Do You Need to Turn Off the Engine and Get Out of the Car When Refueling?

[SanElla]

When refueling a car, it is necessary to turn off the engine, but getting out of the car is not mandatory. Here is the relevant information: 1. Reason: When the engine is running, the vehicle's circuits and electrical systems are powered, with current flowing. If a short circuit or leakage occurs at this time, it can easily cause a fire. 2. Precautions: During refueling, the concentration of oil-gas mixture around the fuel tank increases accordingly. Since the density of this mixture is greater than that of air, when the oil vapor concentration reaches a certain level, any spark generated by the running car engine could ignite and explode it.
