What Causes a Strong Gasoline Smell in the Car Cabin?
1 Answers
Reasons for a strong gasoline smell in the car cabin: 1. Aging of the carbon canister rubber hose; 2. Dirt buildup on the fuel injectors and throttle body due to long-term lack of cleaning, leading to incomplete gasoline combustion; 3. Dirty gasoline filter or loose/aged connecting hose joints; 4. Dirty or failed gasoline vapor canister; 5. Aging or loose fuel tank connecting hoses; 6. Poor vehicle sealing performance. Next to the gasoline filler neck, there is a vent hole for gasoline vapors. Its function is to allow gasoline vapors (formed when the fuel tank temperature rises) to escape, maintaining tank pressure above atmospheric pressure to prevent engine stalling.
