What damage does fueling without turning off the engine cause to the car?
1 Answers
Fueling without turning off the engine doesn't cause much damage to the car, but it poses safety risks: 1. Since the vehicle's engine is running at high speed, friction can easily generate static electricity, which may ignite flammable gas upon grounding short circuit and rapidly combust; 2. The exhaust pipe of an idling car can reach temperatures of several hundred degrees Celsius, and spilled gasoline during refueling can quickly evaporate when exposed to high temperatures, reaching the ignition point and catching fire; 3. When the engine is not turned off, the fuel pump continues to operate, generating a large number of bubbles in the fuel tank. As more fuel is added, flammable gas may overflow and ignite if exposed to any sparks nearby.
