Should the engine be turned off when refueling?

[LaElliana]

When refueling, the engine should be turned off. The reasons are as follows: 1. If the engine is not turned off during refueling, the concentration of oil and gas mixture around the vehicle's fuel tank will increase. If sparks occur while the car is running, gasoline molecules in the air can easily ignite, leading to a fire. 2. If the engine is not turned off during refueling, the engine will continue to operate. In this case, if a short circuit or leakage occurs in the vehicle's electrical system, the consequences can be very serious, posing significant safety hazards. 3. Refueling without turning off the engine can cause gasoline to spray out when opening the fuel tank cap, and the foam generated during refueling can also be easily sprayed out. If exposed to an open flame, it can ignite immediately, resulting in severe consequences. 4. To prevent fires and unnecessary losses during the refueling process, always turn off the engine before refueling the vehicle.
