Why Should the Engine Be Turned Off Before Refueling a Car?
2 Answers
The reasons for turning off the engine before refueling a car are: 1. When the engine is not turned off, the engine and other instruments are in operation. Gasoline is an electrolyte, which can easily cause instrument leakage, leading to short circuits or open circuits in the wiring; 2. The exhaust pipe continuously emits exhaust gases, which may carry sparks, creating potential safety hazards; 3. Operating instruments generate a large amount of heat, accelerating the volatilization of gasoline. The concentration of gasoline-air mixture increases and is difficult to disperse, making it prone to ignition and explosion. The correct steps for refueling a car are: 1. Slow down and drive into the gas station at a reduced speed, and drive out at a low speed after refueling; 2. Turn off the engine before refueling; 3. After filling up, close the fuel nozzle before starting the car.
Having driven for a lifetime, I deeply understand the necessity of turning off the engine while refueling. A running engine emits heat and potential sparks, while gasoline vapor is highly flammable. Just a momentary static electricity or electrical spark can trigger a fire or explosion. I remember once at a gas station, a young man nearby started refueling without turning off the engine. Fortunately, I reminded him, or the risk would have been too great. This isn't just about personal safety; other vehicles and pedestrians nearby are also at risk. After making it a habit, I found it also reduces unnecessary engine wear and emission pollution, contributing a bit to the environment. In short, turning off the engine while refueling is basic driving knowledge and shouldn't be ignored for convenience. Before starting every time, I confirm the engine is off to protect myself and others.
