, the oil pump motor itself is not large, and it is inevitable to produce high heat when working. Although gasoline flows through the motor when the oil pump is working, it can take away heat, but in order to reduce the resistance caused by gasoline flow and protect the enameled wire of the motor rotor from gasoline corrosion, the motor rotor is wrapped with resin material, which has the advantage of isolating gasoline and reducing the flow resistance, but has the disadvantage of affecting the heat dissipation effect of the coil.

When the car is working, the gasoline is constantly circulating, so the oil return pipe of some cars is close to the fuel tank, while the oil return pipe of some cars is on the fuel rail. In the latter case, gasoline must bypass the engine to return to the fuel tank. Because the temperature of the engine is close to 100 degrees, the gasoline is heated invisibly.
