What Causes the Smell of Gasoline Inside the Car After Refueling?
1 Answers
If this situation occurs, the first thing to check is whether you overfilled the tank during the first refueling. When the tank is overfilled, gasoline may flow into the carbon canister through the fuel line. After being soaked in gasoline, excessive gasoline vapor may be released from the vent. If the car's air circulation is set to the outside mode, the gasoline smell can become particularly strong. The carbon canister is part of the Evaporative Emission Control System (EVAP). Under normal circumstances, when the engine is off, the carbon canister absorbs fuel vapors evaporating from the fuel tank and locks them firmly within the micropores of the activated carbon inside the canister, preventing the vapors from escaping into the atmosphere. When the engine is started, the adsorbed fuel vapors in the carbon canister are then delivered to the engine as fuel. If the carbon canister is damaged, it can lead to issues such as poor acceleration, unusual noises while driving, fuel leaks, difficulty starting the engine, and can severely affect the lifespan of various car components. When such issues arise, the carbon canister should be replaced promptly. Otherwise, if the carbon canister fails, the gasoline smell inside the car will become increasingly strong, creating a safety hazard.
