Is It Good to Fill Up the Gas Tank Every Time?
1 Answers
Filling up the gas tank every time is not good for the car. Here are the specific hazards of overfilling the gas tank: 1. Gasoline evaporation is unpleasant and carcinogenic: The activated carbon canister is usually located near the air intake of the external circulation system. When the tank is overfilled, the carbon canister becomes saturated, and excessive pressure causes it to release exhaust gas. This allows air containing gasoline components to enter the cabin, posing health risks to the driver and passengers. 2. Damages the carbon canister: The carbon canister is typically installed between the fuel tank and the engine. Since gasoline is a highly volatile liquid, the fuel tank often contains vapor at room temperature. The fuel evaporation emission control system is designed to direct this vapor into the combustion process and prevent it from escaping into the atmosphere. The activated carbon canister storage device plays a crucial role in this process. If the tank is overfilled, liquid gasoline instead of vapor enters the carbon canister, causing damage. 3. Clogged vent hole: If the engine fails to start after refueling, it may be due to an overfilled tank. Once the vent hole is clogged, negative pressure builds up inside the fuel tank, leading to poor fuel supply or even a complete fuel cutoff.
