Must the Engine Be Turned Off When Refueling a Car?

Refueling a car requires the engine to be turned off. Gas stations are inherently areas with dense fuel vapors, and when refueling a vehicle, the concentration of the fuel vapor-air mixture around the fuel tank increases accordingly. When the vapor concentration reaches a certain level and hits the explosion limit, even a small spark can trigger an explosion. Below are some safety tips to keep in mind when refueling at a gas station: 1. Do not use mobile phones. 2. Avoid wearing shoes with nails to prevent sparks from friction. 3. Do not strike metal objects on-site. 4. Do not use plastic containers for fuel. In terms of the fuel flow rate from the nozzle, it dispenses between 35-38 liters per minute, which is relatively fast. When the flowing fuel rubs against the walls of a plastic container, it can generate static electricity, posing significant danger.
