Is it okay to fill up the gas tank in summer?
1 Answers
It is not recommended to fill up the gas tank. The hazards of filling up the gas tank in summer are as follows: 1. Fuel leakage can easily cause a fire: The fuel at gas stations is stored underground where the temperature is lower. Especially in hot summer, due to thermal expansion and contraction, if the tank is filled too full, fuel may overflow from the vent hole. 2. Blockage of the vent hole: Once the vent hole is blocked, negative pressure will form inside the fuel tank, leading to poor fuel supply or even a complete stoppage. 3. Harm to the carbon canister: The carbon canister is usually 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 the vapor into the combustion process and prevent it from evaporating into the atmosphere. The activated carbon canister storage device plays a crucial role in this process. If the tank is filled too full, liquid gasoline instead of vapor enters the carbon canister, which can cause damage. 4. Gasoline evaporation can be carcinogenic: The activated carbon canister is usually located near the fresh air intake for the cabin. When the tank is overfilled, the carbon canister becomes saturated, and excessive pressure may cause it to release pressure and exhaust. Air containing gasoline components entering the cabin can inevitably harm the passengers' health.
