Is it better to fill up the gas tank or not?
1 Answers
It is not advisable to fill up the gas tank completely, as doing so can cause the following hazards: Fuel spillage leading to waste and safety risks: Gasoline storage at gas stations is very stringent, especially during hot summers. Gasoline is stored underground where temperatures are kept low. If the car's gas tank is filled to the brim, gasoline may overflow through the vent hole, resulting in waste. Moreover, spilled gasoline coming into contact with an open flame poses a potential fire hazard. Gasoline evaporation causing unpleasant odors and carcinogenic effects: The charcoal canister is usually located near the fresh air intake of the vehicle's ventilation system. When the tank is overfilled, the charcoal canister becomes saturated, and excessive pressure may cause it to release gasoline-laden air into the cabin, affecting the health and safety of the occupants. Damage to the charcoal canister: The charcoal canister is typically installed between the fuel tank and the engine. Since gasoline is a volatile liquid, the fuel tank often contains vapor at normal temperatures. The fuel evaporation emission control system is designed to direct these vapors into the combustion process and prevent them from escaping into the atmosphere. The charcoal canister plays a crucial role in this process. Overfilling the tank can cause liquid gasoline instead of vapor to enter the canister, potentially damaging it. Vent hole blockage: If the engine fails to start after refueling, or if the car jerks while driving, don't immediately suspect the fuel quality. It's likely due to an overfilled tank causing the vent hole to become blocked. Once the vent hole is obstructed, negative pressure builds up inside the fuel tank, leading to poor fuel delivery or even a complete fuel supply failure.
