Many vehicles currently keep the engine and electrical equipment running during refueling, which may pose a series of safety hazards. Is there really no problem with refueling without turning off the engine?
Firstly, there is a risk of electrical leakage when the engine is not turned off, and a short circuit in the wiring may cause sparks, leading to car fires.
Imagine driving to a gas station, hastily grabbing the fuel nozzle without turning off the engine. This small oversight could lead to serious consequences.
The nature of the electrolytic automotive fuel makes electrical leakage a reality when the engine is not turned off. Therefore, the risk of wiring short circuits and sparks becomes very high. Even a tiny spark could potentially trigger a fire in an instant.
Apart from the risk of fire, a vehicle left running during refueling poses other threats. The exhaust pipe continues to expel exhaust gases, and besides the high temperature, the tiny sparks carried during the exhaust pose a life-threatening risk to gas station personnel.
Imagine gas station staff working near the exhaust pipe, refueling vehicles while facing the risk of igniting gasoline and the fuel nozzle. In such a scenario, just a small spark could lead to more severe consequences.
Additionally, electrical equipment inside the vehicle generates a significant amount of heat when the engine is not turned off, causing gasoline in the tank to evaporate more quickly.
When the concentration of the gas mixture around the fuel tank reaches a certain level, even a small spark from the engine could ignite the car, or even the fuel nozzle, resulting in fires and explosions. These are safety hazards that cannot be ignored.
